I bought a Huawei mobile phone in JD.COM, but I can't receive short messages, and the speed of sending short messages is also very slow. It has been seven days since this problem was discovered, but within 15 days. If you don't receive SMS or verification code, it may exist in the following situations:

1, check whether the mailbox is full. If it is full, please delete some information;

2. If you still can't get it after deleting it, I suggest you change the machine or card to see if it is caused by hardware;

3. Check whether it is intercepted by mobile phone interception software;

4. Check whether the cell phone signal is normal and try to test whether it can be received in other places.

After the above reasons are eliminated, it still cannot be used normally. Please contact the local manual customer service to handle this problem.
