How do I cancel AT&T?

[MacMonkey13]

My contract with ATT is up tomorrow. Do I need to call or will activating my new iPhone with Verizon automatically cancel it?

Once you port you number to Verizon your contract with AT&T is automatically terminated, just make sure you are defiantly out of contract or you'll get hit with and ETF.

definitely check when your next billing stars otherwise they might charge you for the whole month even if you only used a couple days into the new month.

Yea make sure you are 100% past your contract date. I made the mistake on my Tmobile account of going by their upgrade date.

Cost me $150, so yes call and make sure.
