I do always forget other prepaid services.
Haven't looked into Cricket in a very long time. I'm assuming they still throttle LTE speeds, which I'm not a fan of. Also sucks that you can't tether on unlimited plans (I need tethering ability).
If you only need a single line AT&T's newer GoPhone plans are pretty attractive. $45 ($40 with autopay) for 6gb data, includes tethering, calls to and from Mexico and Canada, and doesn't throttle like Cricket. GoPhone's unlimited plan at $65/month is worse than Cricket's though because AT&T decided to throttle speeds at 3mb/s (versus Cricket's 8mb/s).
