Huawei E5577Cs-321 4G LTE Mobile WiFi Hotspot (4G LTE in Europe, Asia, Middle East, Africa & 3G globally) Unlocked/OEM/ORIGINAL from Huawei WITHOUT CARRIER LOGO (White)

I am generally okay with this product as it works to give me usable internet on the go and at home. I have two complaints though, battery life and network reception. If not plugged in, the battery life is only a few hours of continuous use so if Im traveling, I take an external charger or its plugged into my laptop. As far as the reception goes, what I get directly on my phone (not connected to the wifi pod) is always considerably higher than what I get when connected to the pod; this is true for indoors or even outdoors standing within clear site of cell towers. Now Im back on Amazon looking for the antenna that can be purchased separately and plugged into it to improve connection but cant find info on it online...

I bought this so I could use my iPhone in France and keep my US telephone number by using WIFI calling. And avoid the $10/day Verizon charge for international service. And it is working. Like others mentioned, the battery doesnt last long. I am going to buy a portable battery charger to keep it running more than 4-5 hours. And it took me a while to figure out how to get started with it. The Quick Start guide it comes with is useless and the support I found online assumed a level of tech & SIM card savvy that was beyond mine. It really could use an Idiots Guide so, if you decide to buy this, this may help get you started.... First about the SIM card, in case this is your first time with one.... A SIM card is what you will need to install in your mobile wifi device to get phone / internet service from a local provider. I got my SIM card from a Tabac (smoke shop). The card itself is free. But then you buy credits for $5, $10, $20 or whatever which you will add to your card. As I dont speak french, I am unfortunately still trying to figure out how to add the credits I bought from the Tabac to my SIM, so I then went to the website of the Telecom company the SIM card was from, LEBARA. That site can be translated into english. Once there, I created a LEBARA account using the numbers on the back of the envelope the SIM card came in. The shorter number No de appel is the SIM card phone number. The long number is its registration number. Once I had an account, I went ahead and bought another $10 credit online to get my SIM card charged until I can I figure out how to use the credits I got from the tabac. 3 hours into the day I had used up my initial $10 credit which sadly only bought me less than 300 MB of data. I then realized the $30 monthly plan (20G data + 2hrs intnl calling) was much, much, much more cost effective. No contract so as soon as I signed up for it, I turned off the monthly renewal. There was definitely a learning curve getting started. Hopefully you wont waste the $20 I did. But Im still ahead of the game vs. using my US Verizon plan. To get started with your mobile wifi device, charge it using the USB cord provided. Then to install the SIM card, remove the back of the device and the battery. Pop the card off of the larger credit card sized board, keeping the rectangle with the clipped corner / adaptor attached to the tiny SIM. Slide the card under the little gold band on the SIM slot to hold it in. (The Quick Start guide will show you which SIM port to use. Thats about all its good for. ) Download the Huawei HiLink app on your smart phone. Open it. Turn on the mobile wifi device. Go to your smart phones settings / wifi networks and choose the one that says something like: Huawei-08A3. You will need the wifi password / key so open up your mobile wifi device again. The wifi key is printed on the back of your battery. Enter that and you should be good. (The whole admin thing it mentions in the Quick Start doesnt work.) Your phone should now be connected to the device. You should now see the device in the app on your phone. If you click tools in the app you will see SMS this is where messages to that SIM number will show up. If, like me, you register and buy credit or a plan online, the telecom will send your confirmation code here. You may need it to confirm your account. And if you need to use a French phone number during your trip for any reason, you can receive messages here to the local number that came with your SIM card. Otherwise, as long as you have “Wi-Fi” voice calls enabled on your phone, you should be able to make & receive calls on your US phone number and not have roaming charges. In fact, keep your phone on airplane mode to make sure. Hope that helps someone!

The unit is small & light however the battery doesn’t last more than 3 hours of combined standby and working.

After about a month of using this product the battery will die even when you have it plugged in to charge, not worth the money

not what I thought it was. Returning tomorrow.

ME LLEGÓ EL ARTICULO Y TUVE QUE PAGAR 25 EUROS DE ADUANAS PARA RECIBIRLO , CUANDO LO ABRÍ NO TENIA CONEXION PARA LA ANTENA Y TUVE QUE DEVOLVERLO A ESTADOS UNIDOS Y PAGAR YO MISMO LOS PORTES... NO LO RECOMIENDO PARA NADA. MUY INSATISFECHO

Past the deadline to return. And was not able to use it during my trip to multiple different countries. Complex logging in process on the website that makes it impossible to get this to work. Do not waste your money on this

Not worth ten cents...I sent it back the next day. Will only work on 3G and one bar of signal. I think dial up is better than this thing...

Unit will not recognize T-mobile SIM card. So, Huawei APP was useless as well. Wasted my time trying all different ways to configure it. Watched several different YouTube videos, nothing worked. T-mobile will not give you Mobile Hotspot SIM for free to try, you will need to purchase their WiFi Mobile Hotspot plan. Your phone SIM card will not work, you will need specially configured WiFi Mobile Hotspot SIM.

I had to return it. It didnt hold a charge. Very disappointing.
