What is the difference between mobile data and roaming data? If there is data in the mobile phone card, can the roaming data be turned on?? Or are they all open??? Urgent!!!

Hello dear, 1Mobile calling data refers to the Internet access function of the mobile phone card, that is, the GPRS function, which is enabled by default when opening an account, and can be turned off if you don't want to access the Internet. Roaming data refers to the data that is used outside the province or abroad.

The roaming data is mainly for the identification of mobile phones when switching operators for international roaming, and the international roaming Internet access will be affected after it is turned off. 2.Mobile data network roaming refers to the use of mobile data to access the Internet in other places (not the place where the number belongs), and the current mobile data network roaming is mainly divided into roaming outside the province and international roaming.

3.At present, the traffic is mainly divided into intra-provincial traffic** and domestic traffic** (excluding Hong Kong, Macao and Taiwan), and the international traffic is preferential and land-packed. 4.

If you only subscribe to the provincial traffic**, the traffic** cannot be used after leaving the province, and the traffic fee generated by the Internet will be deducted according to the tariff** used, and a high traffic fee will be generated at this time. Hope it helps

Hello yo dear, I'll help you solve this problem The specific solution is as follows: the mobile phone goes outside and only turns on data roaming, but does not turn on mobile data to access the Internet pro 1: Data roaming refers to the traffic generated by the use of non-mobile phone number in the attribution place, you can choose to turn on if you need to go online, and you can choose to turn it off if you don't need to.

2: For example, some Internet users specify that the number of delayed traffic in the province and outside the province is different, if the traffic outside the province exceeds the ** traffic, then the charge will be increased when roaming to other provinces. 3：

In general, it means that the data is uploaded to a web server for storage, and the data can be manipulated anywhere. This data can be text, audio, and video, as well as other data that is relatively safe in the cavern. Such as QQ network hard disk, we can upload some files, and then in the field to ** shirts without having to bring a memory card.

Data roaming can be when an off-site client logs in to view the roamed files. Hope it helps
