Living in Chelyabinsk, I believe I'm rather capable to recognize the difference. Yekaterinburg is at least 300km from the nearest part of Kazakhstan (which up to a few days ago wasn't even officially permitted there). So no, there is no indication that there is any kind of geo-fencing for roaming devices, be them in Russia, China, Iran or Afghanistan.
