Learn how to troubleshoot problems with SIM card exhaustion. T-Mobile customers with older SIM cards (from 2010 and earlier) may have registration problems due to SIM card exhaustion. Older SIM cards have a limit on the amount of times a SIM card can register on the network. Once the limited has been reached, the SIM card can no longer register on our network.
You may notice the following symptoms:
- Device cannot register to T-Mobile network at anytime and at any location.
- When performing a network selection, the device finds the T-Mobile network, but cannot connect.
Important: If the device does not find any networks, it is not SIM card exhaustion.
- Device will display the following errors when trying to connect to the network:
- 'Network Not Allowed'
- 'Network Not Found'
- 'Your SIM Card does not allow connection'
