UK customers can save £600 with little-known code

Mobile phone bills in the UK are expected to rise in April, but new regulations from Ofcom will prevent inflation-linked price increases in new contracts. Existing customers may still face mid-contract hikes, so checking contract status is advised. Experts recommend switching to SIM-only deals for potential savings of over £350 a year. Many providers offer flexible contracts and additional benefits, making it easier for customers to find better options. To secure the best deals, customers should research competitors, negotiate with their current provider, and consider their data usage. Price comparison websites can help identify suitable plans before contracts expire.
