Remarks
The WDP layer sends the WCMP_MESSAGETOOBIG message if an incoming primitive exceeds its limit. However, the WDP Short Message Service (SMS) provider will also issue this WCMP message directly if a multipart message is bigger than the provider can handle.
Also note that the WDP layer, not the GSM WCMP provider, sends replies to WCMP_ECHOREQUEST messages.
