Been a while since I was in the region, but coverage was spotty anywhere far from ADD last I was, and there are many comms dead areas particularly in border regions. Probably has got worse in some areas due to conflict. ADS-B doesn't help if you don't have coverage (unless you get a satellite feed, which at ADD... let's just say I'd be surprised).
