I owned the
Novatel MiFi 2200 Mobile Wi-Fi Modem (Verizon Wireless) for more than 2 years. After my contract ended, I kept using it because it worked so darn well. Working well for me means that when I turn it on it connects to both the Verizon network as well as my connected devices every time, all over the Washington DC area, and other parts of the country when I traveled. The 2200 did this, consistently.
About a year ago, I started looking at a replacement for the 2200. I didn't like what I saw. The reviews were alarming. Yes, some of these newer devices were supposedly faster at "4G," but some of the reviews of the newer models said they were unreliable, in that they didn't consistently work well. For me, there was no point in upgrading the device to a faster speed if it didn't work all the time.
I am really glad I waited. I've had this device, the 4620L Jetpack, for almost 2 months now. It has worked every time I have turned it on. The connections are really quick. And, the speed at 4G is fantastic.
One caveat: the plan I had under 3G with the 2200 was no longer offered by Verizon, and the cheapest plan for the 4620L is $15 more a month, with a higher monthly data use allowance. I don't use any more data than I did before, so I am effectively paying more each month, but at the higher speeds it is worth it for me.
In sum, if you are upgrading you will like the faster speeds. If you are new to the MiFi product line, you will appreciate that it works as described.
****UPDATE, July 2, 2012****
As you may know, the Washington, DC area just got through a very bad storm and many people have been without power for days. I myself lost power for 2 days. During this time, neither my Cable company's internet service worked, and nor did the data service for my iPhone, provided by the major competitor to Verizon. The Verizon Jetpack, on the other hand, worked consistently during this time allowing me to stay connected to the internet to check on the status of power restoration, as well as do other critical things.
The battery life of the Jetpack was impressive, but it certainly did not last the entire time my power was out. So, in addition to charging the Jetpack while driving, I used the
Brunton Inspire Portable Power to keep it charged.
****UPDATE, Dec 5, 2012****
Since I have purchased this, I have had a chance to use other "hotspots." For exmaple, I purchased another brand for my mother to use in her assisted living facility. One thing that sets this product, the Novatel MiFi, apart is its smaller size. Its not apparant when shopping for them, but some other models are really quite large. The nice thing about the Novatel MiFi is that it is small and light weight, so you can slip it in your pocket and not really notice its there. By comparison, the model I got for my mother (offered by a different provider) is large and heavy.
Also, just thought I would mention that this Novatel MiFi is still going strong. One of the nice things is that every couple months Verizon sends a firmware update, so I know that are actively supporting it.
