How it works
Pick a plan
Choose a SIM only plan & pay monthly for your data, calls and texts. Your free SIM will be delivered to you in just 2 business days.
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.
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:
All the data you need for less

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 a cash add-on in £5 increments. Add-ons don’t expire.
No. You can tether and hot-spot all of your data with no speed caps but you must be in the UK.
No. Only Data Discount plans get money back for unused data. Look for the “Money back” icon on Data Discount plans.
The SMARTY team are available to chat online 8am to 8pm, 7 days a week (excluding Christmas and New Year’s Day Bank Holidays). To contact us click the little green icon in the bottom-right to start or go to the contact us page for further information.
You can now use SMARTY to make calls to other countries from the UK. International calls and texts are taken from your cash 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 a cash 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.
Everything you need to know about our: prices, discounts, offers and add-ons if you’re a customer of ours.
