No second tick.
Nothing but silence.
This happened to me during a very important talk. I sent a message, waited a few minutes, and then refreshed WhatsApp over and over again, but the message still didn't go through. I thought the other person was ignoring me at first. I figured out later that the problem was mine.
It can be stressful and confusing when WhatsApp messages don't go through. This is especially true when you don't know if the problem is with your internet, the app, or the other person's phone. The good news is that most of the time, this problem is easy to fix.
Let's take it apart slowly and in a way that makes sense.
Why WhatsApp Messages Don't Always Go Through

Issues with the Internet Connection
WhatsApp is only functional when your internet is operational. Messages won't send or receive if your connection is poor or keeps dropping.
- Wi-Fi is off or erratic: Verify that your signal is strong. To make sure the internet is functioning properly, try opening a different app or website.
- Mobile data is limited or disabled: Verify that your data balance hasn't run out and that mobile data is enabled.
- Airplane mode is on: it can occasionally be accidentally activated. All network connections are immediately cut off in airplane mode.
- Problems with the recipient's phone;
- Sometimes your phone isn't the issue at all.
- Their phone is off: WhatsApp won't be able to deliver your message if the recipient's phone is off.
- No internet on their end: They require an active internet connection, just like you do.
- You might be blocked: your messages will remain on one grey tick and never be delivered if you are blocked on WhatsApp.
- Outdated WhatsApp version: Delivery problems may arise if the other user is utilizing an extremely outdated version of WhatsApp.
Problems with the WhatsApp App or Phone Settings
WhatsApp can be silently blocked by specific phone settings.
- Older version of WhatsApp: Using an out-of-date app may result in bugs and issues with message delivery. Keep WhatsApp updated at all times.
- Data saver or battery saver modes: may prevent WhatsApp from syncing messages and restrict background activity.
- Incorrect time and date settings: For WhatsApp to function correctly, the time and date must be set correctly. Errors in sync can be caused by incorrect settings.
- Full phone storage: WhatsApp may not function properly when the storage is full.
- Although it is uncommon, WhatsApp servers can occasionally experience outages. Messages won't deliver for anyone when this occurs, and they typically resolve themselves fast.
Step-by-Step Solutions for Fixing WhatsApp Not Delivering Messages
1. First, make sure your internet connection is working.
Start Chrome or any other browser.
Try to get to a website.
WhatsApp won't work either if it doesn't load.
Change between:
- Wi-Fi
- Data on the go
For 10 seconds, turn on airplane mode and then turn it off.
This makes your network connection new again.
2. Restart Your Phone
It sounds simple, but it works.
Restarting fixes temporary problems with the network and background.
Many times, all I had to do to fix WhatsApp delivery problems was restart it.
3. Check WhatsApp Background Permissions
This step is very important.
Go to Settings, then Apps, then WhatsApp, and then Battery.
Set the battery usage to "Unrestricted" or "Allow background activity."
Also look at: Settings > Apps
Using data
Allow data in the background
WhatsApp gets more reliable after this.
4. Disable Data Saver Mode
Background apps can be blocked by data saver. Go to Settings, Network Data Saver, and disable it, and then try WhatsApp again.
5. Update WhatsApp App
Old versions can cause message delivery issues.
Open Play Store or App Store
Search WhatsApp
Update if available
I once faced delivery issues for two days because my app was outdated.
6. Clear WhatsApp Cache (Android Only)
This is safe and effective.
Go to Settings
Apps
WhatsApp
Storage
Clear Cache
Do NOT clear data unless you want to log out.
Cache buildup can slow down message syncing.
7. Check Date and Time Settings
A wrong date and time can break WhatsApp sync.
Go to Settings
Date & Time
Enable automatic date and time
This small setting fixes many hidden issues.
8. Check If WhatsApp Is Down
Sometimes the issue is global.
Search online or check social media to see if WhatsApp is facing outages.
If servers are down, all you can do is wait.
Why Messages Deliver Late Sometimes
Late delivery doesn’t always mean a problem.
Possible reasons:
- Weak internet signal
- Power-saving mode
- Background restrictions
- Phone sleeping aggressively
Once I removed battery optimization for WhatsApp, late messages stopped completely.
FAQs
One tick means the message was sent but not delivered. The recipient may be offline, or your internet connection may be unstable.
Can battery saver affect WhatsApp message delivery?
Yes. Battery saver can restrict background activity, causing delayed or undelivered messages.
If messages stay on one tick, the profile picture disappears, and you can’t see last seen, you may be blocked.
Conclusion
While Android Facebook crashes are annoying, most crashes have easy fixes. To begin, update your Android OS and the Facebook app, clear the cache, and free up storage space. Frequently, restarting your phone fixes short-term issues. If crashes continue, try reinstalling the app, resetting the app's preferences, or using Safe Mode to find conflicts with other apps. Back up your data and think about doing a factory reset as a last resort. These steps typically prevent crashes and restore Facebook's functionality.
