What is WisCellular ?
The WisCellular is a NB-IoT Arduino shield which is a upgraded version of WisLTE with global regulatory certification. I am very luck to the one of ten Betas selected for evaluating it before launching.

What are inside package?
I received a paper box with WisCellular shield, Type A to Micro B USB cable, a LTE antenna, a GPS antenna and a tape for fixing GPS antenna.
- WisCellular shield
- USB Cable
- Hologram global IoT SIM card
- QNavigator 1.4 link
In the first review I will not write any code or command. But we could still get a lot of information and test many functions of WisCellular . Let’s start!
Register Hologram SIM card
At first, please follow the tutorial to register your Hologram SIM card.
Install USB driver link
Download and click, continue and continue until the installation is finished.
Connect the WisCellular
- Connect WisCellular with a Windows PC via a Type A to Micro B USB cable. Click the PWRKEY of WisCellular. After a few second you will see the green light will on and meanwhile three virtual COM ports are detected in the “Device Manager”:
- Quectel USB AT Port – AT command port, it is the primier interface for testing;
- Quectel USB DM Port – Diagnose port, it is used for FWupgrade and catching log;
- Quectel USB NMEA Port – GNSS port, it is used for streaming GNSS data;
- Open QNavigator.
Select UMTS/HSPA even though BG96 only supports GPRS, since I want to test GNSS function. Then click Next and Start until the main interface is shown
Click the serial port icon to setup parameters
Select the AT port shown above. The other parameters are shown below
- Baudrate: 115200
- DatabBits: 8
- StopBits: 1
- Parity: None
- FlowCtrl: None
- Click “Connect to module”. The QNavigator will try to talk with BG96 via AT commands. You will get a not important warning message and at the same time different kinds of information are also requested and shown.
Do you have NB-IoT service nearby ?
I think the NB-IoT service is not supported every where in Germany. We could use a simple command to test whether the base station nearby has support of NB-IoT.
- Click “AT Command” in the sidebar and find the COPS command. Click “Send” button and wait a few seconds, BG96 will show the information of the base stations nearby. From the last number of each group, the services can be identified:
- 0 = GSM
- 8 = LTE Cat M1
- 9 = LTE Cat NB1
It is easy to see, in the area where I am living, there is currently no NB-IoT service :(.
Click “AT Command” in the sidebar. The system will select the right serial port for you. Then you can simply click the “Connect” button.
The GNSS function will be activated. After a about 1 minute the position information will be shown below.
