9. How’s the T-Mobile and AT&T coverage?

T-Mobile’s coverage is within 1% of Verizon and AT&Ts. There are some areas, generally outside of urban/suburban areas where coverage is weaker. However, T-Mobile can also supply a home box that enhances coverage. Also, T-Mobile is aggressively increasing their coverage in weaker areas during this year and is expecting to have as good or better coverage than any carrier. You can check Coverage here:



AT&T Domestic Wireless Data Coverage. This map shows an approximation of wireless data coverage in the United States, Puerto Rico, and the U.S.Virgin Islands.



10. Coverage inside my home isn’t great. Is there anything that can be done?

Yes, T-Mobile can provide a device to boost signal for your mobile number. If you cancel service, the device will need to be returned (otherwise there will be a $500 charge). A $25 deposit is required for this device.
