What does 开户 mean exactly here?

开户 literally means to open an account.

Depending on context, it can be used for:

• a bank account
• a mobile phone / internet service account
• a securities or trading account
• other kinds of service registration

In this sentence, because 安装费 appears later, it may be talking about opening some kind of service account rather than just a bank account.

Why is 一方面 used twice?

This is the pattern 一方面……一方面……, which means something like:

• on the one hand ... on the other hand ...
• for one thing ... for another ...

It introduces two parallel aspects of the same situation.

In this sentence, the speaker is saying there are two things involved in opening the account:

1. 实名认证 is needed
2. there is also an 安装费

So the repetition is normal and intentional.

Could this also be 一方面……另一方面…… instead of 一方面……一方面……?

Yes. Both are possible, but they feel slightly different.

• 一方面……另一方面…… is very common and often sounds a bit more polished.
• 一方面……一方面…… also works when you are listing two parallel aspects.

So this sentence could also be written as:

开户一方面需要实名认证，另一方面还有安装费。

That version may sound a little more natural to some speakers.
