Price Plans and ways to pay
We offer a SIM-only, pay upfront deal. So there’s no minimum contract and no monthly bills to worry about.
There are three plans to choose from (Small, Medium and Large) and you can switch between these monthly.
All plans include unlimited calls and texts. Unlimited calls include: standard UK landlines (starting 01, 02 and 03),
freephone numbers (starting 080) and standard UK Mobiles (starting 07).
Each plan lasts a calendar month. If you don’t use all of your data within this time we’ll provide you with
an automatic discount against your next plan, based on what you haven’t used (minus a basic charge of £5).
The table below shows you how we work this out and for more information, take a look at


Discount per
unused GB
Small 2GB £7.50 £5.00 £2.50 £1.25
Medium 4GB £10.00 £5.00 £5.00 £1.25
Large 8GB £15.00 £5.00 £10.00 £1.25

If you run out of data you can buy an add-on – this won’t expire until you have used all of the data.
For calls that aren’t included in your plan you can buy a cash add-on. This also won’t expire until you’ve used it all. The type of
calls you can make with this credit are numbers starting with 084 or 087 and non-emergency numbers, like 101. There are some
services that are not available with SimplifiSim at the moment. These are international numbers, roaming abroad and premium
numbers (starting with 09).
