Porting a number away from EasyGo is the same as H2O. You need to call customer service and ask them to release your number for porting. Ask them to tell you your account # and PIN. EasyGo will ask you to provide the 3 most recent outgoing calls to verify that it’s actually your number.

You will need your account number and PIN to port your number away from MobileNation. You will also need the name on the account, address, and the last 4-digits of your SSN.
