I have no service on holiday in France, I turned the account and device roaming options on on Monday. When I try to connect manually as suggested all the French networks have crossed out circles next to them? I can't take my battery out, but took my sim out and rebooted and still no joy.
Thanks for your response, I turned the data roaming on my account in France on Monday after realising that might be the problem, but the mobile option was already enabled. It does say no service at the top of the handset and then 'selected network unavailable' . Switching between 4g and 3g doesn't work.
