Wife and daughter currently in the UK, both with Iphones (6+ and 7+). Neither of them can connect to the UK cell networks. They've tried restarting their phones. setting network selection to automatic, and trying manually to connect. No luck.

Thanks for the quick answers. I've enabled voice roaming on both phones. Will see if it works for them once I can get hold of them again! 🙂
