Well, post the format that you receive an sms in. Is it one long string? Is in an object?
Post it.

Thanks for your response......
following is the format of sms.... -
AT+CMGR=2

+CMGR: "REC READ","121",,"07/04/18,15:26:01+00"
-
(1/2)Roam with Airtel at 56% reduced National roaming rates and no monthly rental. All local calls-Rs1.40/min, incoming calls-Rs1.75/min, STD calls-Rs2.40/mi

When you say "the 4th line" is all that a single string, with a line feed at the end of each line? I'd say, figure out whether the end of line is a carriage return, a line feed or a combination of both and do a split. For example - if it's a carriage return and line feed: Let's say your data is held in the string variable Data
Dim UsefulData As String = Data.Split(vbCrLf)(3)
If it's just a line feed:
Dim UsefulData As String = Data.Split(vbLf)(3)
Have you tried those?...

No problem, which worked? It's useful for other people to know should someone else search for a solution. I note that in many systems (UNIX for instance) that there is only a line feed (which I think is Chr(10) - or vbLF), but in Windows systems provide a carriage return and a line feed (as per the old typewriter) which is Chr(10) & Chr(13) ... or vbCrLf. Often when you're parsing text files, it's useful to remember that the text file may not have originally come from a Windows system, and as such, if your structure relies on an end of line, then you need to be aware of the differences.
