how to remove this problem?
why m getting BAD REQUEST or "Your client has issued a malformed or illegal request."
 

We are a manufacturer of modem, and distributor of Wavecom module for 10 years. We heard you have problem with sending data by XL. We hope you can tell me more and solve it together.

We have the capacity of desinging and making modem, so we also has the problem to do yours'.
