Why can't mui work properly in the browser? Do I have to debug it in my mobile phone?

If your mobile phone can't surf the Internet normally, please check the following:

1. If you don't restart your phone after upgrading to the 4G package, you won't be able to use the Internet function normally.

2. Confirm whether there is a network. I suggest you use it in a place with strong signal.

3. Check whether there is any phone bill in the account. If the balance is insufficient, it needs to be recharged before it can be used;

4, can be turned off for 3-5 minutes, restart the phone and try again;

5. Check whether the USIM card is inserted. If it's plugged in and still doesn't work, I suggest you go to the business hall to check whether the USIM card is faulty or not.

6. If the traffic reaches the peak in that month, the network will automatically shut down. We suggest you pay attention to our SMS reminder or inquire about the package product description.
