Probably a mistake to reveal this info. After recovering the SIM, it may have been possible to go back and see the network traffic from the drone. That could create an opportunity to disrupt or hijack drone c&c in the future.
Most likely it is encrypted and so there isn't anything useful to learn.
Frequency of transmissions and amount of data transmitted should offer some information.
I wouldn't be so sure if they have to use Ukraine's cell network, but possibly
