I opted for T-Mobile over my previous cell phone company due to a special they had for UNLIMITED everything ( Minutes, Data etc.) . For a couple of months T-Mobile was great with no issues whatsoever however in the past 2 months their signal/service has been terrible. I've worked in the same office for over 5 years now and all of my previous carriers have worked great including T-Mobile but in the last 2 months I get ZERO signal. I don't get 1 bar, I don't get LTE, 3G, or 2G.
What I get is No Network Connection No signal found for mobile networks. Now I've tried everything, restarting phone, changing the settings etc. and nothing works.
