Knight Online phone verification not working: which problem, which fix?
Find your error first. The table below is based on the answers in NTTGame's phone verification announcement and the verification screens; the full steps are in How to do phone verification.
| What happens | Why | What to do |
|---|---|---|
| No code arrives on your phone | In this step no code is sent to you; it's on the screen | Send the "NTTGame code" text on the screen to 5564 within 5 minutes |
| "Bu URL erişilebilir" ("This URL is accessible") | The link in the email couldn't be opened | Request a new link from the browser where you filled in the form and open it in that same browser |
| I sent the SMS but time ran out | The SMS didn't reach 5564, or arrived late | Type the text exactly, including the space, wait 5 minutes and try again |
| Can't retry after pressing Cancel | Waiting period after cancelling or leaving the page | Wait 5 minutes |
| Error -101 during SMS approval, NPoint taken | A technical issue on NTTGame's side | It's fixed; refunds for the deducted NPoint are being reviewed |
| 1/3 and a red notice after verifying | Expected | Nothing to do; the number was added |
| Knight ICS shows as off after SMS approval | A display issue reported to NTTGame | If you can log in with OTP, wait; NTTGame said it will check it |
| "Already used on 3 accounts" in SMS approval | The number was used for SMS approval on 3 other accounts | Use another number, or open market and trade with premium |
Why isn't the phone verification code arriving?
Because in this system the code isn't sent to you. After you press VERIFY the screen shows three things: the callback number (5564), the code (example: NTTGame 41938) and the phone you entered as the sender. You text the code from that phone to 5564, typing "NTTGame", a space, then the code. From a foreign number the destination is +16315401700. You have 5 minutes, and if the SMS doesn't come from the number you entered, it won't match.

Don't confuse this with SMS approval. In the SMS approval for market and trade the code really is texted to you and it costs 5 NPoint; details in How to enable trade: SMS approval.
How do you fix the "Bu URL erişilebilir" (URL is accessible) error?
This message shows up when you click the PHONE VERIFICATION link in the email. The verification form says it plainly on the first screen: account updates must be completed in the same browser. If you open the link from your phone's mail app or a different browser, the process may not continue. Go back to the browser on your computer where you filled in the form, request a new link with your ID and password, and open the email and the link in that browser.

SMS verification error -101 and deducted NPoint
Some players got error -101 ("Doğrulama Kodu gönderimi başarısız", verification code sending failed) during SMS approval under Game Services, with 5 NPoint taken on every attempt. NTTGame said the technical issue is fixed and that it is reviewing and refunding the NPoint spent by mistake. If you haven't got yours back, open a ticket on NTTGame's support site with the date and amount, and don't keep retrying and spending more NPoint.
Phone verification fails with a foreign number
Foreign numbers send the code to +16315401700 instead of 5564. That's a US number, so your carrier may charge for international texts; check the text and the number before sending again after a failed try. If the SMS doesn't arrive and time runs out, open a support ticket rather than retrying over and over. NTTGame's verification email also points to support.nttgame.com for connection problems.
I verified my phone. Can I enter the new servers now?
Verification alone isn't enough. To enter the new servers you also need the pre-registration that starts October 15 and OTP enabled on your account. The sign-up steps are in How to pre-register for the new servers, and OTP login errors in Knight Online OTP error: OTP is not active, TimeSync and can't join a new server.
