has a GSM or LTE module

Hello. Device in your account has HD03 unit. It uses 2G&LTE modem.

Hi,

Thank you for your answer. 

I'm experiencing delays in the update of the GPS location in the map of the app as well on the website, so I wanted to make sure that it is 4G (LTE). I've Tele2 sim card and I've also an issue that the system calls me back if there is alarm but doesn't send sms in either cases of alarm or responses to sms commands. 

Hello. You should contact to your StarLine installer to check SMS-servisc work.
