Question: I am using Airtel mobile services. The company will use the four numbers of the three phones. Why are unable to keep in mind that there is no number. What must be set in order to never call his number?

Your mobile service provider Airtel, because there is no phone in the SIM number to know where you want to * 121 * 9 # and type of stress, your SIM number, the message becomes available to you.
