Depende sa badyet ang roaming.

Both are possible.

Depende sa badyet ang roaming is a very natural Filipino word order. It puts the description first, then the topic:

• Depende sa badyet = depends on the budget
• ang roaming = the roaming / roaming service

This pattern is common in Filipino:

• Mahal ang pagkain. = The food is expensive.
• Malayo ang palengke. = The market is far.

You can also say:

• Ang roaming ay depende sa badyet.

That version sounds a little more formal or more explicitly structured, but it means the same thing.

Here, sa means on, to, in, at, or for, depending on context. In this sentence, it helps express depends on:

• depende sa badyet = depends on the budget

So sa badyet is the thing being referred to as the basis of the dependence.

A very common pattern is:

• depende sa + noun

Examples:

• Depende sa oras. = It depends on the time.
• Depende sa lugar. = It depends on the place.
• Depende sa panahon. = It depends on the weather/season.

Ang marks the topic or focus of the sentence. In this sentence, ang roaming is the thing being talked about.

So the structure is roughly:

• Depende sa badyet = comment/predicate
• ang roaming = topic

You can think of it like:

• As for roaming, it depends on the budget.

That is why ang appears before roaming.

Not usually in the same way English depend is a verb.

In Filipino, depende is commonly used more like a predicate word in expressions such as:

• Depende sa...
• Depende iyon sa...

It behaves somewhat like an adjective or descriptive predicate in many sentences.

You may also see:

• nakadepende sa... = dependent on / depending on

Examples:

• Depende sa sitwasyon.
• Nakadepende sa sitwasyon ang desisyon.

So for learners, the easiest thing is to remember depende sa... as a fixed and very common pattern meaning depends on...

Badyet is the Filipino spelling of the English word budget.

Filipino often adapts borrowed English words to match Filipino spelling and pronunciation:

• budget → badyet
• project → proyekto
• check → tsek

So badyet is a standard Filipinized borrowing.

Yes. Roaming is an English loanword used in Filipino, especially in telecom and travel contexts.

In everyday Filipino, many technology and service terms remain in English, such as:

• load
• signal
• data
• roaming

So ang roaming sounds normal in modern Filipino.

Yes, you can, and it will still be understood.

However, Depende sa badyet ang roaming sounds more natural because depende sa... is a very fixed, common chunk.

So these are all possible:

• Depende sa badyet ang roaming.
• Ang roaming ay depende sa badyet.
• Depende ang roaming sa badyet.

The first one is especially natural in conversation and neutral writing.

No, nothing is missing.

Filipino often forms equational or descriptive sentences without ay:

• Mahal ang cellphone.
• Mabait ang guro.
• Depende sa badyet ang roaming.

The particle ay can be added when the topic comes first:

• Ang roaming ay depende sa badyet.

So:

• Predicate first: usually no ay
• Topic first: ay is often used

A simple learner-friendly pronunciation guide would be:

• Depende ≈ de-PEN-de
• sa ≈ sah
• badyet ≈ bad-YET
• ang ≈ ahng
• roaming ≈ RO-ming

Approximate full pronunciation:

• de-PEN-de sah bad-YET ahng RO-ming

Notes:

• ng in ang is pronounced as one sound, like the ng in song
• badyet has a dy sound, similar to j in some pronunciations

The pattern is:

• Predicate + topic

More specifically:

• Depende sa badyet = predicate/comment
• ang roaming = topic

This is a very common Filipino pattern. Compare:

• Mahal ang kape. = Coffee is expensive.
• Masarap ang adobo. = Adobo is delicious.
• Depende sa badyet ang roaming. = Roaming depends on the budget.

So this sentence is structurally very typical in Filipino.

Yes. This structure is very productive.

Examples:

• Depende sa badyet ang biyahe. = The trip depends on the budget.
• Depende sa panahon ang lakad. = The outing depends on the weather.
• Depende sa schedule ang meeting. = The meeting depends on the schedule.

So once you learn depende sa + noun + ang + topic, you can use it in many situations.
