Are you among the iPhone users experiencing 4G/3G & LTE connectivity issues? Have you tried seemingly every possible solution, but the issue persists? What’s the fix to this 4G/3G & LTE issue?

Speaking of fixes, there are some tried and true tricks that have solved this pesky problem for ages. Let’s give them a shot to fix the issue of 3G, 4G & LTE not working on iPhone or iPad.

How to fix 3G/4G & LTE not working on iPhone or iPad

Check your Cellular Connection

First off, ensure that 3G/4G is enabled on your device. This may sound obvious, but sometimes basic details slip our minds. So, it’s better to check them upfront—you might save yourself a lot of time.

Head over to Settings → Cellular/Mobile Data. Make sure it’s toggled on.

Then, tap Cellular/Mobile Data Options → Enable 4G → Choose Voice & Data.

Turn Mobile Data on/off a few times. It might solve the issue immediately.

Toggle Airplane Mode

Turning on Airplane Mode and then turning it off after a few seconds might solve the 4G/3G or LTE connectivity. To do so: swipe up on the iPhone home screen (On iPhone X Series or later, swipe down from the top-right corner) and Turn On and Off Airplane Mode.

Remove the SIM Card/Restart your iPhone

Sometimes, restarting your phone can automatically fix a few issues. Let’s see if it can help.

Power down your iPhone.

Remove the SIM card and reinsert it.

Restart your phone: Press and hold on the sleep/wake button and when the red slider appears, drag it to switch off your device.

After a while, press and hold the sleep/wake button to power on your iPhone.

Turn off SIM PIN

Note: Some carriers distribute iPhones with SIM PIN enabled by default. Contact your carrier to check your default SIM PIN.

No luck? Contact your carrier and explain the problem.

Contact your carrier to make sure your account is properly set up and there is no problem with your current data plan.

Check the error messages in the carrier logs.

To boost performance or resolve existing bugs, carriers often roll out updates. So, be sure your carrier settings are updated.

Go to Settings → General → About → check the carrier version. If an update is available, download and install it.

Reset Network Settings

Resetting Network Settings can fix 3G, 4G, or LTE not working on iPhone or iPad.

Note: Resetting your Network Settings will remove all the previous preferences such as Wi-Fi passwords, VPN settings, preferred network, etc.

iOS updates have a reputation for solving specific annoying issues.

If you haven’t updated your device in a while or if there’s a software update waiting for you, upgrading might just do the trick.

Plug your iPhone into a power source.

Launch Settings → Tap General → Tap Software Update.

Tap Download and Install → Tap Install.

Restore your iPhone

If all the solutions mentioned above haven’t fixed the issue, restoring your iPhone can work as a last resort. Before moving ahead, back up your device!

Note: Restoring your iPhone will delete all of your data and install the newest version of iOS.

Don’t give up yet if the issue still isn’t resolved. Contact the godfather! But seriously, contact Apple itself.

That’s all!

Htc Evo Design 4G Review: A 4G Phone For The Budget

The HTC Evo Design 4G ($100 with a new two-year Sprint contract, as of November 9, 2011) is the smallest phone in Sprint’s Evo line. It’s also one of the more affordable Evo models currently available on the carrier, but the phone has a few issues surrounding the HTC Sense overlay.


One interesting thing about the Evo Design 4G is that, unlike with previous Evo models, the entire back plate does not come off. To get to the battery or MicroSD card, you need to remove a small panel on the bottom half of the phone. The panel detaches relatively easily, but putting it back on can be a bit of a hassle.


Powered by a 1.2GHz single-core Snapdragon processor, the Evo Design 4G can handle most of the apps and games you might throw at it. While games such as Minecraft or Cordy won’t run as fluidly as they would on a dual-core phone, less-demanding games like Angry Birds Rio should have no issues.

In my tests, iindividual apps ran fine, but things started to get messy when I opened more than four or five. Although the Evo Design 4G has 768MB of RAM, the HTC Sense overlay ties up most of it. No matter how many apps I closed or killed, I couldn’t get the phone to use less than 400MB at any one time. For people who don’t use more than one or two apps simultaneously, this won’t be much of an issue–but the fact that the overlay hogs that much system memory remains unforgivable.

The Evo Design 4G is a dual-band phone that supports both CDMA and GSM connections. That flexibility is useful if you are in an area with low CDMA coverage but great GSM reception. Using GSM networks can cost you extra, though, so you should consult your carrier beforehand lest you rack up sky-high roaming charges.

Call quality over Sprint’s voice network here in San Francisco was a mixed bag. While the calls I placed were free of any static or reverb, audio levels varied. One second I could hear the other person just fine, and the next, they sounded as if they were whispering into their microphone. The mic on the Evo Design did a good job of filtering out background noises, but on occasion it would pick up wind that hit it directly.


Aside from the Sense UI, the Evo Design 4G comes preloaded with a few Sprint-branded applications (TV, NASCAR, TeleNav, and the like), all of which you can uninstall if you don’t want them.


The Evo Design 4G can stream audio, video, or photos to DLNA-compliant devices (such as smart TVs or PlayStation 3 consoles) that share the same Wi-Fi connection. It’s a great feature for sharing your media with a large group of people, but you’ll want to keep your phone plugged to a power source so that the battery doesn’t die in the middle of streaming a movie for your friends.


Like most modern smartphones, the Evo Design 4G sports both front-facing and rear-facing cameras. The front-facing 1.3-megapixel camera, meant for use with video-calling applications like Qik or Tango, produced surprisingly clear video in my tests.

The rear 5-megapixel camera comes with a basic photo editor. It replicated colors well, but images could have been a bit sharper. The Evo Design 4G is capable of recording in 720p, too, but my videos suffered from a mild lag when I panned the camera. Nevertheless, the camera is serviceable enough for snapping everyday photos or catching a quick clip for YouTube.

Bottom Line

Nokia 8110 4G Review: Hands

Our Verdict

It’s true that smartphones aren’t much more expensive, even the new Nokia 1, but that doesn’t stop the new 8110 4G from being an alluring phone. It’s different and fun while offering some modern features like voice calls over LTE and Wi-Fi hotspot. Of course, the device isn’t going to set the market on fire but it’s still nice to a continuation of this original series. Long time Nokia fans will be tempted out of notstalgia, while others might legitimately find this a useful phone for festivals or for those who find a smartphone too overwhelming.

MWC might usually be about  smartphones and other high-end gadgets but a feature phone has caused quite a big of hype. HMD has re-launched the Nokia phone seen in The Matrix. Here we go hands-on with the Nokia 8110 4G. 

Let’s face it, sometimes old things are cooler than new one and although the Nokia 8110 4G is technically a new phone, it’s another example of the firm bringing back a classic. (And now the Nokia 2720 Flip is back too.)

Following the Nokia 3310, this is the second ‘retro classic reloaded’ and although it’s been 22 years, the Nokia 8110 is back.

Although Nokia’s other new phones, like the 8 Sirocco and New Nokia 6, arrived in April, the 8110 4G was a late comer.

It originally had a fairly loose release date of May but has now available to pre-order in the UK with a release date of 15 August.

According to the original 8110 was priced at £200, but the new 4G model won’t cost you that much in 2023. The RRP is £69.

It costs £49 from Carphone Warehouse with a £10 top-up. You can also order it from Amazon.

So it’s very  cheap phone, like the 3310, and will make a decent option for those looking for a feature phone in situations like festivals or perhaps for an elderly user.

Design and build

In a similar vain to the Nokia 3310, the new Nokia 8110 is similar in design to the original, yet tweaked so it’s also quite different. And yes, this is the phone used by Neo in the first Matrix movie! 

Gone is the original stumpy antenna sticking out the top, as you would imagine, and the buttons are a new design also. They’re much flatter and all very close together where the original had separate keys. There’s now a D-pad instead of the up and down buttons from before.

The 8110 4G is still curved in shape and fits around your head very well. After all, this phone is designed for calls unlike smartphones. Of course, the curved banana shape means that it doesn’t sit nicely on a desk or in your pocket but you can spin it round helicopter style for enjoyment.

Also true to the original is the slide out cover that hides the buttons when shut. It’s got a smooth and quite satisfying action so you’ll no doubt find your self opening and closing it over and over again just for fun.

It’s not just for protection either, as you can legitimately use the cover to answer and end phone calls. Does it get more hipster than that?

This new model is a fair bit thinner and lighter than the original – 14.9mm vs 25mm and 117g vs 152g.

A banana phone wouldn’t be a proper banana phone without coming in the aptly named Banana Yellow. As you can see it’s not the kind of handset you’re going to lose easily, but does also come in Traditional Black if you want that Matrix style. 

Specs and features

One of the biggest and obvious differences between this 4G 8110 and the original is the more modern screen. It’s a bit bigger at 2.4in and offers colour instead of monochrome. 

It’s curved and isn’t touchscreen but has a reasonable QVGA resolution (240×320). There’s no IPS technology at this price so TN is understandable but means not the best viewing angles.

In terms of the slightly boring specs, the new 8110 4G runs on a Qualcomm Snapdragon 205 – that’s a 1.1GHz dual-core that’s got plenty of power to run Snake.

The phone also has 512MB of RAM, 4GB of storage and some basic things like Wi-Fi, Bluetooth 4.1, GPS and a microUSB port.

In terms of modern features, the standout is 4G support and the ability to use the 8110 for VoLTE – or voice over LTE calls. You can also share that data connection via a Wi-Fi hotspot so the 8110 could be a good phone to use as a secondary device. 

Yes, there’s a camera but it’s a pretty dismal 2Mp so don’t expect anything every remotely putting on Instragram unless you want a really retro look.

Although the battery is 1500mAh – pretty small for 2023 smartphones – this is a feature phone so doesn’t guzzle power in the same way. In fact, Nokia says it will last a whopping 25 days on standby.

In usage you’ll get over nine hours of VoLTE calls, six hours of video playback (not that you would) and 48 hours of mp3 playback. 

There’s no Google Play store here so you can’t just download all the apps you’d normally use on your Android smartphone but the 8110 does have an app store in the Smart Feature OS which includes the likes of Facebook, Twitter, Google Maps and Google Assistant. 

It wouldn’t be a reimagined classing without Snake so that’s pre-loaded.

Leagoo Elite 5 4G Phablet Review

It’s not hard these days to find an affordable Android device, but not all of them have decent specs or are attractive. Many of them are also slow since they don’t come with much RAM or ROM. Affordability is, of course, subjective, but to me anything under $200 is a good deal when it comes to gadgets.

The Leagoo Elite 5 is a device that falls in this price range (it’s actually under $150) and has great specs and a unique look to boot. This 4G phablet boasts a 5.5-inch screen, 2GB RAM, 16GB ROM, great quality cameras (both front and back), and a huge battery.

Leagoo was nice enough to let us test this model for a few weeks, and I’m quite impressed with the phone overall. Considering the price point, it’s definitely worth a look if you’re in the market for an affordable Android device for a loved one, children, or even yourself.

What’s in the Box

The Leagoo Elite 5 box includes:

Elite 5 smartphone and battery, available in lemon yellow, rocky black, and ivory white

European plug adapter

Wired earbuds with microphone

Micro-USB charging cable

Micro-USB OTG adapter (USB 2.0 to micro-USB adapter convert connector)

Instruction manual

The Basics

Unlike the Leagoo Alfa 1 that I reviewed in April, this device does have 4G support and is incredibly fast as long as you’re within a 4G network (it’s in and out in my area). It’s unlocked and supports the use of two SIM cards (most users will only need one).

It should be noted that with an unlocked device like this, only GSM networks like AT&T and T-Mobile are supported in the U.S. I’ve tested it with Straight Talk (which offers both AT&T and T-Mobile based sim cards) and had no issue.

The device uses Leagoo’s own 64-bit OS 1.1 which features enhanced battery life, an improved user interface, guest mode, power saving mode, smart lock function, and much more. I have really enjoyed Leagoo OS 1.1 and find it easy-to-use and customize, as well as incredibly snappy. I’m normally not a fan of default launchers but this one’s a keeper in my book.

I also want to point out that this device does have a notification light. Many phones have this and many don’t. My current device doesn’t have this feature, and I wish it did. It’s nice to have a customizable LED that flashes when you have a missed call, new text message, new email, etc.

Notable Features

Even though the Elite 5 has all the features you’d expect from a budget Android device, it does have a few notable features that make it stand out from other budget devices. Here’s a look at each one.

Universal Infrared Remote Control Function

The Elite 5 can be used as a remote control thanks to an independent infrared remote control chip in the device. You can use it to control your TV, STB (set-top box), DVD player, air conditioner, projector, SLR, and much more. It supports over 800 manufacturers and more than 20,000 product models.

It’s extremely easy to set up remote control functions with most devices thanks to the included “Smart Remote” app (but any IR app in the Google Play Store should work just fine). I find it to be very accurate and responsive with both TVs in my home. Plus, it doesn’t need an active Internet connection to work, so no matter where you are you can still use the remote function.

I have this remote feature on my Samsung tablet, so I already know how handy it is, and I use it quite often. I appreciate it even more on a smaller device that can fit in one hand. It’s especially fun when you go to a family member’s or friend’s house and start secretly messing around with the TV; they’ll think that the TV is malfunctioning. I’ve gotten a few people like this, and it was hilarious!

4000mAh Ultra-Large Capacity Li-Polymer Battery

A 4000mAh battery isn’t very common when it comes to smartphones, so it’s surprising to have such a large capacity battery in a budget Android device. It’s definitely appreciated, though.

I didn’t set up any apps that constantly run in the background on the device (i.e. Facebook, Gmail), so the battery life has been really good; it has only needed to be charged every 2-3 days. Even when playing resource-heavy games, the battery doesn’t shoot down quickly like it does on my tablet.

The battery also charges really fast thanks to its unique LFC flash charge technology, 2A charging current, and TI intelligent charge management chip. It takes around two hours to fully charge the device, which is almost twice as fast as my current smartphone with just a 3000mAh battery.

Functions as a Power Bank

The Elite 5 also has a unique reverse charging function that allows you to use it as a power bank to charge other micro-USB devices. This is thanks to the included adapter that converts the USB end of a charging cable to micro-USB (since both ends need to be micro-USB for charging).

Being able to use the device as a power bank eliminates the need for an external battery or power bank when on the go. Unless, of course, your device has a battery larger than 4000mAh or you’re going on a trip; in that case, it just makes sense to use a larger capacity power bank instead.


Dimensions: 154.6*77.0*8.9mm (L×W×H)

Weight: 176g

Display: 5.5-inch HD IPS OGS; multi-points capacitive touch

Battery: 4000mAh ultra-large capacity polymer battery; also functions as a power bank

SIM Card: Dual SIM dual standby

Network: 2G: GSM 850/900/1800/1900MHz; 3G: WCDMA 900/2100MHz; 4G: FDD-LTE 800/900/1800/2100/2600MHz

Final Thoughts

I really only have one complaint about the Elite 5 and that’s the fact that the navigation buttons (home, back, menu) don’t light up, so they’re difficult to see in dark and dimly lit areas. Additionally, since the buttons are the opposite of my smartphone and tablet, I kept getting them mixed up. On this device the menu button is to the left of the home button, and the back button is to the right of the home button.

Besides that, I think this is a great device. If you could care less about the most trendy or latest and greatest smartphone, this is one that’s stylish, extremely functional and light on your wallet.

Sagem Orga Simfi Embeds Wifi Onto A 3G Sim Card

Sagem Orga SIMFi embeds WiFi onto a 3G SIM card

What if, rather than buying a MiFi or using a WiFi router app like on the Palm Pre Plus, you could stick a SIM in any device and have a shared 3G connection?  That’s what Sagem Orga and Telefonica are promising; they’ve developed the SIMFi, a USIM card with an embedded WiFi radio that, when dropped into any standard handset, can share the 3G HSPA connection with various WiFi clients as an instant access point.

The SIMFi uses SIM toolkit applets running on the card itself, meaning there’s no setup hassles or handset-specific configuration.  Instead users would presumably change any access point settings – security, for instance – via the SIM menu in the first device they slot the SIMFi into, and then use it plug-and-play from that point on.

It’s a promising idea, and we’re guessing that with Telefonica on board the SIMFi will be seeing a commercial release rather than floating around as a proof of concept we can’t get hold of.  No word on what sort of price each of the modules commands, but it seems likely that carriers would give the SIMFi away as long as you took out some sort of mobile data contract.

Press Release:

World premier: Sagem Orga and Telefonica turn the SIM card into a Wi-Fi hotspot

Barcelona, Mobile World Congress 2010

Smart card expert Sagem Orga (Safran group) and Telefonica, one of the world’s largest telecommunications companies, are enhancing mobile broadband services by offering “SIMFi,” the first SIM card with integrated Wi-Fi. Using the SIM as a hotspot is expected to have the potential of becoming the next killer application.

Millions of subscribers are using netbooks and notebooks to surf the Internet while on the move, and this has become a strategic market for mobile operators. To enable Internet access, all of these mobility devices use the USIM card to authenticate the user on High Speed Packet Access (HSPA) networks, but there are some drawbacks that are slowing down market penetration. These include complex 3G modem and driver set-ups the user must perform, the use of accessories and cables such as USB modems, PCMCIA modems, handsets and certain software, and the complexity of service use.

By turning the SIM card into a Wi-Fi hotspot, Sagem Orga and Telefonica have developed a solution without all these hurdles. An embedded WLAN modem in the SIM card, driven by the SIM toolkit applets running in the SIM, will enable Telefonica to broadcast High Speed Packet Access (HSPA) Internet access through Wi-Fi to notebooks and netbooks. The new generation USIM card “SIMFi” can be inserted in any type of classic handset to act as a universal and interoperable HSPA/Wi-Fi router for any device.

“We strongly believe that SIMFi, with its unprecedented functionality for wireless access, will significantly improve the user experience,” explained Remy Cricco, Technology Innovation Manager at Sagem Orga. “If customers can connect their notebooks to the Web anytime and anywhere by simply using what they have with them most of the time and what is the most trusted secure device – the SIM card – adoption can be expected to be enormous.”

Samsung Epic 4G Touch Android 4.1.2 Jelly Bean Update

Sprint has become the first US carrier to roll out the official Android 4.1 Jelly Bean update to a Galaxy S2 variant – the major update is now available for the Epic 4G Touch via Samsung’s Kies PC Suite, carrying the build number GB27.

The Jelly Bean update includes all the expected changes that we’ve retrodden plenty of times – smoother interface aka Project Butter enhancements, Google Now, enhanced notifications, improved browser performance, resizable widgets, ability to disable notifications for individual apps, enhanced accessibility, offline voice typing, and improved under the hood performance and stability.

Being a major update, Sprint has decided not to make it available over the air due to its size, so hooking your phone to a computer is the only way you can upgrade. If you don’t want to use Kies or prefer to manually upgrade, you can use our step-by-step guide to do so, which is specially useful if you’re currently running a custom ROM but want to make the jump to the official update.

Let’s take a look at how to update the Epic 4G Touch to the official Android 4.1 Jelly Bean upgrade manually.


The procedure described below is only for the Samsung Epic 4G Touch on Sprint, model number SPH-D710. Do not try it on any other device.


The methods and procedures discussed here are considered risky, so try them out at your own risk, and make sure to read each step carefully before attempting anything. We will not be held responsible if anything goes wrong.

How to Install Android 4.1.2 Jelly Bean on Epic 4G Touch

Extract the file downloaded in step 3 on the computer to obtain a file named KIES_HOME_SPH-D710.GB27_D710SPRLS1_1014481_REV00_user_low_ship.tar.md5 (the file name may end at .tar, which is normal). This is the actual firmware file that we need to flash on the phone.

Extract the contents of the file to a folder on your computer.

Now, turn off your phone and wait for it to shut down completely.

Then, put the phone into download mode. To do so, press and hold these keys together: Volume Down + Power till the phone turns on and shows a Warning!! screen. Then press Volume Up to enter download mode.

Important! Connect your phone to PC now. You should get the message “Added !!” under Odin’s message box in the bottom left.

If you don’t get this message, make sure you installed drivers correctly (using Kies or directly) as given in step 2. If it still doesn’t work, try changing to another USB port on the computer and also use the USB ports on the back if you have a desktop PC.

Important! Do not make any other changes in Odin except selecting the required files as given in step 11. Leave all other options as they are. Make sure Re-Partition check box is not selected.

What do if Odin gets stuck or doesn’t do anything: If ODIN gets stuck on setup connection or at any stage of this process after you’ve hit the Start button, and doesn’t seem to be doing anything, or if upon completion of the process you get a FAIL message (with red background) in ODIN, do this: disconnect the phone from the PC, close ODIN, remove battery for 4-5 seconds, re-insert it, turn phone on in Download mode again, and do the procedure again from Step 9.

[Important] What to do if phone doesn’t boot: After you get the PASS message and the phone reboots, the phone might get stuck at the booting animation. If that happens, perform the following steps to make it boot. Remember that these steps will wipe your personal data like contacts, apps, messages, etc. If your phone has already booted, stop reading the guide here, your phone has been updated successfully:

Boot to recovery mode — for which, first power off phone (by removing battery and reinserting it), wait for 5-6 seconds, and then press and hold Volume Up + Power keys together till the screen turns on, then let them go to boot into recovery. Once you are in recovery mode, use volume keys to move the selection up and down and home/power key to select the option.

Go to Wipe data/Factory Reset and select it. Select Yes on next screen.

Then, select reboot system now to reboot the phone, which will now boot properly.

If you run into any roadblocks while flashing the firmware, let us know and we’ll help you out.
