M3s 3G 2100MHz is missing. Mass problems with 3G internet!

All big operators in Russia: MTS,Beeline,TELE2,Megafon

2G and 4G internet is working, but 3g internet working only 3 minutes after reboot.

After 3 minutes 3G internet speed is less then 10kb/s

Specification is 3G = 900/2100MHz, but 2100MHz is missing!!

Should I return the phone or the manufacturer is going to fix that problem?
