wrong APN settings works great

Question

This question is a duplicate of wrong apn But none have answered. So am asking again. How come a wrong APN settings in both airtel and vodafone end up working great with no errors. I can able to connect with the internet using random names given in the APN settings. Did every network operator assign a default APN if the requested APN is wrong?

Answer 1

It is because they have already have an APN correction system. In this case actually you dont need to put any APN in, it also will work fine.

Not all operator have this feature. So, you have to becareful if you are changing operator, it might not work.
