Birtley seems to be a blackspot for both EE and Three (have had 3G via both on my phone). i think it suffers simply from being Birtley in between transmitters.
I find it strange the way the GPS signal varies between buses. I was on the X12 coming from Newcastle with a 21 right behind me, and when I stopped at the Barley Mow stop the real time information stated: X12 Middlesbrough - due, but 21 Chester-le-Street 2min. Can't understand why that happened considering we were both sitting at the stop.
