Win Mobile is actually a division of MTS Russia (not MTS-Ukraine). It uses the equipment of former Ukrainian MTS on Crimea peninsula but all network core and billing is actually merged with MTS Russia (Krasnodar region). They do not talking about this, but it is true. If you take a SIM card of MTS Krasnodar to Crimea, it will register in Win Mobile as in its native network without roaming.

Consider moving Crimea to Russian Federation due to tight relationship with MTS. It can be useful for visitors - one SIM card (MTS Krasnodar) for Russia and Crimea.

Also THERE IS NO ROAMING FOR UKRAININANS in Crimea. Neither of Ukraine GSM providers will work in Crimea. At all. Even MTS-UA.
