Not receiving SMS from App

like usual, great design forcing players to use Auth App when its not working,
so i cannot use the LFG description unless i secure my account,
downloaded the App, but am not receiving any SMS confirmation for hours
i literally went and bought 2 other different GSM operators and all of them not receiving any SMS,
i tested some websites like facebook etc… all of them work fine except out beloved company

am from Tunisia by the way, and i remember last year i was able to get the SMS for another account. but not today
