APN is a important information when you want to access the cellular internet, we have build-in APN information in the software but the network carrier may change it.
First, open a web browser and go to http://cudy.net or http://192.168.10.1.
For details, please refer to How to log into the web interface of Cudy Router?
Then click General Settings->Cellular->APN.

Note:
1. The Username and Password are optional.
2. You can contact your internet carrier to get the correct APN value and Authentication Type of the SIM card.

“Hi, I have an LT12 LTE router. I can’t connect to the internet with a Vodafone Greece data SIM which works fine in my TP-LINK MR600. I have the APN settings as provided by Vodafone customer service and I have tried every possible combination of APN settings, nothing works. I have the latest 2.1.3 firmware. Other data sims (including Voda sims) have worked fine with my LT12. Please help.”

“I’ve sent 3 emails asking for help in connecting my LT 18 router to the internet using an Xfinity SIM card but have NOT received a response. The SIM card works in my MOFI4500 router but not in yours. I included a bin file of the diagnostic report.”
