FiPy - connecting and sending data over CAT-M1

[securigy]

Re: GPy with Hologram.io SIM

I am running this example code that I found here (from April 20, 2018) on FiPy.
When my LTE antenna is residing on my desk the LTE modem won't attach for a long time (3-5 minutes), while the reason is alternating between 0 and 4. Then when it does, the lte.connect(sid=3) fails.
Now, when I pickup LTE antenna with my hand and am holding it LTE modem attaches within 5 sec, and yet lte.connect(sid=3) fails.

What am I doing wrong? Do I need to change the side value?
