How to calculate the mobile Internet traffic when traveling abroad?

different operators have different charging standards. Generally speaking, when you open data traffic abroad, you will be charged separately, or you need to purchase the corresponding international traffic package separately. The cost of using mobile data when leaving the country is not included in the user's daily tariff package in China.

wechat related teams also gave relevant figures of traffic consumption: voice .9-1.2K/ s; Text 1M can send about 1 text messages; Upload the address book, 2K/1 people; The picture is compressed to 5-2K/ piece according to the original picture quality, and the video is compressed to 29-3K/ second according to the original video quality. There will also be a warm reminder: "WeChat has a well-designed communication protocol, which only consumes very little traffic when running in the background, and consumes about 1.7M traffic a month. It is recommended to choose background operation when exiting to ensure timely receipt of WeChat messages. "

There are roughly two types of applications where smartphones generate traffic. One is social and news applications, such as WeChat and Weibo. "There are many large users in Weibo, such as him @, or they refresh frequently, so the traffic must be used much more; If WeChat users join a lot of groups, or the group chat is very active, people often upload pictures in the group friends, and the circle of friends is often refreshed, which will generate a lot of traffic. " The other type is downloading. "Some users will download applications through their mobile phones, and sometimes they may leave WIFI, but the download does not stop, so the traffic consumption is amazing."

in addition to using wechat products, we don't rule out some malicious applications, which will steal traffic without users' awareness, like some fortune-telling or unknown games, so be especially careful when using them. For normal applications, including WeChat, Weibo and QQ, choosing to quit completely when not in use will avoid the consumption of background traffic.

It is suggested that users who leave the country should use WIFI as much as possible, which is not particularly necessary. During their stay abroad, it is best for users to turn off the' data roaming' item in the settings or the' cellular data' item in Apple's mobile phone, so as to avoid expensive roaming charges. If you really need to use traffic to surf the Internet, you can purchase the corresponding international traffic package separately, turn on the traffic reminder and make careful calculations for your journey.
