4G problem

Hello, ​@EDUARD Bela 

Thank you for your message. 

​@Guimas provided great help. Please confirm whether the situation has been resolved.

If the problem persists, you can also try:

• Removing and reinserting the SIM card;
• Testing the SIM card in another phone (if possible);
• Trying the connection in a different area, if you can.

We look forward to your feedback.

Thank you.
