Unlocking BSNL EVDO AC8700 usb modem

 

I have been using BSNL EVDO since a year. Many people have asked me on how to use BSNL EVDO data card (AC8700) with other CDMA operators.

The below content applies to BSNL EVDO data card model AC8700 manufactured by ZTE only. I have tried to put details, still may have missed as I am in a hurry to leave for somewhere.

First of all almost all BSNL EVDO data cards are unlocked. However you may face an issue of not detecting the T-SIM card.

To solve this:

Time Needed: 10 minutes max.

1. Download the DFS software from http://www.cdmatool.com/Download.aspx or http://www.mediafire.com/?fhh4n5gsrf6alnf (Its free)

If you need the latest BSNL ZTE AC8700 EVDO software download it from http://www.mediafire.com/?r526z47x4cab0t1

2. Install the software, its basic install. Do not start the software now. If the software is on you can close it.

3. Connect your BSNL EVDO modem AC8700 and start the DFS software now.

 

DFS_Main_Screen_sushantgarg.com

 

4. Click on ‘Ports’ on top left.

DFS_Port_Screen_sushantgarg.com

Look for ‘ZTE Service Port FFFE (Com??)’. Double click on it.

 

DFS_Port_Screen-2_sushantgarg.com

Your modem should be listed as in above image. If not try double click again on the ‘ZTE Service Port FFFE (Com??)’.

 

Close the ports screen and get back to main screen. It should be like in the image below:

DFS_Main_Screen_active_connection_sushantgarg.com

5. Check the second line on top left. The Icon before the Port name on top left is green or not and the ‘ZTE Service Port FFFE’ should be listed.

Important: Don’t change anything else than what is mentioned here.

The SPC box by default has ‘000000’. If not put ‘000000’ in it. And then click on SPC button.

DFS_SPC unlocked_sushantgarg.com

You will see ‘DEVICE Unlocked’ in the bottom screen.

DFS_SPC unlock_failed_sushantgarg.com

In case it shows ‘BAD SPC VALUE  UNLOCK FAILED’. Double check that SPC is ‘000000’ i.e 6 zeroes. Still its shows error means SPC is different and needs to be hacked. Which is easy and I will write about it later. My guess is you wont stuck here.

 

6. Now go to ‘Programming Tab’. by default it shows the “General sub tab’

DFS_Programing_Screen_general_tabsushantgarg.com

In the Config Box on right side click Read. It should display current settings in the respective boxes.

In the ‘Ruim Config’ box select ‘Ruim Pref’ and click on write.

By selecting Ruim Pref, now when you insert a T-SIM in the modem, it will start using the SIM and once you remove it, it starts using the inbuilt settings of your home operator. Here BSNL.

7. Click Reset on the right top side on software. Close the software.

8. Test it and let me know if this worked for you. Do ask if you face any problem.

 

Have a nice day.

  1. Thank you so much for posting step by step instruction. I will check this out on my 2 years old bsnl ac8700 that i am not using at the moment. Hope i will be able to use it on my macbook on international tour. Highly appreciate your efforts!

    1. The data card may not work in some countries, depends on the country, operator you will be using. It is designed to work on on CDMA 800mhz. Check this page to know the frequency of the mobile operator.

  2. I did follow the steps and have unlocked the ZTE AC8700 device. Since, this device is based on CDMA tech, What should I do next?

    1. Hi, you can use t-sim (cdma sim) of any other operator in India. Use it for accessing Internet, making calls, sending sms.

      Delete
    2. As suggested, should I load the cdma sim, when the device is still connected to the software. When should i use the "reset" button i.e., after loading my sim or before loading it.

      Also, is this a permanent unlocking? As stated by you, if I remove the sim, the device gets back to the original state i.e., bnsl. Should I unlock, incase I remove my sim by mistake......... Hope these questions do not bother you much

  3. Hi,
    Once you have completed the above steps. You don't need to open the DFS software again. You just have to use the ZTE software that came with the device.
    The above solution is permanent.

    Always insert the sim card after removing the device from computer. The reset is basically removing the device from computer and attaching it again.

    Here's how the data card works after unlocking:
    Lets say you insert a sim card of TATA INDICOM into the device. Then tata will be active. You can use services of tata like call, sms, internet thru ZTE software.
    When you remove the sim card, the default network i.e BSNL should be active again.

    Don't hesitate to ask, if you face any problem.

  4. Thanks Sushant for your immediate reply. I will try Reliance CDMA sim today and will catch you up later

  5. Dear sushant,

    Well. I tried the reliance CDMA sim and I am able to acess internet. Now i realized that I have to use the connection as a mobile phone (internet connection via a mobile number) and not as a dedicated device for accessing internet. Is there any option for using it as a dedicated device since the other idea seems to be bit costly ( connection speed is also 1x). I feel that the speed of accessing internet via BSNL was pretty faster. Is there a possiblity of getting a BSNL R-UIM card and and enjoying the 2g or 3g speed or will it be 1x as that of reliance or tata or......etc.

    1. Hi, I haven't tested EVDO service of Tata & Reliance. Just the 1x one which is definitely quite slow. In my city BSNL does not provide RUIM sim card.

      Delete
    2. Dear Sushant,

      I tried with BSNL EVDO enabled RUIM prepaid card and the device works fine. It has the 1x speed and wherever EVDO signals are good, I expect a higher speed. The postpaid connection from BSNL can be converted to prepaid by purchasing a prepaid R-UIM card (after unlocking the device AC8700).By converting it a BSNL prepaid connection, the device
      can be used solely for accessing internet.

      Thanks a lot for the tutorials.

      Delete
    3. Hi,
      It's good to know that postpaid can be converted into prepaid. In my city they aren't selling any prepaid plans.

      If I understand correctly you are able to connect in EVDO mode but getting low speeds. This certainly is BSNL's problem.

      Delete
  6. Thanks for the tutorial. I have one question, can we use the same operator (in this case, BSNL) prepaid CDMA sim and it would work? I unlocked my ZTE modem provided by BSNL on postpaid plan and would like to subscribe for the prepaid sim. Will it work or it needs to be different operator sim only after unlock?

    ReplyDelete
    Replies
    1. Any cdma operator sim should work. I have tested it with Tata. Used 1x internet, sms & call.

      Although I am not sure if high speed internet from tata and reliance will work. Just haven't tested it yet.

      Delete
    2. i have done which u said, now i used reliance cdma sim then some msg has come in the inbox, but when i want to connect internet then it says username and password is not correct.
      what is dialing no?

      Delete
    3. access was denied because the useername and/or password was invalid on the domain.
      pls solve it.

      Delete
    4. Dialing no: #777
      try using username & password as phone number. Check your internet subscription status.

      Delete
    5. authentication error.....
      there is any another driver software for connecting internet, except ztemt-ui.....

      Delete
    6. Authentication error is not a problem with device or software.
      Contact Reliance customer care. Ask them if internet is activated on your sim. Also get the settings i.e username & password.

      Delete
    7. thanks for solve it .
      but now i want to make it any gsm bcs cdma is too costly now
      have any tricks to make it cdma to any gsm.....

      Delete
    8. CDMA to GSM not possible in this data card. Both are complete different technology.
      BSNL is the cheapest in CDMA.

      Delete
    9. is this software works in tata and others cdma data card
      bsnl cdma sim card is available in westbengal

      Delete
    10. yes, once you have unlocked using the procedure I have mentioned above, you can use any cdma sim.

      Delete
    11. if i not use any other cdma sim card then it works as a default BSNL,
      then what will be the user name and password?
      i forget the old username and password.

      Delete
    12. BSNL has different username & password for every region.
      If you used EVDO try:
      username & password: phone number with std code (remove first zero)

      Else try
      username & password: cdma

      In my region we use 165 as id and pwd.

      Delete
    13. please add driver link of EV-DO ACE87000 800M just like u add dfs link.

  7. Hi,

    Conversion of the postpaid to prepaid is off the record and not official. People who had originally purchased the AC8700 device in the BSNL EVDO postpaid plan and currently have unsubscribed can go for a prepaid plan after unlocking the device. Regarding the connection speed, I have'nt tried it in the EVDO mode as the place where I live has 1x speed. I have to try in EVDO mode when I am in roaming.

      Your zte software is fine. DFS ko close jarur kar dena before opening zte software. Pehle 'release all ports' then 'close application'.

  9. Abhi to koi nahi. Par Tata Indicom use kiya than saal bhar pehle.
    Right now using BSNL Evdo. Mere city mein hardly 10 people use EVDO. Avg. speed I get is 160-200Kbps. WO bhi 650+tax per month.

    there's a possibility tata has locked whiz sim with their data card. Sorry man cant say more till I have tried myself.

    1. Hi Shyam ji,
      I tested with Tata sim a while back and it worked. Hard to say what could be the reason as it is working with other operators. My guess is sim is locked to certain handset if it came with one. If you can arrange to test it with another tata sim to confirm.

    I tried to unlock ZTE diagnostic interface 6000. It got properly unlocked. But when I am inserting Relience CDMA sim, it is not showing any network. Many of us are facing the same problem.
    Can u please provide a solution to this ?

    1. Hi Debjyoti, I am not sure why cant you see the service port. Anyways Diagnostic port works fine too. Reliance, TATA, MTS lock their sim to mobiles/data cards purchased thru them. In some circles it works, for others it doesn't. Plus some users have reported that the new cdma sim cards are not compatible with ZTE AC8700.
      BSNL has shut down EVDO in my city due to less subscribers. My friend has taken the data card so I cant experiment more on it. Plz check forums like rimweb.in .One interesting article I found is (http://www.rimweb.in/forums/topic/32930-the-all-in-one-faq-using-foreign-imported-cdma-handsets-with-cdma-networks-in-india/).
      If I get my hands on a data card I will test the new sim cards and confirm.

    1. Hi, If you haven't solved the problem. This happens due to Hybrid Pref settings set to yes.
      Download this word file from http://www.mediafire.com/?qafdbh8g3q5qaae

      The software is embedded inside file. You will find it once you open it. Follow the basic instructions to connect your data card. Leave the last few instructions of connection software.
      Once you connect the data card. In systems menu you will find 'Hyprid Pref' option. Set that to no and your data card wont automatically shift networks.
      Do ask if you get stuck somewhere.
