A new service has been launched in the United Arab Emirates that allows residents to block annoying spam calls.
The UAE Telecommunications Authority (TRA) has begun to fight advertising calls from mobile operators Etisalat and du.
TRA offers subscribers the ability to block such calls. In order to stop receiving calls with promotional offers from Etisalat, you must send an SMS with the text "DNC" to 1451. du subscribers must send an empty SMS message to 5293.
