Calls from Tesco Mobile numbers

Tesco Mobile provides mobile phone service to customers right across the UK. Tesco Mobile doesn't have its own masts. It is a virtual network (MVNO) that runs on O2. Nobody has looked up a Tesco Mobile number on Who Called Me Check yet. If one rang you, search it and be the first to report it. As on every network, some of its numbers are used for nuisance and scam calls, such as one-ring call-back tricks and fake bank, delivery or HMRC calls. Spam filters stop some of them, not all, so look up a number you don't know before sharing anything personal or paying for anything.

Every UK mobile number has 11 digits and starts 07. The digits that follow were originally issued in blocks to individual networks, so they hint at where the number started life. But because anyone can keep their number when they switch, a number that began on Tesco Mobile may have moved on, and one from another network may now be with Tesco Mobile.

Many smaller brands also run on a bigger network's masts. Either way, knowing the network tells you nothing about the person calling or whether the call is genuine. That's what the reports are for.

Tesco Mobile doesn't run its own network. It uses O2, so Ofcom hasn't issued it any number blocks of its own. New Tesco Mobile customers usually get a number from O2's ranges, and others bring their number with them, so the prefix tells you very little about whether a number is on Tesco Mobile.

The ranges are listed on the O2 page, or you can browse every range holder.
