In Shenzhen, mobile phone cards can't send short messages (extra points)

There are two possibilities.

1, roaming function is not enabled for your number;

2. It may be that your number data failed to upload data when roaming.

Generally, these two methods can be solved by calling your 10086. It is recommended that you have a password for your own number. If there is no password, it will take a long time.

In addition, you can check your SMS center number.

The regular number is +86 1380 * * * 500, and the middle four digits are your local area code (Shangqiu, Henan). Even if I go to the business hall of Shenzhen Mobile, I will tell you that the foreign number cannot be solved in Shenzhen. I suggest you make a phone call to confirm before you go to the business hall. You'd better call Shenzhen Mobile Xinzhou Business Hall to confirm.
