डेटा अनलिमिटेड है।

Because this is very common in modern Hindi, especially for technology, phones, and mobile plans. Both डेटा and अनलिमिटेड are loanwords used in everyday speech.

In theory, you could use more Sanskrit-based words, but in real life people very often say things like:

• डेटा
• अनलिमिटेड
• प्लान
• नेट
• रीचार्ज

So डेटा अनलिमिटेड है। sounds natural in a telecom or everyday context.

It is usually pronounced roughly as ḍe-ṭā.

A simple English approximation is:

• डे = like day
• टा = taa, with a retroflex t sound

So: ḍeṭā

This is the Hindi pronunciation of the borrowed word, not necessarily identical to every English pronunciation of data.

It is pronounced approximately an-li-mi-ṭeḍ.

A rough breakdown:

• अन = an
• लि = li
• मि = mi
• टे = ṭe
• ड = ḍ

Hindi speakers usually pronounce borrowed English words in a Hindi sound system, so it will not sound exactly like all English accents of unlimited.

The structure is:

noun + adjective/predicate + है

So:

• डेटा = data
• अनलिमिटेड = unlimited
• है = is

This is a very common Hindi pattern:

• पानी ठंडा है। = The water is cold.
• कमरा साफ़ है। = The room is clean.
• डेटा अनलिमिटेड है। = The data is unlimited.

है is the present-tense form of to be for a singular subject in standard Hindi.

Here it means is:

• डेटा ... है = Data ... is

Without है, the sentence may sound incomplete in normal standard speech, although in ads, headlines, or casual speech it can sometimes be dropped.

Because डेटा is being treated as a singular or mass noun here.

Hindi often treats things like data, water, milk, etc. as a singular mass:

• पानी ठंडा है।
• दूध अच्छा है।
• डेटा अनलिमिटेड है।

You would use हैं with a plural subject, for example:

• ये प्लान अच्छे हैं। = These plans are good.

So in this sentence, है is the natural choice.

Usually no. Since अनलिमिटेड is an English loan adjective, it is normally treated as indeclinable in Hindi. That means it stays the same instead of changing like many native Hindi adjectives do.

For example, a changing adjective:

• अच्छा प्लान
• अच्छी सुविधा
• अच्छे प्लान

But with अनलिमिटेड, speakers typically keep it unchanged:

• अनलिमिटेड डेटा
• अनलिमिटेड सुविधा
• अनलिमिटेड प्लान

So अनलिमिटेड does not usually behave like अच्छा / अच्छी / अच्छे.

Hindi normally does not use articles like English a, an, and the.

So Hindi can simply say:

• डेटा अनलिमिटेड है।

Depending on context, this could correspond to English as:

• The data is unlimited
• Data is unlimited
• Your data is unlimited
  if the context makes that clear

Hindi relies much more on context than English does for this kind of thing.

Grammatically, this sentence is a full statement:

डेटा अनलिमिटेड है। = The data is unlimited / Data is unlimited

If you want the phrase unlimited data by itself, without making a full sentence, you would just say:

• अनलिमिटेड डेटा

So:

• अनलिमिटेड डेटा = unlimited data
• डेटा अनलिमिटेड है। = the data is unlimited

Yes, but it means something slightly different in emphasis.

• डेटा अनलिमिटेड है। = The data is unlimited.
• अनलिमिटेड डेटा है। = There is unlimited data / It is unlimited data, depending on context.

The original sentence puts डेटा first as the topic and then says something about it. That is the most straightforward way to say The data is unlimited.

Most commonly, it sounds like something from:

• a mobile plan advertisement
• a telecom offer
• a recharge/package description
• a discussion about internet service

For example:

• इस प्लान में डेटा अनलिमिटेड है। = In this plan, the data is unlimited.
• हमारे नए पैक में डेटा अनलिमिटेड है। = In our new pack, the data is unlimited.

So while the grammar is simple, the most natural real-world context is usually phone or internet service.

A natural way would be:

• मेरा डेटा प्लान अनलिमिटेड है।

You could also hear:

• मेरा प्लान अनलिमिटेड है।
• मेरे प्लान में अनलिमिटेड डेटा है।

These are slightly different in focus:

• मेरा डेटा प्लान अनलिमिटेड है। = My data plan is unlimited.
• मेरे प्लान में अनलिमिटेड डेटा है। = My plan has unlimited data.

It is grammatically fine, but the vocabulary is modern, everyday, and somewhat commercial rather than formal-literary.

Because it uses loanwords, it sounds natural in:

• conversation
• advertising
• tech talk
• telecom usage

So it is very normal Hindi, just not especially traditional or literary in style.
