AT&T Wireless has added new wireless plans for the iPhone aimed at business customers.

The new rate plans require a 2-year service agreement or a renewed 2-year service agreement. AT&T offers three Enterprise Data Plans for the iPhone ranging from $45 to $65, with the main difference being amount of SMS messages included.

Considering these plans are for business use, AT&T kindly offers these iPhone International traveling tips. Although not among their recommendations, you should remove your SIM card while traveling outside of AT&T's calling area. This will still enable you to use WiFi on your iPhone and prevent any accidental data connections or calls.
