Best Bulk Data PAYG SIMs in the UK

I want to buy a big chunk of data and use it until it runs out. I'm not interested in a contract. I don't want a bundle of phone calls, SMS, or ringtones. Just give me DATA that lasts for as long as possible.

Here's the best data deals that I could find. Stick them in your 2nd SIM slot, use them as broadband backup, or shove in a dongle and attach to a Raspberry Pi.

Operator	Cost	Data	Length	£/GB	£/Month	Link
EE	£50	120GB	12 Months	£0.42	£4.17	Amazon
O2	£40	12GB	12 Months	£3.33	£3.33	Amazon
Three	£45	24GB	24 Months	£1.88	£1.88	Amazon
Vodafone	£30	12GB	12 Months	£2.50	£2.50	Amazon
Vodafone	£45	24GB	24 Months	£1.88	£1.88	Amazon
1p Mobile	£30	3GB	12 Months	£10.00	£2.50	1pMobile
Anywhere	£60	0.6GB	12 Months	£20.00	£5.00	Anywhere

If you want the cheapest data - it's got to be EE. Less than a quarter of the price-per-GB than Three.

For the cheapest per-month equivalent - there's nothing between Three or Vodafone. Just pick whoever gives you best coverage.

Worth also checking whether the network you choose supports 5G on their pre-paid SIMS. Same for roaming. Some do, some don't - it's not always clear from their websites.

I'm not sure if I can physically use 120GB in a year given that I'm mostly WFH. So I think I might give Vodafone a go.

If you've spotted any better deals - please let me know in the comments below.
