If you would like to bring your h2o wireless number over to Ultra, there are a few things you need to do before you activate your Ultra Mobile account. 

Don’t cancel your h2o Wireless service yet

If you cancel your h2o Wireless account before transferring your number to Ultra, the number will be lost.  

Gather essential account details

To bring your number to Ultra, you’ll need your h2o Wireless Account Number, Account PIN or Number Transfer PIN and billing ZIP Code.

Have h2o Wireless release your number

Contact h2o Wireless’ customer support (1-800-643-4926) and ask them to release your number and provide your “port out” account number.

Some users report the account number is not the same as their phone number (it may be an 8-digit code).

Get your h2o Wireless account PIN Number

While on the phone with their customer support, h2o may require you to provide 3 most recent outgoing calls (or another form of validation) before giving you your PIN.
