eSIM працює.

Працює means works, is working, or functions.

So eSIM працює means that the eSIM is functioning properly. In English, depending on context, you might translate it as:

• The eSIM works.
• The eSIM is working.
• eSIM works.

Ukrainian does not use articles like the or a/an.

So where English says:

• The eSIM works
• An eSIM works

Ukrainian simply says:

• eSIM працює

The exact English article is understood from context.

Technical terms, brand-like names, and abbreviations are often kept in their original Latin spelling in Ukrainian, especially in modern usage.

So eSIM працює is completely natural.

You may also sometimes see transliterated or adapted forms in informal contexts, but keeping eSIM as eSIM is standard and very common.

Працює is pronounced approximately like prats-YOO-ye.

A rough breakdown:

• пра = pra
• цю = tsyu
• є = ye

The stress is on the ю syllable:

• пра-цю́-є

So the full word is approximately prats-YOO-ye.

Because працює is the 3rd person singular present tense form of the verb працювати (to work).

Here is the pattern:

• я працюю = I work / am working
• ти працюєш = you work
• він / вона / воно працює = he / she / it works
• вони працюють = they work

Since eSIM is treated as a single thing, Ukrainian uses the 3rd person singular form:

• eSIM працює

In a sentence like this, learners usually do not need to worry much about gender, because the verb form працює is the same for he/she/it works.

With borrowed technical terms like eSIM, gender can be less obvious than with ordinary nouns. In actual use, speakers often treat such tech terms based on the implied noun or just use them naturally without focusing on gender in very short sentences.

For this sentence, the important point is simply:

• eSIM is singular
• therefore the verb is працює

Yes, you could, but it changes the emphasis.

• eSIM працює = neutral, standard word order
• Працює eSIM = more marked; it can sound like The eSIM works or It’s the eSIM that works, depending on context

Ukrainian word order is more flexible than English word order, but the neutral default here is:

• eSIM працює

You add не before the verb:

• eSIM не працює = The eSIM doesn’t work / The eSIM is not working

This is the normal way to negate verbs in Ukrainian.

Very often, Ukrainian makes a yes/no question just by intonation:

• eSIM працює? = Does the eSIM work? / Is the eSIM working?

In speech, your voice rises like it does in English. In writing, the question mark shows that it is a question.

It is used for both.

Працювати can mean:

• to work as a person does
• to function / operate for machines, devices, apps, systems, internet, and so on

So with eSIM, працює means functions / is working properly, not that the eSIM is doing a job.

Yes. eSIM працює is short, natural, and very realistic, especially in tech support, phone settings, online chats, or troubleshooting.

For example, someone might say:

• eSIM працює.
• Інтернет працює.
• Карта не працює.

This kind of short subject + verb sentence is very common in Ukrainian.
