Why can't I surf the Internet on my mobile phone after traveling abroad?

If the mobile phone can't access the Internet with data traffic, it is recommended to do the following steps:

1. Check whether the SIM card has GPRS Internet service or is temporarily closed.

to use the data access function of the mobile phone, the calling card needs to open the data traffic access service. You can contact the local network provider of the calling card to open the data traffic online service.

2. check whether the "mobile data" switch is turned on.

slide down the screen top curtain with your finger and turn the "move data" point to green.

if you still can't surf the internet after the above operations, it is recommended to reset the mobile phone's surfing parameters: Settings-Mobile Network-Access Point Name-More-Reset to the default settings.

3. Please try another calling card.

4. You can try again at another time or in a network environment.

5. Back up mobile phone data (phone book, SMS, pictures, etc.) and restore the mobile phone to factory settings

If the fault still exists, it is recommended to send the mobile phone to the nearest service center for inspection and maintenance.
