No one enjoys sending hundreds of texts to tell their contacts they’ve got a new number, so it’s SMARTY to bring your old number with you.

Simply order your SIM & request a PAC code from your current network. Once you’ve got your code. Log into your SMARTY dashboard and follow the easy steps.

Our SIM breaks down into these 3 sizes:


Credit back for unused data

At the end of the month, we’ll give you money off data you haven’t used, all the way down to the last MB.
