Hello everyone,

We have created a system with a MangoH Yellow card to send a measurements on Octave.  
We’re in France, the system works, and we need to send it to another country (first to New Zealand, but in the future we’ll send it to other countries).  
Will the system continue to work, or do we need to modify the configuration for each country?  
If so, how do we change it?

Thanks in advance

What sim card are you using?

Here says you need to set the APN

Hi jyijyi,

Thank you for your reply.  
We use the Sim card integrated in the MangoH.

then you might need to try if that SIM can register in other countries (I believe it should work in New Zeland, but you better double confirm with field test)
