Please tell us some basic information before asking for help:

  1. Model Name: ASUS_I005DA
  2. Firmware Version:
  3. Rooted or not: No
  4. Frequency of Occurrence: N/A
  5. APP Name & APP Version (If your issue relates to the app): N/A

In addition to information above, please also provide as much details as you can, e.g., using scenario, what troubleshooting you've already done, screenshot, etc.



I am trying to get information about my Rog Phone 5's cellular network, I checked spec page in but looks like there are many versions from A to H but I don't know which one mine is. Is there any way to find out which one is mine because I couldn't find any relevant information in the FAQ.

I live in Japan, I have KDDI/au cellular operator, I moved my SIM card from my old phone to the new one, I was able to get cellular data working but unable do phone calls, I get "Mobile network not available" when trying to call someone. I went to operator they checked my SIM card and plan validity they confirmed that everything is working fine from their part, so I thought it's possibility the incompatibility between my Rog Phone and their network.

Can Someone help me solve this issue please.

    I have this information for KDDI au (Did we check that the Rog phone 5 is approved for them?)

    This carrier only accepts approved devices on its network.

    Even if a device supports some or all of the required frequencies for this carrier, it will not be able to connect unless the device is approved for this network. Check with the network operator to confirm whether a device is approved or not.

    There is no such restriction for NTT Docomo and Softbank

    there is no way to verify the A-H version of your phone by a user. Only Qualcomm has software to check the modem and full frequencies, a user can just see the active frequency bands.

    But for this specific case of telephony that does not work with KDDI, it would be useful to do a test by inserting an NTT Docomo or Softbank SIM in your rog 5

    Note: FCC ID is only required in the United States, the rog phone 5 for this country must be the FCC ID MSQ-I005D / I005DC

    For other countries it may be the last letter of ASUS_I005D written on the box which could indicate the model of the frequency bands, example France, ASUS_ID005DA

  • Check it with cpu z

  • Hello,

    I005DA is compatible in Japan,

    KDDI uses voice telephony exclusively in VoLTE

    it should use CDMA2000 but it seems that it is already stopped (this was planned in 2022)

    You will have to get closer to Asus support to find out if it is VoLTE compatible with Japanese operators, but I'm afraid I already know the answer :(

    search with google "at the OPEN DEVICE DEVELOPER SITE"

    The ROG 5 is well KDDI approved but I don't know how the telephony was tested !!, it is in the 5G list but not in LTE

  • Thank you everyone for your reply

    I checked a Softbank SIM card, I was able to make phone calls and connect to internet using cellular data. A website I checked confirms the compatibility with Softbank network. however I am not sure about this information.

    For other countries it may be the last letter of ASUS_I005D written on the box which could indicate the model of the frequency bands, example France, ASUS_ID005DA

    So since my phone's model number ends with "A" then my network version is "A", is this correct?

    I checked using CPU-Z as recommended by Lord_messi but it doesn't provide any relevant information.

    On the other hand I checked a website about Rog phone 5 compatibility with KDDI/au network, it shows that 2g is not compatible as you can see from the image. However I am not sure if this information is correct or not.

  • I cannot confirm 100% that the last letter of the model is the frequency but I005DA is indeed the one that uses version A frequencies, and it is the most complete in frequency; it must also be called Global version.

    I also don't see the connection with CPU-Z :)

    N79 used by NTT DOCOMO is missing but otherwise it looks correct

    Softbank and NTT DOCOMO use 3G for voice

    Rakuten Movile only uses VoLTE so the Rog 5 must also be incompatible

    KDDI au uses CDMA 1 for voice but stops this service gradually to stop definitively in March 2022 (search document "KDDI to End CDMA 1X WIN Service" to use VoLTE)

    If ASUS does not make Rog 5 compatible with VoLTE, you only have 2 choices left, resell it or change operator for NTT DOCOMO or Softbank

  • Thank you for your support for this case. I hope Asus will add support to Rog Phone 5 in the near future, this way I will have more choices.

    @FunBike31 @CraCKerO Just wanted to clear up some confusion regarding model names and versions.

    Scroll down to the network section detailing 5G bands:

    ASUS_I005DA = Version F and H in the 'Network Standard' section. (Also version G, which is the Tencent version intended for the Chinese market.)

    ASUS_I005DC = Version D in that same breakdown. This is the model with the most frequency bands. (And also the one we're selling in JP if I'm not mistaken.)

    @CraCKerO I'll try to get back to you regarding VoLTE status for Japanese operators. 🙂

  • @Gustav_ASUS

    Thank you for your intervention, it is really useful even if the correspondence with versions A, B, C, E are still unknown we could have searched without ever finding.

    Fortunately @CraCKerO is in Japan and the 4G and 5G bands used in Japan are present on its I005DA model which should have been I005DC

    One last thing, is it possible to identify the version of the bands with the information given when ordering? because ASUS_I005Dx is only on the box and never appears anywhere

    ZS673KS-1A029FR, Part Number - 90AI0051-M00320

    ZS673KS-1A046ID, Part Number - 90AI0051-M00550

    @FunBike31 Sorry for the low response rate, I'm still playing catch up after the vacation period.

    Versions A, B and C correspond to the Ultimate version, where:

    Version A and B = ASUS_I005D, version B is for the US which does not have band 40.

    Version C = ASUS_I005DB, Tencent version intended for the Chinese market.

    Versions D through H correspond to the standard ROG Phone 5, where:

    Version D and E = ASUS_I005DC, version E is for the US which does not have band 40.

    Versions F, G, H = ASUS_I005DA, version G is the Tencent version intended for the Chinese market.

    Hope that clears things up for you. Let me know if you have any more questions!

  • @Gustav_ASUS

    Thanks, the delay is not a problem for question like that, and Asus has clarified the versions / countries on the new 5s as you can see on the https site below

    But there's something wrong in my opinion

    For Indonesia there is only one active band N40 (2300) and the next ones will be N1,3,5,8

    Except here is what we read for the C version

    C version: (EMEA, RU, APAC, HK, IN, ID, BR)

    5G (Bands N1, N3, N7, N8, N20, N28, N38, N41, N77, N78, N79)

    ID is Indonesia? there is not the N40 and the N5 is missing

  • @FunBike31 Yes, ID should refer to Indonesia. Let me check and get back to you.
