Hello @Foxy44 ,
Welcome to the community,
Did your son remember to activate roaming on his account, or if the account is in your name, did you do so? This only applies to contract customers not pay as you go customers as those are automatically activated.
If roaming is active, has he tried to do a manual search rather than automatic search?
If he or you need to activate roaming, you can do this either by ringing customer service or if he has to do it himself, then by using something like Skype, he can do this for free:+448000798586.
To contact EE customer service dial 150 from your mobile phone or ring customer service for free using Skype or another phone: +44 800 079 8586 or +44 800 956 6000.
