If imo is not working properly, you may experience connection issues or messages failing to send. Most issues come from network routing, VPN usage, or device settings rather than the app. These problems are usually temporary and can be fixed with a few simple checks.
How to fix imo not working (3 steps)
Start with these steps first. They cover the most common causes and usually restore normal connection.
Step 1: Check your network route
If imo is not working, start by checking your network. Switch between WiFi and mobile data to see if the issue changes. Some networks may block or limit certain traffic. If you are using a VPN, turn it off completely. Some VPNs can cause connection delays or login issues.
Step 2: Fix phone settings
Make sure imo can run normally in the background.
- Allow background data
- Disable battery optimization (set to unrestricted if available)
- Enable background activity permissions
- Set date and time to automatic
These settings allow the app to stay connected and receive messages in real time.
Step 3: Check your app version
imo is free to download and use. If you installed it but cannot search for contacts or use basic features, you may be using the wrong version.
This often happens when your app store region is set to the US. In that case, you may get a version that does not work properly with your local network.
Download imo only from the Google Play Store, the Apple App Store, or the official website, and make sure your store region matches your location.
If you still can’t connect
If the issue continues after the steps above, it is usually related to a specific function rather than a general connection problem.
Cannot log in to your account
Make sure your phone number is entered in the correct international format (for example, +7 for Russia). Repeatedly requesting verification codes can also trigger temporary limits, which may block further attempts for a period of time.

Contacts not showing
If your contact list appears empty or you cannot find people, the problem is often linked to permissions or app version. Make sure the app has access to your contacts, and reopen it after granting permission. If the issue continues, it may be caused by installing a US version of imo, which not work properly with local contacts and network settings.
App stuck on “connecting”
If the app never goes online, the connection path is likely unstable. This can happen on certain WiFi networks or when another app is modifying your network route. Switching to mobile data or restarting your router often helps restore a stable connection.
Messages sending but not delivered
If messages stay on a single check mark or fail to deliver, the connection may be dropping intermittently. Opening the app again usually forces it to reconnect. In some cases, waiting a short time before retrying is enough for delivery to resume.

App crashes or does not open
If the app crashes on launch or does not open, the issue is usually related to cached data, system compatibility, or an outdated version. Updating the app or clearing cache from system settings can resolve most of these problems.
Calls not going through
If calls fail to connect or drop quickly, the network is likely unstable. This happens more often on public WiFi, where certain types of traffic may be limited. Switching to mobile data or moving to a stronger signal area usually improves call reliability.

Final note
imo generally works normally. If something is not working, it is usually caused by connection or device settings. In most cases, checking your network, turning off VPN, and adjusting basic permissions is enough to restore normal use.
