I want to buy an iphone. I heard that iphone can send international short messages, and it is free ... Is it true? I sent it from China to Korea. Will it work?

Regardless of mobile, China Unicom, telecommunications, international SMS is opened by default, and it does not need to be opened through customer service.

As long as you know the country code+phone number, you can send text messages directly, but you can't dial the phone directly. You can buy a long-distance telephone card.

Opening an international call requires a deposit of 2000 yuan, 0.2 yuan /6 seconds, that is, 2 yuan/minute, but the billing is based on 6-second hops, which is more cost-effective for users.

For international video calls, if you need to make video calls with friends and relatives abroad, it is recommended to use QQ and other chat tools, and the video is free.

International SMS fee: 1 yuan/article.

..... Upstairs, as the news said, the iPhone5 only provides the function of supporting multiple networks, and the use of the SIM card is cancelled. Just like the current CMDA version of iPhone4, it can only use the method of burning numbers (similar to the previous PHS method), and does not specifically point out that sending international short messages is free.
