Will Cel-Fi work with my phone or iPhone?

Your Cel-Fi should work for any 3G capable phone or higher that is normally used with your Operator.  For iPhones and T-Mobile, Cel-Fi model RS2 will work for all iPhone models. 

If your Cel-Fi systems seems to be installed correctly but you are not seeing more bars, please visit here to learn more about how iPhones calculate bars.

iPhones prior to the iPhone 5 are not compatible with RS1, and only iPhone 5 model A1428 with serial numbers ending in FH19, FH1C, FH1D, FH1F, FH1G, FH1H are compatible with RS1.  Tap Settings > General > About to check the serial number.
