With over 2.5 million subscribers, iD Mobile has become one of the UK’s most popular budget network providers — and the best iD Mobile deals make it easy to see why. Backed by Currys and running on Vodafone and Three infrastructure, iD Mobile offers SIM-only plans from £6 a month alongside pay-monthly handset contracts, all with fixed pricing and no mid-contract price rises.
Whether you are hunting for the cheapest SIM-only deal or a low-cost way to spread the cost of a new handset, iD Mobile deals consistently rank among the strongest in the MVNO market. BudgetFitter tracks verified iD Mobile offers so members can find the current best price without trawling comparison sites.
iD Mobile operates as a mobile virtual network operator (MVNO), meaning it leases capacity from established networks rather than owning its own masts. In practice, subscribers benefit from 99% UK outdoor coverage and 5G access on eligible plans — comparable to full-price network contracts at a fraction of the cost.
Signing up is straightforward: choose a plan online, receive your SIM, and activate via the iD Mobile app. Existing customers can transfer their number using a PAC code (text PAC to 65075), which networks are required by Ofcom to provide within two hours. Rolling monthly plans mean no long-term commitment, while 12 and 24-month contracts unlock lower monthly prices.
Two features set iD Mobile apart from most rivals. First, data rollover: any unused data from your monthly allowance carries forward to the following month, up to a 200GB cap. For light users, this means data effectively accumulates rather than being wasted. Second, inclusive international roaming in 50 destinations is bundled into most plans — no bolt-ons required for EU travel.
Fixed pricing is another differentiator. Unlike some of the major networks that apply annual above-inflation price increases mid-contract, iD Mobile has offered fixed-price guarantees on selected plans. Uswitch has recognised iD Mobile with awards for best data SIM and best value SIM, and the provider holds strong ratings across independent review platforms.
SIM-only plans are the most flexible option: no device cost, no long contract, and prices starting under £10 a month for generous data allowances. iD Mobile’s SIM-only range includes 1-month rolling plans for maximum flexibility and longer-term contracts at reduced monthly rates. For data-heavy users, unlimited data SIM-only plans are available, making iD Mobile a practical alternative to broadband for light home internet users.
Pay-monthly handset deals bundle the cost of a new or refurbished phone into the monthly bill. iD Mobile sells handsets from Samsung, Apple, and other manufacturers alongside SIM-free and refurbished options through its Currys partnership. For shoppers comparing network options, the UK Mobile Network Matcher on BudgetFitter helps identify which provider suits a specific coverage area and data requirement.
BudgetFitter lists current iD Mobile deals including SIM-only plans, cashback offers, and pay-monthly handset promotions. The verified deals section above reflects the latest available offers. For members comparing iD Mobile against similar MVNOs, giffgaff and SMARTY Mobile are popular alternatives with their own verified deals on BudgetFitter. Those seeking travel-focused connectivity may also find Airalo eSIM useful for international trips where a local data plan is more cost-effective than roaming.
