So I'm going to be in Germany for "training" in a couple weeks and wonder if anyone can suggest some kind of temporary cell service I can buy. We'll actually be landing in Amsterdam and spending a day there before taking a train to Bochum if that makes a difference. I've got a Nexus 5 which should cover at least some major networks but I can work out the details myself once I've got an idea. Basically I'm thinking if I can just buy a sim card there with some kind of low-cost daily plan (T-Mobile has an unlimited $3 a day plan in the USA, for example) that'd be swell. Any suggestions on a carrier to try and where I might be able to buy a sim card?
