Hi there !
Asked this question to the support team, but they still not finded the solution, so I'm asking it here, you had maybe the same problem by the past
.
I'm trying to configure an SMS Channel on ACS. I followed the documentation tutorial and created a new SMPP Generic External Account with information gave by my SMS provider.
When I Saved, no SMS option appeared. Even in the Homepage with the shortcut "Send an SMS" as you can see:

When I'm trying to create a marketing activity (Marketing Activity > Create Button), I don't have the SMS option :

It seems that the SMS channel isn't activated (but it is ACTIVATED on the external account...)
Do you already saw that issue ?
Could someone help me to have this new SMS channel ?
Thanks by advance,
Regards,
