Ussd Problem

Hi
I’m having a problem with sending a ussd that is just a sim number and do not include the * and #.

Using the following commands ..

 :interface lte at-chat lte1 input="AT+CUSD=1,\"*123*5#\",15" wait=yes (working fine)

Then a reply again with

:interface lte at-chat lte1 input="AT+CUSD=1,\"5\",15" wait=yes (working fine)

And then the problem

:interface lte at-chat lte1 input="AT+CUSD=1,\"0523451232\",15" wait=yes (Network reply that it is not a cell number)

The number is correct and work on phone.

Thank you.
