About iD Mobile
iD Mobile is an MVNO owned by Currys plc (the UK's largest electrical retailer) and runs on Three's (now VodafoneThree's) network. Launched in May 2015, iD Mobile has grown to over 2.2 million subscribers and is the UK's fastest-growing MVNO. Key differentiators: data rollover on all plans, inclusive roaming in 50 destinations, a written pledge against CPI/RPI price rises on SIM Only plans, and in-store support at Currys nationwide.
