Account showing texts I didn't send

Hi I lost my phone, didn't realise for several hours. New sim received, old one cancelled, same number. Concerned re access and facebook already hacked. Checking my account I sent 2 texts to 2 separate people but account shows I sent 3 to each of them. Could my ''old'' sim be out there/texts being sent from my number? Thanks

I think it's very unlikely that the old SIM is still active if you've already received and activated the replacement Kathbr but if you're concerned then give customer support a should so they can confirm.

Thank you , I'm in Portugal ATM and my son will bring over my new SIM can I activate it whilst in Portugal,?

The SIM will need to be activated in the UK Janas1 so I'd suggest your son pops it in a phone before leaving the UK to ensure the SIM is properly activated.

Hi Martin, I didn't see your msg until after my son arrived. But the SIM worked thank goodness. Thx gif your help 😀

Good to hear Janas1, thanks for letting me know. I hope your son has a good trip and if any other issues come up let us know.
