Recently, when I went to update my Verizon-branded Samsung Galaxy S4, I received a message that said, "Software update is temporarily unavailable" (Figure A). I reset the phone to factory defaults, connected to Wi-Fi, disconnected to Wi-Fi, but nothing seemed to work.
Finally, inspiration struck and I solved the issue.
The dreaded update error on display.
There are no apps or settings you can install or configure that will solve this issue. The only way to correct it is by replacing your phone's SIM card. Period. So, before you waste any more time trying to get your phone updated, call your provider and tell them you need a replacement SIM card. If they ask, tell them why. If they instruct you to reset the phone to factory defaults, inform them that solution will not work. If they don't seem to follow your logic, take the device to the provider and show them.
Once you have your new SIM card, you'll need to replace it with the one currently in your device. If you've never replaced a SIM card, it's simple. Every device will vary, but the basics are the same:
- Remove the back of the phone
- Remove the battery
- Press the edge of the SIM card inward to release the locking mechanism
- Pull the SIM card out (Figure B)
- Insert the new SIM card until it clicks in the slot
- Replace the battery
- Replace the cover
- Start the device
Replacing the SIM on a Samsung Galaxy S4.
Once you have the SIM replaced, check again for an update. This time around, the process should continue, and the update be available for installation.
I've heard that a large number of people are told (by nearly every provider) that the resolution for the update issue is a factory restore. However, that's simply not the case. The only way to resolve this issue is with a new SIM card. With that new SIM in place, the upgrade should go off without a hitch.
