Is it possible to be able to use a Huawei EC 168 C with Tata, Reliance, BSNL & US Carrier. I believe Tata, Reliance & Alltell / Verizon (US) currently or in the past have used the Huawei EC 168 EVDO USB Data Card. I do not want to have to buy 3 cards from each when the hardware is the same. Is this something I can do easily with Software / Dialer / Simple Config file or do I have to do a Hack / Flash / ESN etc change? What are the possibilities?
