I will first have to apologize for the delay of this article. The truth is tat i was preoccupied with how exactly to write it, i mean what to including and what to omit. Now i have resolved to simply write about various buying guides on a usb dongle as well as hints on how to unlock (a 3g / 4g modem that can be unlocked) a usb internet modem.


usb internet_dongles



A 3G modem is a device that allows a computer to connect to the Internet via a high-speed mobile broadband connection. This means that the Internet signal is broadcast over the airwaves rather than sent and received through a cable or telephone line. The technology is largely the same that is used for delivering Internet content to modern cellphones. I am personally using a zte mf667 modem and it is not compatible with my azsky g6, strong 4922a and qsat q11g. The only way i have been able to use my modem with my decoder is through my numerous 3g routers. Modems are cheaper than 3g routers / mobile broadband, however if you are new, i will advice you to buy a mobile broadband router and plunge into a world of more possibilities instead of going through the inconveniences of selecting a 3g modem for your decoder. A very good mobile broadband router can be found here


The simply truth is that, you can buy just any internet modem if your sole aim is to use it with your computer. You can buy a universal modem, a wcdma modem(e.g multilinks, swift 4g, e.c), you cn buy a branded, or a modem that is locked to a particular network service provide… e.g mtn nigeria fastlink, glo bolt, etisalat datacards e.t.c. All you should put in mind if you want to buy a modem for your computer only is ; 1. Durability and 2. Flexibility (I mean can it be unlocked) If you need a durable modem, huawei has an edge here but new versions of huawei are very difficult to unlock in fact only mtn huawei can be easily unlocked through a paid software known as dc-unlocker. So if you can find a powerful universal modem, you may give it a shot.


This is a very tricky question to answer, However i will try and leave no stone unturned in addressing this issue and i will love your sincere contributions on the list of modems tested to be working perfectly with a decoder.

  • The Ultimate guide when buying the dongle is for you ti inform the seller before hand that, if it doesn’t work for your decoder, you will return it and collect your money. The reason being that, everyday new 3g modems come out and it becomes more difficult to get the one that works with your decoder. This is not an easy move though.
  • Huawei modems are generally compatible with all decoders that supports a 3g modem. For example, strong, and azsky g6 only support any huawei 3g modem. while qsat decoder supports zte mf190 and all huawei 3g modems.
  • A universal 3g / 4g modem has 95% probability of not working with your decoder so if you have it in mind to use your modem directly with a decoder, avoid a universal modem as much as you can.
  • Any huawei 3g modem from any internet service provider will work perfectly with any decoder that supports a 3g modem(Note: we have both 2g modems and 3g modems, a decoder supprts both but you wont be able to use your huawei modem to connect your decoder to the internet. Examples of huawei 2g modems are e621, and zte mf110. Please don’t use a 2g modem on a decoder that supports 3g modems
  • My in exhaustive list of usb data cards / dongles that have been tested to be working with all kinds of decoders are ZTE MF190{Works with qsat), Huawei E173, e303, e355.. and newer works with qsat and other decoders that supports 3g modems either through software upgrade or out of the box.
  • 3g / 4g modems tested not to be working with qsat and other decoders are:  newer versions of swift 4g modem, zte mf673, mf667 and newer, most universal modems, any 2g modem.
  • You should also know that some 3g models seems to share same model number, but they are not the same. Airtel huawei e173u-1 modem is different from Airtel huawei e173 modem. They will both work with any decoder, but Airtel huawei e173u-1 cannot be unlocked why you can easily unlock airtel huawei e173. Their is advance customization of e173u-1 while we only have simple customization of huawei e173. So beware. same goes for zte.
  • The only network provider that offers modems that can easily be unlocked either through paid means or with a free software is MTN Nigeria. Etisalat, airtel and glo modems are almost impossible to unlock. What this means is that once you buy them, you will be restricted to using only their sim cards for a very longtime to come
  • A modem that cannot be unlock today, can be unlocked tomorrow but up till now, airtel huawei e173u-1 cannot be unlocked. There is a paid software software that can easily unlock any router or modem that supports unlocking. Please check the site out here and make sure you check the model of your device properly
  • To actually get your compatible usb modem to work with your decoder, you need to follow my guide here
  • List of current iks / FTA decoders that supports a 3g modem either by software upgrade or directly are: zorrobox z3, qsat, speed hd s1, azsky g6, strong decoders 4920, 4922,4922a, tlink 600hd and a host of others
  • Older usb huawei modems can be unlock with a free software named Universal mastercode generator I will drop a link on it later.. It unlock huawei modems produced ealier than e173u-1.. that is it can ulock huawei e173 and older. In fact someone can help you unlock older huawei modem without seeing your modem what he needs is your modem imei number.
  • All zte modems can only be unlocked through hardware unlocking. In other words, you must connect the zte modem to your computer before using the paid tool to unlock it
  • Am yet to see any mtn zte modem that cannot be unlocked. Etisalt mf 190 modem, airtel mf 190 and glo mf190 can also be unlocked using dc-unlocker. mtn mf667, can be unlocked as well. My problem with zte modems is that it is difficult to find a zte modem that can work with decoders.
  • It is also possible to get a universal modem that will work with a decoder. Am yet to come across any.



I will say that this is a continuous process, the most perf=worful tool that can unlock any modem or router that is unlock able still remains dc-unlocker. Another interesting about dc-unlocker is that, with the release of newer versions, more devices are supported. However, dc-unlocker is a paid software.

All the screenshots I shall be using here, is courtesy of http://geek.ng.


When  say older huawei modems, i mean modems such as e173 and older. This also works for Nokia, LG and some other products apart from Huawei USB modems.

    Qsat have many server but not one channel to a server
    A set of channel use one server let’s say 5 channel to a server
    Remember when qsat 23g came out it was announce as the most stable iks decoder better that qsat 11,15,13

  52. kaba edward says:

    balinjar thank u for de info at least u have sooth my heart but may i know ur source of dis infor.thanks

  53. Oga lemmy, i want to purchase a cccam account and i have contacted you on two occasion without you responding.
    Please check and respond to msg.

  54. hi lemmy
    d**v scanning process in now 22 not 26 again, pls whats d meaning, pls break it down.
    Tnx broda

  55. The
    question is, is qsat prepared to quit
    from business? i don’t think so
    looking at the huge profit they have
    made so far. No business minded
    person will ever quit a business he
    so much profit from. Qsat present
    predicament is as a result of past
    and current d*stv upgrade. Qsat
    sever is no more the way it was
    when it was newly released and the
    entire qsat team of engineers are
    currently on a serious sever update
    to be able to bring back service. This
    exercise will take some time to finish
    because programming is not an easy
    thing to do. Let me give you a gist of
    how it is done. Every single channel
    has one sever controlling it but is
    been decrypt with about ten
    different codes. All ten codes has to
    match with original d*stv decryption
    code if not that particular channel
    will not be stable and that is why,
    some channels freezes more than
    others. Also the more code available
    determines the sever to be created.
    And number of severs created
    determines the number of channels
    broadcasted. Some codes are
    stronger than others and that makes
    a particular channel more reliable
    than others. For now, all codes are
    not complete for programming and
    it is the reason for the delay but all
    effort are in place to put things
    together and very soon, qsat will be
    back to full glory.

  56. @Lemmy and Shamsu. I hv d same modem airtel E173U-2 and paid Dc-locker but it didn’t unlock.

    THE END ? Is it the end of qatsat? or the end is near.It seems to be obvious dat a couple of housemates have their qsat running on tv1.The discussions in de house is gradually waving towards tv1.Is now de matter of who can chase after starting from avater 2,liberty,azsky,A+.Though tv1 is not a decoder or a dongle its cost seems to be more dan a dongle.The option for now is tv1 but de question is how frequent will de goal post be shifted.It looks as if de engineers of these products know what do but do dat at a strategic time dat inure to their benefit.WE WISH FOR WAR NOW WE HAVE IT.We want DSTV to watch de consequences are with us.AMEN.

The process didn’t resolve the view, but I had a 3G modem (Veedaa by name) its never worked on my G6. After a factory reset in a bid to make the Cccam work, I decided to just try the modem, and just discovered its working. Would u know how this happened?
