Bests & Worsts Reviews from Amazon

Wow.!!!! What a difference in performance from the 5510L.! The 55 would never seem to get above 3 bars, and by the afternoon it would be down to 1 bar, maybe 2....with abysmal download speed and constant disconnects..! This new 6620L has 4 bars without an external antenna and my speed tests have shown between 30-35 megabytes downloads consistently.! Verizon has a $50 rebate so the unit ended up costing $49...with my month to month plan. Edit: 9/1/15 This thing has become an incredible data hog. After using it for the 1st 3 months, it telling me I'm using vast amounts of data.! And by vast amounts I'm talkin over 4 Gigs in just 2 hours of use.! I don't download anything, I have my udates turner off, In don't watch videos, and I've even turned off the video in my Forefox browser.! Yet, it's claiming I've downloaded the equivelent of Windos 10 plus a gigabyte.!! That's impossible.! I've read many, many posts about this crazy data overages, which only started to happen when I switched my data plan from 5 gigs to 10 gigs. All of a sudden I'm going over every month.! That is unacceptable!!! Verizon customer service has been useless, as have been their tech support.! They're basically blaming me for the overages, and even when I told them that on my 5 gig plan I never used it all in a month and that my sufing habits were identical, they are still going to charge me. That' over $100.00 a month for just surfung the web and reading newspapers. Of all the posts i've read about this, only one person found a service tech who knew about the problem and remedied his situation. It turned out to be a bad sim card. He replaced itn and has not had the problem since. I'm going to try that tomorrow and see what happens. I'll keep you all posted on my success. EDIT: 9/15/15 Well after visiting the Verizon Store and, not only speaking with them, but also with a service tech on the phone while in the store, Verizon claims all my usage is valid.! Turns out, ...they have no more ability to see your usage than you can find out yourself online. They refuse to admit that there's any problem with overages of data usage, and claim they've not heard of this problem before. I guess they're not tech savy enpough to use Google.!!! I found pages of complaints of being charged for data, that MANY HAVE CLAIMED THEY NEVER USED and all, to a Person.....got the same BS Answer. "Never heard of it before".. and.. "all your usage is legitiment".! Well, after weeks of research I found one person who posted an answer he got from a knowledgeable service tech, who told him he'd heard of the problem and, that itwas traced to a Bad Sim Card.! He was told to replace nit and has since had no more data overages. I did the same 2 weeks ago and.....No More Date Overages so for. It's back to my regular monthly usage of 5-6 gigs.! Hope this sim card fix helps others.! Cheers, VB Final Edit: Well, here it is at the end of my billing cycle annnnnd.......my data overages are nonexistent.! I seem to be,....for the moment back to normal usage. Since I changed the Sim card,....surfing the web this last month has been normal. No overage charges. Replacing the Sim card seems to have cured the data overage usage. Cheers.
