No action required until the port-in is successful.
The port-in request will be processed once you received Grid Mobile’s SIM card. You should only switch to Grid Mobile’s SIM card upon successful port-in. You will be notified once the port-in is completed. Another way to know whether the port-in has completed is when the service from your previous service provider is no longer available.
After changing to Grid Mobile’s SIM card, a reboot may be needed for some handsets.
