United Kingdom

13 operators
The UK has around 80 million mobile subscriptions with SIM penetration above 115%, dominated by four operators: EE (BT, market leader), Vodafone UK, O2 UK (Virgin Media O2, with Vodafone-Three merger under discussion), and Three UK, alongside numerous MVNOs like GiffGaff and Tesco Mobile. Postpaid dominates, and USSD use is limited — mainly for balance and own-number checks, with daily self-service handled through carrier apps.
