I've arrived in Switzerland and now I cannot make or receive calls. I visit Switzerland twice every year and have never had an issue before. Although this is a fairly new phone.
I've checked my roaming is on, my international call barring is off.
Thanks for your post and welcome to our community.
Very sorry you're having some issues using the services in Switzerland, I can appreciate you're keen to know what's going on.
As you mentioned it's a new phone, were you also given a new SIM card?
I'd love to know more and take a quick look at your account, therefore I'll pop you a personal message now and we'll take it from there.
