Bests & Worsts Reviews from Amazon

You can ignore the meaningless “AT&T Network-Ready” statement. This is an unlocked device and will work with other UMTS and LTE networks in the supported frequency bands. I inserted a T-Mobile SIM card and got connected without any help. The modem has a simple and elegant web interface; I think it’s nicer than what you typically get in NETGEAR routers. (HTTPS is not supported, unfortunately.) Setup is very easy and takes only a few minutes, assuming you understand what you’re trying to do. The device can operate in two modes: router (default) and bridge. The router functionality is very basic. It can act as a DHCP server (with no address reservations) and provide NAT. It also can support a DMZ host, static port forwarding, and port filtering (blacklist or whitelist). There is no mention of UPnP in the manual or the web interface, so I assume it’s not supported, but I didn’t test it. The bridge mode allows you to connect the modem to a real router, just like you would connect a cable modem. I suppose this is what most people will do, myself included. You won’t find any IPv6 settings, but it is supported in both the router and bridge modes. You may need to enable it in the APN profile though. In my case, only IPv4 was enabled by default. Speaking of APN profiles, one should be configured automatically when you insert a SIM card, and you can edit them. The modem can send and receive (but not forward) SMS messages. You compose and read them via the web interface. You can have text alerts sent to up to three numbers when it approaches and/or exceeds a usage threshold for the current billing cycle, as well as when a firmware update is available. The bottom line is: considering its functionality and ease of use, this device exceeded my expectations.
