Hello,
Hope you are doing well,

format for example to concatenate the message UDH:

first part: 0700035502016000 -- 07 UDH length
second part: 050003550202 -- 05 UDH length

6000 is the added one.

Thank you

Dear Admin,

Is there a way to send a custom UserDataHeader as full data without passing by the DLL parsing part or changing the DLL source code?
The main problem that I have concatenated messages with different UDH length, for example part 1: length 5, part 2: length:3.

Thank you
