When improving internet connectivity, you may wonder whether a WiFi extender or a SIM card router is the better choice. A WiFi extender, like the TP-Link WiFi extender, helps boost signals in areas with weak coverage, making it ideal for large homes and offices. On the other hand, a SIM router provides an independent internet connection using mobile networks, perfect for travel, remote locations, or as a backup internet solution. If your home has a strong primary WiFi connection but suffers from dead zones, a TP-Link extender is the way to go. However, if you need a standalone internet source, a SIM card router is a more flexible option.
