Strange! I’ve just sent you an e-mail.

Hi Tibor, Did you succeed to connect? I want to use the Boron to.

Ah that’s a shame Good luck with finding solution.

Okay, my problem is fixed. I flashed the sequans modem again and I tested my code again. But it was still not working. I wiggled the cable of the antenna a bit and it connected to the network! I think the antenna of my gpy wasn’t connected properly or the antenna cable is broken or something.

Problem solved. It denpends on the sim card

May I suggest you also take a look at our central FAQ page for NB-IoT Roaming?

The NB-IoT service offering has started in all countries with pure NB-IoT SIM cards. In Germany, Austria and the Netherlands Multimode SIM option (NB-IoT, LTE-M, 2G and 3G) is supported.

Deutsche Telekom supports all current SIM formats, including the embedded SIM Form Factor (MFF). eSIM as of eUICC currently does not fit with the NB-IoT business model due to high costs. Instead, a more suitable option for NB-IoT use-cases is nuSIM, which is currently in launch preparation. Find out more about nuSIM.

Yes, NB-IoT always comes with a SIM card, as it features LTE-like security, which is based on standardization and specifications of 3GPP. A standardized SIM profile also allows international usage of NB-IoT on the networks of foreign mobile network operators as soon as roaming is agreed and deployed. NB-IoT is always SIM-based, but different form factors will be offered.

Hello Max, our network supports just one active PDP context per connection. Best regards

Hi, what kind of SIM are you using? I’m asking because our m2m/IoT SIMs usually come with PIN disabled. For this reason, PIN handling is not included in our HW-library. Unfortunately, the module you are using does not support any management of facility locks, other than entering the PIN when the radio is turned. To proceed you should deactivate the PIN on the SIM on a different device. You can either try a smartphone or a different module which supports the management of facility locks. The required AT-commands for this are: AT+CLCK=“SC”,2 # Query status of SIM lock +CLCK: 0 # SIM is unlocked (1 would be locked) AT+CLCK=“SC”,0,“1234” # Remove SIM lock (for PIN 1234) Best regards
