I'm using an A6 GSM module to connect a microcontroller to a server over the Internet. I noticed that I have to manually configure the APN settings for each SIM card I use.

So, is it possible to automatically configure these settings? How does a mobile phone do it?

I found out that it is not possible. Phones have a database with APN settings from many (but not all) providers. A solution could be to use a carrier agnostic network: https://hologram.io.
