I'm on a military base here in Afghanistan and many soldiers and civilians seem to like and use this device. I have an iPad with a data plan to the local carrier, so I fail to see the reason to buy this thing, myself. I would need to buy yet another sim card, pay to load it, then surf the web on it? I already do the same thing on my iPad with the same sim.

Or let's say you go to Mexico or Europe and your US phone is CDMA: no CDMA networks there. You can still use Wi-fi connections if you happen to run into one, but it is not always the case (at Frankfurt airport you get 60 minutes of wi-fi for free, but what if your layover is 8 hours, or try to find free wi-fi in a London airport. If you bring this you can buy a local SIM card and then provide your own wi-fi hotspot for your phone, laptop, tablet. Of course you'll have to pay for the SIM and a data plan to go with it.

You should put your sim-card into this router, so it broadcasts internet through wifi. It can be used instead of USB-stick 3G modem and share internet for several devices. Locked device can be locked to some providers and work only with their sim-card, unlocked version is free of this restrictions.

You put your 3G card in the Huawei and it transmits Wi-Fi to the Wi-Fi devices (computer, ipad, etc.) and you don't have to have a router and standard Wi-Fi connection...the device can be used anywhere you get a 3G signal...driving in your car and you get 3G signal, you can use your Wi-Fi on your computer for internet...I use mine in Costa Rica, all phones are unlocked...don't know how it would work with the chips that go into locked phones in the USA...should work...

You don't need this device if you have access to WiFi. You don't need this device if your cell phone permits you to 'tether' other devices. In places where you have No WiFi, but where cell phone coverage, 3G/4G is available, and if your cell phone does not permit tethering, and if you have a device like a tablet or a laptop PC without a dongle, ....with which you want to access the internet, then this device is handy. It can serve multiple devices simultaneously. Of course, you need to install a sim chip with data service from the cell phone provider of your choice.

Actually, not sure why one would use it in the US. Those of us who travel outside of US, however, do need them. In Asia, they say you have wi-fi in your room... only you don't. Ever. In Europe, it says the hotel has wi-fi... but when you get there it's only in the lobby. I paid international roaming in the Narata airport at the free wi-si hotspot under the sign designating that workstation as the free wi-fi hotspot. Outside the US, what they say they have and what they have usually contradict each other. Which is why I'm getting so frustrated with Americans asking if it works here.

Disregard my last answer a second ago, as was answered from another person this booster is a SINGLE user booster. What your after is the Wilson 801201 Dual Band Wireless Mobile Amplifier. This will allow multiple users to connect on the 2g 3g (not 4g lte) bands. The amount of users is based on outside signal factors, the device itself has no limit.

The one for $295 which is manufacturers reference #460102 is a newer later model that is supposed to be the only one marketed now. It works just as well as the earlier version that is $349. The newer one may require an adaptor #971119 to connect to some antennas. I have one and it works great, just understand that it will boost the 3G signal. If that is what you are looking for, it will work great!

Mark, No need for AT&T...; The device looks for nearby WIFI signals such as at your local library, McDonalds, apartments, ect. Some people use them at campgrounds / hotels where WIFI is provided so they can work from their trailer or car rather than go in and eat at the place... It will also work on your neighbors WIFI if it is unlocked. You are basically using their signal. The range is limited depending on the straight line theory. Some of these devices can go to a 1/2 mile or more... Read others comments as to the range and problems they have encountered. This device is fragile, so don't bang it around....

A Range Extender repeats an existing wireless signal wirelessly. An Access Point has to be hardwired into the source it is trying to repeat.

this is a 4g device. that means that it contains the necessary hardware to get, at best, 4g signal. if you are not in a 4g area you will get 3g. if you are not in a 3g area you will get 2g(yes that exists, but i am unsure if 1g exists). if you are not in a 2g area....... you probably dont need a smart phone. in any case, this device will get 4g data if it is available. verison has great 4g coverage, but not perfect so the mention of 3g was probably to cover all the bases and tell you exactly what you are buying.

What would be the purpose for doing that? I can only think that maybe the modem and the router are so far apart (over 300 feet) that you need a switch to repeat the signal between them? Does the wireless router have multiple switch ports? You can just chain this switch to a switch port (not the WAN port) on a router to add more ports/jacks for local devices (although even that occupies two ports - one from the router, and one from this extra switch).

You can only access the device when it has a signal. If there is no signal you get an error message that the device cannot be located. And you only get it last location.

Not 100% sure what you're asking, but i think i understand . so I will say that me and my daughters are each paired to them from different devices and it works fine. Whoever is in nearest range pairs first then locks in. The others, while paired, wont connect until i disconnect. You can pair as many as you want, but only connect one at a time.

It has it's own built in wifi signal it emits to your device and that's how you connect to it. Honestly, I could never get it to work even though I could get my device to see it. I just plus it in and use it like a flash drive now.

do not know what you mean "...not just copied?" you will only view what the input signal is... this is only a splitter, sending the same signal to two different receivers.

Actually i googled it a lot before doing the first post here but i think that this item here at amazon doesn´t has especified the 3G frequency, that´s why i asked...but i already bought it :) thanks

Yes. The device accepts signals and is simply amplifying them for your cell phone. Your phone should be close as you use this device for best data speeds. It is important also to note that several devices may use this at the same time, however using more than one phone will slow throughput. Very important! Be sure the device matches the frequencies your carrier uses.

This would be very dissappointing (and a rather stupid move on Linksys' part). Netgear has long had additional handsets available for their similar (internally identical) phone. Anyone evaluating these 2 phones should take this news as a reason to drop the CIT400 from the running. I have 2 CIT400's - one for each house and they work great - at one stage I had the 2 handsets linked to one base station and that worked fine. I have bought the Netgear phone with it's extra handset and should receive it in a few days. If it works out OK then I think I will buy another 1-2 handsets for the netgear and use the 2 CIT400 handsets in the other house (and have a spare base station).

Why would you want to ? the whole idea is wireless placement ! lol, and you can pair as many as you like to your device as long as they are within reach of your device's signal !

Its related to the GSM bands that the device supports. Some are quad band, some,only support 3.

This is a old model and when it was 1st released that is what nokia informed. Meaning, at the time of it's 1st release, the 4g update wasn't there and had to wait become available from Nokia software updates. That is why they terms as over the Air. Now these must already be in the market and when you get the device, you can update the software which will implement the 4g option to compatible with the said network bands. Thank you. KICKmobiles
