Sim not supported

I’m giving my old phone to my mum so she had just bought a SIM card. When I insert this into my old phone it comes up with a message saying sim not supported and I don’t know what I have to do next. Any help would be appreciated.

If you can't activate your iPhone - Apple Support - https://support.apple.com/HT201407 - "If your iPhone can't be activated or an alert says the activation server is unavailable or the SIM card is unsupported, learn what to do."

Your old iPhone appears to be locked to a cell / mobile carrier that is different to the one the sim card your mum will be using is for.


You would need to contact the cell / mobile carrier you were using with the old iPhone and request that they unlock the iPhone for use with other carriers.
