Coverage in the Siberia major cities is reasonable and reliable. You can choose almost any operator, but better check the coverage map for more details. Totally no issues in Novosibirsk (MegaFon is best, MTS is very good, Tele2 good enough, Yota is good), pretty good in Omsk (MTS plays the best there and MegaFon is reliable).

CHECK VERY CAREFULLY for rural areas and small towns at the countryside. Or have 2-3 SIM cards (cheap enough but good backup) if you really need reliable connection in these towns.

Far East goes apart.

MegaFon is strong but weakens a bit after Kansk. MTS is generally working there normally. Vladivostok has lots of humps, up-and-down hills which makes a heavy job for a radiowaves to cover it all around. You can use MTS, MegaFon and Yota there.

And mind about some special zones - Sakhalin island, Kamchatka peninsula, Taymyr region. This harsh regions excluded from almost all nation-wide data packages, and Internet access goes there only with a surcharge. You can buy local-issued SIM card with very small and expensive enough packages.

Do not rely too much on coverage along the highways. Even the Transsib railroad has lots of gaps between stations where you can't use any mobile network.
