Pocsag data - unexpected transmission

[Ngood94323]

Hi all. I have been monitoring some pocsag transmission around 153mhz which I am receiving ok but I found some insusal ones I didn’t expect. They are relating to giffgaff the mobile phone operator who I believe use O2. It is as if text messages sent to a mobile are then being sent via pocsag to a pager. Does that sound right? Or can anyone explain? At one point a conversation seemed to be going backwards and forwards.

There are several gateways to allow messages to cross from one system into another...used by telecoms, SAR, delivery companies etc.

Yep, had a few interesting catches like that.
