It's induction along the cable. Presumably the MKE400 was plugged in using a shielded XLR which soaked up the radio signal, whereas the Video Mic Pro has a coiled unshielded cable which basically acts as an antennae.
You might be able to reduce it by putting an RFI Choke on the cable just before the plug.
In an ideal world, have people put their phones in flight mode, or move to a new position. If you're clearly hearing GSM noise you're normally less than a few feet from the source.
Anyway you can bypass VGA? Or try another VGA cable, perhaps one with bigger chokes? (that lump at each end)

In theory, you could just buy a pack (pick the right diameter!) https://www.amazon.com/stardrift-10-Pack-Diameter-Suppressor-Industrial/dp/B015RDPNTW

But I honestly have no idea how effective any of these are. Keeping the signal digital through the whole path is the best option.
