Does Unicom need to set the SMS center number when sending SMS abroad?

China Unicom has set up a short message center number for USIM card users. Users can send and receive short messages directly. The parameters involved in sending and receiving short messages abroad are exactly the same as those in China, and users do not need to make any changes to the parameters involved in short messages before leaving the country.

If the user needs to set the SMS center number, please consult the local customer service telephone number 100 10 to get the SMS center number of the user (Unicom's SMS center number must be set to+8665438+8613010xx500).

-Select Information → Select → Settings → SMS → Information Center in use.

-USIM card information center: "the number of the SMS center to which the user belongs".
