It's customizable but barely
It's customizable, barely but more so than others. But mann idk why US carrier are like this, very cheapskate on data. 6gb/month is so 2010. In other countries mainly Asia, we paid 20-30/months for 100+GB and some even unlimited (but limit per FUP). The only reason I went with Mint was due to cheaper package, as a non-US resident. I'm not gonna commit to a postpaid plan.
