मोबाइल नेटवर्क आज कमज़ोर है।

Literally, it is:

• मोबाइल नेटवर्क = mobile network / phone signal
• आज = today
• कमज़ोर = weak
• है = is

So the literal order is mobile network today weak is.

That sounds unusual in English, but it is normal in Hindi.

Hindi usually puts the main verb or copula near the end of the sentence. So where English says:

• The mobile network is weak today

Hindi says:

• मोबाइल नेटवर्क आज कमज़ोर है

A good beginner pattern is:

subject + time/place/etc. + description + है/हैं

So कमज़ोर है = is weak.

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

So मोबाइल नेटवर्क आज कमज़ोर है can naturally mean:

• The mobile network is weak today
• Mobile network is weak today

Context tells you which meaning is intended.

Yes, आज can move. Hindi word order is more flexible than English, especially with adverbs like today.

These are all possible:

• मोबाइल नेटवर्क आज कमज़ोर है
• आज मोबाइल नेटवर्क कमज़ोर है

Both are natural. The version with मोबाइल नेटवर्क first puts the topic first: as for the mobile network, today it is weak.

Yes. This is very normal modern Hindi.

Hindi often uses borrowed English words, especially for technology and daily life, and writes them in Devanagari:

• मोबाइल = mobile
• नेटवर्क = network

So this is perfectly ordinary colloquial Hindi. You will hear many such mixed-origin expressions in real speech.

कमज़ोर is pronounced approximately kam-zor.

The letter ज़ is ज with a nukta (the dot below), and it gives a z sound.

So:

• ज = j
• ज़ = z

That is why कमज़ोर sounds like kam-zor, not kam-jor.

Usually, no. कमज़ोर is an adjective that normally stays the same.

So you can have:

• masculine singular: लड़का कमज़ोर है
• feminine singular: लड़की कमज़ोर है
• plural: लड़के कमज़ोर हैं
• plural feminine: लड़कियाँ कमज़ोर हैं

What changes is usually है / हैं, not कमज़ोर.

Most speakers treat नेटवर्क as masculine, especially because many borrowed technical nouns default to masculine in everyday Hindi.

However, in this sentence you cannot really see that clearly, because:

• कमज़ोर does not change
• है only shows singular

So for this sentence, the gender is not very important for understanding or forming it.

Usually it means the mobile signal / cellular network is weak.

So if your phone has poor bars or poor reception, this sentence fits well.

If you specifically mean internet speed, Hindi might use something like:

• मोबाइल इंटरनेट आज धीमा है = The mobile internet is slow today.

But in everyday speech, people sometimes still use नेटवर्क loosely for signal problems in general.

Yes, absolutely.

There is a small nuance:

• मोबाइल नेटवर्क आज कमज़ोर है = the mobile network is weak today
• मोबाइल का नेटवर्क आज कमज़ोर है = the phone’s network/signal is weak today

The second version can sound a bit more like you are talking about the signal on a particular phone. Both are understandable.

Use है for singular and हैं for plural (and also for respectful singular in some contexts).

Here, नेटवर्क is singular, so:

• मोबाइल नेटवर्क आज कमज़ोर है

If the subject were plural, you would use हैं:

• सभी नेटवर्क आज कमज़ोर हैं = All the networks are weak today.

That mark is the Hindi full stop, called दंड or पूर्ण विराम.

So:

• । in Hindi works like . in English

In modern texting and informal typing, many people also use a regular period ., but । is the traditional standard punctuation mark.
