Unicom card can surf the internet, but it can't send text messages and make phone calls. When you make a phone call, it will beep three times.

Hello, I'm glad to answer your question.

Please take your mobile phone and card to the business hall to find a salesperson for testing. If it is a card problem, please change the card. It's a cell phone. You can apply for after-sales service.

If my answer is helpful to you, I hope you can adopt it, thank you!

If you don't understand anything, you can ask me questions, or ask my team questions later. Give someone a rose, the hand has a lingering fragrance! Help others and be happy!
