Why can't Samsung Dual-Card Telecom Card 2 connect to the network s5?

It is recommended that you try 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 online service of data traffic.

2. Check whether the "Move Data" switch is turned on.

Slide your finger down the screen top curtain, slide the shortcut bar to the left, and turn the "Move Data" pointer into green.

3. Reset online parameters.

In standby mode, select Standby Screen-Applications-More Settings-Mobile Network-Click Access Point Name-Menu-Reset to Mute Settings-After the settings are completed, restart the mobile phone to surf the Internet.

Please change a calling card.

5. You can also try again in another time period or network environment.

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

If the fault still exists, it is recommended that you send your mobile phone to the nearest Samsung service center for testing and maintenance.

It is recommended that you apply for "booking to the store" in Samsung official website and enjoy priority maintenance service:/pre-order.

After the appointment is successful, please bring your machine, invoice and warranty card to the service center you reserved on time.
