How can I tell the customer if the circle of friends can't get through?

If you can't reach your customers by phone, but still want to tell them your travel plans, you can consider posting travel notices in your circle of friends in the following ways:

1. SMS: Post a short message in a circle of friends to inform you of your travel plans. You can include the destination of your trip, the time range of your trip, and the fact that you may not be able to reply to messages or answer phone calls in time during this period.

2. Travel photos: You can share some photos related to travel. This can not only show your travel arrangements, but also show your happy mood and wonderful moments of travel to customers.

3. Status update: You can post status updates in the circle of friends, indicating that you are on a business trip and may not be able to reply to information or answer the phone in time. You can express your understanding and gratitude to customers in the update, and promise to reply to their information as soon as possible after the trip.

No matter which way you choose, you should think carefully before publishing to ensure that your information is clear and polite, and as far as possible, it will not cause misunderstanding. At the same time, make sure that your customers can easily find your travel contact information so that they can contact you when needed.
