You could ask him to restart the phone and see if the phone connects to a local roaming network.if it doesn't,try to reset network settings.

I assumed that account also had international voice and data roaming add-ons. 

Thanks for replying,I will pass him the message tomorrow as it is 4 hours ahead, will he how he makes out in morning. Will keep you updated 

Yes had everything on the plan, minutes, data and texting 

@Bunny77 - Looks likes restarting the phone worked. I can see that the phone was finally able to connect to the network in Spain

I believe so. Will know for certain later today

Thank you
