I just recently installed a GL-inet Spitz AX and Peplink 42G antenna into my motorhome and have been very happy with them. I was very pleased when I saw that GL-inet added support for eSIM cards and was finally able to test this today. Somehow the eSIM cards were out of stock from store-eu.gl-inet.com so I ordered it directly from eiotclub.com
I used eSIM from orange.fr in Estonia and it works flawlessly
It does receive wifi signals too. I can easily access the systems running in my car even hundred meters away. And I can connect to public wifis and use their data instead.
