Android phone can't operate the back button as soon as it enters the text message, which is not easy to use.

Download and install qq Synchronization Assistant on your Android phone, open it and log in to your qq account.

Click the "More" button in the upper right corner and select "SMS Backup" after entering;

Select "Backup to Network" to back up your short messages according to your needs;

Operating on a jailbroken iphone:

(1) Open cydia, search for qq synchronization assistant pro and download and install it;

(2) Open the software. If the jailbroken iphone is not your own, please back up the SMS. You can use another qq number for backup.

(3) Connect the jailbroken iphone to the computer, open itools, delete sms.db(ps: it can be deleted safely after backup, without any influence) in the file system, and then restart the iPhone;

(4) After restarting, open qq Synchronization Assistant to select SMS and restore it to the jailbroken iphone;

(5) Open itools and click itunes backup management in the toolbox to create a new backup of jailbroken iphone; ;

(6) After the backup is completed, double-click the backup of jailbroken iphone, select SMS, double-click sms.db, select Export, and then select the path to save;

Open itools on the computer, connect iphone with data cable, and select itunes backup management in the toolbox to back up iphone.

After the backup is completed, double-click the exported backup, select SMS, double-click sms.db, select Import csv file, and then select the csv file just exported to import and save.

Select "Restore from Backup" in itunes backup management, and be careful not to disconnect the iphone from the computer at this time. After restoring from backup, your phone will automatically restart. Open the SMS to see if the SMS on your Android phone has reached the iphone5s. And the text messages on your iphone won't be lost.

Next, you need to delete sms.db in the /var/mobile/library/sms folder, and then restart it to restore the SMS on the jailbroken iphone. Just use qq synchronization assistant to log in to the qq account that just backed up the jailbreak iphone and restore it. You're finished.

I hope this can help you and I hope you can adopt it. Thank you!
