"IPhone XS" released on September 21st. Since the author made a new contract at the docomo online shop, it was not possible to obtain the release date. It arrived on September 23, the day after the release.
I put the iPhone XS of Nengan in his hands!It arrived on the middle day of the three consecutive holidays. Attach the film or case you bought in advance at home and transfer the data from "iPhone 7" via iTunes. The advantage of iPhone is the ease of data migration.
Data migration is complete.It may look like an "iPhone X" with the help of the wallpaper, but it's a decent iPhone XS.Can't connect to "docomo Wi-Fi"?
After completing the setup, take the freshly grated iPhone XS and move to the station closest to your home. I tried to save data traffic by connecting to "docomo Wi-Fi" until the train arrived, but I couldn't connect to the docomo Wi-Fi access point even though I was waiting.
The author tried to connect to the SSID (access point name) "0001docomo". Since this SSID supports authentication using a SIM card, you should be able to connect without any preset settings.
I thought "Did you forget about 0001docomo?", And when I selected 0001docomo from "Wi-Fi" in the settings, the ID / password input screen that did not appear on the previous iPhone appeared.
ID and password input screen not seen on "iPhone X" or iPhone 7Looking at the "HUAWEI P20 Pro HW-01K" that I carry with me, I can see that it is firmly connected to the 0001 docomo.
Even if you exchange SIM cards with each other and try it, the result is the same. Only the iPhone XS will display the ID and password input screen.
iPhone XS is useless, HW-01K is OK. Both SIM cards (lines) have a contract for docomo Wi-Fi ...It means that there is an "abnormality" in the iPhone XS, not the access point or the server for SIM authentication.
Inquire on the Web → You will be prompted to call
After that, I tried all possible measures such as resetting the network settings, but it did not lead to 0001docomo ....
Perhaps you can connect by entering the docomo Wi-Fi user ID and password on the ID and password input screen. Or if you can accept web authentication, connecting to "0000 docomo" will solve the problem (for the time being). However, that will leave you unable to perform SIM authentication, which you should be able to do.
Therefore, I decided to summarize the current symptoms and the countermeasures I have taken so far in a sentence of 1000 characters or less and contact DoCoMo on the Web.
Then, I got a reply like this (partially omitted before and after, and the appearance is arranged).
Apparently there is something I can't tell by email.
(Part of) the reply email that actually arrived.I want you to contact the telephone counter (docomo information center)Inquiry by phone → I was told how to solve it
The day after receiving the e-mail reply, I made time to call the docomo Information Center (telephone counter).
Immediately connect with the person in charge and report the symptoms. Then, he said, "I will find out if there is a solution that I can guide you," and it was put on hold for a while.
Two minutes after the hold, the person in charge told me the following procedure, "I want you to operate as you say now."
- Open "Mobile Communication" in the settings
- If "Mobile Communication Plan" is blank, tap it
- Tap "Continue" when the "Mobile communication usage and plan" screen appears.
- Enter the network security code of the SIM card (contract line) and tap "Next"
- After reading all the notes, tap "Agree"
- Tap "Close" when the consent completion screen appears
- When you return to the mobile communication screen, check that the contracted packet pack name appears in the "Mobile communication plan".
- Turn off the iPhone and turn it on again (restart)
- After restarting, select "0001 docomo" in "Wi-Fi" in the settings.
When this procedure is completed, the name of the contracted packet pack (in the case of a shared child line, the packet pack contracted for the representative line) will be displayed in the "Mobile communication plan" field that was empty. It is quite convenient because the used capacity of the share pack will also appear in "Usage status".
The blanks are filled !!However, I don't know if this will connect to docomo Wi-Fi. Tell the person in charge "If you can't connect, I'll contact you again", hang up, and restart your iPhone XS.
After restarting, I terrifiedly connected to 0001docomo ...
connected!!I was able to connect immediately. It's as if it was a lie until now. I cannot thank the operator in charge.
"Understanding the phenomenon" does not grasp the root cause
For the time being, after making the above settings, I can now connect to 0001docomo without any problems.
On the other hand, when I search the Web, I see other events where the iPhone XS (or iPhone XS Max) cannot automatically connect to 0001docomo. However, the official website of docomo Wi-Fi does not contain any explanation such as "The automatic connection of 0001docomo may not be available on iPhone XS / XS Max".
So, when I asked the DoCoMo Public Relations Department about this event, I got an answer, so I will post it in a format (the answer is as of October 3).
--The iPhone XS / XS Max may not be able to perform SIM authentication for "0001 docomo" and the ID and password input screen may be displayed. Does the department in charge know about this matter?
Docomo Public Relations Department The chief department of docomo Wi-Fi is aware that there are some such voices. However, since the conditions and causes of the event have not been identified, we are still investigating.
――Do you not announce this event on the docomo Wi-Fi website?
DoCoMo Public Relations Department As I mentioned earlier, the conditions and causes of the event have not been identified at this time, so we have not made it known.
――When I tried the method guided by the docomo Information Center, SIM authentication to 0001docomo became possible. Is this a formal procedure?
This method is not mentioned as a countermeasure in the main department of the DoCoMo Public Relations Department (docomo Wi-Fi). I haven't been able to confirm why I was able to connect.
It seems that the stance of identifying the cause of this event and notifying it as soon as a reliable solution is found.
Anyway, if you are having trouble with "docomo Wi-Fi SIM authentication is not possible with docomo's SIM card!", Try "Load mobile communication plan" as a temporary solution.
Note!
This article was created based on the situation as of October 3rd. Therefore, "iOS 12.0.1" released on October 9th is not taken into consideration.
People who say "the situation hasn't changed after updating the OS" should also try this method.
