Ten telefon jest zablokowany, bo trzy razy wpisałam nie to hasło.

Ten means this. So ten telefon = this phone.

Polish often uses demonstratives like ten / ta / to a bit more explicitly than English uses this in some contexts, especially when pointing out a specific thing. You could say just Telefon jest zablokowany if the phone is already clear from context, but Ten telefon makes it more specific.

Also, telefon is a masculine noun, so the correct form is ten.

Because telefon is a masculine singular noun in the nominative case.

The demonstrative this changes by gender in Polish:

• ten for masculine nouns
• ta for feminine nouns
• to for neuter nouns

Examples:

• ten telefon = this phone
• ta książka = this book
• to hasło = this password

So telefon takes ten.

Jest zablokowany means is blocked / is locked and describes the resulting state of the phone.

• zablokowany is a past passive participle/adjectival form from zablokować.
• jest zablokowany literally means is blocked.

This is natural when you want to say the phone is now in a locked state because of something that happened.

By contrast:

• blokuje się usually means is getting blocked / jams / freezes / locks itself, depending on context.
• That would suggest more of an ongoing process or repeated behavior, not the resulting state after entering the wrong password.

Bo means because.

It is very common in everyday spoken and written Polish.
Ponieważ also means because, but it sounds a bit more formal or more neutral in style.

So:

• Ten telefon jest zablokowany, bo... = natural, everyday
• Ten telefon jest zablokowany, ponieważ... = also correct, slightly more formal

Trzy razy means three times.

The noun is raz (time, as in one occurrence). After numbers like trzy, Polish uses the form razy in this expression:

• raz = once / one time
• dwa razy = twice / two times
• trzy razy = three times
• cztery razy = four times

This is a fixed and very common pattern, so it is best learned as a chunk:

• X razy = X times

Because the speaker is female.

In the past tense, Polish verbs agree with the gender of the speaker:

• wpisałam = I entered / typed (said by a woman)
• wpisałem = I entered / typed (said by a man)

So this sentence tells you that the person speaking is female.

Wpisałam comes from wpisać, which means to enter, to type in, or to fill in, depending on context.

Here it means:

• I typed in
• I entered

Since the sentence is about a phone and a password, wpisałam hasło means I entered/typed the password.

Nie to hasło literally means not that/the right password or the wrong password, but with a slightly different nuance from złe hasło.

• złe hasło = a bad/wrong password
• nie to hasło = not the correct one / not the one I was supposed to enter

In this sentence, nie to hasło suggests:

• there was a specific correct password,
• but the speaker entered a different one.

It is very natural in Polish when you mean I entered the wrong one, rather than saying the password itself was somehow inherently bad.

Because hasło is the direct object of wpisałam, and here it is in the accusative singular.

For neuter inanimate nouns like hasło, the accusative singular is the same as the nominative singular:

• nominative: to hasło
• accusative: wpisałam hasło

So although it is the object, the form stays hasło.

• telefon is in the nominative because it is the subject of jest zablokowany
• hasło is in the accusative because it is the direct object of wpisałam

Breakdown:

• Ten telefon = subject → nominative
• jest zablokowany = predicate
• wpisałam nie to hasło = verb + direct object
• hasło = accusative, though it looks the same as nominative because it is neuter singular

Yes, Polish word order is more flexible than English.

The given order is natural:

• trzy razy wpisałam nie to hasło = I entered the wrong password three times

But you could also hear:

• Wpisałam trzy razy nie to hasło
• Nie to hasło wpisałam trzy razy

The meaning stays broadly the same, but the emphasis changes:

• trzy razy first emphasizes the number of attempts
• nie to hasło earlier can emphasize that it was the wrong one
• wpisałam earlier is a more neutral verb-centered order

So the original sentence sounds natural and puts good focus on three times.

Wpisać is perfective. Here that makes sense because the speaker is talking about completed actions: she entered the password three times, and that caused the phone to become blocked.

In Polish:

• wpisywać = imperfective, repeated/ongoing process
• wpisać = perfective, completed act

Since the phone became locked after those completed entries, perfective wpisałam fits well.

That said, in some contexts Polish can use an imperfective verb with repeated actions, but here trzy razy wpisałam sounds very natural because the focus is on three completed attempts.

Usually a temporary resulting state.

Zablokowany means something like:

• blocked
• locked
• disabled

With a phone, it normally means the phone is currently locked because of the failed password attempts. It does not suggest permanent destruction; just that access is blocked for now.

Yes, but it means something slightly different.

• Ten telefon jest zablokowany = This phone is blocked/locked
  Focus: the current state

• Ten telefon został zablokowany = This phone got blocked / was blocked
  Focus: the event of becoming blocked

In your sentence, jest zablokowany works very well because the important point is the phone’s present state and the reason for it.

Yes, it is natural and idiomatic.

It sounds like normal everyday Polish:

• Ten telefon jest zablokowany = the problem
• bo trzy razy wpisałam nie to hasło = the explanation

A native speaker would understand it immediately as: The phone is locked because I entered the wrong password three times.
