This is an Airtel 4G hotspot1. It takes cell service and turns it into WiFi. This particular device is only compatible with the Airtel network in India. But everyone in Laos uses it to connect their phones to the internet. We bought one from a street electronics vendor in Luang Prabang. They buy them in bulk from the manufacturer in China, and then open them up and change a firmware setting in the software to unlock them. That way, any GSM SIM card will work.
