क्या यह मोबाइल प्लान प्रीपेड है?

At the beginning of a sentence, क्या usually marks a yes/no question.

So:

• क्या यह मोबाइल प्लान प्रीपेड है? = Is this mobile plan prepaid?

In this use, क्या does not mean what.
It simply signals that the speaker is asking for confirmation.

Compare:

• क्या यह सही है? = Is this correct?
• क्या तुम तैयार हो? = Are you ready?

But in other positions, क्या can mean what:

• यह क्या है? = What is this?

So position matters.

Hindi often uses a structure closer to:

• Is this mobile plan prepaid?
• literally: This mobile plan prepaid is?

That is normal in Hindi.

Breakdown:

• क्या = question marker
• यह = this
• मोबाइल प्लान = mobile plan
• प्रीपेड = prepaid
• है = is

Hindi commonly places the main descriptive word or predicate before है.

So:

• यह मोबाइल प्लान प्रीपेड है। = This mobile plan is prepaid.
• Add क्या at the front → क्या यह मोबाइल प्लान प्रीपेड है? = Is this mobile plan prepaid?

Because Hindi usually puts the verb at the end of the clause. This is one of the most basic word-order patterns in Hindi.

So while English says:

• This plan is prepaid

Hindi says:

• यह प्लान प्रीपेड है

The verb है means is/am/are depending on context, but here it means is.

यह means this.

In this sentence, it points to a specific mobile plan near the speaker, or one currently being discussed:

• क्या यह मोबाइल प्लान प्रीपेड है? = Is this mobile plan prepaid?

If you wanted to say that mobile plan, you would usually use वह instead:

• क्या वह मोबाइल प्लान प्रीपेड है? = Is that mobile plan prepaid?

A useful thing to know: in everyday speech, यह is often pronounced more like येह.

Modern Hindi very commonly uses English loanwords, especially for technology, business, phones, banking, and customer service.

So phrases like these are completely natural:

• मोबाइल प्लान
• प्रीपेड
• पोस्टपेड
• डेटा
• नेटवर्क

You may sometimes see more Sanskrit-based or formal alternatives, but in everyday conversation and advertising, English-based vocabulary is extremely common.

So मोबाइल प्लान प्रीपेड sounds normal and natural.

Yes. In this sentence, प्रीपेड is describing the plan, so it works like an adjective or predicate complement:

• यह मोबाइल प्लान प्रीपेड है। = This mobile plan is prepaid.

Hindi often uses borrowed English words this way without changing their form.

So you can also compare:

• यह नंबर एक्टिव है। = This number is active.
• यह ऑफर वैलिड है। = This offer is valid.

Loanwords like प्रीपेड, एक्टिव, and वैलिड often stay unchanged.

Yes, and it is grammatical, but the emphasis is slightly different.

• क्या यह मोबाइल प्लान प्रीपेड है?
  = Is this mobile plan prepaid?
  Focus: you already know it is a mobile plan, and you are asking whether its type is prepaid.

• क्या यह प्रीपेड मोबाइल प्लान है?
  = Is this a prepaid mobile plan?
  Focus: prepaid is part of the noun phrase itself.

Both are possible. The original sentence is very natural when asking about the status/type of a specific plan.

Because मोबाइल प्लान is singular here.

• यह मोबाइल प्लान ... है = This mobile plan ... is

If the subject were plural, you would normally use हैं:

• क्या ये मोबाइल प्लान प्रीपेड हैं? = Are these mobile plans prepaid?

So:

• singular → है
• plural / respectful contexts → हैं

Yes, in conversation you often can, if your intonation clearly makes it a question.

So a speaker might say:

• यह मोबाइल प्लान प्रीपेड है?

This can still mean:

• Is this mobile plan prepaid?

However, adding क्या makes the question structure clearer, especially for learners and in more careful speech:

• क्या यह मोबाइल प्लान प्रीपेड है?

So both can work, but the version with क्या is safer and more standard for beginners.

Simple answers could be:

• हाँ, यह प्रीपेड है। = Yes, it is prepaid.
• नहीं, यह प्रीपेड नहीं है। = No, it is not prepaid.
• नहीं, यह पोस्टपेड है। = No, it is postpaid.

Hindi often repeats part of the sentence in the answer, just like English does.

In practice, borrowed nouns like प्लान are commonly treated as masculine, but in this sentence it does not create any visible change, because:

• प्रीपेड does not change form here
• है is the same regardless of gender in the singular present tense

So even if you are not sure about gender yet, you can still use this sentence correctly:

• क्या यह मोबाइल प्लान प्रीपेड है?

Gender becomes more noticeable in other structures, especially with adjectives that change form and with past-tense constructions.

A simple learner-friendly pronunciation is:

• kyaa yeh mobile plaan prepaid hai?

A few notes:

• क्या sounds like kyaa
• यह is often pronounced yeh
• प्लान sounds close to English plan, but with Hindi phonetics
• है sounds like hai

A more natural rhythm would be something like:

• kyaa yeh mobile plaan prepaid hai?

Yes, people really would say this, especially in shops, customer-service settings, telecom discussions, or when comparing SIM/phone plans.

It sounds natural and practical.

For example:

• at a mobile store
• when reading plan details online
• while asking customer support
• when checking whether recharge is needed in advance

So this is not an artificial textbook sentence. It fits real-life usage well.
