Answer 1

Information not verified! Find information for your carrier, or look in the SIM card menu.
For Tele2, the “Tele-topic” function is provided with sending push notifications, and you can turn it off by requesting *152*0# and or deactivating it in the “Tele2 menu”.
To turn off push notifications to Megaphone, the easiest way is to dial *808*0# and the call button. Although you can use the Megafon menu.
For MTS, the command * 111 * 1212 * 2 # and a call are entered, or you can search for the desired item in MTS Services.
