Earlier quoted context omitted.
T-Mobile has a 5GB (LTE) + unlimited (slowed after 5GB) plan for $30/month. It only has 100 minutes, but you can use Google Voice or similar over data. And who talks on the phone anymore anyway?
The reason I mentioned Straight Talk was that it works with all 4 main US carriers. T-Mobile doesn't have service everywhere. >And who talks on the phone anymore anyway? I know a number of people who wouldn't buy a plan unless it had unlimited minutes. Some people use their phones for talking heavily.
I do talk on the phone all the time at work, but for personal use it's pretty minimal. But even if I did, the Hangouts Dialer app will make GV calls over data, so I don't use any minutes, and I don't even use data when I'm on wifi.
