There's not really much you can do besides installing an expensive cell signal repeater inside of a building. If the building is blocking the signal it more than likely has something to do with the materials that the building is made out of. Verizon uses CDMA technology where T-mobile uses GSM. The difference in technology and wavelength may make the difference in reception inside buildings.

Yes. It is fine outside the building. Constant 4G - although the signal strength fluctuates.

Does your signal improve when you go outside of said buildings? E = Edge which is just a slower data connection.

I have joined T-Mobile - moved over from Verizon about a month ago. I am using an Iphone 5S. I am getting a load of E network connections and No Service connections. Always inside buildings - so I'm thinking that that is where the problem lies.

Does anyone know if there is any way around this low signal strength issue?
