Do you have a roadmap / timeline to enable LTE-M connectivity on the Orange network in France?
Have you tried it? It might work.
It looks like Hologram does have a relationship with Orange in France per https://hologram.io/pricing/coverage/ In many countries CAT-M1 works as long as hologram has 4G with a carrier that offers Cat-M1. Not true for NB-IoT though
I have tried. It works with dedicated LTE-M Orange SIM cards but not with the Hologram SIM.
