The freedom of pay as you go. The benefits of a 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: there’s no credit check, no minimum-term contract, the freedom to cancel at any time, and the flexibility to add more data whenever you need it.
Pay for the data you use, not the data you don’t
With SMARTY's data discount plans, any unused data gets discounted off your next month. We think this makes SMARTY one of the best SIM-only deals around.
£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 per GB, the same price it’s charged at.
For example, if you’ve got 3GB of unused data, you’ll get £3 off your next month’s plan. We even calculate using remaining MBs, not GBs.
This means you only ever pay for what you need.
Data add-ons that make sense.
If you run out of data during the month, an add-on will cost just £1 per GB. This is the same amount you pay for data in your usual plan, so you’re not getting stung for buying additional data when you really need it.
Our add-ons also never expire - as long as you have a live pay-monthly SIM, your data is there for you to use. Nice.
Unlimited UK standard calls and texts. Always.
Call your friends and family as much as you want.
Comes with all plans. No catch.
Also works with tablets, dongles and more.
Our SIMs also work with tablets and mobile broadband devices like dongles and WiFi routers. Simply choose your plan, pop your SMARTY SIM in, and you’re good to go.
SMARTY connects to 4G and 3G network wherever it can. SMARTY is not compatible with 2G handsets.
Simply contact your previous network provider or text 'PAC' to 65075 to get a code valid for 30 days. This won’t disrupt your service. We’ll walk you through steps to enter this code to transfer the phone number you want to keep.
If you run out of data, data add-ons are £1 per GB - the same as it costs on our Data discount plans. To call an 084 or 087 number you can add an “Out of plan” add-on in £5 increments. Add-ons don’t expire.
No. Only Data Discount plans get money back for unused data. Look for the “Money back” icon on Data Discount plans.

You can now use SMARTY to make calls to other countries from the UK. International calls and texts are taken from your “Out of plan” add-ons.
You can now use your SMARTY plan abroad. In the EU it works like normal up to 20GB. Outside the EU, or to call internationally, you need to add an “Out of plan” add-on.
When you refer friends to SMARTY, you and your friend can each get a free month. After signing up and activating your plan, refer as many friends as you like by sharing your unique referral link - you'll find this in your dashboard. Once they’ve been active for 14 days, you’ll both get email notifications to let you know you have a free month ready to go.
