The sample wallet shows up in your list of wallets, and is actually treated a bit differently than a regular wallet in that you can look at all the cards and categories, but you can't change anything. "Ok," you say, "I get it! But I don't want to see that in my list of wallets any more." No problem, you can't really delete it since it's not a traditional wallet, but starting with eWallet^® 8.1 for iOS, you can hide it. Just do this:

1. Start up eWallet and press the More button in the lower right corner (three dots)
2. Select App Settings
3. Turn off the Show Sample Wallet button
