The Hologram eUICC SIM Card is a mix between legacy and new technology for cellular service for your project. Hologram’s eUICC SIMs enable profile switching capabilities so you can work with Hologram to dynamically change the subscriber profile of the SIM while the devices are in the field over-the-air. For those looking for IoT cellular service with no intentions on switching cellular carriers, this SIM card is also for you.
eUICC features are limited to certain modules at this point. This includes the u-blox SARA-R4 module used on our SparkFun LTE CAT M1/NB-IoT Shield - SARA-R4. For these situations, the functionality will that of a normal SIM with cellular service through Hologram. You won't be able to change carriers.
