You need to use your mobile phone to surf the Internet in Turkey. What kind of calling card should I choose? Which is the cheapest? Thank you)

I don't know what the situation is in Turkey. I am in Brazil, so I can tell you something about me. In fact, foreign countries are similar.

1. You can use a foreign card for your own mobile phone, unless your domestic card is completely tied up in custom machine, but your Samsung's should be Android, so you can swipe your card.

2. I asked the local people, and I set up an unlimited internet package, 0.5 Brazilian lira a day, GPRS or 3G, and I can also use my mobile phone to connect to a computer. You can't use China card when you go out. It's very expensive. I mean, you have to ask the local people how to do it, and they will teach you. Or just ask the telecom company over there.

3. You can make Internet phone calls and call back domestic hourly 10 RMB.
