Sky's best SIM only deals

Out of the best SIM only plans on Sky Mobile this September, we think the leading deal is their 12‑month 6GB for £8 one below, which also comes with unlimited minutes and texts:

It isn't actually the cheapest 6GB data or more SIM available overall this month but if you definitely need your plan to use the O2 network, it is the lowest cost option. See the networks with cheaper plans here:

Their 20GB for £12 SIM is another good option

For those needing more data, another option for you on Sky, is their 12‑month SIM below, which costs £12 a month for 20GB data and comes with unlimited minutes and texts:

You have got other cheaper options if you don't need your SIM to be on a provider that uses the O2 network. But if you do, it is the cheapest current deal available. Here's which other networks can beat it:

Sky's 3GB for £6 plan is a good option too

Their £10 for 10GB plan is a decent deal for September

To get a bigger chunk of data, we think this 10GB is one of the best SIM only plans on Sky Mobile too. It's on a 12‑month deal, comes with unlimited minutes and texts - all for £10 a month:

It's a good deal by Sky's standards but price-wise you can still beat this plan on other providers (even ones that still use the O2 network). Here are the networks offering it cheaper:
