Did he activate the SIM successfully?
What make and model of phone is it?
Is the phone unlocked for use on any network?
What happens when the SIM is inserted into the phone?
Any error messages?
What exactly is/isn't working?
Connection to the 48 network - i.e. signal bars?
Incoming/outgoing calls?
Incoming/outgoing texts?
If mobile data isn't working then are the APN settings configured correctly?
Did he buy a monthly membership plan in order to be able to use outgoing services (other than the free introductory 1GB of 4G mobile data)?
