Delay in sending SMS messages

I now have three zones active, a PIR, vibration sensor and a reed switch.   When I trigger all three zones at around the same time, I noticed that the first alarm SMS gets sent straight away, but the additional ones take some minutes to get through.  I thought at first it was just my mobile network but actually the Gatway seems to delay sending them.  I've included some debug below with the approximate time stamps, according to the Gateway clock.
