[inquisitor]

Customer support has just called me back and obviously the issue of lacking country codes when being called on the US number has been resolved. By the way I was impressed that toggle supports call waiting, which not many prepaid operators do.
On that occasion I also asked for Belgian numbers since I'm also getting the "Country alias is invalid" message when trying to register such and the gentleman told me that Belgium should not appear on the website as it has not been launched yet as toggle country.
I also made them aware of Switzerland being called "Swiss" in the drop-down menu, after the retired senior marketing officer for toggle obviously didn't consider my long list of issues and proposals I sent her almost a year ago.
