مندوب التوصيل هيتصل بيا النهارده.

A natural Egyptian pronunciation is:

manduub et-tawSiiL hayittaSil biyya en-naharda

A few notes:

• مندوب = manduub
• التوصيل is usually pronounced et-tawSiiL in Egyptian, not al-tawSīl
• هيتصل = hayittaSil or hayitSil depending on speed and accent
• بيا = biyya
• النهارده = en-naharda

You may also hear slightly different spellings in transliteration, because Egyptian Arabic is not standardized in Latin letters.

Here is the breakdown:

• مندوب = representative / agent / courier
• التوصيل = delivery
• مندوب التوصيل = the delivery person / delivery representative / courier
• هيتصل = will call / will contact
• بيا = me
• النهارده = today

So grammatically, it is:

• subject: مندوب التوصيل
• verb: هيتصل
• prepositional object: بيا
• time expression: النهارده

In Egyptian Arabic:

• بيتصل usually means he calls / he is calling / he calls regularly
• هيتصل means he will call

The هـ at the beginning is a very common future marker in Egyptian Arabic.

So:

• بيتصل بيا = he calls me / he is calling me
• هيتصل بيا = he will call me

Egyptian Arabic commonly marks the future with هـ or حـ before the present verb.

So these are both possible in speech:

• هيتصل بيا
• حيتصل بيا

Both mean he will call me.

The exact choice can depend on speaker habit, region, and writing style. In informal Egyptian writing, both are common.

Because the verb اتصل in Arabic normally takes بـ for the person being contacted.

So Arabic says, literally:

• he contacted/called with me
• but in natural English: he called me

Examples:

• اتصل بيا = he called me
• اتصل بيك = he called you
• اتصل بيها = he called her

Using لي would not be the normal way to express call someone with this verb.

بيا is the preposition بـ plus the pronoun ـي.

• بـ = with / by / to, depending on the verb
• ـي = me

Together:

• بـ + ي → بيا
• pronounced biyya

This is very common with اتصل:

• بيا = me
• بيك = you (masculine)
• بيكي = you (feminine)
• بيه = him
• بيها = her
• بينا = us
• بيهم = them

The base verb is اتصل.

In Egyptian Arabic:

• اتصل = to call / to contact
• بيتصل = he calls / he is calling
• هيتصل = he will call

This verb is very common for phone calls and contacting someone.

Examples:

• أنا هاتصل بيك = I’ll call you
• هي اتصلت بيا = she called me

Yes, it is a very natural expression.

• مندوب literally means something like representative, agent, or courier
• التوصيل means delivery

So مندوب التوصيل is a common way to say the delivery guy / delivery courier / delivery person.

You may also hear other everyday expressions, such as:

• بتاع الدليفري = the delivery guy
• عامل التوصيل = delivery worker

But مندوب التوصيل sounds perfectly normal and clear.

Because in Egyptian Arabic, the definite article ال is usually pronounced el- or et-, depending on the next sound.

Since ت is a sun letter, the l sound of ال assimilates to it.

So:

• التوصيل
• pronounced et-tawSiiL

The same thing happens in:

• النهارده → en-naharda

Because ن is also a sun letter.

النهارده means today, and yes, it is a very common Egyptian Arabic word.

It corresponds to MSA اليوم.

In Egyptian speech:

• النهارده = today
• بكره = tomorrow
• امبارح = yesterday

So this sentence sounds clearly Egyptian because of words like النهارده and the future form هيتصل.

Yes, word order in Egyptian Arabic is flexible.

This sentence is completely natural:

• مندوب التوصيل هيتصل بيا النهارده

But you could also say:

• هيتصل بيا مندوب التوصيل النهارده
• النهارده مندوب التوصيل هيتصل بيا

The most neutral version is usually the original one, where the subject comes first.

Yes. That is also natural Egyptian Arabic.

Both of these are used:

• هيتصل بيا
• حيتصل بيا

Both mean will call me.

Some speakers prefer one more than the other, but both are widely understood and common.

Yes, مندوب is masculine.

The feminine form is:

• مندوبة

So you could say:

• مندوبة التوصيل هتتصل بيا النهارده
  = the delivery woman will call me today

Notice that the verb also changes:

• هيتصل = he will call
• هتتصل = she will call

With اتصل بـ, you attach the pronoun after بـ.

Common forms:

• بيا = me
• بيك = you (to a man)
• بيكي = you (to a woman)
• بيه = him
• بيها = her
• بينا = us
• بيكم = you all
• بيهم = them

Examples:

• هيتصل بيك النهارده = he’ll call you today
• هيتصل بينا النهارده = he’ll call us today

It is clearly Egyptian colloquial Arabic, not Modern Standard Arabic.

Signs of that include:

• هيتصل for the future
• بيا in this colloquial style
• النهارده for today

A more formal MSA-style version would look different, for example:

• سيتصل بي مندوب التوصيل اليوم

But that would sound formal/bookish, not like everyday Egyptian speech.

Yes, اتصل is very normal and common for phone calls.

In everyday speech, people may also use English-based expressions in some contexts, but اتصل بيا is a standard, natural Egyptian way to say call me.

For example:

• اتصل بيا لما توصل = call me when you arrive

So the sentence sounds natural and native.
