I have an update on this.... Having dealt with the usual Three support yest
erday they said they will call back last night. Anyway, to be fair to them
, they escalated up to the next level of support and I spoke with their eng
ineer who I must say was very good. Knowledgeable and good troubleshooting
We were able to find a couple of messages that were sent but not received.
He was able to check the logs their side and oddly, it seems the messages
were received by Three and for some reason they thought were delivered to t
he handset correctly but were not. At the moment it is looking like a prob
lem at their end. He check the set-up their end and got me to enter some m
agic numbers into the handset to clear all call forwarding, barring etc. fe
atures. We are then giving it a day to see if the problem still exists and
if we can give an example of a failed one he will escalate it to the next
level for resolution.
Not sure whether it is related but both examples we found, the sender was o
So now we have these friends sending a few texts to my wife (and confirming
texts to me) throughout the day to see if we can replicate the problem.
Will keep you posted...
