Why my mobile network is not working?

Download Article Some ways you can fix the “Mobile network not available” error on your Android Download Article Are you getting a “Mobile network not available” error on your Android phone? Don’t worry because there are a few simple tricks you can try to solve this! This wikiHow article lists a few different tricks that you can use to fix the “Mobile network not available” error.

There are a variety of reasons why you’d get the “Mobile network not available” error including glitches in your settings, tower service, or billing issues.
The easiest, fastest, and most reliable fix is to turn on and off Airplane Mode on your Android and then restart it.
Take out, clean, and reinsert your SIM card to refresh that connection.

1 Toggle Airplane Mode. Turn Airplane Mode on and off, which will also restart your cellular data network on your phone.
- Go to Settings > Network & internet/Connection & sharing > Airplane Mode and tap the switch to toggle it on and off again. You can also swipe down from the top of your screen and tap the airplane icon.
2 Restart your Android. If turning on and off Airplane Mode didn’t work for you, try resetting your phone. The error may be caused by an older background app or temporary file that’s clogging up your system and restarting should clear the issue.
- To restart your phone, press and hold the Volume Down and Power button for about 10-20 seconds or until your phone shuts down (the screen will be black). Let go of those buttons, and you should see the Android logo as your phone restarts.
- Tip: Sometimes, turning your phone off rather than just restarting can do the trick. A restart will sometimes hold onto old info while a turn off/turn on will give the phone an actual full refresh.

3 Remove and clean the SIM (if you have one). If restarting your phone didn’t work, your SIM card may have jostled out of place or is reading poorly. If your phone uses an eSIM, skip this step.
- To remove your SIM card, turn off your phone, then use a small, pointy tool, like an unbent paperclip, to eject your SIM tray. After the tray is ejected, gently remove your SIM card, and clean it (wipe down the metallic surface with a disinfectant wipe or a cotton swab dipped in rubbing alcohol). Reinsert it and turn your phone back on.
- If your SIM looks really dirty or grimy, you may need to replace it,
4 Update your software. If you haven’t updated in a while, you might run into some issues.
- Updating is easy! Simply go to Settings > Software Update/About Phone > Download and Install, You phone will restart to apply the update.
- To make sure that you get the update, connect to Wi-Fi instead of using mobile data, which gives you the error.
5 Turn off Data roaming. Roaming takes over when you’re not in an area covered under your plan’s cellular data, like if you’re traveling internationally. If you have roaming on and you’re always in coverage from your provider, you may get error messages.
- To turn Data roaming off, go to Settings > Network & internet/Connections > Mobile Networks > Roaming and tap the switch to toggle it off.
6 Move to a different location. Maybe your phone’s signal is blocked by a thick wall that has metal in it, or you’re in an area with poor reception. If you can, get to another location for better signal strength.

1 Reset network settings. Sometimes your network settings are a little jumbled and resetting it is what you need to fix your Android’s error. When you reset these settings, you won’t lose any data or saved files, but you will lose your password or any manual settings that you applied to the network.
- To reset your network settings, go to Settings > System/General management > Reset > Reset WiFi, mobile & Bluetooth/Reset network settings > Reset settings, Your phone will restart with network settings reset to default. Try connecting to the internet again or making a phone call to see if you get the “Mobile network not available” error.
2 Switch mobile network operators (not available on some devices). Usually, your phone automatically detects which mobile network is best for you to use. But this can sometimes mess up.
- To switch mobile network operators, go to Settings > Connections > Mobile networks > Network operators > Automatic or Manual, If you’re already on Automatic, pick Manual. If you’re currently on Manual, pick Automatic.
3 Change network types. If your phone uses 5G and that is unavailable near you, you can opt to use LTE specifically. Don’t use this menu if you’re unsure of what you’re doing.
- To change network types, dial *#*#4636#*#* and a new menu will appear. Tap Phone information > Run Ping Test and after you get that information, tap Set preferred network type and select either GSM, LTE, or LTE/UMTS options. If you still get the error, you can change which network type you’re using. If none of them work for you, change it back to the default.
4 Factory reset. Resetting your Android to factory settings will delete all your personal information, but it will also restore apps, files, and default settings.
- You should first make a backup of your current Android’s settings and files. To create a back up, go to Settings > Accounts & Backup > Back up Data > Back up now,
- To reset, go to Settings > General management > Reset > Factory data reset > Reset, Enter your PIN if prompted.
5 Contact your service provider. If you’ve tried everything here but are still getting a “Mobile network not available” error, there might be something wrong with your account. Maybe your provider turned off your mobile network due to payment issues or the tower in your area is down and you didn’t know!

Why is my 4G not working on my Android?

Eject, clean, and reinsert your SIM card – Moving forward, you may need to clean and reinsert your SIM card now to fix the “4G not showing” issue.

Why is my mobile data not working on my Samsung s20?

Samsung Galaxy S20 Network Issues If your phone is having trouble connecting to a cellular or WiFi network, has problems with mobile hotspot, isn’t receiving mobile data, or has issues maintaining a cell signal, this problem page will help get you connected and back online in no time! Occasionally, Samsung phones experience a bug that halts network connection to the phone.

This leads to the phone not receiving any mobile data, despite showing an active (and perhaps even strong) connection to the network. To reset your phone’s network connection, simply toggle Airplane mode on for 30 seconds. Upon turning Airplane mode off, your phone should reestablish its connection to the network and fix any hangups you might have been experiencing.

To toggle Airplane mode:

Swipe down from the top of the screen to open the Quick Settings Panel,
Tap the Airplane Icon to turn on Airplane mode.
Wait 30 seconds for the phone to completely disconnect from any networks.
Tap the Airplane Icon again to turn Airplane mode off.

Note that this will usually only solve cellular network connection issues, rather than WiFi issues. To reset a WiFi network hangup, you may need to forget and reconnect to the network. To do so:

Open the Settings app on your phone.
Select the Connections option at the top of the menu.
From the Connections menu, select the Wi-Fi option at the top.
- The Wi-Fi option may have a toggle on the right side, but you should be able to tap on the left side of the menu bar to open the WiFi menu.
Tap on the gear icon to the right of the network you want to connect to to open a detailed menu for that connection.
Select Forget in the bottom right corner with the trash can icon.
Then reconnect and reconfigure your network settings to fix the issue.

It may be possible that the reason your phone isn’t receiving data is that there isn’t any data available in the first place. If there’s an issue with your WiFi network or your mobile data provider, your phone won’t be able to receive data through no fault of its own.

You can check that your WiFi network is working by attempting to connect another device to the network. If you are able to connect to the network, try loading a few pages that update frequently to ensure that the device is receiving data from the connection. If the other device is also having trouble connecting or accessing data from the network, you can try to fix the issue by reseting your modem and router.

To do so:

Unplug the modem.
Unplug the router.
Wait 30 seconds, counting slowly so that the devices have time to reset completely.
Plug in the modem.
Plug in the router.
Wait a few seconds for the devices to initialize before trying to connect again.

If reseting your router doesn’t work, get in touch with your internet service provider to ensure there aren’t any outages or shutoffs. You can check that your mobile network is working by getting in touch with your cellphone carrier’s support line. You can find support links for popular providers here: It’s possible that the reason you can’t connect to your mobile network is that you’re out of the country in which you purchased your plan.

If you are traveling, be sure to check your carrier’s roaming service to ensure you’ll have coverage. If you have confirmed that the problem isn’t on the provider’s end, and have reset your network connections to eliminate hangups, the problem may be with the software or componentry of your phone. If you’ve been messing around with your phone’s settings recently, it’s possible that you may have changed something you shouldn’t have in the network settings, which is preventing your phone from establishing a solid connection to the network.

If you know a bit about network settings, you can try to go back in and fix any mistakes you might have made, but for the uninformed, reseting the network settings on your device should return everything to the functional default settings. To reset the network settings on your phone:

Open the Settings app.
Select the General Management option from the settings menu.
Select the Reset option from the general management menu.
Select the Reset Network Settings option.
Hit the blue Reset Settings button to confirm your choice.

Sometimes a software or firmware glitch can prevent your phone from connecting to a network. Although a rarer phenomenon, it’s important to rule out before you start opening up your phone and replacing components. You can solve hiccups in the firmware by restarting your phone.

You can restart your phone by holding the power button for three seconds, then tapping the restart button twice. If a normal restart of the phone didn’t help and you really suspect that a software glitch is what’s causing your network issues, you can go a bit further to perform a factory reset of the phone.

This will completely restart the operating system of the phone and eliminate any glitches that may be occurring, but will also clear any settings or data you had, so it’s important to perform a backup of all data you wish to keep before a factory reset,

Open the Settings app.
Select the General Management option.
Select Reset from the general management menu.
Select Factory Data Reset,
Scroll to the bottom of the screen and tap the Reset button.
Confirm your choice by selecting the Delete All button.

If nothing else seemed to solve your connection issues, the problem may lie with one of the chips used to make or manage network connections. If your phone experienced a significant impact or water ingress soon before you noticed connectivity issues, it’s likely that your connectivity issues stem from a hardware malfunction.

Fortunately, all of the chips that handle network connections reside on the same motherboard, so you won’t have to narrow the problem down to an individual chip. Instead you can replace the motherboard to fix the issue. If your phone is still under warranty, this may be something that you can have your carrier do.

If not, we have straightforward guides to replace the motherboard in your Galaxy S20, S20 Plus, or S20 Ultra: Haven’t found the solution to your problem? : Samsung Galaxy S20 Network Issues

Is it safe to reset mobile data?

Will I Lose Anything if I Reset Network Settings? – It’s important to emphasize a network settings reset is not the same thing as a factory reset. Resetting your network settings clears out all of your internet, local network, and paired devices’ data.

A factory reset will delete pretty much everything on your device, reverting it to the state it was in when you unboxed it. A network settings reset will not delete any files, folders, or other media stored on your device. Nor will it delete any web browser data, such as your browsing history or saved bookmarks.

Here’s what a network settings reset deletes:

Wi-Fi network names and passwords.Bluetooth device connections and preferences.VPN settings, local history, and preferences.Cellular network preferences such as data management and 4G/5G settings.

Resetting network settings on an iPhone or Android smartphone will not delete any mobile carrier functionality or account information. The process resets any changes to mobile preferences you may have made since you activated your device. Your ability to make phone calls, send texts, and access apps will not be affected by resetting your network settings.
