While we are waiting for your carrier to release your number, your old service continues to work with no interruption. It will continue to work until the moment you receive an in-app notification and email that your CPFS Mobile activation was successful. Once you’re alerted that your activation was successful, your old carrier SIM will no longer work.
We do ask that you remain on Wi-Fi during activation so you receive notifications alerting you when your activation is complete. Once you receive confirmation, you can insert your CPFS Mobile SIM card.
In case you’re interested in the details:
When you input your current carrier’s account number, transfer PIN, and billing ZIP code into the app, we send a request to your carrier asking them to release your number to us. This is the part that can take about 2-4 hours (and in some exceptional cases we have seen this take a few days with landlines, but this is not common).
