Is the Telegram app not working on mobile data on your iPhone? While troubleshooting this problem, you should definitely connect the iPhone to a Wi-Fi and check whether the Telegram app is working or not. If you can use the Telegram on Wi-Fi, then the problem lies in the Telegram app settings.
Fix 1 – Allow the Telegram app to use mobile data
The most basic reason why this is happening is because the usage of cellular data is prohibited to the Telegram app.
Step 1 – The only way you can fix this is to open the Settings.
Step 2 – Open up the “Mobile Service” settings.
Step 3 – In the Mobile Service page, find the apps section. Tap “Show All” button there to load the list of apps.
Step 4 – Next, find the “Telegram” app and toggle that to On mode.
Once you have allowed the Telegram app access to the mobile services, you can use the Telegram app using mobile data.
So, turn on the mobile data and try to send a message in the Telegram app.
Fix 2 – Turn off the Low Power Mode
Apple can restrict the background activity of the Telegram app using the mobile data, if the iPhone is in low power mode.
Step 1 – Load the iPhone Settings and open up the “Battery” settings.
Step 2 – Turn off the “Low Power Mode” in there.
After turning off the Low Power Mode, using the Telegram app (even while it is running in the background) in the mobile data should not be a problem anymore.
Fix 3 – Update the Telegram app
Using the latest version of the Telegram app can fix the problem.
Step 1 – Load up the App Store.
Step 2 – In the top-right corner of the App Store, tap the Apple ID profile picture.
Step 3 – You can find all the apps that are pending updates there.
Step 4 – Find the “Telegram” app there and update it.
Once you have updated the Telegram app, the problem with running the Telegram app using mobile data should be gone.

Step 3 – Find the “Data and Storage” option.
Step 4 – Later, touch the “Using Cellular” feature.
