At present, people and mobile phones in Taiwan Province Province can't receive short messages.

Hello, if you confirm that the international roaming function is enabled, it cannot be used normally. Please check whether the local signal is normal and whether the mobile phone number is normal. I suggest you log in to the mobile phone business hall to check the number status "My-My Basic Information-Current Status". You can try to manually search the local network connection and restart the phone. If it still doesn't work, it is recommended to contact the customer service consultation number by other phones. Non-Unicom numbers need to be charged according to the number fee when calling customer service hotline abroad.
