Overview
iD Mobile is a mobile virtual network operator owned by Currys plc, one of the UK's largest electronics retailers. Launched in 2015, it operates on Three's network infrastructure, giving customers access to extensive 4G and growing 5G coverage across the United Kingdom. iD Mobile has quickly established itself as one of the most compelling budget-friendly networks, consistently offering aggressive pricing on SIM-only and pay monthly phone deals without compromising on features.
iD Mobile differentiates itself by including a generous set of features as standard on every plan. All tariffs come with unlimited UK calls and texts, 5G access at no extra cost, free data rollover for unused allowances, and inclusive roaming in 50 worldwide destinations. The network also supports eSIM, WiFi calling, and 4G calling (VoLTE), making it one of the most feature-rich MVNOs on the market.
In January 2026, iD Mobile committed to maintaining fixed-price SIM-only plans, guaranteeing no mid-contract price rises for customers on eligible tariffs. This move further cemented its reputation as a transparent, customer-first network that prioritises value and simplicity.
Coverage & Speed
iD Mobile uses Three's network, which provides 4G coverage to around 99% of the UK population. 5G coverage is expanding rapidly and is already available in hundreds of towns and cities. As an MVNO on Three, iD Mobile customers benefit from the same coverage footprint, and independent testing shows speeds that are comparable to Three's own service.
Plans & Pricing
iD Mobile offers a wide range of plans to suit different budgets and usage needs, from light data users to heavy streamers. All plans include unlimited UK calls and texts, 5G access, data rollover, and roaming in 50 destinations.
Roaming
iD Mobile includes roaming in 50 destinations worldwide at no extra cost on all plans. You can use your UK allowance of minutes, texts, and data (capped at 30GB if your plan includes 30GB or more) abroad. For destinations outside the included 50, data-only Roam Beyond add-ons are available for 35 additional countries, starting from 5 pounds. This is one of the most generous roaming offerings among UK MVNOs.
Our Verdict
iD Mobile is one of the strongest MVNOs in the UK market, offering a combination of low prices and premium features that is hard to beat. Running on Three's network gives it solid 4G coverage across the country and growing 5G availability, while its inclusive approach to features like data rollover, 5G access, and international roaming sets it apart from many competitors at the same price point.
The network is particularly well-suited to anyone who wants simplicity and value. There are no hidden charges or paid-for extras that should really be included as standard. The commitment to fixed-price plans is a welcome move in a market where mid-contract price rises have become the norm.
The main consideration is that Three's network, while excellent in urban areas, can occasionally lag behind rivals in very remote or rural locations. If you live in a well-covered area, however, iD Mobile represents outstanding value for money and is a genuine alternative to the big four networks.
