Are you experiencing issues when making a call or when someone tries to call you?
Please follow the steps below.
Call quality can depend on several factors:
📱 Your SIM card
If you experience repeated issues, your SIM card may be faulty.
You can request a replacement SIM card at one of our stores.
Some stores are open on Sundays from 9:00 AM to 1:00 PM, including Bascharage, Bettembourg (Cactus) and Foetz (Leclerc).
📲 Your mobile phone
We recommend turning your phone off and on from time to time to reset the network connection.
📍 Your location
Call quality may vary depending on where you are, for example :
- Buildings with thick walls
- Underground parking areas
- Areas with weaker network coverage
If you have access to WiFi, you can enable WiFi Calling (VoWiFi) to improve call quality.
⚠️ Your line status
Your line may also be blocked in certain cases:
- Lost or stolen device report
- Unpaid invoice
- Insufficient credit for prepaid customers
💡 Tango tip
Try inserting your SIM card into another phone and make a call.
This will help determine whether the issue comes from your phone or the network.
