Hey @Vlodek,

Sorry to hear you're having issues making calls.

What device make/model are you using? It's possible this could be related to a 3G switch-off in your area, I'd check out How to ensure your phone is ready for the 3G switch off .

Let me know if this doesn't seem relevant to the issues you're experiencing and I'll investigate further.

Thanks,

Kate
