We’ve kept things really simple with the SMARTY plans, but we realise that from time to time, you may need extra data or the ability to make chargeable calls.

That’s why you can also get data add-ons and out of plan add-ons whenever you like.

Please note that you'll only be able to use an add-on when you have an active plan. If you haven't renewed your plan, you won't be able to use any of our services, including any available add-ons.

Data add-ons

If you need more data during the month but you're happy with your SMARTY plan, a quick top-up might be the answer. Our add-ons never expire, and only costs £1.00 per GB! We have 3 data add-ons to choose from:

  • 1GB

  • 2GB

  • 3GB

Out of plan add-ons (previously cash add-ons)

All the SMARTY plans come with unlimited UK calls and texts, but if you need to make a chargeable call (such as calling a service number that starts with 084 or 087), an international call, or use your services abroad outside of the EU, you'll have to add money to your SMARTY account beforehand.

We have 3 Out of plan add-ons available: £5, £10 and £15. Out of plan add-ons also never expire, so you can keep them on your account ready to use for a chargeable service, or convert any leftover Out of plan add-on into money off your next bill!
