Program SIM or iPhone to work on 2 networks
Posted on 2011-02-13
I have an iPhone 3Gs and I want to know if there is a way I can access 2 carriers without having to swap SIMs.
My phone isn't locked to a carrier as I can put each SIM in the phone and it works on that network. I have a problem in that one carrier has cheap phone calls, but terrible data access and the other one is expensive on the calls, but the data access is great.
Is there some way I can get one SIM programmed (or the phone) to use one carrier for phone calls the the other carrier for data acces?
