Hi



i know it's not really the best forum to ask this question, and the answer is probably no, but...



Let's say i have regular gsm phone service with one carrier, and GPRS over gsm access with another.



Are there some sorts of programable SIM cards which will allow me to access both networks, without changing SIM cards?



Maybe one of you geeks know





Thanks guys
