T-Mobile Not Working: How To Fix In Seconds? (10 Ways)

When it came to choosing a phone plan, I didn’t give much thought to which service I should use. T-Mobile was my first smartphone provider, and I stayed with them for years. However, while I was traveling recently, my data services abruptly stopped working.

Instead of calling customer service right away and asking for assistance, I decided to check the device’s settings to see if there was a problem. I had an idea of what could have gone wrong, but I decided to do a little research before fiddling with the settings.

If T-Mobile is not working, your connection may be experiencing LTE issues as a result of data limitations, poor coverage, or 4G compatibility issues. To resolve the issue, try re-inserting your SIM card, activating/deactivating airplane mode, configuring an APN, or changing the network settings.

1. Data Sufficiency

You are assigned a data usage limit based on the mobile plan that you have purchased. Your device’s ability to access mobile data is determined by the package you have purchased.

As a result, if you have used up all of your data, you will be unable to access LTE until your plan is renewed the following month.

2. 4G Band Capability

Each device has a different band capability. Therefore, if you are in an area where LTE frequency bands are unavailable or are already occupied, you might face a disruption in the connectivity.

Other frequently faced issues include:

  • Low data coverage in an area.
  • Scarce signals.
  • Improper network or APN settings.
  • Service outage.

3. Check if You are in a Coverage Area

If you have a problem with your T-Mobile, the first thing you should do is check and observe the cellular coverage in your area.

For example, if there is no nearby mobile tower or if you are in a remote area with many trees, forests, or mountains, you may not have adequate coverage.

Obstacles such as trees and mountains have an impact on cellular coverage in a given area. Go to settings and select cellular data to see if you have network coverage. Here you will find information about network coverage in your current location.

In addition, you can look at the T-Mobile coverage map. Despite the fact that the network has grown significantly in recent years, there are a few gaps where you may not receive adequate coverage. The coverage gaps are indicated on the T-Mobile coverage map.

4. Check T-Mobile’s Outage Report

If you are in an area where T-Mobile has coverage but are still experiencing problems, there may be an outage in the area.

Outages are uncommon, but they do occur. Downdetector and other similar websites can be used to determine whether or not there is an outage. They keep track of outage reports from across the country.

If a network outage is reported anywhere in the country, the website will notify you. Furthermore, if you believe you are in an area where there is an outage, you can report it on the website.

5. Turn on Airplane Mode and turn it off

If there is no outage in the area and you have adequate coverage, but you are still experiencing network issues, turning on airplane mode for a few minutes and then turning it off may resolve the problem.

You may notice that your device is stuck at 3G or E instead of 4G. Turn on airplane mode to resolve the issue.

You can do this through your phone’s settings or the quick menu. Airplane mode disables your smartphone’s ability to connect to a network. As a result, turning off airplane mode refreshes the network settings.

6. Remove and Re-insert SIM Card

If the issue still persists, try removing and re-inserting the SIM card. To properly remove the SIM card, follow these steps:

  1. Turn your phone off.
  2. Remove the SIM card.
  3. Wipe it off properly.
  4. Wait for a few minutes.
  5. Re-insert the SIM card.
  6. Turn the phone on.

You will most likely receive a few messages from the network carrier prompting you to install some files regarding data connection. Install the files and turn on the data.

7. Restart Your Phone

If you don’t want to remove the SIM Card for whatever reason, simply restarting the phone may suffice.

However, do not select the option to restart. Instead, turn off your phone for a few minutes before turning it back on. Don’t use the phone or change the settings until it has properly rebooted.

8. Check for Updates to Carrier Settings

If you are not prompted to install any files after reinserting the SIM card and restarting your phone, manually check for a carrier update. To check for and install any updates, follow these steps:

  1. Go to Settings.
  2. Select General.
  3. Tap About.
  4. Go to the Carrier Settings Update.
  5. If there is an update, you will see it under the heading. Tap it to install the files.

9. Change APN Settings

If neither of the above methods work for you, you may need to change the APN settings on your phone.

To change the settings on iOS, do the following:

  1. Navigate to the Settings menu.
  2. Choose Cellular Network.
  3. Navigate to Mobile Data and select Mobile Data Network.
  4. You can reset the settings by manually entering the APN settings listed below.
  • Name: fast.t-mobile.com
  • MMSC: mms.msg.t-mobile.com/mms/wapenc
  • MNC: 260
  • MCC: 310
  • Type of APN: Default, Supl, Hipro, Fota, MMS
  • APN Protocol: IPv6
  • Roaming: IPv4

To change the settings for Android, follow these steps:

  1. Go to settings.
  2. Select Connections.
  3. Go to Mobile Networks and then Access point names.
  4. You can reset the settings here by manually entering the following APN settings.
  • Name: fast.t-mobile.com
  • MMSC: mms.msg.t-mobile.com/mms/wapenc
  • MNC: 260
  • MCC: 310
  • Type of APN: Default, Supl, Hipro, Fota, MMS

10. Reset Network Settings

You can only reset the network settings on Android phones. To reset the settings, follow these steps:

  1. Go to settings.
  2. Select General Management.
  3. Select reset.
  4. Note that make sure you don’t select Reset all settings. This will remove all data from your phone.


Basic troubleshooting may assist you if you receive a ‘no signal’ or ‘no service’ error. Follow these steps to troubleshoot your T-Mobile device:

  1. Restart your computer or device.
  2. Check to see if the signal bars are visible.
  3. Change the Calling preferences to Cellular only in the settings. This will eliminate Wi-Fi Calling problems.
  4. Switch off the Wi-Fi.
  5. Switch the Network Mode setting from Network Settings to Auto.
  6. Activate VoLTE.
  7. Uninstall programs such as all blocking, launcher, and home screen apps.
  8. Upgrade the device’s software to the most recent version.


If you are unable to receive or make calls, or if you are constantly receiving a busy tone, ensure the following conditions are met:

  • The number you are dialing does not begin with the prefixes 1-700, 1-900, or 976.
  • The number you’re dialing isn’t on your blocked or spam list.
  • In the dialer, you are entering an 11-digit number.
  • Dial *67 before the 11-digit phone number to disable caller ID.


It is normal for T-Mobile calls to drop after four hours. If shorter calls are dropping, try the following solutions:

  1. Check to see if you have adequate coverage.
  2. Ensure that the screen does not come to life during the call.
  3. Take off the phone’s case.
  4. Upgrade the software to the most recent version.


If none of the methods mentioned in this article work for you, contact customer service. Perhaps there is a problem with your SIM card. SIM cards, like SD cards, can become corrupt. In this case, you must obtain a new SIM card from the carrier.

If your SIM card is fine but you can’t get it to work, contact customer service. They will request the serial number or IMEI number of your phone. Based on this, they will determine your location and provide you with information about the current situation you are in.

Furthermore, if you have other wireless connections on your phone, they may interfere with the cellular connection. So, turn off your Wi-Fi and Bluetooth to see if the problem is with your phone or your connection.
