a different scam?

This might help with understanding.

infoman have you tried to find out from your friend/relative if they have genuinely changed number?

Not everyone is aware that you can transfer your old number to a new phone.

Hello infoman
No need to apologise!
I knew that you meant a text, I’m still a bit confused though

Sorry every one,I should have said a text not a phone call,
am I forgiven?
Just keep safe every one.

you cannot put a sim from a broken phone into another phone unless that phone is a 'sim free'phone when purchased or been unlocked from any contract.

If you acquire a new phone after breaking your old one, it will be at "factory settings", so you can put in your old SIM.

If someone gives/sells you an old phone of theirs they should return the device to factory settings before giving you it.

infoman, I understand what you said in the OP. For those who don't, perhaps calling the supposed friend or relative on their old number might solve the problem by illustrating the scam.

Just 2 weeks ago I did have an e-mail from an old friend who I've not had contact with for some years asking if I could contact them urgently. Then heard nothing. DD - pointed out it was a scam.

Not had the phone text ones though.

Thanks for passing on the tip infoman

As I understand it, OP means scammers are contacting people on the pretence of being a known contact. Giving out a 'temporary' telephone number, which I can only assume gives them financial gain or the means to hack into the users phone. Just guessing.

A phone call?
Wouldn't you recognise the voice, if it's your friend or relative?
Or not, if it's not.

Hello infoman sorry, I’m another one who doesn’t understand your post.
I’ve read it a few times now.

Do you mean that you’ve had texts from your contacts asking you to use a new number?
If so, this is normal practice, in my experience anyway

?

Infoman more info needed if you actually have it?

I’m a bit lost off - how is that a scam?

I have never come across this one.

Think it must be scammers posing as friends?

Are you saying that your friends and relatives are calling you and saying they have changed their number or random strangers are calling saying they are a friend or relative who has changed their number?

Thank you. This whole mobile thing bamboozles me at the best of times.
