While Tianjie (often branded under names like Tianjie or 4G WiFi Tianjie ) isn’t as massive as TP-Link or Netgear, these little 4G routers are popular for travel, RVs, and rural areas because they are cheap and functional. The bad news? Official PDF manuals can be hard to find on generic websites.

Happy surfing! 📶
