First, this switch does not require remote operation. It is a Failover feature. When there is no signal from the primary SIM card, the device will automatically switch to the backup SIM card. To prevent the backup SIM card from overloading, it can also be set to automatically switch back to the primary SIM card.
Secondly, Spitz AX is designed for RV scenarios, unlike Mudi. That means the device is not on the desktop and not in the bag. So it’s not as easy to change SIM cards.
Sorry, I wasn’t clear enough. I should have added after “It does not work with two SIM cards at the same time like a cellular phone.” that the Spitz AX can only activate one SIM card at a time and keep the other one as a backup.
There is a description on the product page, but it’s really not clear enough. We will try to improve it.
eSIM is also our goal. It is not a problem in terms of hardware, the main difficulty is to support operators around the world. We are looking for a solution.
IMEI is the identifier for the modem. The GL-X3000 has two SIM slots, but only a single modem. Essentially if you lose signal from one carrier’s SIM, GL-iNet have implemented a failover system where the same modem will then read the second SIM card and connect to that carrier.
One modem=One IMEI, really you can have as many SIM slots as you’re willing to solder and trace on a circuit board, but the number of actual connections is limited by the number of modems/radios.
Understood. Allow me to reframe my question: Is it possible to automatically change the modem’s IMEI based on the slot number that is in use? I understand that it is possible to change the IMEI via some sort of command, correct?
There is only one radio/modem and at present the code that handles failover and failback between the SIM slots has no facility to change the IMEI during slot switching. You could turn OFF the GUI features and hack something together yourself. A cron job that checks if WAN is reachable every x mins and if not reachable take radio offline, fix the broken IMEI to correct value, put radio back on. That sort of thing. Generally manufacturers will not produce that for you in GUI as they would face backlash from network operators etc.
