I'm in Spain with a Pixel 3 XL. It isn't connecting to any networks. I've turned on roaming and tried resetting wifi + data settings.
Please help, obviously with no service i can't debug easily.
Have you set up Easy Roam on your plan? Setting it up also triggers the International Roaming option on your plan. Without International Roaming, your phone won't connect to international partners.
Have you had success connecting to local carriers in other countries on your travels, or is the issue unique to Spain?
