Why Choose a SIM-Only Deal in the UK?

Unlike traditional phone contracts that lock you into expensive 24-month agreements, SIM-only plans give you flexibility and significant cost savings. With prices starting from just £5 per month, you can get unlimited calls, texts, and generous data allowances without paying for a handset you don't need.
