Well as far as I have read, most modern phones can accomodate two physical SIM's in one phone using a device known as a dual SIM holder. Any other method i.e. flashing or whatever is something that I know little about. Diciple pointed out to me a thread on this very forum where these devices were discussed and at the time, JK entertainment had them for sale, but the have since backed out of the cell phone business so now i'm left wondering if these things have completely dried up. I could simply buy a cheap phone, but I hate the idea of having to keep track of an extra phone all day.
