Why T-Mobile Phone Not Registered On Network?

If your phone isn’t connecting with the T-Mobile network, then this means your SIM card doesn’t make contact.

In other words, if the SIM card wasn’t recognized by your phone, it won’t connect with T-Mobile’s network.

Here are some of the most frequent causes that might be preventing you from connecting to the T-Mobile network:

Wrong Frequency

If your T-Mobile plan doesn’t support a certain frequency, you won’t be able to connect with the given signal.

No Coverage

In case you’re in a place where your phone cannot acquire service, T-Mobile’s network will become unreachable.

Sim Card/Slot Problem

An issue with the SIM card or the slot of your phone might prevent you from connecting with T-Mobile.

Network Mode isn’t Updated

Lastly, the network mode will determine the service of your provider and if it remains unchanged, you won’t be able to connect with T-Mobile.

Now that you know what could have gone wrong with T-Mobile, let’s check what are the possible ways to resolve the problem easily.

Solution #1 Re-Insert The T-Mobile SIM Card

First, we suggest re-inserting the SIM. One of the most frequent issues that could cause interference with your T-Mobile connection, is a problem with the SIM card or the slot itself.

reinsert t-mobile sim

To reseat the SIM card, please follow the steps down below:

  1. Grab the SIM instrument that was delivered with your phone.
  2. Insert it into the pinhole above the SIM slot until you hear a click.
  3. Take the SIM slot out and detach the SIM card.
  4. Wait for 5 minutes and re-insert the SIM.

Important: The SIM card must be compatible with the slot on your phone.

T-Mobile usually delivers the biggest SIM cards and you have to take certain compartments of the SIM itself in order to become compatible with the slot on your phone.

Once you have reinserted the SIM, check if you would connect with T-Mobile now.

Solution #2 Toggle Airplane Mode OFF

If you’ve enabled the airplane mode, regardless of the type of your device, you have to turn it off in order to receive reception.

While enabled, the airplane will block all signals coming to your phone, including WiFi and cellular.

T-Mobile’s network uses cellular data to connect with your phone, so this means that the airplane mode will actively prevent T-Mobile services from reaching in.

Solution #3 Update The APN

  1. Open the Network settings on your phone.
  2. Head to the Mobile Networks > Access Point Names.
  3. Tap on APN settings and choose IPV4.

You might have to reboot once you’re done with these steps in order for the changes to take effect. When ready, test if the services will not show up, if not proceed further down.

Solution #4 Toggle The Frequencies

It is possible that the frequency you’ve chosen isn’t compatible with your T-Mobile data plan. We suggest switching to 2G, 3G, LTE, and so on.

Test out with each and determine which one will deliver the T-Mobile’s network.

Solution #5 Reset The Network Settings

If the “T-Mobile not registered on network” problem still persists, we suggest resetting the network settings of your phone.

Sometimes a wrong configuration of the settings might prevent you from pairing with T-Mobile’s network, therefore you won’t get any cellular data.
