Hello! I'm trying to setup SMS notifs on OpsGenie.
I could verify my Austrian A1 number without issues, but my Movistar Argentina mobile throws an error, despite the line being valid:

I manage to add the number for the voice feature, but I never receive the verification call.
Any ideas why? I tried all possible formatting options (I work for a phone company) so I get the feeling my phone number is ok, the problem is OpsGenie.
