यह मोबाइल प्लान है।

A simple breakdown is:

• यह = this
• मोबाइल = mobile
• प्लान = plan
• है = is

So the structure is literally:

this mobile plan is

In natural English, that becomes This is a mobile plan or This is a mobile plan/package, depending on context.

Hindi normally places the verb at the end of the sentence. That is one of the biggest word-order differences from English.

So instead of English:

• This is a mobile plan

Hindi prefers:

• This mobile plan is
• यह मोबाइल प्लान है।

This is completely normal in Hindi.

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

So:

• यह मोबाइल प्लान है।

can mean:

• This is a mobile plan
• sometimes even This is the mobile plan, depending on context

Hindi often leaves article-like meaning to context rather than adding a separate word.

यह means this.

In careful or traditional transliteration, it is written yah, but in everyday pronunciation it is often closer to yeh.

So learners often hear:

• यह pronounced like yeh

That is normal.

है is the present-tense form of to be for a singular subject in this kind of sentence. In this sentence, it works like English is.

So:

• यह ... है = This ... is

If the subject were plural, Hindi would normally use हैं instead:

• ये मोबाइल प्लान हैं। = These are mobile plans.

They are loanwords, mainly from English, but they are very common in modern Hindi.

Hindi speakers often use English-origin words, especially for technology, business, and services. So sentences like this are very natural in everyday modern Hindi.

You will see a lot of Hindi that mixes native vocabulary with borrowed English words written in Devanagari.

Not much here.

Hindi nouns have grammatical gender, but in this sentence there is no adjective changing form to show it, and है does not change for masculine vs. feminine singular.

So whether प्लान is treated as masculine in usage does not really affect this sentence’s form.

You would notice gender more clearly in sentences with adjectives or past-tense verbs, for example.

Yes, in everyday spoken Hindi, many speakers use ये for singular this in casual speech.

But in standard written Hindi:

• यह = this
• ये = these

So for a learner, it is best to understand:

• यह मोबाइल प्लान है। = standard written form
• ये मोबाइल प्लान hai may be heard in conversation

Yes, it is natural, especially in contexts like advertising, customer service, or talking about phone packages.

Depending on context, a speaker might also say:

• यह मोबाइल का प्लान है। = This is a mobile plan / phone plan
• यह मोबाइल प्लान है = This is a mobile plan

The original sentence is short, clear, and completely normal.

A question:

• क्या यह मोबाइल प्लान है?
• Is this a mobile plan?

A negative:

• यह मोबाइल प्लान नहीं है।
• This is not a mobile plan.

In Hindi, नहीं is placed before है in simple negative sentences like this.
