Fake technical support: they steal your WhatsApp with a code

Call from a supposed "+Móvil technical support." The scammer confirms your number and asks for the cell phone model, then says they will send a code via WhatsApp to "verify the signal" and asks you to dictate it to them. In reality, it is the WhatsApp linking code: if you share it, they take control of your account to scam your contacts. Do not share the code with anyone. Hang up and block the number.
