From a top-down perspective, the MiFi 6620L is compact and stylish; slightly larger than a credit card. From the side, however, the hotspot is nearly 0.75 inch thick. This is due to the high capacity 4,000 mAh Li-Ion battery on the inside. To put this in perspective, the iPhone 6’s battery is just slightly more than 1,800 mAh. The larger battery allows for this MIFI to be Novatel’s first juice pack, as well as a mobile hotspot. Overall, the hotspot isn’t exactly what one would refer to as “sleek,” but the size is certainly manageable.
On the side of the device there is a MicroUSB port, used for charging the device, and a separate USB A-Female port that is used to charge a mobile device such as a Tablet or phone. While unique, this set up does have a major flaw: the sliding door that exists between the two USB ports. As a result of this quirk, the device cannot be both charging itself, and your mobile device, at the same time. While this doesn’t seem like a big deal, the lack of the door could have made the MIFI6620L even more useful in that horrible situation when you forget to bring your charger adapter for your phone.
The MiFi 6620L is also very easy to navigate. Its LCD screen comes with three buttons used for changing settings and viewing the status of the mobile hotspot. You can also quickly find out its current Wi-Fi network’s name and password. The screen also displays an alert each time a new client connects to its Wi-Fi network. And each time you plug the MiFi into a computer via USB, the screen will ask whether you want to use it as a tether modem, or only for charging. While this is nothing new, the interface is easily accessable and something that consumers have come to expect. It’s nice to see Novatel didn’t try to do too much and complicate a system whose quality is based upon simplicity
Other than that, the MiFi includes common settings found in many home routers, such as port forwarding, port filtering, MAC Filtering, support for IPv6, a firewall and so on. Interestingly, however, it doesn’t allow for IP address reservation, where you can make a client always connect with the same IP address. This means you might need to change the settings of related features, such as port forwarding, once the IP is changed.
As a cellular device, the MiFi is unlocked and will accept SIM cards from other carriers. You will likely need to change the cellular settings before the device can connect to their networks, however. Technically, it supports all cellular standards in the world.
Finally, the MiFi comes with a terrific set of features for such a small device. There’s a simple parental control that allows for putting certain sites on blocked or allowed lists. After that you can select which connected clients are applied to which lists.
Another great feature is the built-in GPS. Supported Wi-Fi clients can automatically use the MiFi’s GPS feature. In my trial, the GPS features worked well, but only out in the open. As you would expect of something that talks directly to satellites, it was never able to find a GPS signal inside buildings.
