@GingerThe sim card doesnt control content on the phone.
If Android check if it has backed up to Google
If Apple check if it has backed up to iCloud.
If neither of these then your data may be lost for ever, unless you can get one of the data recovery companies to try and get the data off of the device.
Other than that without knowing the Manufacturer and Model we cant give any more help apart from the generic info i gave above.
- Xperia 1V - o2 and Spusu
- Pixel 8 Pro - o2 and Vodafone UK
