Shaanxi xi 'an Unicom number is prepaid, but there is no international call. Can I send text messages on my cell phone?

Unicom prepaid users do not need to apply, and by default open international long-distance services in Hong Kong, Macao, Taiwan, Malaysia, South Korea, Vietnam and other regions and countries. I suggest you confirm whether this number is a prepaid package or the international call function has been cancelled for some reason. If yes, you can directly call the local 100 10 or go to the local business hall for consultation, but you can't handle it by SMS for the time being.
