No Mobile Signal Indoors

- Move closer to a window or go to a higher floor — concrete walls absorb signal significantly. - Check if airplane mode was accidentally enabled. - Remove and reinsert your SIM card, then restart the phone to force a network search. - If the issue persists in a specific location, the problem may be a local coverage gap rather than a device fault.

Payment Not Going Through in the App

- Confirm your payment method is still valid and hasn't expired. - Check that your bank hasn't flagged the transaction — some banks block recurring telecom charges by default. - Try a different browser if paying through the website rather than the app. - If the page freezes at the confirmation step, the session may have timed out; reload and start the payment again from scratch.

Service info and troubleshooting

Drei App Won't Open or Crashes: If the Drei app freezes on launch or crashes immediately, the most common cause is an outdated version. Check the App Store or Google Play for a pending update. If the app is current, clear its cache through your phone's app settings and restart the device. On iOS, deleting and reinstalling the app usually resolves persistent launch failures.
Login Failing in My Drei Account: Authentication errors often come down to a mismatched password or a session that expired. Reset your password through the login screen using your registered email or phone number. If two-factor verification codes aren't arriving, check that your number is active and receiving SMS. Switching from Wi-Fi to mobile data can sometimes unblock the SMS delivery.
No Mobile Signal Indoors: Move closer to a window or go to a higher floor — concrete walls absorb signal significantly.

Check if airplane mode was accidentally enabled.

Remove and reinsert your SIM card, then restart the phone to force a network search.

If the issue persists in a specific location, the problem may be a local coverage gap rather than a device fault.
Mobile Internet Stops Working: When data cuts out despite showing signal bars, the APN settings may be misconfigured. Go into your mobile network settings and confirm the APN is set to drei.at. If it looks correct, delete it and re-enter it manually, then toggle mobile data off and back on.
SMS Messages Not Delivering: Text delivery failures usually point to network congestion or a temporary routing issue. Try sending to a different number to isolate whether the problem is recipient-specific. Restarting the phone refreshes the network registration, which clears most transient sending errors.
Payment Not Going Through in the App: Confirm your payment method is still valid and hasn't expired.

Check that your bank hasn't flagged the transaction — some banks block recurring telecom charges by default.

Try a different browser if paying through the website rather than the app.

If the page freezes at the confirmation step, the session may have timed out; reload and start the payment again from scratch.
Drei Website Unavailable or Loading Slowly: Server-side slowdowns on drei.at occasionally happen during peak hours or after deployments. Clearing your browser cache and cookies resolves stale data issues that mimic an outage. If the site loads partially or hangs on a specific page, try a different browser or device to confirm whether it's a local rendering issue.
High Ping on Mobile Data: Elevated latency during gaming or video calls is often caused by network switching between 4G and 5G towers. Manually locking your connection to one standard in your mobile network settings stabilizes the ping. Closing background apps that consume data simultaneously also reduces latency spikes noticeably.
