Code: Select allGET /testurl/sample.php?deviceid=5444541 HTTP/1.1Host: 54.251.98.159

You are missing "\r\n" between "HTTP/1.1" and "Host: 54.251.98.159" and also missing the "\r\n\r\n" at the end.
Using interactive PUTTY to try that out could be problematic with AT firmware.
Better try using python script, or simply forget about AT firmware and use better firmware such Arduino.
