Sweet arrangement, but I don't have a bigtalk sim or an android phone. Is it worth it for me to jump through all those hoops just to save a few $$$ and possibly end up with a 'solution' that doesn't work (or doesn't work properly).
If TravelCell, ILwireless or Talk-n-save are all the same, should I specifically prefer any one of them and why?
I know lots of people who use Travelcell. It is the recommended cell provider for many of the American post-high school Yeshiva programs in Israel (my Rav's Yeshiva in Jlem uses it for their talmidim, and he rents from them in the other direction when he comes to the US).
If you don't plan regular trips to Israel (say, once a year or so) probably doesn't pay to jump through all the hoops. If you did, the solution will work just fine. I just bought the GSM Android phone from someone on eBay, and will set it up before I go.
Otherwise, just go with Travelcell or another provider, and all should work just fine.
