La itinerancia de datos está apagada.

Because itinerancia is a feminine singular noun, so it takes the feminine singular article la.

• la itinerancia
• not el itinerancia

Even though datos is plural, the main noun in the phrase is itinerancia, so that is what controls the article.

This is a noun phrase built like noun + de + noun, which is very common in Spanish.

• itinerancia = roaming
• de datos = of data / data-related

So itinerancia de datos is the standard technical way to say data roaming.

Spanish often uses this structure where English might use one noun directly before another:

• tarjeta de crédito = credit card
• centro de salud = health centre
• itinerancia de datos = data roaming

It is common in phone settings, mobile network information, contracts, and other technical contexts. It sounds more formal and technical than everyday conversation.

In Spain, many people would also understand or even say roaming, especially in casual speech or when talking about mobile phones. But on a device interface, itinerancia de datos is perfectly normal and natural.

Because apagada describes the current state of the setting, not a permanent characteristic.

Spanish usually uses estar for states or conditions, especially when something is:

• on/off
• open/closed
• connected/disconnected
• activated/deactivated

So:

• está apagada = it is turned off

Using ser here would sound wrong, because the sentence is not describing what data roaming is by nature; it is describing its current status.

Because the adjective must agree with itinerancia, which is feminine singular.

• la itinerancia → feminine singular
• therefore apagada → feminine singular

This agreement happens even though datos is masculine plural, because datos is only part of the de phrase. The main noun is still itinerancia.

Yes, apagar literally means to switch off or to turn off, and Spanish extends that idea to many settings and functions.

So in interfaces, apagado/apagada can be used for things like:

• Wi‑Fi
• Bluetooth
• mobile data
• roaming

It may sound a little broader in Spanish than in English. In English, we might prefer disabled or turned off depending on the context, but Spanish often uses apagado/apagada quite naturally.

Yes. Desactivada is also very natural and is often used in menus, settings, and technical language.

There is a slight nuance:

• apagada = off
• desactivada = deactivated / disabled

In many phone-setting contexts, both work well. A device may choose one or the other depending on the style of its interface.

Because Spanish usually treats data in this context as datos, a plural noun.

So:

• dato = a piece of data
• datos = data

That is why the fixed expression is itinerancia de datos, not itinerancia de dato.

Because the subject of the sentence is not datos. The subject is the whole phrase la itinerancia de datos, and its head noun is itinerancia, which is singular.

So the verb agrees with itinerancia:

• La itinerancia de datos está...

not with datos.

The same thing happens in English too:

• Data roaming is off
• not Data roaming are off

The normal, neutral order is:

• La itinerancia de datos está apagada.

That is the standard way to say it in a menu, notification, or statement.

Spanish word order can be flexible in some contexts, but here this version is the most natural and straightforward. Reordering it would usually sound marked, poetic, or unnatural for a phone setting.

Yes, especially in a technical or interface context. It sounds like the kind of sentence you would see on:

• a mobile phone
• a network settings screen
• a carrier message
• a system notification

In casual conversation, people in Spain might also say things like:

• Tienes la itinerancia de datos apagada.
• El roaming está desactivado.

But the original sentence is completely natural for standard written Spanish used in Spain.
