I was not aware that T-Mobile is available in Russia. But apparently it is. This is the instructions I got on a chat group that I belong to. This is only if you want T-Mobile as your carrier:
T-Mobile SIM card
Offsite Biometrics Collection for Foreigners
When you order a T-Mobile SIM card, you can skip the hassle of registering on Gosuslugi and the Unified biometric system (UBS). Our representative will meet you at a location that’s convenient for you and take care of everything on the spot.
Regions where offsite collection is available
• Moscow and the Moscow Region
• Saint Petersburg and the Leningrad Region
• the Republic of Tatarstan
• the Sverdlovsk Region
• Krasnodar Krai
Offsite biometrics collection will soon become available in other regions as well.
What to expect at the appointment:
The representative will help you to obtain your SNILS online and set up a Gosuslugi profile.
They will then collect your biometrics by taking your photo and asking you to read some numbers aloud from a tablet.
Your SIM card will be ready to use right after the appointment.
