Best practice international GSM setup

hwa · 15-01-2014, 19:03

I have and plan to use an iPhone4. Although it doesn't seem to support seamless callback all providers give you the USSD to use to make a call. It's a pain but something I can live with. Maybe there's an APP that will take a number from my phonebook and prepend and append the necessary strings to the number to be dialed. I know there are options to make an iPhone take a dual sim but that's too much for my use case.
