This is the TP-Link AC1200 SIM-free home router (Archer MR600/A). For those who don't have or can't get a fixed-line connection, this "plug-and-play" Wi-Fi router allows you to insert your SIM card, eliminating the need for troublesome installation, and provides high-speed communication of up to 867Mbps. While the specifications state that it can be used with SIM cards from domestic carriers, some may not be compatible depending on the contract (plan). Also, the communication speed and radio wave strength will vary depending on the carrier and the location of installation. Used for about 10 days after purchase in December 2025. Includes the box, quick start guide, AC adapter, and LAN cable. This product has a 3-year warranty, so a receipt or invoice (from Amazon) as proof of purchase can be included. Personal information will be masked. If you would like this, please comment at the time of purchase indicating which you prefer.
