I had just factory reset to galaxy S21 and it is asking for aim after reset startup rather than wifi connection. Is it ok or not as i am sending my galaxy S21 to backhome family after factory reset and i had fully paid the device amount and its unlocked device confirmed from network carrier. Thanks
Yeah, if you're just getting a Notification saying that there is no SIM inserted, you can ignore that as the phone was previously registered on your Carrier's network.
You could also go ahead & set it up from the Factory Reset without the SIM & it won't Reset automatically again.
It's not the initial setup, it's after a Factory Reset. So the SIM isn't required. WiFi is all you need.
If the device is brand new & you NEVER put the SIM card in the device, if you set it up without the SIM, it WILL automatically Factory Reset the first time you insert the SIM.
You should still be able to set up the phone, after a Factory Reset, WITHOUT a SIM.
It *SHOULD* give you the option to "skip" when it notifies you that there's no SIM inserted.
Can you post a pic of the screen?
