| T-Mobile | 1900 Dodge Rd NE | I have no T-mobile coverage anywhere in Cedar Rapids.  Phone (a T-Mobile 768 flip phone) says iWireless network.  The phone battery dies within 4-6 hours, as if it is straining for a signal.  The battery lasts 2-3 days when I'm in other cities.  In Cedar Rapids I can make outgoing calls, but half the time people try to call me the call is sent straight to voicemail.  When I receive texts the phone warns me that I'll have to pay international data roaming fee.  Even when I agree to the fee, the text does not download correctly.  Phone is basically useless in Cedar Rapids except for outgoing calls.  Phone works great outside of Iowa. | 2015 |
