Service "Who called?" it is very convenient, because it makes it possible to find out about missed calls and listen to the left voice messages. Therefore, if for some reason you cannot answer or are out of the network coverage area, you will always be aware of who called you and when.
Instructions
Step 1
You can activate the service from the Megafon operator by simply typing * 105 * 170 * 0 # on the keyboard. If you have previously activated the "Voice Mail" service, then when you activate the "Who Called" service, the first one will be automatically disabled. With the help of the service "Who called" you can get information about missed calls and left voice messages. Such information will come from the service number 0525 in the form of an SMS message.
Step 2
In "Beeline" there is a service called "Be in the know" (the essence of it is the same as the service "Who called"). It connects to the free number * 110 * 401 #. Thanks to this service, you will really always be aware of what is happening. If a call was missed or the phone was completely out of the network, you will receive a timely notification in the form of an SMS message about this.
Step 3
MTS subscribers need to dial ** 62 * + 79168920892 #. The service activation is free, the subscription fee is also not charged.
