There are several things to check.
1. If you are in Luxembourg
Is mobile data activated? If not:
- Switch off your mobile and switch it back on again.
- Check that the Internet logo is displayed (4G or 5G).
Important note: The Tango mobile data network uses 4G and 5G technologies. If you use an older phone, it may not be compatible with 4G. Don't worry! We recommend you consult the FAQ on this subject:
If it is not, check in the mobile settings that the operator Tango is selected by default and that mobile data is enabled:
Do you have an iPhone or iPad?
Go to "Settings".
Select "Cellular Data".
Check that mobile data is activated.
Do you have an Android smartphone or tablet?
Go to "Settings".
Select "Mobile Network".
Check that mobile data is activated.
2. If you are abroad
Your device automatically selects an available operator when you are abroad.
Has it not done so, or do you prefer another foreign network? In that case, change the network settings of your device manually.
NB: if you are entering another country or returning to Luxembourg, you are advised to let your mobile select a network automatically, otherwise you will encounter problems.
Is mobile data roaming activated? If not:
Do you have an iPhone or iPad?
Go to "Settings"
Select "Cellular Data"
Select "Options"
Activate "Data Abroad"
Do you have an Android smartphone or tablet?
Go to "Settings".
Select "Mobile Network".
Activate "Data Roaming" and "Data Enabled".
Restart your device after changing the settings.
NB: When travelling abroad, it is important to note that some remote areas, such as deserts or mountains, may not be covered by a mobile network.
What's more, it's essential to know that in some countries, the 3G network is no longer available. So even in areas with normal coverage, your phone may not be able to connect to the internet or make calls if it does not support 4G or 5G networks.
We advise you to check the compatibility of your device with the networks available in your destination country before you leave.

Tango Tip: when roaming outside Europe, the price of a call or a MB of data can be high. Remember to block your mobile data and/or set your cost limits with the My Tango application.
