iD Mobile is a budget-friendly MVNO owned by Currys, the UK's largest electronics retailer, running on Vodafone's network. Known for competitive pricing and a useful data rollover feature, iD Mobile gives customers access to Vodafone's extensive 4G and 5G coverage at lower monthly costs.

About iD Mobile Coverage

iD Mobile was launched by Currys (formerly Carphone Warehouse and Dixons) in 2015 as an own-brand mobile network designed to offer great value on Vodafone's infrastructure. Operating on Vodafone's network, iD Mobile provides 4G coverage across over 99% of the UK population and access to Vodafone's expanding 5G network in supported areas. This gives customers the confidence of a major network at prices that frequently undercut the big four.

One of iD Mobile's most popular features is data rollover, which automatically carries any unused data from your current month into the next. This means you're not losing out if you have a quieter month of data usage. iD Mobile also offers bill capping, so you can set a spending limit and never face unexpected charges. Plans range from budget SIM-only deals to phone contracts with the latest handsets, all available through Currys stores and online.

Coverage on iD Mobile is determined by Vodafone's network infrastructure. Vodafone's 4G network is well established across the UK, performing strongly in urban centres and with good suburban reach. Vodafone's 5G rollout is progressing in major cities, and iD Mobile customers on eligible plans can access these faster speeds. Vodafone is also part of the Shared Rural Network initiative, which continues to bring improved 4G coverage to rural communities.

Enter your postcode into our coverage checker above to see how Vodafone's network performs at your location. The results will show you 4G and 5G availability that directly applies to iD Mobile. If you're near a Currys store, you can also get hands-on advice about iD Mobile plans and coverage in your area.
