Text Messages - delay in getting through

[Anonymous]

Does anyone know why text messages sent between iPhones all using the O2 network are often delivered hours or even days late?

It can't be reception, because a group message sent to 3 people in the same road/office and 2 get it straightaway and the other gets it the next day or not at all?  

This is not a single occurrence.  We are now so wary of messages not gettig through that we are now asking the recipient to acknowledge receipt!  

It is also curious that I can have my phone sitting on my desk yet then receive an ansaphone alert when it didnt even ring.  Could this be a way od O2 generating income now that we have to pay for ansaphone messages?
