Introduction
If you've been shopping around for a new SIM deal or phone contract lately, chances are ID Mobile has popped up on your radar. Owned by Currys and running on the Three network, this MVNO (Mobile Virtual Network Operator) has quietly built a loyal following — joining over 2.5 million subscribers on Pay Monthly Phones and Fixed Price Sim Only Deals from £6 a month. Here are ten reasons real customers are making the switch in 2026.
Genuinely Fast 5G Speeds
Because ID Mobile uses the Three network, which offers the fastest median 5G download speeds in the UK, users aren't settling for second-best performance just because they've chosen a budget-friendly provider. Independent testing found extremely fast 5G on ID Mobile, generally over 200 Mbps on an Android phone, with strong results in suburban and urban areas too.
Reliable 4G Where It Counts
It's not just 5G that impresses. 4G performance is consistently very good, and testers reported no issues with call performance or dropouts during their time on the network.
Near-Total UK Coverage
As an MVNO riding on Three's infrastructure, ID Mobile customers benefit from 99% population coverage across the UK. That's a big deal for anyone who's been burned by patchy service on a discount network before.
Free Data Rollover
One of ID Mobile's signature perks is data rollover, a feature that lets you keep the data you didn't use up in one month, to use in the next. If your usage varies month to month, this alone can save you from unnecessary top-ups.
Roaming That Actually Rolls With You
While plenty0 of major networks have quietly reintroduced EU roaming charges, ID Mobile has kept theirs and made it even better, letting customers use their regular minutes, texts, and data in the EU and additional non-EU countries. Better still, the fair usage policy is generous — you can use your normal data allowance up to 30GB while abroad. According to Trustpilot, ID Mobile offers inclusive roaming in 50 destinations, more than any other UK network.
Budget-Friendly Plans With No Compromise
ID Mobile has built its reputation on value. Plans start from £6 a month, and there's a huge range of SIM deals to choose from on 1-month, 12-month, or 24-month contracts, with data allowances anywhere from 5GB up to unlimited.
Flexible Contract Lengths
Not everyone wants to commit long-term, and ID Mobile gets that. SIM deals are available on 30-day rolling contracts as well as 12-month and 24-month plans, so you can pick the commitment level that suits you — whether that's testing the waters or locking in a longer-term saving.
Every SIM Is 5G-Ready
There's no premium tier just to access faster speeds. All SIMs are 5G-ready at no extra cost — as long as your handset supports it, you're good to go from day one.
Solid Customer Satisfaction Scores
Real users seem happy with the service they're getting. In Which?'s customer satisfaction survey, ID Mobile scored 73%, placing it joint 10th out of 15 providers, with customers praising the network for being easy to deal with, offering a good price for what you get. Trustpilot reviews echo this, with long-standing customers reporting that issues get solved with patience and kindness when they do call in.
A Genuinely Improved Network Experience
Perhaps the most compelling reason to switch is simply that ID Mobile has gotten noticeably better over time. Reviewers note it's noticeably better than just a few years ago, with data speeds that can be absolutely superb on 5G in the right places. Add in instant eSIM activation and what are considered some of the best WiFi calling and 4G calling (VoLTE) features of any virtual mobile operator, and it's easy to see why so many are making the jump.
Final Thoughts
For UK users looking for a network that combines fast Three-powered speeds, generous roaming, flexible contracts, and rock-bottom pricing, ID Mobile makes a compelling case. It's easy to see why thousands are switching to ID Mobile in 2026.
