This is an interesting map indicating Russian cell phone use. How does it compare with the maps showing territory occupied by Russians? Where exactly is the bright spot to the NE, and the less bright spot more to the SW? I was unable to read any place names under the spots. There also appear to be 3 areas separated by some uncolored space. I wonder what that means? Are these where heavy fighting is taking place and people are too busy to use SIM cards? Or are these relatively unoccupied areas, or even some other reason?
Mostly, it provides a rough guess to the concentration of Russian forces at the time the image was taken, which was on or some time before May 12. The fact that the map exists at all shows Russian forces have real problems with logistics, operational security, and military order and discipline. This was Telenko's real point in sharing it.
My best guess is the bright spots in NE Ukraine are around Kharkiv for the bigger one and Severodonetsk for the smaller one. The one to the south is Kherson.
The gaps are were Russian presence is low or none because there is no Ukrainian forces to fight or no need to have a Russian presence. Directly North of Crimea, there is no Ukrainian presence, so there is no need for Russian forces to be there. When zooming on google maps to the gap south of the Severodonetsk, it looks like it is south of Kramatorsk and west of Bakhmut. That area may be farmland given how few towns and roads are there.
There have to be some places where Russian forces are using proper military communications that are encrypted and hard to detect. These will not show up on civilian SIM card phone maps.
This looks to be from late April-early May, after the retreat from Kiev when those troops were brought to the Izyum area - NE bright spot. The more troops in an area the brighter the color.
Absence of color = absence of Orcs
All of it is BS because Ukraine blocked all the Russian phones from its network and to call on any Russian number is impossible from Ukraine.
