Why can't Samsung mobile phone get on the easy car network?

Dear Samsung users: Dear Samsung users: According to your description, I suggest you try the following steps: 1. Check whether the SIM card has GPRS internet service or is temporarily closed. To use the data access function of the mobile phone, the calling card needs to open the data traffic access service. You can contact the local network provider of the calling card to open the online service of data traffic. 2. Check whether the "Move Data" switch is turned on. Slide your finger down the curtain at the top of the screen and turn the Move Data pointer green. 3. Please try to change another calling card. 4. You can also try again at another time or in a network environment. 5. Back up mobile phone data (phone book, text messages, pictures, etc. ) and restore the phone to the factory settings. If the fault still exists, it is recommended that you send your mobile phone to the nearest Samsung service center for inspection and maintenance.
