Hi @Mainy1690,

I'm really sorry to hear you're experiencing issues with your SIM. Please try the steps below, depending on the type of phone you have:

For Android:

Open Settings
Tap General Management
Tap Reset
Select Reset network settings

For iPhone:

Go to Settings
Tap Phone
Tap My Number
Delete the old number
Enter the new number
Tap Save

Then follow these steps to refresh iMessage:

Go to Settings
Tap Messages
Turn iMessage OFF
Go to Settings > General
Tap Reset
Choose Reset Network Settings
Once your iPhone restarts, go back to Settings
Tap Messages
Turn iMessage ON again

Your iPhone should now recognise the new SIM and verify your number.

Regards,

Hi @Mainy1690,

Thank you for the update, and I’m sorry to hear the issue has returned.

As the replacement SIM initially worked and has now stopped, this may indicate a network or provisioning issue rather than a fault with the SIM itself.

To help rule out common causes, please try the following steps:

Turn your phone off completely
Remove the SIM card and gently clean it with a dry, lint-free cloth
Reinsert the SIM securely and power the device back on
Toggle Airplane Mode on and off to refresh the connection
Try manually selecting a network in your phone settings

Try the SIM in another handset:
If possible, insert your SIM into a different unlocked phone. If the SIM works in another device, this would indicate a potential issue with your handset rather than the SIM or network.

Set your phone to 4G/LTE only:
Switching to 4G can sometimes improve stability, especially if 5G coverage is limited in your area.

On most devices, go to Settings
