when I am getting it with Request.QueryString["sms"] its removing + sign

You need to URL encode the parameters (or rather, the whole URL).

The + sign is the encoded version of a space, and therefore need URL Encoding to preserve it.

In fact, you need to URL Encode any URL passed parameters, make a note for the future!

Encode + sign then add it to your query string
