Hello. You do need data access to see all available tiles for your carousel. I found this from the manual, pg 44.

Note:

updated, and there are dozens of tiles to choose from.

The following table shows a sampling of the default tiles

that may be preloaded on your phone.

You only have a predefined number of tiles preloaded to you phone. To get more, you have to be connected to the internet to see the catalog. If you're not on an everything data plan which is sounds like you're not, you can add data access as an attachable and remove it when you're done getting what you need.

This content, the tiles for your Sprint one-click carousel, can only be downloaded from a compatible phn like the Samsung Restore, because these phns have an embedded URL that's part OF the carousel so it knows where to go on the internet and get new tiles. There's simply no other way to get this type of content. Could it have been that when you first activated the phn, your data WAS active. Or have I misunderstood when you said you don't have a data plan, that your data IS active but you have a casual data plan. Can you connect to the web?

Hello again. Sorry for the delay in responding to your questions. In short, you WILL need the internet on your phn to customize and get what you need and then it can be blocked again.  There simply isn't a way to use a computer to do this. For one, we wouldn't know what the URL actually is to go and get these tiles as it's embedded in the carousel application. And second, even if you can connect your phn to a computer for pics and music transfer, the folder for the carousel application could not be seen this way, meaning, there would be no way to transfer it to your phn even if you could get it on your computer.
