What is the best way to use a phone in Germany? Is there a German GiffGaff?
If I were to move to Germany, which would be the best and cheapest way for me to use my old iPhone? Are there pay-as-you-go networks with Internet included like GiffGaff in the UK? I will probably have to continue paying my current phone contract so a cheap additional one I could get with a German SIM would be great.
