What steps do I need to take to use my own SIM card?
SIM card requirement:
- Mini-sized SIM (most common SIM card type with the dimensions of 15x25mm)
- Unlocked PIN.
The CheckFox device supports 3G/Edge GSM at these frequencies
- @UMTS 800/850/900/1900/2100 MHz
- @GSM 850/900/1800/1900MHz
The Quectel UG96 modem is used in the device.
The data transferred via GSM is one hundred bytes per measurement plus overhead, so you don’t need huge data plans. If you do 1000 measurements per month you need a 1MB data plan.
You can insert the SIM card if you unscrew the device and open it.
If needed the IMEI can be found in Service Menu - About.
Change the APN connectivity setting in Service Menu - Settings
