I want to connect my arduino to the internet via 4G. I tried it with an MKR-GSM 1400 but it didn't really work. So I think the quickest solution for me right now would be to buy a all-in-one data transfer unit; antenna, battery and everything else already included. But I don't really know what I should look for in this product class so that it's compatible with an Arduino. I found this product but I'm not too sure if it's compatible and maybe one knows a more compatible one?
