How to unlock the Huawei E1550 3G Modem

August 9, 2010 Neil

Read this guide and find out how to unlock a Huawei 3G Modem. Detailed step-by-step guide.

Huawei 3G modems are shipped out by providers are usually lock. Read on and find out how to easily unlock your Huawei 3G Modem.

Most 3G modems available are locked to a single network to avoid the use of SIMs from competitors with similar or better service. As all product of technology, there are ways to unlock these modems.

The following step-by-step procedure on how to unlock your Huawei E1550 3G modem. The same work may work with other models but I can’t guarantee the result will be the same.

What you need?

Calculating the Unlocker Code

All Huawei 3G modems come with an IMEI Number (International Mobile Equipment Identifier). The IMEI will be used to calculate for the unlock code using the Huawei Modem Unlock Code Generator.

You can also go to this website to generate the unlock code.

1. Determine the IMEI Number of your E1550 3G Modem by removing the micro-SIM. It will be labeled as “IMEI”.

2. Open the Huawei Unlock Code Generator.

3. Enter the IMEI Number in the field provided and click the “Calculate” button. Take note of the “Unlocker Code.”

Now that we have the unlock code, we’re going to write it in the 3G modem to open it. Remove the micro-SIM card and connect the 3G modem to the computer.

1. Open the Huawei Modem Code Writer.

2. The Code Writer will automatically detect the modem. Make sure that your modem is selected under “Comport Setup.”

3. Press the “Unlock Modem” button. A pop window will appear asking you to enter the code.

4. Enter the code on the field provided and click “OK”.

Now you have an unlock Huawei E1550 Modem. Be wary of unlocking the modem as you may encounter errors beyond repair.


1. I’ve recently found out that there are Huawei 3G Modems with Customized Firmware. Modems with this firmware cannot be unlocked. You need to flash/update the firmware first before performing this unlocking procedure.

If you are getting the “ERROR” message, it’s probable that you have a customized firmware loaded in your unit.

How to check?

Go to Download the software and install it.  Plug the modem, open the DC-Unlocker and click the “Magnifying Glass” icon.  The progr am will detect your modem and provide the info.

Look for “SIM Lock Status”.  If it has a customized firmware, you will get this:

SIM Lock status : Locked (customized firmware)

      Similar story. I am a 45 year old male – 6’1″ and 200 lbs. I’ve kept a running log for years and have always noted a substantial loss of endurance and slowing of times in the weeks after blood donation. My typical recovery to pre-donation performance is about 4 weeks (not that I am into performane – 8-9 minute miles / 20 miles per week). Never have I been able to validate others issues with this until now, so I am thankful for this forum. I will continue to donate, but truly feel the Red Cross is negligent in not warning potential donors of this in the pre-read literature.

      My Info is my only Facebook application that is set up to be translated and its only set to allow Spanish. Facebook has the translation features built in. I can activate another language if you are interested in translating it.For my other Facebook applications, such as My Greetings and My Status, I haven’t had any requests for translation or anyone offering to translate. It is a fair amount of work to make the application translation-ready, so I haven’t bothered until there was demand.

      Designing a blog is totally beyond me! I don’t know how to get the sidebars to line up right, or make buttons appear on not just the main page but every page. I think I could figure out what to blog about and PR and all that, it’s the mechanics that baffle me. I could use some help!! I think MetropolitanMama is the blog-BOMB and I know I could learn a lot from her ebook.


      Thank you for sharing excellent informations. Your web-site is very cool. I’m impressed by the details that you have on this site. It reveals how nicely you understand this subject. Bookmarked this website page, will come back for more articles. You, my friend, ROCK! I found just the information I already searched everywhere and simply couldn’t come across. What a great site.

      Website looks amazing Will. I love the layout and colour scheme!The site seems easy to navigate and as simple as possible which is the key, busy sites lose peoples interest fast, even if they are aesthetically appealing, so you have done a great job paring it down. As for the logo in the top left, I think it was a good choice, this is a common feature of major websites for use as the “home” button. Great work man!

      In attesa di quella di Beau, esprimo la mia opinione sul quesito, cruciale, posto da roberto vallefuoco. Per prendere voti il Pd, a partire dalle c.d. “primarie” continua ad affidarsi a chi ha gestito il potere: ca&apistonebamp;seguaci (di tutte le componenti), mentre una Paola De Vivo, capolista, non viene eletta. Idem la Capacchione, in precedenza. Così non si va da nessuna parte.E’ solo un esempio, e ribadisco che la suddetta strategia viene, purtroppo, adottata da tutti i partiti del centro-sinistra.
