So theres a sprint tower on my campus, therfore, i always have awsome service:browani:, even in basements. Today I was on the phone and my call dropped. I was like wtf, that never happens. I looked at my phone and i had 1bar and then it went up to about 3 (i usually always have 5). So i'm assuming the tower spontaneously combusted and I lost service until my phone decided to connect to a different tower, further away. Also I suddenly had no service in the basement where I normally have 3 or 4 bars while nobody else with other providers ever has service. Now everything seems to be back to normal, but does what the hell happened?
