मोबाइल प्लान में न केवल डेटा, बल्कि टॉक टाइम भी है।

It is the Hindi pattern for not only ... but also ....

So in this sentence:

न केवल डेटा, बल्कि टॉक टाइम भी

means:

not only data, but also talk time

A very common structure is:

न केवल X, बल्कि Y भी

or

केवल X ही नहीं, बल्कि Y भी

Both express the same basic idea.

Because न केवल is a fixed expression. In this pattern, Hindi normally uses न केवल rather than नहीं केवल.

So you should learn न केवल ... बल्कि ... भी as a set phrase.

Compare:

• न केवल = not only
• बल्कि = but rather / but
• भी = also / too

In regular everyday negation, नहीं is much more common, but in set expressions like this, न is standard.

में means in. Here it shows what is included in the mobile plan.

So:

• मोबाइल प्लान = mobile plan
• मोबाइल प्लान में = in the mobile plan

Hindi often uses X में Y है to mean X has Y or there is Y in X.

So the sentence is literally structured more like:

In the mobile plan, there is not only data, but also talk time.

भी means also / too, and in Hindi it usually comes right after the word or phrase it emphasizes.

So:

• टॉक टाइम भी = talk time too / talk time also

In this sentence, भी highlights that talk time is an additional feature, not the only one.

This is very normal Hindi word order.

Because Hindi often leaves out repeated words when they are easy to understand from context.

The full version could be:

मोबाइल प्लान में न केवल डेटा है, बल्कि टॉक टाइम भी है।

Here, the first है is omitted because the sentence is smoother without repeating it.

This kind of omission is very common, especially in formal writing, advertising language, and neat parallel structures.

A good way to understand this sentence is to mentally expand it as:

मोबाइल प्लान में न केवल डेटा है, बल्कि टॉक टाइम भी है।

Now each part has its own singular है:

• डेटा है
• टॉक टाइम भी है

So the final है matches टॉक टाइम, and the first है is simply omitted.

Also, डेटा and टॉक टाइम are being treated as individual included items, not as a single plural subject like data and talk time are.

If you rewrote the sentence differently, you could get a plural verb, for example:

मोबाइल प्लान में डेटा और टॉक टाइम दोनों हैं।

That version uses हैं because दोनों makes the pair clearly plural.

Not exactly. In this pattern, बल्कि works like but rather / but also / but in fact depending on context.

In न केवल ... बल्कि ... भी, it is the standard connector for the second part of the comparison.

So although English usually says not only X but also Y, Hindi prefers:

न केवल X, बल्कि Y भी

You should think of बल्कि here as the natural word that completes the pattern, rather than trying to match it to one single English word every time.

They are English loanwords used in Hindi, written in Devanagari script:

• मोबाइल प्लान = mobile plan
• डेटा = data
• टॉक टाइम = talk time

Modern Hindi, especially in technology, business, and advertising, uses many English-origin words. This is completely normal.

A learner should get used to seeing English words written in Hindi script. Native speakers use them very naturally.

It sounds very natural in an advertising, product-description, or informational context.

Because of the structure न केवल ... बल्कि ... भी, it feels a little more polished than everyday casual speech.

In very casual spoken Hindi, someone might say:

इस प्लान में सिर्फ डेटा ही नहीं, टॉक टाइम भी है।

That means the same thing, but sounds more conversational.

So the original sentence is correct and natural, but it has a slightly more polished or promotional tone.

Yes. Some common alternatives are:

• मोबाइल प्लान में केवल डेटा ही नहीं, बल्कि टॉक टाइम भी है।
• मोबाइल प्लान में सिर्फ डेटा ही नहीं, टॉक टाइम भी है।
• मोबाइल प्लान में डेटा के साथ टॉक टाइम भी है।
• मोबाइल प्लान में डेटा और टॉक टाइम दोनों हैं।

These are all natural, though the nuance changes slightly:

• न केवल ... बल्कि ... भी = more formal/polished
• सिर्फ ... ही नहीं = more conversational
• दोनों हैं = straightforward and simple

Yes, somewhat. Hindi word order is more flexible than English, especially with emphasis.

For example, you could also say:

मोबाइल प्लान में न केवल डेटा है, बल्कि टॉक टाइम भी है।

This version is a little more explicit because both clauses have verbs.

You might also hear:

इस मोबाइल प्लान में न केवल डेटा, बल्कि टॉक टाइम भी है।

Adding इस makes it in this mobile plan.

The exact order can shift for style or emphasis, but the basic pattern न केवल X, बल्कि Y भी should stay intact.

Literally, yes, में means in. But in natural English-style meaning, it is better understood as included in the mobile plan or part of the mobile plan.

Hindi often uses में where English might use:

• in
• with
• as part of
• included in

So here, don’t picture physical location. Think of contents or features included in a plan.

The main thing is to remember the full pairing:

न केवल X, बल्कि Y भी

Common learner mistakes are:

• forgetting भी
• replacing बल्कि with a plain लेकिन
• using awkward English-like word order

A good model sentence is:

इस कोर्स में न केवल किताबें, बल्कि वीडियो भी हैं।

= This course has not only books, but also videos.

So if you remember the pattern as one chunk, it becomes much easier to use correctly.
