Calling uk from Canada

Hi I’m having issues phoning the uk from Canada

Do you have a roaming add-on active Paul60?

I have the same issue. I bought a travel esim for Canada. I have chatted to both Lebara Uk and Lebara Travel Sim help team but still no success in making or receiving calls on phone line after making sure settings were correct.. What solution can you advise for iPhone 17.

Hi yes I have international add on 50/50 left still can’t phone uk
