Tracker 403B
Work in GPRS/2G Mode. On the manual link (https://cdn.osabana.com/zumitek/documentos/433.pdf), it mentions 4G (B1/B2/B3/B4/B5/B7/B8/B12/B17/B20/B40) and 2G (1900/1800/900/850 MHz). I wrote on skype but they don't answer.
Mario, have you send the ip command?
@Anton, thats the reason i mentioned it. Coban states on the product page: GPS vehicle tracker GPS-403B 4G LTE
But at the details on that page: Detailed description:
