4G Dongle is a wireless router that enables customers to connect their PC, laptop, or smartphone via a broadband or Wi-Fi signal. They are small routers that can be easily carried around; for example, the 4G LTE WiFi B Dongle Stick, which works in areas where network coverage wireless is poor and provides an alternative for users who are unable to connect to the internet at their location. Now, 4G dongles have become a trend among Indian users, willing to invest in high-end devices like 4G LTE smartphones and tablets with the Android operating system.
