I am trying to connect my MKR NB 1500 to google IoT Core, however i am experiencing the same problems found in this topic: Trouble getting MKR NB1500 working with Google Core IoT - MKR Family / MKRNB1500 - Arduino Forum
I was wondering if anyone found a solution?
I also did read that people had more succes connecting to the azure IoT Hub, which i will be trying now.
I ran into the same problem of not being able to connect with Google IoT, Azure, and AWS. I did finally find the root cause and a solution about 5 months ago. The root cause is that MKR NB 1500 ships with outdated firmware for the Ublox SARA modem. The procedure to fix this may seem a bit complicated, but trust me it is not too bad. Read through the thread below carefully several times and it takes you through the process step by step. There are several things you need to download but all the instructions and locations to get that stuff are in the thread. I will tell you upfront so that it's not a surprise when you get to the thread, you have to solder a USB cable directly to the modem pins on the MKR NB 1500. For me, that was the scariest part, but it turned out to not be too bad.
Here's the good news- once I did that I was able to connect to AWS in a snap. Everything I had been banging my head on the wall about was fixed. I have not tried Google or Azure since then, but I'd bet this will solve the issues for those platforms too.
Good luck!

Thank you for this clarifying answer!
I came along that forum post a while ago and was also scared to solder an USB cable to the modem pins and therefore did not do it.
I did however update the firmware from L0.05.06,A.02.00 to L0.05.08,A.02.04 by following a guide that didn't require soldering. With soldering you upgrade to A.02.19.
This week i will be testing Azure to see if A.02.04 is enough to succesfully connect to it, otherwise i will be following the instruction in the given thread.
1 more question: Do you know where you can buy a module with updated firmware? Or found any good alternatives for this board?
