Comparison of iPhone plans and rates offered by Sprint, AT&T and Verizon

Personal Hotspot

With the personal hotspot feature, the iPhone can be used as a Wi-Fi base station to connect up to 5 devices to the Internet. Verizon charges $20 a month for this feature and allows 2GB of data use. This fee is in addition to the cost of their data plan. AT&T does not price the mobile hotspot option separately. Their fee is $45 for 4GB of data, which includes data consumed as mobile hotspot or by the phone.

Talk or be online

The two iPhones are designed for different cellular networks - AT&T's is GSM and CDMA for Verizon. A CDMA limitation is that you cannot talk and be online at the same time. That means you can't simultaneously browse or send e-mail when on the phone. The Personal Hotspot feature also cuts off. On a 3G network, incoming calls take priority and interrupt your online connection but in a 2G area, you remain online and the call goes directly to voice mail. Text messaging is not affected by this limitation - you can talk and text at the same time.


Several users and reviewers have panned AT&T for poor coverage and dropped calls. Independent reviewers testing both phones have found Verizon's coverage to be better over all. There is, however, a possibility that with a surge in iPhone users, Verizon's network will experience the same bandwidth constraints that plague AT&T.


Having conducted tests for coverage and speed Wired found that AT&T download rates are 62% faster than Verizon, and AT&T upload rates are 38% faster than Verizon.[4]

4G coverage

As of September 2012, Verizon has 4G coverage in the most number of cities. (see 4G coverage map) However, AT&T supports HSPA+, which is comparable to 4G in terms of speed and is in more cities. iPhone 5 supports HSPA+ and is the first iPhone to do so.

International Use

Globally GSM is a more popular network than CDMA. So chances are higher that your AT&T iPhone will work internationally - 220 countries for AT&T vs. 40 for Verizon.
