Frequently asked questions
Will a hard reset delete everything on my Nokia Lumia 638?
Yes. A hard reset (also called a factory reset) erases all apps, photos, messages, and accounts, returning the Nokia Lumia 638 to its out-of-box state. Back up anything you want to keep before starting.
Does resetting the Nokia Lumia 638 remove the SIM lock or carrier lock?
No. A hard or factory reset only clears data and settings — it doesn't remove a carrier/SIM lock, which is tied to the device's IMEI at the network level. You'd need to contact your carrier for an unlock.
How long does a factory reset take on the Nokia Lumia 638?
Typically a few minutes, though it can take longer on older or heavily used devices as more stored data has to be wiped.
Does the Nokia Lumia 638 lock to an account after a reset?
Usually not — Factory Reset Protection (FRP) and Activation Lock are Android and iOS features. Most other platforms, including this device's, don't add an account lock after a reset.
How do I format my Nokia Lumia 638?
"Formatting" and "factory resetting" mean the same thing for the Nokia Lumia 638 — both erase all data and restore default settings. Use whichever method above matches your situation.
Can I factory reset my Nokia Lumia 638 without the password?
Yes — the reset methods above don't require your lock screen password, since they bypass the normal login screen entirely.
Does my Nokia Lumia 638 have a hard reset button?
Not a single dedicated button — the Nokia Lumia 638 uses a button combination instead of one labeled "reset." See the Hard Reset section above for the exact keys to press.
