beeline was the first of the main operations to disconnect Moscow and the Moscow region from the 3G communication standard.
3G frequencies at 2.1 GHz are transferred to LTE, and the remaining 900 MHz band is reserved for voice communications only. 2G frequencies also continue to work.
It is noted that owners of smartphones with only 3G support can replace the device with a new one if they want to continue using the Internet. These are only 3% of the entire customer base.
Refarming (approx. frequency substitution) allows the operator to increase the capacity of the data network by 50%.
Full transition is planned closer to September. By the end of 2023, the operator wants to stop 3G in more than 25 regions of Russia. [Коммерсантъ]
