This is a great £10 per month deal for 30GB data, which for most people is plenty of data – saving you money and giving you plenty of scrolling capability.

This is a perfect option for those of you that don’t need a huge data plan but want to be sure you can scroll and stream till the end of the month.
You’ll get 30GB at a reduced cost of £7 per month for the first 6 months of the plan, and unlimited minutes and texts.
30GB data | Unlimited calls and minutes | £7 (6 months half price) | 24 months – buy from Three
8. 12GB data: £7.33 per month (after £20 cashback)
This is the goldilocks of SIM-only deals, not too much or too little data for a reasonable price of £9 per month (or £7.33 after cashback).
For people who aren’t big data users but need more than small 1GB or 2GB options, this affordable 12 month plan might be just right.
- 12GB data | Unlimited calls and minutes | £7.33 (after cashback) | 12 months – buy from Fonehouse
9. 8GB data: £7 per month (after £24 cashback)
If your data needs are minimal then take this SIM-only deal into consideration, you can grab 1GB or 2GB SIMs but you might end up paying more.
Yes, 8GB isn’t much for most people, but if that’s enough for you we sure you’ll like that super-low monthly cost of £7 or £8 before cashback.

It is great for anyone that doesn’t eat up there data and just needs enough to see them through the month. It comes in at just £5 for the first 6 months.
- 8GB data | Unlimited calls and minutes | £5 (6 months half price) | 24 months – buy from Three
What is the best Three SIM-only deal?
Our favourite SIM-only deal from Three right now is without a doubt the unlimited data with first six months half-price (£11) plan.
It’s perfect for data-hungry phone users who are into gaming or like streaming content on the go.
We also like the unlimited plan from Buymobiles as this gives a shorter contract for just £16 per month, which could save you money in the long run.
If you like to stick with your contracts for longer, a 12 month option might not be for you as there is no guarantee you can renew it for such a low price.
How long is a SIM-only contract with Three?
Directly from Three there are, well, three different contract durations for SIM plans.
Depending on your choice, you can either sign up to a 1-month, 12-month or 24-month package.
Keep in mind though: the shorter the contract, the more you can expect to pay.
So while a 24-month 30GB plan costs £14 a month, the equivalent month-long plan costs £24 a month.
That’s quite the increase, but is hardly a surprise: Three simply wants your business for as long as possible.
Other third party providers often do 12 or 24 month contracts – omitting the one month option.
Why choose a SIM-only deal?
SIM-only plans are a great choice if you’ve already got a phone that’s been paid for.
Without that expenditure to factor in, you can easily keep your phone outgoings relatively low each month with a SIM-only plan.
You won’t necessarily need to commit long-term: most providers offer pay-as-you go SIM plans which you can use on a rolling basis.
So if you’re waiting for the release of the next big flagship phone, a SIM-only plan is a great temporary option.
