Detect Hologram SIM card (vs other SIM cards)


Hi, we are rolling out Hologram SIM cards in a number of systems, and wondering if there is any way to detect a Hologram SIM is installed (vs Verizon, etc). This would allow us to automatically set the APN in software vs requiring a configuration parameter that needs to be set.



Hey @cbrake,

This is a bit of a tough one. I know that since 2015 all Hologram SIM cards start with 8944. Not sure about other carriers, but if they start with other numbers you could check the SIM number with at+ccid and derive your logic from there.
