O2's best SIM only deals
The best value SIM only deal on O2 this month
Out of all the SIM only plans available this July on O2, we'd say their best value deal is their 24‑month SIM below, which gets you 60GB data, plus unlimited minutes and texts for £18 a month:
Even though it's in our pick of O2's best SIM only deals, you can actually beat it on price with other providers, including ones that also use the O2 network. See lower-priced networks' deals here:
£25 for 250GB is O2's next best SIM deal in July
For more monthly data, have a look at O2's 250GB SIM below at £25 a month, as it's another good deal. It's on a 24‑month plan and comes with 250GB data, unlimited minutes and texts:
Unlimited minutes + Unlimited texts + 250GB data (5G) = £25 a month (24‑month contract)

While this is a good enough deal to make it into the best of O2's SIMs, you can beat it for price (even if you definitely want a provider that uses the O2 network). Here are other networks you can beat it on:
There's also a nice 150GB for £22 plan with them this month
For a smaller amount of data, another option for you on O2, is their 24‑month SIM below, which costs £22 a month for 150GB data and comes with unlimited minutes and texts:
Unlimited minutes + Unlimited texts + 150GB data (5G) = £22 a month (24‑month contract)

It's a good enough deal to get into O2's best SIMs but you can actually get a lower price for a similar plan elsewhere, even if you definitely want it to use the O2 network. See the networks with cheaper plans here:
Or their £30 for unlimited data SIM plan is worth a look too
For people who need even more data, O2 have got a £30 deal on SIM only we think's worth looking at. It gets you unlimited data, unlimited minutes and texts and it's a 24‑month plan:
In comparison to the rest of O2's current SIM only plans, it's one of the best. But it is beatable on price, even if you're set on joining a provider that uses the O2 network. Here's which other networks can beat it:
