WhatsApp is the most commonly used Instant Messaging app across the globe. However, this app is not without errors, and one such error is the We Couldn’t Send An SMS To Your Number” received on WhatsApp, which does not allow users to log in to WhatsApp on their device. Today, we will help our readers fix this issue using many methods that have worked for others. Also, we will introduce the “Message To Unknown Numbers” app that will help users send WhatsApp messages to unsaved contacts.
Best Methods To Fix The “We Couldn’t Send An SMS To Your Number”
Method 1 – Reboot Phone
Experts suggest that this error on WhatsApp might be due to a temporary glitch and can be resolved by a simple restart. Just reboot the phone, use WhatsApp to resend the SMS, and check if the issue has been resolved. Otherwise, move to the next step.
Method 2 – Reinstall WhatsApp
There could be a glitch with the current installation. Hence, we suggest that you uninstall WhatsApp by long-tapping the WhatsApp icon and then tapping on Uninstall. Use the Google Play Store app to install WhatsApp.
Method 3 – Verify Your Region Code And Phone Number
WhatsApp will automatically detect your region, display the correct dialing code, and prompt you to enter your mobile number. Ensure you enter the correct number to receive the security code.
Method 4 – Verify WhatsApp’s Servers
The problem might be on WhatsApp’s side. Visit Downdetector and search for WhatsApp to see if there are any server issues. If so, you’ll need to wait for them to be resolved.
Method 5 – Toggle Between Wi-Fi And Mobile Data
A weak network connection could be the issue. Try toggling between Wi-Fi and mobile data. You can also briefly enable and disable Airplane mode on your phone to reset the connection.
Method 6 – Verify with a Missed Call or Email ID
You can verify your identity using a missed call or email ID if you haven’t received the WhatsApp security code yet. WhatsApp will place a missed call and check your call logs to confirm your identity.
Note : WhatsApp may request permission to access your call logs.
1. Open WhatsApp, enter your mobile number, and tap Next.
2. Tap Continue to verify your number.
Verification via email ID is only available if you previously added an email address during WhatsApp setup or enabled two-factor authentication. Simply choose the option to receive the code via email.
Method 7 – Install The WhatsApp Business App To Get A Code
Although this method may seem a bit unconventional, experts recommend it due to its success rate. Don’t worry, you won’t need to switch to WhatsApp Business; you’ll just use the app temporarily to resolve the issue. Once you receive the code, don’t use it on WhatsApp. Instead, return to the regular WhatsApp app and request the code again.
Method 8 – Use A Different Device To Get The WhatsApp SMS Code
Install WhatsApp on another device or add your account to an existing app. I attempted to get the code but remembered not to enter it on the secondary device. Instead, go back to the primary device and try the verification again. Hopefully, you’ll receive the security code without any issues this time.
Method 9 – WhatsApp Server Might Have Blocked Your Number
If the error occurs after multiple failed attempts, the WhatsApp server may block your device from getting the SMS. In this case, you’ll need to wait 24 to 48 hours for the block to be lifted automatically. Unfortunately, nothing can be done to speed up this process.
Method 10 – New SIM or eSIM Activated
If you’ve recently activated a new SIM or eSIM, SMS services may be temporarily unavailable. In some countries, mobile carriers impose restrictions on new SIM cards or after mobile number portability (MNP) to prevent misuse, which can prevent you from sending SMS messages.
Method 11 – Change The Network Selection To Manual From Automatic
Some experts have suggested that shifting the Network Selection from automatic to manual can help fix this issue. Follow these steps –
1. Tap on Settings.
2. Next, tap on Connections.
3. Tap on Mobile Networks.
4. Then tap on Network Operators.
5. Toggle off the button next to “Select Automatically.”
6. A list of networks will be presented. Tap on your network to select it.
Method 12 – Contact WhatsApp
If you still cannot receive the WhatsApp security code, your last option is to contact WhatsApp support for assistance.
