It actually makes a lot of sense. A lot of pagers operate on lower frequencies (~100 mhz instead of 400 or 700) that can penetrate way deeper than the higher frequencies used by modern phones. Plus the data rate is substantially lower, which acts in the favor of getting reception.

So yeah it makes a ton of sense. These are very different devices operating using different frequencies and protocols.

Pagers are typically unidirectional. So a client's inability to transmit back an ACK deep inside a building is not a constraint. Just crank up the broadcast power on the network side.
