As you might have realised, the E303 modems are the latest kind of modems in vogue now and unlocking these modems are quite demanding unlike glo E173 modems and other earlier versions but on this post, i will be showing you exclusively on how to unlock the new glo bolt modems and MTN Huawei E303 modem.
First and foremost, I’d like to apologize to my readers for not posting this tutorial on time and I’d hope you forgive me for this.
To my speculation, i think most Nigerian network providers have resorted to using these new model of modem basically due to the fact that other versions of modems can be easily unlocked thus giving room for other network sims to be used on same modems but they is always a solution.
Unlocking GLO BOLT / MTN Huawei E303 Modems
First, you will be needing a software called DC-Unlocker, its same as the one i posted on the tutorial relating to unlocking glo netpro modem but that software called be used in unlocking this sort of modem. I’d recommend you download the latest version of this software which is version dc-unlocker_client-1.00.0975 from dc-unlocker website here.
You also need a working dc-unlocker username and password, this is required for authentication when unlocking the modem using the dc software.
You also need to have dc-unlocker credits loaded on your account username and password, depending on your modem but I’d recommend getting like 6 credits and 1 credit costs 1 euro. You can purchase credits via www.dc-unlocker.com/buy using paypal funds.
You will be needing an active internet connection on your computer, this is to enable your dc-unlocker software connect to the internet in other to verify and successfully unlock your USB modem.
Have you got all that in place? Next…
Connect your Glo Bolt or MTN Huawei E303 USB Modem to your PC with an unsupported sim card via a USB Port and when it prompts you to insert your unlock code, simply close the modem interface window and launch your downloaded DC-Unlocker Software.
Use the DC-Unlocker Software as i have formally illustrated on this post to detect your E303 modem. After successful detection, click on Server and input your already credited username and password.
Head back to the Unlocking option and click on Do Job, the software will connect online and after successful verification of your username and password, your huawei modem will be unlocked and you should get a successful notification.
Close DC-Unlocker, remove and re-insert your GLO or MTN E303 Huawei Modem using an unsupported device and you shouldn’t get an error again because you are good to using your modem with other network sims.
This tips should work in unlocking both E303 Huawei and ZTE modems, for more questions or comments, please use the comment box.

How do I get a username and password for d DC unlocker software?
You will be provided with a password to your username upon buying a credit from them.

sir ,the way you explained how to unlock the glo bolt e303 can’t work.because that was the old method of unlocking e173.the old one will request for unlock code the moment you insert another network into it.BUT THE NEW ONE WILL NOT REQUEST FOR CODE RATHER IT BE ANOTHER MESSAGE IT WILL DISPLAY.

Dc unlocker does not support the glo e303 modem yet.It is only good for e173u-2 airtel and e303 mtn and a host of others modems(zte)
Basolan, it works with glo bolt modem bro. the modem is also e303 just as mtn new fastlink so it should work.
I have actually tried it.I bought ten credits and performed the operation.The software says it was a success and 4 credits was taken.I reran the software to check the modem status and realized it is still locked.I got in touch with dc unlocker`s support and they confirmed the glo e303 is not yet supported because of a customised firmware.My 4credits was returned.I am talking from experience.
