Good morning fellow users!

I need help to recover txt messages please. I have accidentally deleted a close family member from my mobile phone contact list, but, worse than that, all subsequent text messages between us have also been automatically deleted.

I re-entered the contact name and phone number but alas the text messages did not re-appear

I did not back up my phone nor did I have the phone set to save to the Phone and SIM or the SIM Card.

I would be grateful for any assistance you could give me, perhaps you might be aware of software that might possibly retrieve the deleted messages?

I thank you one and all in advance for your help.

Kindest Regards
