Do I have to go to the business hall to open the international roaming function before going abroad?

You need to open international roaming before going abroad.

At present, users of the three major operators generally need a real-name registration system to open international roaming services.

When international roaming is launched for the first time, 500 yuan's prepaid phone bill is generally needed in the account (GSM users need 1 0,000 yuan). Users can choose to open it permanently or for a short time, and Mobile can open an international roaming account for a short time with prepaid phone charges in 200 yuan.

Real-name registration system users can open it by SMS or in the operator official website or mobile phone client. If you feel trouble, the safest way is to go to the business hall.

With roaming service, there is enough phone bill in the mobile phone account, so you can use your mobile phone when traveling abroad.
