I'm traveling some in Europe next month, and since I'm no longer with Verizon, I finally have the option - I believe - of carrying my phone with me when I travel. But I'm not entirely sure how I go about this most effectively. There are a lot of answers out there (including on this forum), but no where could I find a consise break down of what your options are for voice only, voice and data, and what the differences are between Germany (T-mobile) and France (not T-Mobile). What I was hoping to find answers to are, for people with t-mobile purchased phones, what are our options abroad? From what I've gathered, the standard T-mobile answer is to keep your SIM card in place and roam on t-mobile (in Germany in my case) and have no access outside of t-mobile (again, this would be France for me). And from what I've gathered, the voice is like $1-$2 for this option, and data is either not included or so expensive it's not worth even considering. But what if you're willing to swap out SIM cards? I see info of people who go through hoops to get their phone/service just how they want it in Europe, but they live in those countries. What if I'm only in the country for 6 days? What modifications (if any) make sense for such a short trip? Anyone who knows answers to these questions, and especially has any experience traveling abroad with a G1, your help would be greatly appreciated.
