Unlock the new BOLT! 4G LTE mobile wifi mifi | Gadgets Guides | ZTE MF90

In my recent trip to Indonesia, I chanced upon the re-launch of BOLT! Super 4G LTE and a very attractive promotion with a ZTE MF90 mifi bundled with a prepaid data card for just Rp 300K (USD 26).
Closer checks, the telco BOLT! has heavily subsidized the cost of the MF90 midi modem.

It is amazing to see the claim that major parts of Jakarta are covered by the 4G LTE (2300 mhz) signal.


Without doubt, the ZTE MF90 modem is locked for BOLT!. Fortunately, it can be easily unlocked for overseas usage. It is important to verify whether the published LTE frequencies in your hometown is supported by this mifi modem. Else, the maximum connectivity could be constrained to 3G (UTMS) or 3.5G (HSPDA).

Unlocking the ZTE MF90 is quite straightforward:


STEP 1 : Download & Install DC-Unlocker client software (from https://www.dc-unlocker.com/downloads, only choose the 1057 version)


STEP 2 : Install the necessary drivers (modem, ports)



STEP 3 : Connect the ZTE MF90 modem & verify the link communications



STEP 4 : Purchase unlock credits (7 credits/7 Euro$ per unlock operation) – https://www.dc-unlocker.com/buy


STEP 5 : Unlock the ZTE MF90




STEP 6 : Reset the modem & do a restart

Reset button is located within the modem, next to the battery compartment.

STEP 7 : Flash write the dashboard (Win&MacOS generic) – https://www.dc-unlocker.com/downloads/get/wRIrWbm8


STEP 8 : Configure the necessary APN & Network settings.

The signal should reflect either in Blue (LTE mode) or in Green (non LTE mode)

    Hi, this ZTE MF90 also support LTE FDD 1800/2600 MHz right?
    Because it support multimode LTE band, FDD and TDD.
    But how we gonna force it to use FDD instead of TDD?

      The one which I obtained from Indonesia (BOLT!) only supports 2300 Mhz. Not sure if the h/w or firware limited, unless we have a tool to flash it. At the moment, there is none. If you have further luck, do share with all.

        I believe it can support more than that, because the Bolt MF90 is just rebranding from ZTE MF90 and it has no problem to use the official firmware.
        Hope got someone that can unlock the FDD band of this type of modem.

          fyi, The latest batch of BOLT! MF90 has an updated firmware which prevents dc-unlocker to unlock it.

          It will be wonderful if indeed there is a way to unlock the FDD bands as 2300Mhz is only available in Indonesia, India, China & Sri Lanka witin Asia Pac.

    I was wondering, do you know if this works in Bali ? I just bought one of these but the signal thing just keeps flashing read.

    I have activated and am on the free initial 8GB they give you . But cannot connect because that network LED is always read... any comments?

      Not sure about Bali. But I have mine working perfectly in Jakarta. Flashing red is highly due to no network (default is locked to BOLT! 4G APN). You may try to set to another Telcom network APN if there is no BOLT! coverage there. This, you will need to unlock the set.

      I live outside of Bogor which has full coverage, I could not gain access so bought an unlocked modem, which is loaded with the following version of firmware finding the firmware is not easy, ZTE do not supply it.

      Bolt do show area coverage on their webpage, it is expanding.


      I use an alternative carrier and the modem is very fast, although I cannot connet to 4G

      By default, it will auto connect to BOLT LTD if there's signal coverage. If you are using other Telford provider, you need to unlock the device and add new APN. you need to consult the telco provider on the APN settings.

      The BOLT 4G from Indonesia is network locked by default. Once you have it unlocked, you should be able to use it out of indonesia, provided the network frequecies are supported.

    Can you tell me if I can open ports on Bolt 4G? I was hoping to host a Minecraft Server over a Bolt Hot Spot or Router but wanted to make sure I can truly port forward with it.

    I have been using my bolt by huawai here in Indonesia and all was great until I saw that there was a newer firmware. From the pc to the bolt it did the download fine and installed to my Bolt the fat one, and after it was done, it reboot itself and it comes up in the bolt display Device Locked. How to fix this as I have the correct SIM from telkomsel and topped up a couple days ago, and now cant usr it. On pc says the same and says invalid sim or usim.
    Any suggestions? Its as if they dont use Telkomsel numbers anymore with the latest firmware update. I bought this last October and all good until last night. Help..

      Hi Dale,

      It sounds like your BOLT modem is sim re-locked after the update of the new firmware. That explains why the device can only be 'activated' when you use a BOLT sim card rather than the other Telco companies.

      I would suggest you to refer to https://www.dc-unlocker.com/ to get the latest version & re-unlock your BOLT modem.
