iD Mobile’s 99GB SIM only deal (£4.50 then £9): how to get it

iD Mobile have just released a Black Friday SIM only deal that will likely end up making the headlines and breaking the internet. You can now get a huge 99GB of data from as little as £4.50 in your first 3 months:

Unlimited minutes + Unlimited texts +  99GB data (5G) = £9 £4.50 a month for 3 months, then £9 (12‑month contract)

🛈 No annual price rises

It’s an exclusive offer held back for comparison websites like SIM Sherpa. Your first 3 months will be charged at just £4.50 a month, followed by a still-cheap £9 a month for the remaining 9 months of your 12-month deal.

Over your contract, that works out to a market-leading £7.87 a month. And the full £9 is still cheap anyway. This is isn’t the type of deal where you get ripped off at the end. Plus there are no price rises on iD’s SIMs.

The main appeal of iD’s 99GB deal might be the low prices but you do actually get some nice extra benefits on iD Mobile that add more value to your deal.

For starters you can use 30GB per month of your 99GB while roaming in the EU at no extra cost. That’s way above average for low-cost mobile operators. And should tide you over for a couple of weeks easily.

We also like their data rollover benefit. If you don’t get through your whole 99GB, anything you don’t use can be used next month. So if you then have a heavy month and go over 99GB, you won’t face charges.

And lastly, iD now have a new loyalty perks scheme. This works a bit like O2 Priority and gives you discounts at online and high street retailers, as thank you for staying with iD Mobile for 12 months.

With an absolutely massive amount of data (9x what the average UK user gets through), this deal is definitely meant for people who use their phones a lot. And for that you’ll want a decent 5G network.

iD Mobile uses Three, which regularly wins awards for having the fastest 5G in the country. Their 4G is good too. And their coverage has improved massively over the last few years. iD have long had WiFi calling as well.

And you can even join iD on an eSIM, meaning you can get up and running in minutes with your new 99GB deal. The main downsides of iD are their online-only customer service, which isn’t great.
