Sounds odd.
Was it always like that?
Are the delayed texts coming from a particular network or any network at all?
Could you get somebody to test with delivery notifications switched on (if available) and see how these compare to you getting the message?
Could you test using another unlocked handset?
Maybe 48 support can advise?
