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

• Select Mobile Data / Connections / Network Settings
• Tap Mobile Networks or Network Mode
• Choose 4G / LTE or LTE only (wording may vary depending on the device)
• After changing this, restart your phone and check if the connection improves.

If the issue continues after completing these steps, it may require further investigation on the network side.
