  2. When DC unlocker claims that a particular model is unlockable,then it’s true for real,I swear that I really did unlocked my MTS Huawei EC1561 with the help of DC Unlocker.I also have got my friends free credits & I tried the same with EC315,but it just couldn’t unlock it.EC315 reverts back to NV Mode only.Anyway I atleast have unlocked my EC1561.My heartful thanks to Dc unlocker!

  3. Just to inform the EC 306 by MTS also Reverts to NV only, so only a Default firmware can solve this issue, but Firmware Flashed Data card have problem with BSNL EVDO , it connects with 1X Speed/Mode, so if some one looking for BSNL EVDO should buy ZTE AC 2766,for the time being.

    PS : my spc code for MTS EC 306 was 182300

  4. sir, when was the last time it was confirmed that a tata photon max ec306 modem was unlocked using the above method?
    I am buying one myself

  5. Dear Kamlesh

    Please let me know if I could use the same steps for MTS EC306 too.
    If you could clear my doubt it will be very grateful
    Then I will be able to decide if I buy MTS locked or MTS unlocked Ec306

  6. Dear Kamlesh,

    I have bought Huawei EC8201 EVDO device.In my country the operator does provide the CDMA 2000 data service without SIM card. So, when the sales person inserted my device to his computer the COM port cannot be detected. Can you suggest me a solution.

  7. Sir i tried this methode in my mts ec306 data card. But after data card reconnect, ruim is auto reset to nv only. please help me.

  8. When I try connecting it gives the result “the remote desktop did not respond”. Also its not showing reliance in tower symbol….its still showing CDMA2001x, even when I remove the reliance sim off, though i have given RUiM only during unlocking. One more doubt.. after unlocking I clicked close button and it asked ” do you want to send Mode Reset in order to apply changes?”, and I clicked Yes button.
    Please advice what I have to do.

    NB: when I give RUIM only it showed success in both verification 1 and 2

  9. Please tell what is the difference between these:
    1. Download version Normal setup (Installer setup.exe)
    2. Download version Update Wizard (Flasher To Modem)

    And also please tell what is:
    1. Firmware,
    2. Software,
    3. Dashboard.

    I am visiting your website regularly. But I don’t understand these technical terms. If you put these details in your website, it will be useful for all.

    Thank you in advance.

  10. Bro I bought UNLOCKED Huawei EC306 (tata photon max) Rev-B data card from ebay. It came with Mobile partner software. But unfortunately only three modes available: CDMA, EVDO & HYBRID. When I connect with EVDO (or even Hybrid), its fluctuating between Rev-A and Rev-B tower. So can you kindly suggest me any alternate software which allows me options like Rev-A, Rev-B, 1X etc.,

    For example I have seen such options with SMARTFREN and tata photon web dashboard. Kindly help me on how to use those or any alternatives to Mobile Partner.. Thanks a lot in advance..
