I am a university student so oversimplification would be very helpful and appreciated.
We are using SODAQ SARA R412 and we need to connect a SIM card from our local telecommunication provider “Du”, which supports an NB-IoT network.
Can you help explain the steps I’d need to accomplish a connection using the SIM card to the network?
With a few changed it can also be used for your provider.
You need to select the correct MNO Profile.
These are the option:
* Values for MNO profile (AT+UMNOPROF)
* • 0: Undefined
* • 1: SIM ICCID select
* • 2: AT&T
* • 3: Verizon
* • 4: Telstra
* • 5: T-Mobile US
* • 6: China Telecom
* • 8: Sprint
* • 19: Vodafone
* • 20: NTT DoCoMo
* • 21: Telus
* • 28: SoftBank
* • 31: Deutsche Telekom
* • 32: US Cellular
* • 39: SKT
* • 100: standard Europe
You can skip setting the bandmask.
You have to set the correct APN for your provider.
You can use the auto operator selection. If this does not work try the force operator method.
