3G module

— wireless communication module based on mobile networks of the third generation (3G). In readers, it is used to access the Internet, primarily for the purpose of downloading content. Usually, to connect to a 3G network, you need to purchase a SIM card from a mobile operator, and network use is paid, but there are exceptions — in particular, some Amazon Kindle models provide free access to 3G networks.
