I sent a request to a person to be a co-host for my apartment.
He has an airbnb account but he cannot validate his phone number.
I tried to do it myself by creating another account with a different email address.
Actually if I want to verify a french phone number (mobile one) I have no problem, I receive an SMS and go up to the end of the process.
However if I use an Israeli phone number as this co-host is there I don't receive any SMS, and the account stays "waiting" forever.
I tried it several times for 2 days with the exact same result.
The phone support had no clue of what's happening.
