What if Samsung's mobile phone can't access the Internet?

According to your description, I suggest you try the operation according to the following steps.

Restart the phone

Restart the phone (so that the phone can search and register again).

Select a network operator

Under the standby desktop-click Application-Settings-More-Mobile Network-Network Operator-Search Network-Select the network operator supported by your SIM card.

Wipe the contact point between the mobile phone card and the mobile phone.

Wipe the contact point between the mobile phone card and the mobile phone (whether the sim card is in poor contact).

Replace SIM card

Try to replace the sim card (whether the SIM card is aged or damaged).

Restore the backup data to factory settings.

Back up mobile phone data (phone book, SMS information, multimedia materials, etc.). ) and restore the factory settings of the mobile phone (excluding whether it is due to software).

Contact Samsung service center

If the problem persists, there may be a problem with the system or hardware. I suggest you contact Samsung Service Center for testing. For specific inquiries about the service center, please visit.
