For now there are limited 5G modules out there, and we are limited to test. We are currently under discuss with a Operator company in China. We may have a 5G module released on our page(not 100% sure yet). Please stay tuned to this.
For your case, I suggest to use 4G module for now if there is no urgent needs
But if you want to use the Module in JAPAN, then you will need this version: EM06-J. This is not listed on the website but we are able to get them and they all have the same specs. Only differences are the region to use.
Fun fact, the CPU never actually sees the SIM card. SIM is wired directly to the m.2 slot. The WWAN card sees the SIM, the CPU sees the WWAN card (using USB).
In general, I don’t know much about these technologies. The other day I could not even establish the Internet for myself and asked a friend about it, I did not even know where to call, to which company. And my best friend showed this company aerial fiber . I immediately called there, asked everything, and literally a few days later they already installed the Internet and installed a new router. By the way, I also put television on my home and I really like it. Now I live in a small town alone, and I have one of the fastest internet connections, and I am happy about it
