1) Check you’re eligible to switch from SMARTY
If you’re out of contract with SMARTY, you can switch network any time you like and it won’t cost you a thing.
To find out if you’re out of contract, you’ll need to head to the SMARTY site and log in to your account.
Just log in, click on the menu icon, select 'Account settings' and the rest is easy.
And if you’re interested in switching but want a bit more information first, text INFO to 85075.
2) Contact SMARTY to tell them you want to leave and get your PAC code
Your next job is to contact SMARTY to tell them you’d like to leave. To do this, just text PAC to 65075 to get your PAC code. It’s this short, alphanumeric code that will enable you to transfer your existing phone number to the network you want to join.
SMARTY doesn’t have a customer service telephone number to call. But if you prefer, you can get in touch by email to request your PAC code via its website.
Once you’re logged in, click on the menu icon. Then choose Account Settings and go from there.
SMARTY will then send your PAC code to you by email. By law, networks have to provide you with your PAC code within two hours of you asking for it. So you won't have long to wait.
