Who we are
S4M is a small independent site run from Weymouth, Dorset. It began years ago as Search 4 Mobiles, a mobile phone comparison site. Today it helps people find the cheapest way to stay connected: travel eSIMs, SIM-only deals and the right phone.
We are independent. No mobile network or eSIM company owns or controls S4M.
How we make money
Some of the links on S4M are affiliate links. If you click one and buy a plan, the provider may pay us a commission. You pay the same price either way.
Every "Go to" button is labelled. "Affiliate link" means we may be paid if you buy. "Provider link" means we are not currently paid for that brand.
What commission never changes
- The order of our tables and tool results. They're sorted by price or value, never by what a provider pays us.
- Which providers we include. We list good options even when we earn nothing from them.
- What we say. If a plan has a catch, we tell you.
How we check prices
Prices come from providers' own websites and, where available, the data feeds they supply to comparison sites. Every table shows the date it was last checked. Dollar prices are converted to pounds at that day's exchange rate. Prices change often, so always confirm on the provider's site before you buy.
