8GB, commitment-free SIM plan

How it works


Pick a plan

Activate your SIM

Your plan allowance doesn’t start until you’ve activated your SIM. Simply activate via the dashboard & start making SMARTY savings.



You’re now free to chat, text and tether without worrying about going over your limit. If you don’t use your data, we’ll give you money off next month.

Incredible coverage

SMARTY is powered by the expansive Three mobile network. With our network covering 98.6% of the population (indoor) and 99.5% (outdoor), you’re likely to be one of them.

Keep your number

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.

Your base plan costs £5 and data is £1.25 per GB on top.

No need to change your number

As soon as your SIM is activated you can port your number to SMARTY. You’ll just need a PAC code from your current network.


Adding data or credit

If you run out of data it’s £1.25 per GB - the same as it costs in your plan. To call an 084 or 087 number you can add credit in £5 increments. Add-ons never expire.
