Data Throttled: Reports indicate that AT&T throttles MVNO data speeds to 500 kb/s in markets where AT&T offers 3G and 1,500 kbs in areas where AT&T offers 4G. It is possible that these reports are incorrect, or that AT&T is throttling data for MVNO customers. Reports on Howard Forums indicates that the throttle can be avoided by using proxy settings. H20ís instructions on configuring data include the use of the proxies that are reported to avoid the throttle.

Note: I do not recommend H2O Wireless. It takes 20-30 minutes to reach customer care. When you finally do reach someone, you may be given incorrect information or be disconnected. The CSRs speak very quickly, and seem to want to get you off the line as quickly as possible. H2O Wireless CSRs have made representations that were not accurate, such as one representative promising that he had added a special code to their system to shorten the future wait time to "no more than 10 minutes."

E-mails are not handled in a timely fashion.

H2O Wireless has been known to play the "reasonable use" game, where they promise unlimited talk or unlimited data, and then terminate service before the end of the monthly period for users who exceed an unstated cap. H2O recently changed their $60 "unlimited" data plan to a 3 gigabyte plan, and then to a 2 gigabyte plan, and now to a 1 gigabyte plan, presumably in response to these kinds of criticisms.

There are many other AT&T MVNOs with better customer service, and so I recommend against H2O Wireless.
