The quick checks (one minute)
- Look at the number on screen. Many failed codes go to a mistyped number or the wrong country code. If the app shows the number it is texting, read every digit.
- Check your signal. SMS needs mobile network, not Wi-Fi. One bar is enough, no bars is not. Step near a window or outside.
- Toggle airplane mode. Turn it on for ten seconds, then off. This makes the phone reconnect to the tower and often releases stuck messages.
- Wait out the resend timer. Pressing resend again and again can trigger a temporary block. Let the countdown finish, then ask once.
Where the message may be hiding
- Spam and unknown-sender folders. Google Messages can move codes into Spam & blocked. On iPhone, if Filter Unknown Senders is on, look under the Unknown Senders or Transactions list.
- A blocked sender. If you ever blocked or reported an app's messages, its codes are blocked too. Check the blocked list in your messages app and unblock it.
- The other SIM. On a dual-SIM phone, the code goes to the number registered with the app. Make sure that SIM is active and allowed to receive SMS.
- Email instead of SMS. If the app sends codes by email, check Spam, Promotions and Updates folders, and search your mail for the app's name.
When it is the network or the account
- Roaming or a new SIM. Some senders cannot reach numbers that are roaming abroad or that were activated very recently. A call-based code, if the app offers one, often gets through when text does not.
- Do Not Disturb and message blocking on your plan. Phone settings and network-level blocking options are meant to stop promotions, but an over-strict setting can catch other texts too. Review them in your phone and in your mobile operator's app.
- A temporary lock on the account. After many requests, apps often pause codes for a while to stop abuse. Wait before trying again, then contact that app's support through its own app or website if it continues.
What not to do while you wait
- Do not install a “code reader” or SMS-forwarding app that someone recommends in a chat. Those can send your codes to a stranger.
- Do not ask a friend to receive the code for you on their number.
- Do not reply to messages that offer to “speed up” your OTP. Real support never needs your code.
If you suspect someone is requesting codes for your number, switch to the account safety checklist. If the code arrives but the app still refuses you, the sign-in errors guide is the next stop.
And while the timer runs down, there is always a vault to open on Daman Login: no code required.
