US Cellular, or I wireless? I want a sidekick 3, but Tmobile doesn't work where I live, so can I use an unlocked one with Verizon, US Cellular, or I-Wireless?

no, not with verizon or US cellular, because thy use a different network that doesnt work with tmobile phones. it MIGHT work with cingulargood luck

You cant use it with Verizon, only for GSM phone companies. Check if you have cingular in your area if so you can use them.Im not sure if US cellular is GSM (gprs is the technology) but just call and ask if they are a GSM network, if so you can use your sidekick

The sidekick will only work for T-Mobile, due to the fact that it has to connect with Danger's servers in order for all of its functions to work properly. US Cellular is CDMA, so it certainly won't work with them.

I'm not sure if the Sidekick will work when a T-Mobile user is roaming.
