Verizon iPhone to Debut With Unlimited Data Plan

When the iPhone finally arrives on Verizon’s network, how will the carrier set it apart from the one that’s been offered by AT&T since it first debuted in 2007?

Here’s one way: By offering it with a wireless service plan free of the data caps used by AT&T.

Sources close to Verizon tell me the carrier will offer the iPhone with an unlimited data plan (presumably the same $30 unlimited plan it offers for other smartphones)–though they wouldn’t say for how long. That should distinguish it a bit more from the iPhone on AT&T, which requires a capped plan for data service.

Not that such differences worry AT&T any. “We think customers will prefer AT&T’s faster speeds and better functionality over a CDMA network device,” a spokesperson told me. And he has a point. AT&T’s UMTS network allows the use of data and voice simultaneously. Verizon’s CMDA network doesn’t–at least not yet. So, initially, Verizon iPhone users won’t be able to use the Web or check email while on a call–something AT&T iPhone users have long been able to do.

All Things D reported Friday that the special event Verizon is holding in New York Tuesday will be the carrier’s long-rumored iPhone announcement.
