Unlocking a 3 USB Modem (Huawei E220)

I purchased two Pay As You Go 3 USB Modems a few months ago from Sainsbury’s reduced from £49.99 to £12! I thought they would come in handy if I needed to go mobile with my notebook. My Orange High-speed circuit-switched data (HSCSD) data card is a little slow these days. I can surf the internet with a speed of 14.4kbit/s or if I use two time slots (bonded) can achieve a blistering speed of 28.8kbit/s, this is over the GSM network.

The 3 (http//www.three.co.uk) USB Modem is manufactured by Huawei. The model number I’ve purchased is the Huawei E220 HSDPA USB Modem. This model is often called the ‘pebble’, because it resembles a pebble, and is a small ‘dongle’ type device which connects to your computer using a USB cable.  Some folk may be put off by this model in favour of the newer “chewing-gum type sticks” modems available.

The issue I have is that 3’s Pay As You Go data tariff involves “topping up” with £10, but this does not roll over to the next month, if a portion remains unused, you need to top-up again. For £10 you are given a data allowance of 1GB. I don’t find this suitable for my use, I’m only going to use this device . occasionally. A much better tariff for me is the ASDA Mobile Pay As You Go Tariff, Calls – 8p per minute, Texts – 4p per text, Data – 20p per 1MB. ASDA mobile phone tariffs are a steal. But unfortunately, you cannot just use an ASDA SIM Card in a mobile phone which is locked to the other vendors network! I tried the ASDA SIM Card in the 3 USB Modem, and although it recognises the PIN number, it states “invalid SIM”. This is because the 3 USB Modem is SIM Locked to the 3 Network.

Luckily there are software programs that can over-ride this lock. I’ve used the following procedure to over-ride the lock in a 3 USB Modem (Huawei E220) and replace the 3 SIM Card with an ASDA SIM Card. Your mileage may vary, and I will not be held responsible if this procedure fails, and turns your 3 USB Modem into a brick (breaks it!).

  1. Remove SIM Card from USB Modem.
  2. Connect USB Modem to computer.
  3. Download DC-Unlocker Client v1.00.0267 from authors-site or here.
  4. Install the above software on your computer where you have installed the 3 USB Modem.
  5. Start the DC-Unlocker Client on your computer.
  6. Click Buy Credits. You’ll need to register with the DC-Unlocker website, and purchase 15 credits. (15 Euros) to unlock the E220.
  7. Input your username and password into the DC-Unlocker Client, it should verify your details and confirm your credits.
  8. Do not change any other settings. Make sure select manufacturers – Huawei datacards is selected, and select model is set to automatic.
  9. Click the Magnifying glass.
  10. With no SIM card installed the following will appear

  1. The USB Modem is unlocked.
  2. Exit DC-Unlocker.
  3. Remove USB modem from computer.
  4. DC-Unlocker client works for me with the above firmware.
  5. If you re-insert your 3 SIM Card and connect to computer, the 3 software should still function.
  6. To use another SIM to connect to internet requires the Uninstallation of the 3 software and the installation of generic Mobile Partner Software from here.
  7. Install the Mobile Partner Software from above.
  8. After installation, and only after a successful installation connect the USB Modem.
  9. Plug ‘N’ Pray should install new drivers for the USB Modem.
  10. Start Mobile Partner and create a new Profile for ASDA, ASDA uses the Vodafone network, but doesn’t use the Vodafone APN!
  11. Open Mobile Partner application, choose Tools – Options – Profile Management – Click New
  12. Create a new profile. e.g. ASDA or Vodafone
  13. Select APN – Static – APN name is asdamobiles.co.uk
  14. Authentication – Access number – *99#
  15. username and password – web/web.
  16. You could create a Three Profile, details are APN – APN
    3internet. Username and password – leave blank. 
  17. Hopefully you be able to click connect and use the Internet via ASDA mobile network.
  18. I think the generic version of Mobile Partner is a much better application than the “noddy” 3 USB Modem application.
  19. The above procedure may work with different providers.
