im a heavy sms user, lets say i sms 10 days, at least 6 days there are delay..

Once I received a sms 7 hours late from my friend. It said ' Im at the meeting point'. I was shocked when I received the message cause I though I had forgotten a meeting. I called and realized that It was a very long sms delay. he sent the message at around 8 am, I received it at about 4 pm.
Im 016, he is 012, not sure whos fault was it.

Edit, forgot 012 016 no point d. He is using Maxis and I am using Digi.

I guess so because they say by switching off the phone for some period of time, the line can reset by itself. I normally turn if off for a good 15 minutes.

Somehow that is pretty normal. Mine goes like message sent but recipient didn't receive.
