Technical Specifications


The ZTE MF823 from Chinese telecommunications equipment vendor ZTE, replaces the current model MF821D from O2. All thing should be mentioned that ZTE MF823 is not the best USB stick when the ZTE MF825 is also in its product range. It supports LTE category 3 (max. 100 Mbit) and therefore with all networks from O2. In any case, the mobile service provider can offer data connections on the basis of category 4, which allows data rates up to 150 Mbps. It supports the LTE frequencies at 800, 900, 1800 and 2600 MHz – for operation in European countries. Likewise, the MF823 could also support DC-HSPA+ (to 42.2 Mbps), UMTS and GSM networks.



Unlike the Speed Stick 4 by Telekom, the stick fortunately has two connectors for an external antenna – optional to improve reception. Like almost all other models, user can insert a MicroSD memory card of up to 32GB of storage space for data of all kinds.



Users do not have to install an extra software for the MF823, which would be auto connect to network. It is controlled conveniently from the browser via the web interface. It is enough to enter the following IP in the browser: The interface shows all important data at a glance. And you can see, how much volume you have already used in the current billing month. The stick is also compatible with the IPv6 protocol. According to the manufacturer ZTE, the MF823 uses about 1/4 less power than even the previous generations. It’s special for operation on a laptop or tablet. We are also pleased that quite modest dimensions of the model. At just 13 mm in height and 26 grams, it is one of the shallower representatives of its kind. It is alleged that the world’s smallest LTE data modem. Important to mention would be that there is no SIM lock, so the drive can be used with Contract card of other network operators.


The ZTE MF823 for O2 can provider users at an acceptable price for mobile Internet. With slim size and decent network support, it could be good partner for laptop. It’s available on www.4gltemall.com . But if you want to find better models, the Speed Stick III or the Huawei E3276, may be good options, but they are also more expensive.



Huawei E5220 HSPA+ WLAN Router Test

Huawei E5220 Mobile Wi-Fi hotspot is a small mobile pocket router that can forward the UMTS internet connection via WiFi for up to 10 devices simultaneously. In comparison with other portable Wi-Fi hotspots, we will soon find out that the Huawei E5220 without contract belongs to the best devices of its kind. With the low weight of only 66 grams and dimensions of 90 mm x 56 mm x 14.4 mm, Huawei E5220 is a unique mobile hotspot. And the price of Huawei E5220 is good, so how does the price affect the performance? Let’s have a look at the result of HUAWEI E5220 test.


HSPA+ up to 21.6 Mbit/s


Following the Huawei E5 series, Huawei E5220 also works both in GSM network and the UMTS network, LTE is not supported. In the UMTS network, the download speed of up to 21.6 Mbit/s via HSPA+ is available, of course, it depends on the configuration and utilization of the network. In the test, we use the HUAWEI E5220 under the Vodafone network, a maximum speed of 14 Mbit/s downstream and 3.3 Mbit/s upstream; while with the network of Deutsche Telekom, the speeds 4.2 Mbit/s for downstream and 4.1 Mbit/s for Upstream were possible. The ping times were at 35 – 80 milliseconds over UMTS, depending on network and usage. The usable frequency bands are the 900 and 2100 megahertz with UMTS/HSPA+, and 850/900/1800/1900 MHz for GSM/EDGE.


  Four status LEDs on the front panel next to the Power button indicate the current operating status. Further information can be obtained only through the web UI of Huawei E5220, more on that. The connection to the computer via Wi-Fi in the 2.4 GHz band, up to 72 MBit/s is supported (Wi-Fi 802.11 b/g/n). Even if you are not too far from the router, the full 72 Mbit/s WLAN connection speed can’t come true at the terminal.  

Only 3 hours battery life


The size of HUAWEI E5220 is very slim and in pocket size. The battery of Huawei E5220 removable and the capacity is only 1150 mAh, so in the test, the working time only lasts just under 3 hours at use in the train and at stationary use. On the other hand , the expensive 4G Mobile devices like the Huawei E5776  offer up to 10 hours. Positive note, the battery is easily replaceable and can therefore be replaced with a defect without effort.

The operation of the Huawei E5220 hotspots is normally done via a web interface in the browser. There, next to the SIM pin, for example, network technology (automatic, 2G only, 3G only) or the provider could be selected. Information is also available about data volume and the online time. For smartphones and tablets with the Android operating system or iOS, an app is also available, which also presents the most common settings and information.

Conclusion: simple mobile WiFi hotspot


After the test, one thing is certain: Those who seeks extras like an external antenna port or a slot for memory cards, the Huawei E5220 is definitely wrong model because E5220 has not the external antenna connector and the SD card slot. But for those who want to surf high speed on UMTS, not LTE, Huawei E5220 is definitely worth a look: price, size and weight are unbeaten so far, as well as our Pocket WiFi column shows.  


Here now, Huawei E5220 is already branded for the operator Vodafone, the model number is Vodafone R206. If you want the branded E5220, Vodafone R206 is a good option for you.

HUAWEI E5332 E5332s-2 3G Mobile WiFi Hotspot Review

As the sister model of HUAWEI E5331 Mobile WiFi, Huawei E5332 may not as popular as Huawei E5331, in our opinion, Huawei E5332 may be better than E5331. Today, let have a look at this new 3G pocket WiFi.  

  When we first get the package box of Huawei E5332, we feel it weights more than E5331. And the box is bigger than the latter. We are thinking what’s in the box and cause the weight difference. In our memory, in the box of Huawei E5331, there is only E5331 device, one short USB cable and a battery. When we open the box of Huawei E5332, we could see the E5332 device is in a small plastic protective bag.  


Removing the paper plat, the packaged contents are listed at the bottom of the box: on black power adapter, user manual guide, safety information paper, one battery and one short USB cable. The power adapter should be the key which cause the weight difference. Actually, the weight is not that important, the users concern more about the application and convenience brought from Huawei E5332.


Huawei E5332 Mobile WiFi is also in pocket size like E5331, but it’s thicker than E5331 at the body side. Huawei E5332 should use the same module as Huawei E5756 mobile WiFi, we suppose.  

Following the simple design of Huawei E5331, the Huawei E5332 also has one button for operation, mainly for power on and off. Beside the power button, there is a LED indicator where we can see the Huawei logo, signal strength and connection status, message information and remaining battery.


The USB interface is at the body side, close to the USB interface, it’s an external antenna connector. The connector is covered by a protective cap.

And we open the back cover; we can the SIM card slot, model stick. The stick information on the image below:


But there is no Micro SD memory card slot in Huawei E5332. We found there is a reset button at the inner side of the body. It’s to set the device to factory default.


After the SIM card plug into the slot, put the battery in the body. Then power on the Huawei E5332, the LED indicator will shine to indicate the connection status. On the inner part of back cover, there is the SSID and WiFi password information.


After your WiFi device gets connected with Huawei E5332, then you can surf Internet and don’t meet any settings. HUAWEI E5332 Mobile WiFi is a good pocket WiFi for surfing.  

How to Setup HUAWEI E5332/E5332s-2 3G Mobile WiFi?

Usually, the HUAWEI E5332 Mobile WiFi, also named HUAWEI E5332s-2, don’t need any setup and it would automatically connect to the network, the devices connected to this mobile WiFi and then surf freely.

However, sometimes, the HUAWEI E5332 mobile WiFi may can’t read the SIM card and it would not auto connect the network. So user need to setup and configure the HUAWEI E5332 manually. Below are the steps to guide the setup:

1. Plug the SIM card to device HUAWEI E5332

2. Power on HUAWEI E5332

3. Connect the WiFi device to HUAWEI E5332(the SSID and WiFi key are on the back cover inner part)

4. Land the web management page:

5. Log in by user name: admin, password: admin

6. After log in, under the column “Settings”, click “Quick setup”

7. Set up a name, the name could be any name per the preference and enter in the APN of the SIM card provider

8. Then click to next step, configure dial-up settings

9. Then next to configure WLAN Settings: SSID

10. Then next to configure WLAN WiFi Key, encryption code

11. The next to configuration Summary, confirm and click “Finish”.

12. After few seconds, HUAWEI E5332 could get connected with the network. And terminal could surf under this support.  

This is the easy setup and configuration of HUAWEI E5332 Mobile WiFi. Hope this will help most of the users who are in trouble. These steps are also applicable for HUAWEI E5331 Mobile WiFi.

But before this setup, user must confirm that the SIM card operator could provide the 3G UMTS bands at 900/2100 MHz, which means if there SIM card is running on the band 850/1900 MHz, it’s incompatible with the device. Or it can only work on 2G network.  

Two Recommended HUAWEI Mobile Power Bank

Most of people know that HUAWEI is a professional wireless gadgets supplier, but few people know that HUAWEI also produce mobile power bank. You may be curious that what power bank that HUAWEI could supply. Of course, as the world’s top telecom equipments supplier, HUAWEI would not supply the common kinds of colorful power bank in the market.  

Considering the great volume of gadgets that are already at the users’ hands, HUAWEI wants to find a resolution for its mobile terminals about continuous power supply. So it’s necessary to recommend HUAWEI new power bank so that users could get better experience and keep surfing without any interruption.

  HUAWEI Charger Partner — 5200mAh Mobile Power Bank (CEB-Li01-5200 mAh)  

As we know, HUAWEI only released this charger partner at the battery capacity of 5200 mAh. It should be based on the consideration that the usual HUAWEI mobile Smartphone and mobile WiFi incorporates the battery around 2500mAh, so it’s better for a power bank to give one device twice support after one time power charge. With this capacity, the cost of battery is acceptable and easy to take for users.


This power bank could use as flashlight. With only 200g weight, it’s easy to take in hand or pocket. With a mini USB connector, it could support two devices to charge power simultaneously. And the USB could use for most of the mobile Android phones, tablets and mobile WiFi hotspots.  

Somebody may ask, here now I don’t have a mobile WiFi, but I do need a mobile WiFi and power bank 2 in 1, is there a device have this function? The answer is yes. HUAWEI had focused on the demand from customers, so they released a new mobile WiFi and power bank 2 in 1 gadgets, the model number is HUAWEI E5756:  

HUAWEI E5756 Mobile WiFi and Power Bank 2 in 1  

HUAWEI E5756 has the basic function as a HSPA+ mobile pocket WiFi to support up to 5 users to share the wireless network. The peak download speed could reach 42Mbps and this is the fastest 3G download speed that a mobile gadget could reach. Then the extra function as a mobile power bank, HUAWEI E5756s-2 could not only give Android phones, tablets and other mobile terminals power supply, it could also extend itself usage time.


Based on HUAWEI quality and HUAWEI brand, the two batteries are very popular and reliable, so if you want to buy a qualified battery charger partner or mobile power, you could take the two batteries into consideration.

Huawei E5331 Mobile WiFi Hotspot Test Report

Mobile hotspots are now very popular and we have a favorable time and new model for a test: the Huawei E5331 Mobile WiFi. The small wireless router comes in a compact package, in addition to the device itself, there is only the powerful 1500mAh battery and a small USB cable included for charging. An AC adapter for charging directly at the outlet does not packed in the box.

After unpacking, if you have only the SIM card (Normal standard size) and insert the battery, then you can turn on the Huawei E5331. The HUAWEI E5331s-2 has a LED display screen, after a few seconds to light up a few status LEDs on the front, HUAWEI E5331 will start working. At far left is a reception display, next to the light for the wireless network and an indication of the battery charge. On the far right there is a message icon that indicates new SMS.


After the first start you have to connect via Wi-Fi with the Huawei E5331, by the way, more than 8 devices can be connected via Wi-Fi. The password for the wireless network is located under the battery in the device, you should write down the code before E5331 begins operation. After a short search network, the modem automatically selects in the mobile network – certain settings such as the APN to be incurred only in exceptional cases, in most cases, no configuration is required by the user.


The reception in the UMTS and GSM operation is pretty good, and definitely better than many cell phones. In the UMTS network, HSPA + data rates of up to 21.6 Mbit/s are possible, and I was able to reach a maximum of 17 MBit/s downstream and 4 Mbit/s upload in the telecom network, so what are already quite good values! Upon request, the Huawei E5331 menu also allows to “3G only” switch, so that even if the signal is weak is always the UMTS network is selected and not a throwback to the slow EDGE / GPRS.


The battery life is about 5 hours of continuous use, requiring the E5331 for about 2 hours at the outlet (or on the computer, if you have a USB charger). All in all, the Huawei E5331 Mobile MiFi router makes a very good impression and for the price of around 99 US dollar without contract and SIM definitely unlocked.
