What does it mean for Telecom to send a short message to remind me to open the service of giving away 4G traffic?

According to your description, please confirm whether it is a short message sent to you by China Telecom. You can call China Telecom 10000 for manual service, or go to the front desk of the local telecom business hall and ask the staff to confirm. If the confirmation is true, you can surf the Internet safely without deducting money. In addition, I would like to remind you that attention should be paid to both provincial traffic and domestic traffic. If it's traffic in the province, you still have to pay for roaming online outside the province. I hope my answer can help you and get your adoption. If you need to pay the phone bill and handle general business, please log in to the online business hall of China (Anhui) Telecom. Thank you for your concern and support for telecom products. Wish you a happy life!
