What is the significance of keeping empty APN?

@akn

There isn’t a ‘significance’. it just means the unit will try to perform the initial LTE attach (or 3G data session) without an APN. If you don’t know the APN your SIM should be using it is the safest thing to do as more networks will reject an incorrect APN than no APN.
