iD Mobile: brand review

Sustained value pricing on Three's infrastructure has made iD one of the country's fastest-growing brands among deliberate switchers.

Published: Northgate Review editorial deskLast reviewed: July 2026Reading time: 4 minutesJurisdiction: United Kingdom

Summary of key points

iD Mobile leases Three's infrastructure entirely.
The proposition is value pricing among monthly plans, with rapid subscriber growth.
The brand operates its own application, support and capability schedule.
Confirm eSIM, Wi-Fi Calling and 5G support per handset before reliance.

I.The proposition

iD Mobile, associated with the Currys retail group, contests the value segment of monthly plans and has grown at pace on the strength of it. The physics are Three's; the application, support and capability schedule are iD's own.

II.Practical considerations

Coverage: Three's — read the Three review for the pattern, then apply the postcode method. Where Three is weak at an address, no plan price remedies it.
Capabilities: evolve independently of Three's — confirm per handset officially.
Congestion: the standard hosted-brand caveat at saturated cells applies.
Switching: the universal free procedure — PAC to 65075.
