If you're looking to switch from your current provider to a better one, go with Mint. Plans start at just $15/mo, and include high speed data, plus unlimited talk and text. Way better than AT&T/other unnecessarily expensive plans. I made the switch last year and saved a ton of money. Good coverage. Use my referral link above for $15 added as starting credit.
