अनलिमिटेड डेटा पैक न केवल डेटा, बल्कि एसएमएस भी देता है।

This is a very common Hindi correlative structure meaning not only ... but also ....

So:

• न केवल डेटा = not only data
• बल्कि एसएमएस भी = but also SMS

In full, न केवल X, बल्कि Y भी means:

• not only X, but Y too
• not just X, but also Y

This is the most important grammar pattern in the sentence.

In Hindi, भी means also / too / as well, and it usually comes after the word or phrase it emphasizes.

So:

• एसएमएस भी = SMS too / SMS also

That is why the sentence says:

• बल्कि एसएमएस भी देता है

not usually:

• बल्कि भी एसएमएस देता है

The भी highlights that SMS is an additional benefit.

The verb agrees with the subject, which here is अनलिमिटेड डेटा पैक.

The head noun is पैक, which is treated as:

• masculine
• singular

So the verb is:

• देता है = gives (masculine singular)

If the subject were plural, you would expect something like:

• डेटा पैक ... देते हैं

If the subject were feminine singular, you would get:

• ... देती है

Many borrowed nouns in Hindi get assigned a gender, and पैक is commonly treated as masculine in everyday usage.

That is why speakers say:

• यह पैक अच्छा है
• यह पैक डेटा देता है

and not normally:

• यह पैक अच्छी है
• यह पैक डेटा देती है

With loanwords, gender is often based on common usage rather than a strict rule, so this is something learners usually have to absorb from exposure.

Because डेटा and एसएमएस are direct objects here, and in Hindi direct objects do not always take को.

In this sentence:

• डेटा देता है = gives data
• एसएमएस भी देता है = also gives SMS

Using को here would sound unnatural in normal usage.

Very roughly:

• को is often used with people, specific animate objects, or for special emphasis.
• For general things like data, SMS, books, food, etc., Hindi often leaves the object unmarked.

So डेटा and एसएमएस appear without को.

Because the two instances of डेटा do different jobs.

1. डेटा पैक = the name/type of the product

   • a data pack

2. डेटा later in the sentence = the thing it provides

   • data

So the meaning is basically:

• A data pack gives not only data, but also SMS.

Even though डेटा appears twice, it is not redundant in Hindi, because the first is part of the compound noun डेटा पैक, and the second is the object of देता है.

They are mostly English borrowings written in Devanagari, and this is extremely common in modern Hindi, especially in technology, telecom, business, and advertising.

So:

• अनलिमिटेड = unlimited
• डेटा = data
• पैक = pack
• एसएमएस = SMS

This kind of mixed Hindi is very normal in real life. Learners will see it a lot in ads, mobile plans, customer service messages, and online language.

Yes. A very common alternative is:

• अनलिमिटेड डेटा पैक सिर्फ डेटा ही नहीं, बल्कि एसएमएस भी देता है।

This also means:

• The unlimited data pack gives not only data, but also SMS.

Both patterns are natural:

• न केवल ... बल्कि ... भी
• सिर्फ ... ही नहीं, बल्कि ... भी
• केवल ... ही नहीं, बल्कि ... भी

They are close in meaning, though न केवल can sound a bit more formal or polished.

Yes, Hindi word order is flexible, though some orders sound more natural than others.

The original sentence:

• अनलिमिटेड डेटा पैक न केवल डेटा, बल्कि एसएमएस भी देता है।

is natural and clear.

You could also hear:

• अनलिमिटेड डेटा पैक न केवल डेटा देता है, बल्कि एसएमएस भी देता है।

This version repeats the verb in both parts and may sound even clearer to learners.

Hindi often allows some movement of phrases for emphasis, but the key structure must stay recognizable:

• न केवल X, बल्कि Y भी

That pattern is what ties the sentence together.

A rough pronunciation guide is:

• analimiṭeḍ ḍeṭā paik na keval ḍeṭā, balki es-em-es bhī detā hai

A more natural chunking would be:

• अनलिमिटेड डेटा पैक | न केवल डेटा, | बल्कि एसएमएस भी देता है।

A few pronunciation notes:

• डेटा is usually said like day-taa
• पैक sounds like paik
• एसएमएस is said letter by letter: es-em-es
• भी has a long ee sound
• देता has de
  • taa

Hindi does not use articles the way English does.

So where English says:

• The unlimited data pack
• An unlimited data pack

Hindi can simply say:

• अनलिमिटेड डेटा पैक

The exact sense of a/the is usually understood from context. That is normal Hindi grammar, not something missing from the sentence.

Yes. The verb would change according to the gender and number of the subject.

For example:

• यह पैक ... देता है।
  masculine singular

• ये पैक ... देते हैं।
  masculine plural

• यह योजना ... देती है।
  feminine singular

So if पैक were replaced by a feminine noun like योजना or सुविधा, the verb would become देती है.

That helps show that देता है is agreeing with पैक, not with डेटा or एसएमएस.
