Hey Frank and team - Would be so great if this could be fixed soon, I'm surprised to find it's been a problem since the first feature request for this in 2016.
Getting geo-location to automatically set the SMS country code (rather than it being overridden by the contact owner's country code) seems like a no brainer/ expected behaviour.
Support told me that the only option is to add a country field to all our optin forms, which seems like a clunky workaround, which we want to avoid, as more fields = reduced conversions.
To me this seems less like a feature request and more like a fix of a missing link up between geo-locate + SMS.
