[For Selected Customers] Updating SIM Card Network Settings for Plan Upgrade / Network Migration

Updating your SIM Card Network Profile

Your existing mobile number needs to be migrated and ported to our new network before your plan upgrade can be completed. 

Similar to the number porting process when you port your number to a new mobile service provider, this network migration process will cause a brief interruption to your service but it will resume normally once the update is completed.

To make sure you stay informed, you’ll receive SMS updates at each stage of the number porting and plan upgrade process.

If you currently have a "No Service" error on your SIM card, please perform the following steps to update its profile:

Note: Wait a moment after making a change to your network settings. Changing it repeatedly and quickly (i.e. spamming it) may cause an error.
