    An unlocked GSM phone can be used on any GSM network (Cingular and T-Mobile). However you can only use Verizon branded phones on the Verizon network and Sprint phones o the Sprint network as they use the CDMA technologies and have strict policies on who they allow on their networks. Unlocked GSM phones can also be used in other countries, particularly in Europe. As for the Far East, it is really a hodge-podge of technologies. Basically a Japanese phone wil only work in Japan. I think Korea has a GSM network. Australia has GSM as well, I think.

    You can view GSM carriers here... www.gsmworld.com

    What is your goal, is it to unlock your 7100i, if so then as mentioned above you cant, BUT, you can however unlock it to use on Boost Mobile or even Telus, which are also iDEN providers.

    Any other questions please ask.

    Nextel devices are not GSM. They are iDen. That's why the SIM won't work.
