H2O Wireless GSM offers flexible and affordable wireless plans to meet your lifestyle. Whether you are looking for all-you-can-use unlimited plans or simple yet wallet-friendly budget plans, you have come to the right place.
The H2O Wireless SIM card can be used with most AT&T cell phones and any quad-band unlocked GSM phone. Phones must operate on the "850/1900" 3G frequency bands to get 3G high-speed data or faster, otherwise you may only achieve up to 2G speeds. After receiving your SIM card, just go to H2OWirelessNow.com to activate it, then pop it in your phone* and start calling. You can choose from H2O Wireless Pay-As-You-Go and monthly unlimited plans.
*With some higher-end phones, H2O Wireless phone APN settings may be required, and are found at the H2O Wireless website.
