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).

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

  2. Remove

  3. Press

  5. Insert
    the new SIM card until it clicks in the slot
  6. Replace
    the battery
  7. Replace
    the cover
  8. Start
    the device

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
