هو بيمسح البيانات من التليفون.

You can absolutely drop هو.

• بيمسح البيانات من التليفون already means he is deleting/erasing the data from the phone.
• Adding هو can make the subject clearer, more contrastive, or a little more conversational: he is deleting it.

So:

• بيمسح البيانات من التليفون = He’s deleting the data from the phone
• هو بيمسح البيانات من التليفون = He’s deleting the data from the phone / He is the one deleting it

In Egyptian Arabic, subject pronouns are often optional because the verb already tells you the person.

In Egyptian Arabic, بيـ is a marker for the present/imperfect.

So بيمسح can mean:

• he deletes
• he is deleting
• he erases
• he is erasing

It often covers both habitual and ongoing present meaning, depending on context.

Compare:

• مسح = he erased / deleted (past)
• بيمسح = he erases / is erasing (present)

It can mean either one.

Egyptian Arabic often uses the same present form for:

• a current action: He is deleting the data
• a habitual action: He deletes data

Context tells you which meaning is intended.

For example:

• دلوقتي هو بيمسح البيانات من التليفون = Right now he’s deleting the data from the phone
• كل مرة بيمسح البيانات من التليفون = Every time he deletes the data from the phone

Because the basic meaning of مسح is to wipe or to erase, and that naturally extends to delete in digital contexts.

So بيمسح البيانات can mean:

• he wipes the data
• he erases the data
• he deletes the data

In everyday Egyptian Arabic, this is very normal for phones, files, messages, photos, and so on.

A more formal word for delete is يحذف, but يمسح is very common in speech.

Yes.

That verb is used both literally and digitally.

Examples:

• بيمسح الترابيزة = He’s wiping the table
• بيمسح الصورة = He’s deleting the picture
• بيمسح البيانات = He’s deleting/erasing the data

So the exact meaning depends on the object and context.

A rough pronunciation is:

huwwa byimsaḥ el-bayānāt men et-telefōn

A few notes:

• هو sounds like huwwa
• بيمسح sounds like byimsaḥ
• البيانات is roughly el-bayānāt
• من is often pronounced men
• التليفون is roughly et-telefōn

The last sound in بيمسح is ḥ, a stronger breathy h sound from the throat.

Formally, بيانات is a plural form. In meaning, though, it often works like data / information / details, especially in technical or formal language.

So in this sentence, البيانات is best understood as:

• the data
• sometimes the information

Even though it is morphologically plural, you do not need to translate it as the pieces of data every time.

Yes, but it sounds a bit formal or technical.

In real speech, Egyptians might also say:

• الداتا = the data (very common in tech contexts)
• المعلومات = the information

So your sentence is correct, but البيانات feels a little more formal than very casual daily speech.

Because من means from, and with verbs like erase/delete/remove, Arabic often uses من to show where something is being removed from.

So:

• بيمسح البيانات من التليفون = He’s deleting the data from the phone

That is very natural.

Not with the same meaning.

• من التليفون = from the phone → removal
• في التليفون = in/on the phone → location

So:

• بيمسح البيانات من التليفون = He’s deleting the data from the phone
• البيانات في التليفون = The data is on the phone

You could also say something like:

• بيمسح البيانات اللي في التليفون = He’s deleting the data that’s on the phone

But plain في التليفون does not replace من التليفون here.

Yes. Both are possible, but الموبايل is very common for a mobile phone.

So these are both natural:

• هو بيمسح البيانات من التليفون
• هو بيمسح البيانات من الموبايل

If you specifically mean a cellphone, الموبايل may sound more everyday and more specific.

Because Egyptian Arabic very often likes subject + verb + object, especially in normal conversation.

So this is very natural:

• هو بيمسح البيانات من التليفون

You can also simply say:

• بيمسح البيانات من التليفون

Compared with MSA, Egyptian is generally more comfortable with subject-first order in everyday speech.

They are not pronounced the same way.

• البيانات begins with ب, which is a moon letter, so the l of الـ stays:
  • el-bayānāt
• التليفون begins with ت, which is a sun letter, so the l assimilates:
  • et-telefōn, not el-telefōn

So in speech you hear:

• el-bayānāt
• et-telefōn

This is a very common feature of Arabic pronunciation.

Two common ways are:

• هو مش بيمسح البيانات من التليفون
• هو ما بيمسحش البيانات من التليفون

Both mean He isn’t deleting the data from the phone.

A quick note:

• مش
  • present verb is very common
• ما...ش is also very common colloquial negation

So both are useful patterns to learn.

Past:

• هو مسح البيانات من التليفون = He deleted the data from the phone

Future:

• هو هيمسح البيانات من التليفون = He will delete the data from the phone

So the timeline looks like this:

• مسح = past
• بيمسح = present
• هيمسح = future

No. In Egyptian Arabic, you do not use the case endings you may know from MSA.

So you just say:

• هو بيمسح البيانات من التليفون

No final -u, -a, or -i endings are needed in normal Egyptian speech. This is one reason spoken Egyptian feels simpler than fully vocalized MSA.
