How to keep your number

1. Order online

Decide which plan you would like, and during the order process you’ll be asked if you’re switching from another mobile company.

2. Give us your PAC code

You’ll be asked to enter your PAC code. Text PAC to 65075, and you’ll get your PAC code.

3. Put your feet up

We’ll let your old provider know you’re leaving and switch over your number. It might take up to 48 hours.
