Hi, I'm on holiday in Turkey, understand it's outside the EU so calls & data are outside my allowance, but can't seem to make calls or send texts, can receive ok and texts send via WiFi calling in the hotel WiFi coverage. International Roaming is On in the app, but data is turned off. Can't determine what network I've been connected to - which one should I be on? Didn't receive the "configuration/Welcome To Turkey" text messages when we landed. Added +44 to phone/text numbers. WiFi calling works in the hotel WiFi coverage. Phone is Samsung Note 9 on Android. Any help being able to text and make calls would be appreciated - thanks!
