No, technically every SIM gets activated only when mobile phone provider gets the user's documents copy & a verification call comes from mobile company's service center to an existing number of yours or family (& you verify your documents details). If you don't have a existing number to reach, they make you to bring documents to official store. There is no pre activated SIM cards. Mostly, like any other country, this happened because they found bad people were using pre activated sim cards for terrorism. My exiting phone number is now 14 years old, same provider, prepaid. I have been required to submit updated KYC about 4 times in these years.
