Text messages after migration from TalkTalk

[beachmat]

Since migrating my mobile from TalkTalk some months ago, I get a text message very morning telling me my SIM card has been changed. They are apparently from my landline which is still with TalkTalk, so I've contacted them and they have no idea about it. Is there any possibility they are being generated by the O2 system?

Thanks

I think I've turned off FMP properly now, so I'm just waiting to see if I get another text.

Well here's hoping 👍

That appears to have worked. Thanks for your suggestion. It would be helpful if Alcatel made the SIM change alert setting visible...
