I am traveling to Germany this weekend to spend my spring break with a friend who lives there, and fly to and from Frankfurt-Main airport. What I wondered, would it be possible for a cheap phone (Nokia Now think of those tiny block in the early 00s) and a plan for pre-paid dearly for them? In addition, nobody knows what I have to pay the price, and precisely one of locations throughout the airport in question? I could also try the cheapo phone on the way back?
