When I insert the new sim card and turn phone on it is saying wrong card. I have tried turning it off and on again and leaving it 10 minutes but still saying wrong card.
It is an old Samsung phone and the IMEI number is: [REMOVED]
I'm wondering if the new sim card is incompatible with this model of phone?

I tried the sim on a newer phone and it worked fine. I just think the current old phone I have the sim sent to me is not compatible.
