What if Xiaomi's mobile phone can send text messages and make phone calls but can't surf the Internet?

Confirm with the operator whether the traffic limit standard has been reached or whether the data network function has been enabled. If necessary, you can replace the SIM card that can surf the Internet normally to confirm. Check the cell phone signal. If the mobile phone uses a metal or magnetic protective case or bracket, the protective case and bracket will affect the signal of the mobile phone. I suggest you take it off and try it.

Wait until the settings are completed, and then try to surf the Internet. If not, please restart and try again.

If the mobile phone can't surf the Internet normally, troubleshooting can be carried out according to the following conditions: 1, the contact between the SIM card and the metal contact of the mobile phone is insufficient, and the SIM card can be reinserted. In case 2, if the SIM card is damaged or the mobile phone has a problem, you can change the machine to check to see if there is a problem with the SIM card or the mobile phone.

Mobile phones can make calls, but they can't send text messages to the internet. There may be the following situations: First, the mobile phone has not opened a traffic packet; The second is that although the mobile phone has opened the traffic packet, it has not opened the mobile data on the mobile phone settings or connected to wifi；; The third possibility is that the mobile phone is faulty.
