iD Mobile deals have a reputation for delivering reams of data for a rock-bottom price, but this is something special: unlimited 5G data for an eye-boggling £11.50/mth on a one-year contract via Mobiles.co.uk. That’s the cheapest unlimited data SIM plan on the market, leaving all of the competition in its wake.
For example, you’d pay £18/mth for 12 months of unlimited data from iD Mobile directly, £22/mth from Three, £35/mth from Vodafone and £37/mth from EE. You’re not compromising on quality, either: Three, iD Mobile’s host network, now has the country’s widest and fastest 5G network, according to Opensignal.
The only thing you need to do is claim the savings via cashback, but the process is straightforward – Mobiles.co.uk has even produced a video that guides you through it. As always, make sure you get in there quickly because bargains this barnstorming don’t last for long.

So why should you go for iD Mobile? In our most recent review of its service, we gave it four stars out of five, highlighting its incredibly low prices, 5G performance and range of long or short-term plans. It registered fewer complaints to Ofcom than bigger rivals such as Three, Virgin and Vodafone too.
And, if you’re after a longer contract, Mobiles.co.uk has you covered: you can pick up 100GB for £13/mth, 200GB for just £2/mth more at £15/mth and unlimited data for £16 /mth on a two-year plan. Those are extraordinarily good value, especially given that any unused data will roll over to the next month.

We’d still opt for the one-year iD Mobile deal, though, because you simply can’t do anything better for the price. Once again, sign up as soon as possible because it won’t be around forever.
