حط رصيد زيادة بالتلفون حتى تقدر تتصل اذا صار شي.

حط is the imperative form meaning put or add.

In this sentence, it means add/top up credit on the phone. So حط رصيد is a very common colloquial way to say put credit on the phone or top up your balance.

It is addressed to one male.
If you were speaking to a woman, you would usually say حطي.

رصيد means balance, credit, or phone credit, depending on context.

Here it means prepaid phone credit. So:

• حط رصيد = add credit
• ما عندي رصيد = I don’t have any credit
• خلص الرصيد = the credit ran out

In everyday Levantine, this is a very common word when talking about prepaid mobile phones.

زيادة literally means extra, more, or additional.

So رصيد زيادة means extra credit or some more credit.

It adds the idea that you should not just have credit, but a bit more than usual, for safety.

بالتلفون literally means in the phone or on the phone, but in natural English we would usually say on your phone or for your phone.

In colloquial Arabic, using بـ in expressions like this is very normal.
So حط رصيد زيادة بالتلفون means something like:

• Put some extra credit on the phone
• Top up your phone with extra credit

You may also hear similar words like:

• بالموبايل = on the mobile
• بالتليفون = same word, different pronunciation/spelling choice

Here حتى means so that or in order that.

So:

• حتى تقدر تتصل = so that you can call

In Levantine, حتى is very commonly used to introduce purpose:

• خد معك مي حتى ما تعطش = Take water with you so you won’t get thirsty
• بكّر حتى تلحق = Leave early so you make it on time

So in this sentence, it connects the advice with the reason for it.

Because after حتى, Levantine normally uses the present tense to express purpose or ability.

• تقدر = you can / you are able
• تتصل = you call / you make a call

Together:

• حتى تقدر تتصل = so that you can call

Both verbs are addressed to you. The تـ at the beginning marks the second person here.

تقدر means be able to or can.

So:

• حتى تتصل = so that you call
• حتى تقدر تتصل = so that you can call

Using تقدر makes the meaning more natural here, because the point is that having extra credit gives you the ability to call if needed.

It is similar to English:

• Top up your phone so you call → not natural
• Top up your phone so you can call → natural

Literally, it means if a thing happened.

But in natural English, it means:

• if something happens
• in case something happens
• if anything happens

Here:

• اذا = if
• صار = happened / occurred / became
• شي = thing, but colloquially it often means something

So اذا صار شي is a very common everyday expression for if something happens.

This is a very common feature in spoken Arabic.

After اذا (if), Arabic often uses the past tense to talk about a possible future event. So although صار is grammatically past, the meaning here is:

• if something happens
• if anything should happen

This is normal and idiomatic.

Compare:

• اذا إجا، خبرني = If he comes, tell me
• literally: if he came, tell me

So the tense does not always match English tense directly.

شي literally means thing, but in colloquial Arabic it very often functions like something or anything, depending on context.

So:

• صار شي؟ = Did something happen?
• في شي؟ = Is there something wrong? / Is something up?
• اذا صار شي = if something happens

You do not need a separate word for some here. In colloquial usage, شي can carry that meaning by itself.

As written, it is addressed to one man or one boy.

That is because of forms like:

• حط
• تقدر
• تتصل

If you were addressing one woman, a common Levantine version would be:

• حطي رصيد زيادة بالتلفون حتى تقدري تتصلي اذا صار شي

If you were speaking to more than one person, the forms would change again.

This is Levantine colloquial Arabic, not full Modern Standard Arabic.

Clues include:

• حط as an everyday imperative
• شي for something
• the overall casual spoken structure

A more MSA-like version might be something like:

• ضَعْ رصيدًا إضافيًا في الهاتف حتى تستطيع الاتصال إذا حدث شيء

But that sounds much more formal and less like everyday speech.

The original sentence is natural for conversation.

A simple broad transliteration would be:

ḥuṭṭ raṣīd ziyāde b-it-tilifōn ḥatta tiʔdar titteṣel iza ṣār shi

A few notes:

• حط = ḥuṭṭ
• رصيد = raṣīd
• زيادة = ziyāde
• بالتلفون = often pronounced something like bit-tilifōn
• تقدر = tiʔdar or sometimes closer to taʔdar, depending on region
• تتصل = titteṣel
• اذا = iza
• صار = ṣār
• شي = shi

Pronunciation varies a bit across Levantine regions, but this will be understood broadly.

A very natural translation would be:

• Top up your phone with some extra credit so you can call if anything happens.

Other natural versions are:

• Put some extra credit on your phone in case something happens.
• Add extra credit to your phone so you can make a call if needed.

The exact wording in English can vary, but the core idea is:
make sure you have enough phone credit for an emergency.
