Yousi dual-mode mobile phone telecom card can't make calls but only surf the internet?

Hello! I hope the following answers can help you:

According to your description, I suggest you try the following methods first:

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

2. Wipe the contact point between the mobile phone card and the mobile phone (whether the sim card is in poor contact) or try to replace the sim card (whether the SIM card is aging or damaged).

3. Back up mobile phone data (phone book, SMS information, multimedia materials, etc.). ) and restore the phone factory settings.

If the problem persists, it may be a problem with the system or hardware. It is recommended that you choose the nearest Yousi after-sales service center for further testing. I hope my answer can help you.
