My friend is in the Philippines and I am in Fuzhou. Do I need money if I send a text message directly to her mobile phone? how much is it?

Yes, one yuan each. If her mobile phone is Chinese, you can send it to her in Chinese. If it is an English mobile phone, you can send it to her in Chinese, but she may not receive it, and it is garbled. She will charge for receiving your information, according to foreign standards. In fact, sending international text messages is expensive and unnecessary. You can use QQ and email. Very convenient. Buy an international one.
