Unicom's service is too bad. I didn't open international roaming and international long distance. Why did you text me that I opened it?

If you use the prepaid package, prepaid users do not need to handle international long-distance services, but they will open international long-distance services in Hong Kong, Macao, Taiwan, Malaysia, South Korea, Vietnam and other regions and countries by default, and prepaid 3G cards do not need to handle international roaming services. Automatically open to Korea, the United States, the Netherlands, New Zealand, France, Spain, Britain, Germany, Egypt, Japan, Singapore, Italy, Thailand, Canada, the United Arab Emirates, Malaysia, Vietnam, the Philippines, Kazakhstan, Tajikistan, Russia, Turkey, Australia, Belgium, Switzerland, Indonesia, Estonia, Austria, Sweden, Finland, Slovenia, Austria. If you meet the above conditions, you can use your international roaming and international long-distance functions normally without self-service. For details, please contact local customer service.
