Ok, so my sister and her hubby go to Scotland to visit my niece. I guide them on how to set up their phones. They both use the iPhone 5. Cellular off, voice roaming off, push off for mail. It may have been overkill, but she wanted to be sure no huge charges. So they get there and his phone works on wifi and hers does not. She said Airplane Mode was off. She said both phones are set the same in settings. I suggested she Reset Network Settings. But she wants to wait until they get to another destination tomorrow. She believes it's the wifi where they are. But his works fine. Other than trying Reset Network Settings, any other ideas?
