Can I send a text message from China to the mobile phone number in Laos? Very urgent

Don't talk nonsense if you don't understand! ! ! I just got back from Laos, and my family and friends often send me short messages from home, without going through international business at all. Each message costs 1 yuan. The number is 00856 (Laos country code)+Laos mobile phone number. If you call Laos' mobile phone from home, you need to open the international long distance function. It only costs 40 cents to send a short message to China by Laos mobile phone. Direct dial is only 1.50 USD, which is much cheaper than calling Laos from China.
