Inreach SMS not working with CLARO ARGENTINA Carrier

Hi, I’m from Argentina and I have an Inreach Mini. They are 3 major carriers in Argentina. Claro, Movistar and Personal. 
I’ve tried sending messages from my Inreach with mixed success:

Emails: works ok.
Movistar SMS: works ok, including replies. 
Claro SMS: doesn’t work. I even tried disabling links but still doesn’t work. 
Personal SMS: haven’t tried it yet.

The problem is that everyone in my family uses Claro, so in order for my Inreach to be useful beyond the SOS capability, I need Garmin to somehow fix this. The funny thing is that Claro is one of the biggest Carrier in the Americas, and they even sell Inreach Mini in their online store in Mexico. But somehow they are blocking the incoming messages in Argentina. 

Hope this get solved soon.
