We’ve got a trip to the USA planned and coming up soon. My somewhat nifty smartphone offers one feature most others don’t: dual SIM cards (one for work, one for personal use).
I’d like pre-paid flat rate GSM service for about 10 days in June in a densely populated urban area in the middle of the USA. It would be nice if that option included the possibility to retain unused credits and a phone number for use months later when visiting other parts of the country.
I’ll do my own homework too, of course, but I figure plenty of tech savvy expatriate continent-hoppers must have already found the optimum solution.
I seem to recall that AT&T and T-Mobile USA are the only big-name GSM operators in the USA. Is that still true?
What are my options here? What (and when) did you try that worked / didn’t work for you on a trip back to the USA with a German-issued smartphone? (Other than disconnecting my life from the internet, of course…)
