Me and my wife both have recently got the HTC Desire S and there is one thing that i noticed, if she texts me whilst i am underground, when i finally get reception i do not get the text until she texts me again (when i have reception), could this be a setting in the phone ( i have unchecked background data) or the network - i am on o2 (it was fine when we both had blackberries)

Did you use text messages with your blackberry or BBM?

combination of both - both would come as soon as i had reception

Strange why SMS would be effected just by changing phone...

I know on my iPhone on O2 I get text messages straight away as soon as i'm back in a area with a signal but then I also did with my SE and Nokia Symbian phones.

Not sure why the Desire S wouldn't.

Don't forget that SMS is not an instant messenger service, whilst nowadays we are used to them arriving within minutes they can take up to 7 days. (There is a message validity setting in most phones which is usually set to maximum - this tells the message centre how long to keep trying to deliver).

Nowadays most messages arrive within 24hours , even at busy times, indeed some providers terms and conditions say they will make. every effort to deliver the message within 24 hours.

I suspect what's happening is that when on the underground, you get brief periods of service. All this 'on and off' means that the handset isn't properly registered on the network and messages get stuck for a while until the phone changes cell or a call is made. This seems quite common with some handsets but never seems to happen with others.

Some networks too - I had this happen a lot when I was on O2 and still have it on giffgaff. Haven't had it happen to me on any other networks though.

Why not get Whatsapp?
