Coverage – iD Mobile

iD Mobile is a Three UK MVNO, meaning iD Mobile uses the Three UK network and does not have its own mobile infrastructure.

To find out what to expect in terms of coverage with iD Mobile, jump to the Three UK Coverage section in my United Kingdom SIM card buying guide.

iD Mobile customers have access to Three UK's 5G NR network.

SIM Card Price – iD Mobile

You can buy an iD Mobile SIM card starting from 6 GBP in Carphone Warehouse stores or Curry's stores.

You can consider getting a travel eSIM for United Kingdom, which can, in specific scenarios, be cheaper than getting a SIM card from iD Mobile.

Especially if you get a Europe-wide eSIM (for when you visit at least two or more supported European countries) or a global eSIM (for frequent travelers visiting multiple continents).

In my United Kingdom eSIM buying guide, I analyze various eSIM options of eSIM providers I have tested extensively worldwide.

But I will introduce them here quickly:

  • Airalo: Uki Mobile (United Kingdom only), Eurolink (39 countries in Europe) & Discover+ (130 countries worldwide + up to 200 worldwide minutes & 200 worldwide SMS) – use code NEWTOAIRALO15 (15% off – first-time users only) or AIRALOESIM10 (10% off)
  • Alosim: United Kingdom & Europe (32 countries) – use code PTW (5% off – no limits)
  • Holafly: United Kingdom & Europe (32 countries) – all variants in both options include unlimited data + up to 120 Europe-wide calls – use code PHONETRAVELWIZ (5% off – no limits)
  • Nomad: United Kingdom, Europe (30 or 35 countries, depending on the variant) & Global (109 or 139 countries, depending on the variant) – use code ADU123 (3 USD off – first-time users only)

Once again, check out my United Kingdom eSIM buying guide to learn more about these eSIM options.

iD Mobile top-up vouchers are sold in Carphone Warehouse stores or Curry's stores.

To top up your iD Mobile SIM card, call 7777 and follow the instructions.

You can also recharge online with debit and credit cards. However, mostly UK-issued cards are accepted.

You can also top up and check your balance on the iD Mobile app (Android/iOS).
