Differences Between Real iPhone and iPhone Clone?

URGENT: Hello there, I wanted to ask a few questions about real iPhone and the clones. I'm planning to buy a clone iPhone 6s but I'm concerned about some stuffs like;

1) Can you call or text someone with the clone one?

2) Will it get easily broken when came in contact with hot water or when it drops on the floor?

3) The SIM card, is it possible to use the SIM card from my old phone? If I could, will the apps/songs I downloaded on the SIM card function properly on the clone iPhone like it. Supposed to on normal phones?

4) And lastly, if I wanted to buy earphones and chargers do I buy the original ones or the fake ones too?

1. A clone is basically just a basic phone that can call, text and take photos. You can't download any apps, it won't sync with your computer, it doesn't use iCloud or iPhoto, it doesn't work with iTunes
2. Yes the clones break much easier than a real one as they are made of cheaper materials. If you drop it once it will break. And it will be ruined by any contact with water or even moisture like high humidity
3. If you used your old SIM it would only transfer the contacts, not any apps as the clones do not support any Apple apps.
4. You can buy any earphones and chargers

There's no reason to buy a clone. Instead of a clone just buy a cheap Nokia phone that has more functions and you can download android apps

For the record, don't buy a clone. They are no good. Period. Will answer the questions anyway

1. Yes, they are still phones, not very good ones, but still phones
2. Very likely. Durability is clearly not one of their strong points
3. Yes. SIM cards are not memory cards, so they don't hold apps, media, etc, so no that wouldn't work (in any phone)
4. They should support 3.5mm like most other phones & since it is not a legit iPhone it wouldn't be able to work their legit chargers.
