Network abroad

[Jbeacom]

Whenever I travel abroad I fail to connect to a network. I reboot my phone and nothing, I change from connecting to a network from automatic to manual and nothing, and then also reset my network settings and nothing. Can’t call O2 because they are only taking a limited amount of queries. Can someone please help me as I can make any phone calls or text. Thanks in advance for any help, would be appreciated.

Because you're not buying anything, O2 doesn't consider your call important, so use the Lost/Stolen or Fraud option if you have to, to get through.
