Case 1: The brands and systems of the old and new mobile phones are the same, such as iPhone6 and iPhone. You can use iCloud to synchronize the data in the two mobile phones.
Case 2: The brands and systems of the old and new mobile phones are different, such as Android phones and iPhone. Third-party tools can be used to synchronize mobile phone data. Contacts can synchronize QQ address book with SIM card, and photos can be synchronized with network disk software. The content of the post-it note can be imported into the post-it note of the old mobile phone first, and then log in to the same post-it note account on the new mobile phone. The method for quickly transferring the contents of the old mobile phone to the new mobile phone is as follows:
1. Two mobile phones turn on Tianyi Cloud at the same time, and change the machine with one button.
The old mobile phone chooses to export data, and the new mobile phone chooses to import data.
Your old mobile phone and your new mobile phone.
What kind of mobile phones are old and new? It would be very convenient if they were all smart phones. First back them up as files (both applications and data can be used), then find the directory of the backed-up files and copy the backed-up files to the new phone to restore the backup (this function can also be realized by third-party software in the computer, with the same principle). If the old mobile phone is a smart phone and the new mobile phone is a non-smart phone, or conversely, the new mobile phone is a smart phone and the old mobile phone is a non-smart phone, it will be more troublesome. Applications can hardly be backed up (because smart and non-smart applications are mostly incompatible), and the only things that need to be backed up are phone calls and text messages. Making phone calls is relatively easy. Find a blank mobile phone sim card (the current sim card is 64k card, which can store 250-750 calls), and then use this sim card as the transmission medium, that is, first copy the number to the SIM card in one mobile phone, then change the SIM card to another mobile phone, and copy the number on the SIM card to the new mobile phone. SMS is more troublesome, because sim generally stores fewer SMS messages. If there are many short messages in the old mobile phone, you can only copy and transfer them part by part (that is, repeat the operation several times or more), instead of copying, use the transfer function (that is, the "cut" function in the computer), otherwise the same short messages will be copied every time.
