Before getting into the subject, you may not know what we mean when we say 'data roaming' so, if you don't want the warning to appear, you should take into account what it is. We refer to data roaming or 'roaming' to the sending and receiving of data on our mobile when our local operator is outside the scope of our mobile phone. For example, if we are going to a foreign country, we have to activate data roaming or roaming if we want to talk and surf the Internet. A gesture that, not long ago, cost us a lot of money but now, within the European Union, has no additional cost.
Therefore, when we are in a foreign country and we activate data roaming, an icon will appear in the coverage area, in the notification bar. Sometimes, this annoying icon even appears while in the country itself, in rural areas or in areas close to Portugal or France, as well as in some virtual operators. To deactivate the data roaming icon in a Xiaomi terminal, we must do the following.
To disable the data roaming icon we must go to the settings of your Xiaomi phone and enter 'SIM cards and mobile networks'. On this screen we will enter ' Data roaming / Allow data roaming '. Here we can choose between always having it activated, adding application exceptions (applications that cannot use said roaming) or never having it activated.
Remember that to have data roaming you must call your operator and activate it next. This tutorial is only for when you are in your own country and the data roaming icon appears. It would be preferable to set it to 'never' since we would be within the national territory and nothing would happen if we deactivated it, but when we are within a country of the European Union it is better to leave it to 'Always' even if the icon appears.
Once we have activated data roaming in our operator, we can activate or deactivate it from our own mobile. As you have seen, it is not possible to deactivate only the roaming symbol, but it is associated with whether or not we have data roaming activated.
