I was up and running with my RAK5860 (BG77) using a hologram sim.
I was sending tcp data to both hologram cloud and our server.
While testing, i was connecting to Telus in Canada. This is the preffered Hologram network where in am located.
Then my sample of “native” TELUS IOT sims arrived, so i popped one in after making changes to the APN in my code. I got no service. I tried lot of changes, i reset the bg77 back to factory defaults. I started using Quectel Navigator for testing, rather than my app. Nothing worked.
So i decided to go back to Hologram sim. And the same. I cant get my app or QNavigator to get any service!
I done a bunch of searching, but cant find out how to deal handling SIM card changes and getting back on a network.
Any ideas what to try?
