What is local access?

mFLASH transmits communications either directly via the classic mobile network or through an Internet connection.

Local access transmits them by a classic mobile (non-Internet) connection. The local access is particularly advantageous if you have a package that includes free calls to national landlines. If this is the case, you will not be billed by your mobile operator. 

The application uses the local access by default. This can be modified in the application's settings.
