Can I get a SMARTY SIM with bad credit?
Yes. We believe anyone should be entitled to mobile with no credit check. Because you pay upfront, we don’t need to know your credit history. And unlike the usual contract SIM deals for bad credit, we don’t tie you in or overcharge you for extra data.
Unlimited UK standard calls and texts
A bad credit rating shouldn’t hold you back. With SMARTY, you can enjoy the best bits of a pay-monthly plan and call your friends and family as much as you want.
Get money off data you don’t use
With SMARTY, you get credit for any data you don’t use in your data discount plan. We believe this makes us one of the fairest deals around for SIM-only contracts. How does it work?
£5 is the base monthly rate included in the price for all data discount plans, offering unlimited standard UK texts and calls. The rest is for data.
At the end of each month, we take any unused data you have and discount your next month’s plan - at the standard rate of £1.25 per GB, the same price it’s charged at.
For example, if you’ve got 3GB of unused data, you’ll get £3.75 off your next month’s plan. We even calculate using remaining MBs, not GBs.
This means you only ever pay for what you need.
Extra data at fair prices
Add-ons that don’t cost the earth
You never know how much data you’re going to need. If you run out of data during the month, extra data will cost just £1.25 per GB.
Our data add-ons never expire, as long as you have a live, current SIM-only plan.
The flexibility of pay as you go. The benefits of a monthly contract.
Because your SIM is paid for in advance, you can enjoy your data allowance without worrying about an unexpected bill – just like regular contract deals.
But you also have the same peace of mind you get with pay as you go – no minimum term contract, the freedom to cancel at any time, and the flexibility to add more data whenever you need it.

SMARTY connects to 4G network wherever it can. SMARTY is not compatible with 2G handsets.
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.
