You don't have to pay anything to Public Mobile for a transfer (port) or a new number. However, your previous wireless provider may charge you a fee for a couple different reasons.
1. You have an un-paid balance of a device.
2. You were on contract and you are breaking the contract to move to Public Mobile.
3. You ceased the contract part way through your billing cycle.
There may be more but it's all I can think of for now.
Nothing to public mobile. You can change your number free of charge once every 30 days. You can port in or pick new one
I am new to PM. I saw this reply.
every 30 days means literary every 30 days or each calendar month?
Nothing is ever by the month at Public Mobile except for maybe the calculation of community rewards. 30 days means litteraly 30 days.
