Do you usually use LINE? It’s a Japanese application which is similar to SMS and now it’s spreading over the world. Actually my foreign friends such as Korean, Chinese, Thai, Turkish, Colombian, etc. use LINE to keep in touch with me. The speed of sending and receiving is really smooth and you can see if the receiver already saw the message or not. Of course, you can send picture or short movie same as e-mail. Also it has some other functions like cute stamps, free call and sound message. It’s very useful and fun to use. I think LINE is better than SMS today. If you’re still not LINE user, just try once. You’ll be a slave of LINE!
