[Galaxy Note 3 Q&A, Help & Troubleshooting] xdaoxs:
SCL22 working with Docomo OCN MOBILE ONE PREPAID DATA SIM

Thanks FrankBrazillian and others for your input. I can confirm this has worked for me.

My aU plan on my Galaxy Note 3 SCL22 for two years expires this month. The day before I headed to Yodobashi camera in Osaka to sign up to an OCN Phone and internet plan (none of the big carriers would allow me to use my SCL22 with a SIM and phone plan, have to buy a new phone which is BS island mentality). These new companies use the same services as Docomo or aU and are half the price depending on what you choose (reality check - they are subsiduaries of the big carriers). The sales rep (young lad emotionless and apathetic) helped me out. Mentioned that the phone must be unlocked and if you are going between carriers it probably isn't. Since I unlocked my phone a year or more ago, I insisted it was okay and asked if I could test their SIM. He complied after some arm twisting. Unfortunately the SIM wasn't recognised. This was probably because two weeks ago I had to reinstall KitKat because of a catastrophic failure when tinkering with encryption settings. Came home last night and started researching and found this thread and:

http://www.neko.ne.jp/~freewing/android/au_scl22_galaxy_note3_sim_unlock/ -> its in Japanese but you can easily use an online translator to get the jist

and

I managed to unlock the phone again. I am not sure whether the download of the zip from the second link helped or whether the Secret Menu code below did the trick. Cant confirm which as I flashed the modem from the original firmware and installed the zip from above first before doing the procedure below.

[HOWTO]

1. Unblock the KeyString file with:

> /efs/FactoryApp/keystr

Change to OFF

In Keypad Type

*#27663368378#

Do the following

[1] UMTS

[1] DEBUG SCREEN

[8] PHONE CONTROL

[6] NETWORK LOCK

[2] NW LOCK NV DATA INITIALLIZ

Back

[7] NETWORK CONTROL

[1] GCF

[1] GSM/(E)GPRS/WCDMA GCF ON

Back

[2] BAND SELECTION

[1] Automatic

MAGIC!

I will head to Yodobashi again now and retest it. If I dont post again it means the phone successfully unlocked and I will be using OCN or another second hand carrier. Good luck to all.

UPDATE #1

SETUP aU SCL22 with Docomo SIM. Decided to test this with an OCN prepaid package (for short term tourists) as the Yodobashi staff memeber got sick of me and refused to let me test further. I purchased the OCN MOBILE ONE PREPAID pack (its yellow and contains 1GB of data for 3 months at high speed 3080 yen total). Heres what I did to get it going...

Firstly

with KDDI aU SIM in there

Power up your awesome SCL22 with aU SIM

In Keypad Type

*#27663368378#

UMTS → DEBUG SCREEN → PHONE CONTOROL → NETWORK LOCK

NW LOCK NVDATA IN

Repeat twice [MENU] + [BACK]

NETWORK CONTROL → GCF

Tap the GSM / GPRS / WCDMA ON.

After this it will turn off the power.

Take out the aU SIM and put a Docomo SIM.

Secondly

with Docomo SIM in there

Turn SCL22 Samsung Galaxy Note 3 ON

Go to keypad dialler and input #7465625*638*#

This enters the Network Lock Mode,

Input 0000 and push OK.

It will immediately flash a message too quick to read and it will go out of this screen, which means, the unlock was successful. Now you are ready to input the APN settings to get Docomo going (if you get any other message like unsuccessful then something went a miss so start again).

But wait theres more! (anyone from oz will remember the steak knive commercial from the 90s)

Recognising your Docomo SIM in SCL22

Other network from Settings>

Mobile network>

Roaming Settings>

System Settings>

Choose the "Overseas (LTE)".

Setting the APN

Go to Settings->More Networks> Mobile networks> Press the top right corner of the + in the APN of the screen from the setting.

In the new APN settings screen Input the following,

Name	OCN

APN	lte-d.ocn.ne.jp

Username	mobileid@ocn

Password	mobile

Mobile country code (MCC)	440

Carrier code (MNC)	10

Authentication type PAP or CHAP	CHAP

APN type	default, mms, supl, hipri, dun, tether

Bearer	LTE

Press SAVE and ENTER.

Then, like in the previous step above press *#0011# in the dial, and open the "Service Mode".

[MENU] then [BACK]

[MENU] then [Key Input],

enter Q0, the MAIN MENU opens.

ON MY SCL22 YOU PRESS THE FOLLOWING TO ENTER SERVICE MODE

In Keypad Type

*#27663368378#

From the MAIN MENU

[1] UMTS →

[1] DEBUG SCREEN →

[8] PHONE CONTROL →

[7] NETWORK CONTROL →

It will open the [2] BAND SELECTION.

[2] and select the WCDMA Band Preference → [5] WCDMA IMT2000.

[MENU] + [BACK] is repeated twice, to return to the BAND SELECTION MENU.

[4] LTE Band Preference →

After selecting the [1] LTE B1,

[MENU] + [BACK] to return to the twice repeated BAND SELECTION MENU.

[1] choose Automatic.

Again, do the following:

Then, like in the previous step above press *#0011# in the dial, and open the "Service Mode".

ON MY SCL22 YOU PRESS THE FOLLOWING TO ENTER SERVICE MODE

In Keypad Type

*#27663368378#

I had to repeat the LTE BAND PREFERENCE -> AUTOMATIC step above a second time as the network wasn't opening up.

[MENU] + [BACK] is repeated twice, to return to the BAND SELECTION MENU.

[4] LTE Band Preference →

After selecting the [1] LTE B1,

[MENU] + [BACK] to return to the twice repeated BAND SELECTION MENU.

[1] choose Automatic.

After pressing automatic twice the network opened up immediately and data was flowing freely.

I can say this was perfect on a LINE app call, YouTube video streaming and all other data functions (I had the subjective feeling it was faster than aU KDDI network service). Ok, I hope this helps others out in figuring things out.

The next step (a little risky but I have a 95% confidence interval this will work) is to sign up to either a two year plan or 6 month prepaid plan with OCN. I will most probably head to Yodobashi camera tomorrow. The first step I have been told is to go to au and make the application for MNP to transfer your number. Then quit your contract (mine ends this month so its perfect timing). Then you head to the OCN counter with you MNP paper and apply for the plan of your choice.

I will report back tomorrow as soon as I get things going with the OCN 5GB or 10GB monthly service (dont forget you need a credit/debit card!).

UPDATE #2

The Unlock doesnt hold throughoughout a reboot or shutdown BUT the good news is all you need to do is go to the setting for AUTOMATIC BAND SELECTION and click AUTOMATIC again -> then Go to keypad dialler and input #7465625*638*#

This enters the Network Lock Mode,

Input 0000 and push OK. and youre good again!

If anyone recommends a way to get it to hold let us know please. Stay tuned for confirmation whether it works on contract and Call and data SIM...

UPDATE #3

Used OOKLA Speed Test With OCN Docomo SIM 4-5mb/s download with au KDDI SIM 18-20mb/s Upload is standard 10mb/s Obviously OCN DOCOMO is slower than au KDDI. Watching Netflix movies is fine but a little fuzzy on the OCN DOCOMO prepaid. Hopefully the OCN DOCOMO plan will be faster. Stay tuned...

UPDATE #4

Went into Resona demanding a VISA DEBIT card with my current account. After some arm twisting, they complied (two years ago they refused claiming I cant have one as I already have an acvcount, lost in translation most probably!) The RESONA VISA DEBIT card should arrive withing two weeks (actually card arrived in a week!). I will post an update as to whether OCN accept it as a payment method...stay tuned

UPDATE #5

A week ago, went to Yodobashi camera MVNO section and armed with the menu unlock sequences, I went ahead with purchasing an OCN Mobile ONE package. The gentlemen at the counter were skeptical it would work but after pulling out the test SIM I purchased above (see UPDATE 1), they agrred to give it a go. First I showed them the test SIM for DATA only for tourists, and after seeing it work they pulled out their own test SIM for voice and data. After doing the update sequence in UPDATE 2 above, I could hear a lot of "SUGOI" but we still needed to test if the call function would work. I think they dialled 157 and I received a call back from DOCOMO stating that calls were working. Hence we proceeded. First had to call aU to tell them I would be stopping my current contract. They gave a special MNP number which the staff at Yodobashi used to send to OCN along with my Japanese driver's licence and RESONA VISA debit card. I went back in an hour and all was okay.

UPDATE #6

Small issue. Depending on the settings you choose, you can either:

A - > Receive calls and SMS and use internet at slow 3G speeds

OR

B -> Use internet at 4G 20Mb/sec and not receive calls (but you can call others)

Not sure why but havent hit the right settings yet.

I will post more detail as to what settings I use, maybe someone can help me figure it out. All in all super happy I could break away from locked 2 year plans. I only need to commit 6 months to OCN then I can do whatever I like. Similar service to aU and only 3240 per month compared to 8500! Reccommneded if you really wanna use this phone.
