Also question is, will a factory reset affect my SIM card?
Microsoft's Windows 8 and Windows 10, and Apple's macOS have options for this. On Android devices, there is a factory data reset option in Settings that will appear to erase all of the device's data and reset all of its settings. Data on the SIM card and the microSD card is not erased.
Additionally, can you wipe a SIM card? There is a risk - simple deleting or resetting can not really erase the data, SIM card data recovery software can make deleted data recovery possible. Therefore, you need to rely on a professional data eraser tool like this Android SIM Card Eraser (Windows/Mac). With it, you are free to fully wipe out Android SIM card.
Likewise, people ask, can you do a factory reset without a SIM card?
Even if no SIM card is in the device, you can reset the iOS software normally; apps and functions that require mobile service won't work until the SIM card is in the phone, but the iOS software will still work normally. Add a SIM card before or after resetting the iPhone to connect to your provider's network.
Does a factory reset delete everything?
Factory Reset does NOT delete all dataWhen you factory reset your Android phone, even though your phone system becomes factory new, but some of the old Personal information is not deleted. This information is actually “marked as deleted” and hidden so you can't see it at a glance.
