10 This configure instruction is for Dragino NB-IoT models with -NB or -NS suffix, for example DDS75-NB. These models use the same NB-IoT Module **[[BC660K-GL>>https://www.quectel.com/product/lpwa-bc660k-gl-nb2]]** and has the same software structure. The have the same configure instruction to different IoT servers. Use can follow the instruction here to see how to configure to connect to those servers.

16 To attache NB-IoT sensors to NB-IoT Network, You need to:
17
18 1. Get a NB-IoT SIM card from Service Provider. (Not the same as the SIM card we use in mobile phone)
19 1. Insert the SIM card to Sensor
20 1. [[Configure APN>>http://wiki.dragino.com/xwiki/bin/view/Main/How%20to%20configure%20APN%20in%20the%20node/]] in the sensor (% class="mark" %)(补充 APN 指令(%%))

24 After doing above, the NB-IoT Sensors should be able to attach to NB-IoT network .
