How can I fix my Telegram connection problem?

How can I fix my Telegram connection problem?

To fix the Telegram connection problems on mobile data, below are 8 quick workarounds that anyone can try without much trouble.   

Restart Your Phone

Your phone may be glitching due to its software acting up, resulting in Telegram not connecting on mobile data. To fix this quickly, restart your Android phone by pressing the “Power” on the side and selecting “Restart.”

Press the “Volume” and “Side” buttons on an iPhone until you see the power menu, and drag the slider to turn it off. Now simply press the “Power” button until the Apple logo appears on the screen and the Home screen shows up.

Now, turn on mobile data, open the Telegram app, and see if it connects. 

Check Telegram and Network Provider Service Status

Telegram servers often undergo scheduled maintenance, resulting in the service going down for a bit. Telegram won’t connect during this period while using mobile data or Wi-Fi. Your only option here is to wait and let the developers fix the bugs and get the service back up. 

Checking Telegram service status

Your phone service provider might also be experiencing a temporary outage, which can be why the mobile data is not letting you connect to Telegram or other apps. 

Check Data Mode & Data Limit Settings

If you have enabled the “Data Saver” mode on your Android or “Low Data” mode on your iPhone, this can be the reason why Telegram is not connecting to its server on mobile data. The same problem occurs when the mobile data usage warning is configured on your phone.

Here’s the fix: 


  • Open  “Settings.”
  • Tap “SIM & network settings.” 
  • Tap “Data Usage.” 
  • Head to Data Usage “Settings.” 
  • Turn off the mobile data usage warning notifications.
  • Go one step back.
  • Disable “Data Saver” mode.


  • Open “Settings.” 
  • Select “Cellular” / “Mobile Data.” 
  • Verify that Telegram or other apps have not consumed your mobile data package. 

If the package is expired, top up your balance and verify the Telegram app is working fine now. You can also lift up the restrictions for the Telegram app usage on mobile data by disabling the “Low Data” mode on your iPhone under “Settings” > “Cellular” > “Cellular Data Option.”

Ensure Network Coverage

Telegram and other apps won’t work or connect on mobile data if you use your phone in a location where there are issues with your network provider signals. It can be an indoor basement or an outdoor area. 

Therefore, look at the signals on your phone’s Home screen; if you see only one or two bars, you’ve found your problem. So move a bit and see if the signals get stable or show at least three bars on the screen. 

Check SIM Card

Issues with the SIM card can also cause Telegram and other apps to malfunction on mobile data. To rule out this possibility, make sure the SIM is placed accurately in the slot. 

It is also possible the SIM is damaged; however, in this case, you’ll also experience issues with using a mobile browser on the go. When this happens, you may need to contact your SIM card provider and ask them to replace it. 

Reset APN Settings

Access Point Name (APN) provides your phone with the information needed for mobile data connection. If these settings, by any chance, are misconfigured, Telegram won’t connect. To fix this, reset the APN settings on your iPhone or Android phone with these quicks steps:


  • Open Android “Settings.”
  • Tap “SIM & network settings.”
  • Select “Access Point Names.”
  • Tap the three dots at the top-right and choose “Reset to default.”


  • Go to “Settings.”
  • Choose “Mobile” or “Cellular.”
  • Head to “Mobile or Cellular Data Network,” and then select “Reset Settings.”

Update Telegram App

An outdated Telegram app might be the reason it is not connecting on mobile data due to compatibility issues with the phone. Therefore, try updating the app and verify you can initialize communication successfully. Here’s how: 

  • Open “Play Store” on Android.
  • Open “App Store” on iPhone.
  • Search for Telegram.
  • Tap “Update.”
  • Turn on mobile data, open the Telegram app, and verify it connects this time.

Reset Your Phone

If nothing works, corrupt phone firmware can be the culprit. Your best bet, in this case, is to reset the phone and start with settings that come from the factory:


  • Open “Settings.”
  • Search “reset.” 
  • Select “Factory reset.”
  • Choose “Reset device.”
  • Enter your password.
  • Tap “Reset all.”


  • Open iPhone “Settings.”
  • Navigate to “General.”
  • Tap “Reset.”
  • Select “Erase All Content and Settings.”
Factory resetting iPhone
  • Choose “Reset” and confirm.

Wait for the factory reset process to complete, open the “App Store” or “Play Store” app and install Telegram. Next, turn on mobile data, open the Telegram app, sign in, and start sending messages to verify the fix.


In this article, we explored the possible reasons for Telegram not connecting on mobile data and a few solutions to get the app working on the go. 

Hopefully, one of the fixes worked for you, and you can now resume communication with your Telegram contacts without needing Wi-Fi access.
