WhatsApp OTP Not Received Problem Step By Step Guide Follow-

WhatsApp is one of the most widely used messaging apps in the world, but sometimes users face a frustrating issue — WhatsApp OTP not received during registration or login.
If you are stuck on the verification screen and the OTP SMS or call is not arriving, don’t worry. This guide explains all possible reasons and proven solutions to fix the problem permanently.

Why WhatsApp OTP Is Not Received?

Before fixing the issue, it’s important to understand why WhatsApp OTP problems occur. The most common reasons include:

Weak or unstable mobile network
Incorrect phone number or country code
SMS blocking or DND services
WhatsApp server issues
Recently used the same number on WhatsApp
SIM card or device issues

Let’s fix each one step by step.

1. Check Your Phone Number Format Carefully

Many users miss OTP simply because of wrong country code or number format.

What to check:

Select the correct country from the list
Enter the number without spaces or extra digits
Do NOT add 0 before the mobile number
Example (India):
✅ +91 9876543210
❌ +91 09876543210

After correcting the number, tap Resend SMS.

2. Ensure Strong Network Signal (Very Important)

WhatsApp OTP requires a stable mobile network, not weak or fluctuating signals.

Try this:

Switch between 4G / 5G / 3G
Turn Airplane Mode ON for 30 seconds, then OFF
Move to an area with better signal
Avoid public Wi-Fi during verification

👉 OTP SMS often fails on poor network connections.

3. Wait Before Requesting OTP Again

If you request OTP multiple times quickly, WhatsApp may temporarily block OTP delivery.

Best practice:

Wait 5–10 minutes
Do not keep pressing “Resend SMS”
If SMS fails, use Call Me option after the timer ends

⚠️ Repeated attempts can delay OTP for hours.

4. Check SMS Blocking & DND Settings

Sometimes OTP arrives but is blocked silently.

Check these settings:

Disable Do Not Disturb (DND)
Check Blocked Messages folder
Remove any third-party SMS blocking apps
Ensure WhatsApp has SMS permission enabled

Android path:
Settings → Apps → WhatsApp → Permissions → Allow SMS

5. Restart Your Phone & Reinsert SIM

This simple step solves the issue surprisingly often.

Do this:

Turn OFF your phone
Remove SIM card
Wait 1–2 minutes
Reinsert SIM and restart phone

This refreshes your network connection with the carrier.

6. Use “Call Me” Option for OTP

If SMS OTP fails, WhatsApp provides a voice call verification.

How it works:

After timer ends, tap Call Me
You’ll receive an automated call
Note down the 6-digit code
Enter it manually

📞 This method works even when SMS fails.

7. Check If WhatsApp Is Down

Sometimes the issue is not from your side.

What to do:

Check if WhatsApp servers are down
Try again after a few hours
Avoid repeated attempts during outages

Server issues are temporary and resolve automatically.

8. Avoid VPNs & Cloned Apps

Using VPNs or unofficial WhatsApp versions can block OTP delivery.

Make sure:

VPN is turned OFF
Use only official WhatsApp from Play Store
Avoid cloned or dual WhatsApp apps during verification

WhatsApp may block suspicious IP addresses.

9. SIM Card Issues & Number Reuse

If your SIM is new or inactive, OTP may fail.

Check with your carrier if:

SMS service is active
International or service SMS is blocked
Number was recently recycled

In some cases, OTP starts working after 24 hours.
