Looking at what you can get on SIM only with Mozillion this September, our best-rated deal would be their discounted 1‑month plan below, which comes with 80GB data, plus unlimited minutes and texts for £11 a month:
It's definitely one of Mozillion's best. But it's not market-leading. You can get a similar plan on other providers for less, even if you need your SIM to use the EE network. Here's where else you can get a lower price:
We also like their £9 for 30GB plan

For a smaller amount of data, we also think this discounted £9 Mozillion SIM is one of their best options. It comes with 30GB data, unlimited minutes and texts on a 1‑month deal:
Even though it's in our pick of Mozillion's best SIM only deals, you can actually beat it on price with other providers, including ones that also use the EE network. See who's offering it for less here:
Their 3GB for £6 SIM is another good option

If you don't want so much data, Mozillion's discounted £6 SIM below is another of their best deals this month. For £6 a month, it offers 3GB data, unlimited minutes and texts on a 1‑month plan:
While this is a good enough deal to make it into the best of Mozillion's SIMs, you can beat it for price (even if you definitely want a provider that uses the EE network). Here's where you can beat it on other networks:
