iD Mobile is a UK mobile virtual network operator running on Three’s infrastructure, giving it access to 99% national coverage and 5G connectivity. Launched in 2015 under the Dixons Carphone group (now Currys), the brand has grown to serve over 2 million subscribers with a straightforward proposition: affordable plans with no unnecessary complications.
The core offering centres on SIM-only plans starting from £6 per month, available on flexible one-month, 12-month, or 24-month terms. Unlimited calls and texts come as standard — you only choose your data allowance. For those after a new handset, iD Mobile stocks the latest smartphones on pay monthly contracts, and refurbished phones are also available, each professionally tested and refreshed for a cheaper route into a new device.
Several features set the network apart from other budget providers. Data Rollover carries unused data into the next month, while Inclusive Roaming covers 50 destinations with up to 30GB of roaming data. Bill Capping lets you set a monthly spending limit through the app to prevent unexpected charges. The Loyalty Perks programme unlocks savings across partner brands, and the trade-in service pays for old devices — typically within 3-5 working days of receipt.
Between the automatic deals on SIM-only plans, handset discount codes, referral cashback, and student savings listed below, there are several straightforward ways to cut your monthly costs.
Using a code at iD Mobile takes a few steps.
When’s the best time to sign up with iD Mobile?
Black Friday in November consistently delivers iD Mobile’s biggest cuts — selected handsets have dropped by over £200, and SIM-only plans often come with doubled data at the same monthly price. January and back-to-school periods bring a second wave of deals, though usually less dramatic. If you can time your switch, Black Friday is the strongest window, especially on longer contracts where the monthly savings compound over the full term.
Should I go SIM-only or take out a pay monthly handset contract?
SIM-only plans are the smarter move if your phone still works — from £6 a month on one-month rolling terms. Pay monthly handset contracts suit those wanting a flagship without the upfront cost; codes like IDVC30PAYM reduce it further. The steepest introductory discounts tend to land on SIM-only plans, so buying a handset separately and pairing it with a SIM can sometimes yield better overall value.
How do I combine iD Mobile offers for maximum savings?
Layer your savings strategically. Start with an automatic deal on a SIM-only plan that includes an introductory discount and gift card bonus. Apply one code at checkout — iD Mobile allows one per order, so pick the most valuable. If you’re joining alongside a friend, share the referral link first so you both receive up to £35 cashback. Students should verify their status to unlock the £20 discount before placing any order.
What should I watch out for before signing up?
Inclusive Roaming covers 50 destinations, but roaming data caps at 30GB per month regardless of your home plan — worth noting on larger allowances. Bill Capping is available on every plan but off by default, so enable it through the app from day one. Refurbished handsets save money, but check the condition grade carefully — expectations vary between “good” and “pristine”.
