I tried one more MVNO sim - this time from US Mobile (which had even more data per month than SimpleMobile).Username wrote: ↑Sun Jan 24, 2021 8:59 amThank you for your reply. My personal mobile phone sim is also a SimpleMobile, and it works when I go to my parents home....which is the source of my confusion . I haven't tried my personal sim into the LBR20 yet, that might be an interesting test but that prolly won't help me understand the issue with the current sim. Per your advice, I may end up trying a first-party sim instead of simplemobile.
This time the sim worked both at my house, and at my parents house which is 20 miles away. It worked like a charm. Now my parents have internet and are also an echo dot instead of a computer.
I'm not really sure why US Mobile worked but the SimpleMobile did not (recall that the SimpleMobile worked at my house but not theirs). That pretty much ends my issue for now. Thanks for this site, and this thread. Good stuff here.
