I have a Samsung GT-I5500 (Europa) running Android 2.1.
Sending an SMS message to an off-phone will result in a notification saying 'message not sent'
It is never delivered even after the target phone is turned back on.
Message should be stored on network until it expires or is delivered.
I have eliminated network causes by trying the SIM in a non Android phone, which works as it should do.
I also tried a different network SIM in the phone, same problem.
I suspect the SMS 'message validity' field but cannot find a way to access it.
Anyone experienced this? Are there any solutions?
