@afzal_m Particle Boron is based of SARA-R4 series Size-optimized LTE Cat M1 / NB1 / GPRS modules. They seem to be working in Germany so I don’t see any reason why it shouldn’t work in the Netherlands.

Hello,

I’m trying to connect my particle boron to the particle network using this guide: https://community.particle.io/t/howto-nb-iot-with-boron-lte-in-germany-telekom/52354/15

So far without success. Could there be something hindering the connection to the particle network?

When I do AT+COPS=1,2,“20416” it returns a timeout. What could be the reason?

I would like some advice.
