Simkadi yangu haina salio sasa.

Simkadi means SIM card. It is a loanword adapted into Swahili spelling. In everyday writing, many people write it as one word: simkadi.

You may also see:

• SIM kadi
• kadi ya simu

All of these can refer to a SIM card, but simkadi is common and easy to understand.

No. In this sentence, simkadi is just the noun SIM card. The beginning si- is not the negative marker here.

So:

• simkadi = a noun
• haina = the part that carries the negative meaning: does not have

In Swahili, possessives usually come after the noun, not before it.

So:

• simkadi yangu = my SIM card
• literally: SIM card my

This is a very normal Swahili pattern:

• simu yangu = my phone
• nyumba yangu = my house

Yangu means my, but its exact form depends on the noun class of the noun it describes.

Simkadi behaves like a class 9 singular noun, and class 9 singular nouns use the possessive form yangu.

That is why you say:

• simkadi yangu = my SIM card

Not:

• simkadi wangu
• simkadi changu

Those would be the wrong agreement for this noun.

Because the subject is simkadi yangu = my SIM card, which is treated as it in English.

Swahili verbs must agree with the noun class of the subject. Since simkadi is class 9 singular, the verb uses class 9 agreement.

Compare:

• ina = it has
• haina = it does not have

So:

• Simkadi yangu ina salio = My SIM card has balance
• Simkadi yangu haina salio = My SIM card does not have balance

Haina can be broken down like this:

• ha- = negative marker
• i- = subject marker for class 9 singular
• -na = have / be with

So haina literally means it does not have.

This is a very useful pattern:

• nina = I have
• sina = I do not have
• una = you have
• huna = you do not have
• ina = it has
• haina = it does not have

Salio means balance, remaining credit, or remaining amount.

In this sentence, it most naturally means the remaining balance on the SIM card, such as:

• airtime credit
• phone balance
• sometimes, depending on context, available data or account balance

It is more specific than just money.

For example:

• pesa = money
• salio = balance / remaining credit

Sasa means now or at the moment.

Putting it at the end is very natural in Swahili:

• Simkadi yangu haina salio sasa.

It tells you the time situation: right now.

You can also move it for emphasis, for example:

• Sasa simkadi yangu haina salio.

But the original word order sounds normal and clear.

Yes. Sina salio sasa means I have no balance now, and it is a very natural everyday way to say this if the context is already clear.

The difference is:

• Simkadi yangu haina salio sasa = explicitly talks about my SIM card
• Sina salio sasa = shorter, more conversational, focused on I

So the original sentence is a bit more explicit, while Sina salio sasa is often what people would say in conversation.

You would change the agreement:

• Simkadi zangu hazina salio sasa.

Changes:

• yangu → zangu
• haina → hazina

The noun simkadi often stays the same in form, but the possessive and verb show that it is plural.

So:

• simkadi yangu haina = my SIM card does not have
• simkadi zangu hazina = my SIM cards do not have
