Hi,
I’ve bought SparkFun LTE CAT M1/NB-IoT Shield - SARA-R4 (https://www.sparkfun.com/products/14997) with an holohram SIM card and I have tried the example code to register operators with Arduino as explained in the hookup guide (https://learn.sparkfun.com/tutorials/lt … 1542220466).
It detects only two operators that are not compatible with hologram SIM cards (TELUS and Bell).
I have tried putting the SIM card in my cellphone and it can easily detects the allowed operators (Rogers and Videotron).
I have also tried with another SIM card from my provider in the shield and I still detect the same operators (TELUS and Bell).
I am in Quebec City, Canada and from what I know and from the test I made, I should be able to detect all operators…
Any idea about that?
Thanks.
Francis.
