Sim card dual band router
If your home network needs only wireless Wifi, not wired, it is very economical and convenient to buy a machine that can be used with a SIM card. After all, the all-you-can-eat network on mobile phones nowadays is better than anything else. It’s much cheaper to apply for Chunghwa Telecom’s fixed network, and every time the contract expires, you can also exchange it for various home appliances according to the current demand, which is also a good way!
