Only thing I can think of is plugging your old sim card into another device and saving again as a file on your old playthrough, then loading the save file on your new device. Would just require a little juggling to move the file over to the new device, but I'm not at all versed in save compatibility across phones, and if they have a different OS, it might be moot anyway.
I'd just use a save editor to get your character how you want them and catch up on progress. Might be the only option.
