iD Mobile review: the short version
This iD Mobile review sticks to what iD publishes and what Ofcom’s complaints figures show, so you can judge it on facts rather than adverts. iD Mobile is the mobile network brought to you by Currys, and it says it has over 2.5 million subscribers. It sells phones on contract, SIM only plans and pay as you go.
The reason people go looking for an iD Mobile review is usually simple. The deal looked good, the brand is familiar from the high street, and the question is whether there is a catch. Mostly, the catches are the ones every network has. The costly bit is usually doing nothing and leaving a plan in place long after it stopped suiting you.
Everything below was read on iD Mobile’s own pages and on Ofcom’s site on 10 November 2026. Terms change, so check the live page before you sign.
Which network does iD Mobile use?
Coverage is the first thing to settle in any iD Mobile review, and iD’s own pages are not entirely consistent about it.
iD’s coverage page is unambiguous: “All iD Mobile services run on Three’s network.” It calls Three its network partner and compares Three’s spectrum against Vodafone, O2 and EE as rivals. iD’s Why iD page, meanwhile, lists “faster and more reliable 4G/5G coverage, thanks to the VodafoneThree merger” among the reasons to join.
Both of those are iD’s words, written on the same site. The practical read is that the signal you get is Three’s signal, and that iD expects the merger to improve it over time. If you want to know what you will actually get, the network behind the brand is Three, so check Three’s coverage at your address.
iD says its 4G network covers 99% of the UK, with 5G access in over 615 locations. Those are iD’s own figures, and a national number tells you very little about one street, so put your postcode into a coverage checker before you commit.
Wi-Fi calling is listed as a feature, which helps if your signal indoors is patchy. iD also lists coverage on parts of the London Underground. If you already know Three works well where you live and work, that is the strongest point in any iD Mobile review.

What plans does iD Mobile offer?
iD Mobile offers three ways in: a phone on a 24 month plan, SIM only on 1, 12 or 24 month plans, and pay as you go. It also sells refurbished phones and SIM free handsets through the same site.
For most people reading an iD Mobile review, SIM only is the place to start, because it keeps the commitment short and the terms simpler. A 1 month plan lets you test the Three network where you live before you tie yourself in for longer.
We have deliberately left prices out of this iD Mobile review. They change often, and a number typed into a blog goes stale fast. Current plans and prices are on our iD Mobile deals page, which is kept up to date.
If you are weighing iD against other smaller networks that borrow the big operators’ masts, our guide to cheap mobile networks explains how that works.
Does iD Mobile put prices up mid contract?
It depends on what you buy, and it is the part of an iD Mobile review that most affects your total cost. iD’s price increases page says the annual fixed price increase does not apply if you are a SIM Only customer, a Pay as You Go customer, or you bought a 24 month phone plan before 15 January 2025. Other phone plans do get it.
According to iD, the rise on affected phone plans is a fixed amount added to your monthly price each April:
- £1.50 a month if you joined or upgraded on or before 10 March 2026
- £1.80 a month if you joined or upgraded from 11 March 2026 onwards
iD says the amount stays the same if you change plan during your contract. It is applied to the new plan price instead. Because the rise is set in pounds and pence, you can work out the total cost of a phone plan before you sign. Add it to your sums.

Key takeaways
- iD Mobile runs on Three’s network, so check Three’s coverage at your address.
- SIM only and pay as you go plans have no annual fixed price rise, according to iD. Nor do 24 month phone plans bought before 15 January 2025.
- Other phone plans go up by a fixed £1.50 or £1.80 a month each April, depending on when you joined.
- Roaming in iD’s 50 inclusive destinations comes with every plan, with a 30GB data limit.
- Ofcom listed iD among the providers with the fewest pay-monthly mobile complaints for April to June 2026.
Roaming with iD Mobile
If you travel, this is the part of the iD Mobile review to read closely. Inclusive roaming is the feature iD talks about most. Its roaming page says every plan comes with 50 inclusive roaming destinations, where you use your inclusive data, up to 30GB, to stream and browse just like you were at home. iD says that is more destinations than any other UK network.
Outside those 50, iD sells Roam Beyond data add-ons for travel further afield. Calls and texts outside the inclusive list are charged separately, so look up the country on iD’s roaming page before you go.
Ships and ferries are a different story, because they use satellite connections rather than a local network. On ships, ferries and cruise liners, iD lists calls to UK numbers at £6 a minute, calls received at £1.50 a minute, texts to the UK at £1.20 each and data at £9.60 per MB. iD recommends not using your phone and keeping it in flight mode until you get to shore. iD also offers a bill cap, which is worth setting before any trip.
iD Mobile customer service and complaints
For an iD Mobile review, the useful questions are how to complain and what happens if iD does not fix it. iD’s complaints procedure page says you can raise one online or by phone. Its complaint agents are available Monday to Friday from 9am to 8pm, and from 9am to 6pm at weekends and on bank holidays. For general account help, iD points to Live Chat and its community forum.
If a complaint is still unresolved after six weeks, or iD sends a deadlock letter, you can take it to the ombudsman, Ombudsman Services: Communications. That right applies whichever network you are with.
On complaints data, Ofcom’s latest figures, published on 26 October 2026 and covering April to June 2026, named EE, Giffgaff, Tesco Mobile, Three, Vodafone and iD Mobile as generating the fewest pay-monthly mobile complaints. O2 and Sky Mobile generated the most in that quarter. Ofcom notes that complaints about mobile services stayed the same compared with the previous quarter. One quarter is a snapshot rather than a verdict, so this iD Mobile review treats it as a good sign, not proof.
Who does iD Mobile suit?
Going by iD’s own terms and Ofcom’s data, iD Mobile looks like a reasonable fit if:
- Three’s signal is good where you live and work
- You want a SIM only plan with no annual price rise
- You travel in Europe and want roaming included without a daily charge
- You like the option of a 1 month plan to try the network first
It suits you less if Three’s coverage is weak at your address, or if you want a phone plan with no yearly rise at all. In that case the fixed April increase is simply part of the price.
The honest summary of any iD Mobile review is that the network matters more than the brand. Check coverage, check the plan length, and compare iD’s current deals against the rest before you commit.
