I have T-Mobile, 3 lines, unlimited talk, text and data. First line is $50, second is $30, and each additional line after that is $10. We were getting capped at 500MB of 4G data per line, but I noticed the other day they raised it to 1GB per line at 4G speeds, then throttled. I never exceed my limit. My 13 year old son is the only one in the family who does, because he's constantly streaming music and videos when he's away from wi-fi he could piggy back off of.
As far as spotty reception, I rarely have a problem, and I read recently that t-mobile is upgrading their coverage.
