Unicom users send international short messages to Holland. Why can't they send them out?

What should I do if my mobile phone can't send international short messages?

1. Check whether the mobile phone is in arrears;

2. Check whether the method of sending international short messages is correct. The correct sending method is 00+ country/region code+user number;

3. Check whether it is normal to send text messages to other mobile phone numbers;

If you still can't suggest Unicom 100 10 to report the situation.
