How to delete data from your smartphone permanently
The above list shows you that your mobile device is a mine of personal information. You certainly don't want this to be made "public". To avoid this, you need to delete all "sensitive" data securely and permanently before you get rid of your mobile device.

- Apple iOS : Settings > General > Reset > Erase all content and settings
- Android : Settings > Privacy > Factory data reset
And for Windows devices? It's not as simple. Research is still underway to find the best way of deleting data from this type of mobile device. Got a Windows smartphone? Please visit the manufacturer's website or read the operating instructions. This will help you find ways of deleting your data.
Don't forget your SIM card and your memory card
Deleting the information saved on your smartphone is good, but think too about the data on your SIM card and/or your memory card.
As far as possible, try to keep your SIM card when you change your smartphone. That way, you shouldn't have to worry about the data saved on it as they will be transferred directly to your new phone. If, however, your SIM card is not compatible with your new smartphone (sizes may vary), ensure that you transfer your data via your operator and then destroy your old card. Don't simply throw it in the bin, cut it up using scissors.
You may perhaps also have a memory card in your smartphone. This enables you to store more photos, videos, etc. Don't forget to remove it before getting rid of your phone! It can be reused with other devices, like an external hard drive. If you can't or don't want to keep your memory card, destroy it in the same way as your SIM card.
the memory card is often hidden behind the phone battery.
