What area code should China Mobile add before sending SMS to Thailand?

First of all, you have to go to the mobile business hall to handle the one-yuan international SMS function.

The area code of China is +86, and that of Thailand is 0066.

If it is China Mobile, open international long-distance service first, and then dial 1795 1+ Thailand's country code+phone number.

The country code of Thailand is 0066, and then the first 0 of the phone number is removed.

For example, your friend's phone number in Thailand is 0837656569.

Just call 0066837656569.

No matter what call you make, you must first open an international long-distance service.

But you'd better use VoIP. International calls are too expensive.

Or ask your friends to call you. Many cards in Thailand make international calls for only 20 cents a minute.
