How to sign up for DSJ (step-by-step)

This guide walks you through the DSJ registration flow. If you've hit an "Invalid Code" error or you're helping a new BG member sign up, start here.

Important. Always start from the link shown on AI Hawaii home. Don't type the URL from memory or from an old text. The domains rotate.

Before you start

You'll need:

• A phone number or an email you can check right now
• The referral code from whoever invited you (double-check the letters — this is the #1 source of "Invalid Code" errors)
• 5 minutes somewhere quiet

Step 1 — Open the login page

1. Go to ai-hawaii.vercel.app
2. Tap the big green Open login button. This takes you to the current DSJ domain Sony has posted.
3. On the DSJ page, tap Register (bottom of the login form).

Step 2 — Phone or email?

Pick one. Don't try to register twice with different methods back-to-back — the codes get confused.

• Phone works fine for US/VN numbers. Include the country code.
• Email is fine too. Use one you actually check. Gmail is fastest.

Step 3 — Enter the verification code

DSJ sends a 6-digit code to your phone or email. It arrives within 60 seconds.

• If you don't get the code: wait 60 seconds, then tap Resend.
• If the code still doesn't come: check your spam folder, or switch to the other method (phone ↔ email).
• Do not start a brand-new registration on a different DSJ domain while waiting. That's what breaks the code.

Step 4 — Enter the referral code

This is where most people get stuck.

• Type the code letter-for-letter. Check uppercase vs lowercase.
• Don't copy-paste from a screenshot with OCR errors.
• If your referrer sent the code in a text, ask them to send it again as text (not as an image).
• If you get "Invalid Code": pause, double-check with your referrer, retry once — not five times.

---

Step 5 — Set your password

• Use a password you'll remember. Write it down somewhere safe (Notes app, paper, password manager).
• DSJ won't let you recover it easily if you forget. Save it.

---

Step 6 — You're in

After submitting, you should land in the DSJ dashboard. First things to do:

1. Enable two-factor authentication (Settings → Security).
2. Add your email if you signed up with phone, and vice versa. This is your backup if one channel goes down.
3. Ask your referrer what to do next for your BG plan.

Still stuck?

• Open the AI Hawaii Helper — the chatbot answers common questions in English or Tiếng Việt.
• Text Sony if you've tried everything above and the code still won't work.
• If the page keeps erroring, the DSJ domain may be rotating. Come back to the AI Hawaii homepage and try another link from the list.

For referrers

If you're the one inviting someone:

• Send them your referral code as plain text, not a screenshot.
• Send them the link from ai-hawaii.vercel.app, not an old link in your history.
• If they're next to you, show them the QR code on the home screen. Fastest flow.
• Stay with them through step 4. That's the most common stumble.
