Wrong SIM delivered how to get a mini SIM

I bought a phone for my elderly aunt (EasyPhone) and a Lebara package for data and calls via a SIM only deal. The SIM has arrived but does not fit the phone. I cannot see how to swap this sim to get the right size, can anyone point me to how to do this please?

Marilyn Use an adapter. Usually a set of adapters to handle all situations.

The sim that comes with Lebara should be 3 in 1 you should be able to chose which one by snapping away one you don't need
