If you're leaving Zable Mobile and you don't want to keep your number, you'll need a STAC (Service Termination Authorisation Code) to give to your new provider. If you do want to keep your number, you'll need a PAC instead (see the related article).
How to get your STAC:
Text STAC to 75075 from your Zable Mobile number, free of charge.
You'll receive your STAC code by text, usually within a minute.
Give the code to your new provider.
Good to know:
Your STAC is valid for 30 days.
Using your STAC with a new provider will end your Zable Mobile plan.
