Why can't Betty Wong rent a Guangdong Unicom card from 9 yuan with 300 megabytes of traffic?

General mobile phone can't send SMS processing method is as follows:

1. I suggest you change your mobile phone and see if you can send and receive short messages.

2. If you can send and receive short messages, I suggest you plug the card back into your mobile phone and send yourself a short message to see if you can receive it.

3. If not, check whether the number of SMS center is set correctly. The number of Guangdong SMS Center is as follows:

The number of SMS service centers in Guangzhou, Zhuhai, Shaoguan, Huizhou, Zhongshan, Jiangmen, Zhanjiang, Maoming, Zhaoqing, Qingyuan, Yunfu, Foshan and Yangjiang is+8613010200500;

The number of SMS service centers in Shenzhen, Huizhou, Shantou, Chaozhou, Heyuan, Meizhou, Shanwei, Jieyang and Dongguan is +86 130 1088500.

If all these methods have been tried, the mobile phone card can't send short messages on other mobile phones. I suggest you bring your mobile phone card to the local business hall for testing or replacement.
