Cước thuê bao và phí hòa mạng khá cao.

Cước thuê bao means the subscription charge / subscriber fee.

• cước = charge, rate, fee
• thuê bao = subscriber / subscription

Together, it refers to the regular amount a customer pays for having the service.

Yes, they are very similar, and both can often be translated as fee or charge.

The difference is mainly collocational:

• cước is often used for service charges, telecom charges, postage, transport rates, etc.
• phí is a more general word for a fee or charge.

So:

• cước thuê bao = subscription charge
• phí hòa mạng = connection/activation fee

Using different words here sounds natural because these are standard expressions in telecom contexts.

In this context, hòa mạng means connecting/activating a line or service on the network.

So phí hòa mạng is the connection fee, activation fee, or network hookup fee.

Literally, hòa can suggest joining or integrating, and mạng means network. But as a learner, it is best to treat hòa mạng as a set phrase used for telecom service activation.

Vietnamese often does not use a verb like to be in sentences where English would.

So:

• Cước thuê bao và phí hòa mạng khá cao.
• literally: Subscription charges and connection fees quite high.

This is a normal Vietnamese pattern:

• subject
  • adjective

Examples:

• Giá này cao. = This price is high.
• Nhà đó đẹp. = That house is beautiful.

So the idea of are is understood without saying it.

Khá means quite, fairly, or rather.

It comes before the adjective it modifies:

• khá cao = quite high
• khá đắt = quite expensive
• khá tốt = quite good

So in this sentence:

• cao = high
• khá cao = quite high

This is the normal word order in Vietnamese: degree word + adjective.

Both describe a high level, but the strength is different:

• khá cao = quite high / fairly high
• rất cao = very high

So khá is a bit softer and less extreme than rất.

Compare:

• Giá khá cao. = The price is quite high.
• Giá rất cao. = The price is very high.

Yes. Và is the standard word for and.

In this sentence it joins two noun phrases:

• cước thuê bao
• phí hòa mạng

So the structure is:

• A và B khá cao = A and B are quite high

Vietnamese usually does not mark plural the way English does.

Words like cước, phí, giá, người, etc. can be singular or plural depending on context.

So:

• phí can mean fee or fees
• cước thuê bao và phí hòa mạng naturally refers to those charges in general

If needed, Vietnamese can add words like các to make plurality clearer, but it is often unnecessary.

It sounds fairly neutral and somewhat formal/administrative, especially because of the telecom vocabulary.

Words like:

• cước thuê bao
• phí hòa mạng

are common in bills, contracts, advertisements, or customer-service discussions.

In very casual speech, people might use simpler wording depending on the context, but this sentence is perfectly natural and standard.

The pattern is:

noun phrase + and + noun phrase + degree word + adjective

More specifically:

• Cước thuê bao = subscription charge
• và = and
• phí hòa mạng = connection fee
• khá = quite
• cao = high

So the full structure is:

[Subject: two things] + [description]

This is a very common Vietnamese sentence type:

• A và B khá cao = A and B are quite high

A rough pronunciation guide:

• cước — like koo-uhk with a rising/glottalized tone
• thuê bao — tway bao
• phí — fee with a rising tone
• hòa mạng — hwa mang
• khá cao — kha kow

A few tone notes:

• phí has a rising tone
• khá has a rising tone
• hòa has a falling-ish tone in southern speech / more level-falling in northern pronunciation
• mạng has a heavy, broken tone
• cước also has a glottalized tone

If you want, I can also break the whole sentence down syllable by syllable with Northern or Southern pronunciation.
