How scams that copy phone and broadband providers work

UK Finance says criminals pose as communications providers and ask for remote access to "fix" a problem. The FCA says that once a scammer can see your screen, they can reach your online banking.

Tech support and broadband scam calls

This could still be a scam call

Criminals can make their number look like a genuine one (this is called spoofing). If someone calls from this number and asks for money, bank details, a code or passwords, hang up. Then call Tesco Mobile back on a number you've found yourself, such as the one on their own website or on a letter or bill from them.
