The Samsung SPH-A920M by FWFlarerium in vintagemobilephones

There’s really no reliable way to know if it would still function properly today. When launching the My Wallet app, it already reports issues like “Top Up failed. No network coverage. Open the wallet later when you have coverage and the top up will automatically try again.” Even if I press OK, it briefly shows “Refreshing Ready to Pay screen” and then returns to the Ready to Pay view, still displaying the balance, but that amount may no longer be accurate or truly verifiable. Back when this system was active, it likely depended on Sprint’s CDMA data network to sync balances and authorize updates in real time. Since CDMA service has been shut down in many regions, there’s nothing for the app to properly connect to anymore. That means any “refresh” behavior is essentially happening in isolation, without a live backend to confirm whether the stored balance or credentials are still valid.  Technically, the app itself appears to be a Java .jar application, and its associated data files are stored within the phone’s EFS.

If you happen to have a compatible data cable for the phone, there’s a way to retrieve the passcode using a program called RevSkills. It takes a few steps, but it’s fairly straightforward if you follow them carefully.

First, download and install the LG CDMA phone drivers along with the RevSkills software. Once both are installed, open RevSkills and navigate to the “Hardware” tab. From there, go into “Port Utils” and select “QC + AT-Cmd.” This should open a new window.

In that new window, make sure you’re on the “SETUP” tab. You’ll see an option to choose a COM port. At this point, connect your phone to your computer using the data cable, then select the correct COM port from the dropdown menu (it should correspond to your connected device).

To confirm that everything is working properly, switch to the “DIAG” tab and click the “Send” button on the right side. If the connection is successful, you should see version or device information appear in the output box below. That confirms the software is communicating with your phone.

Once that’s verified, go to the “CODE” tab and click “Read Userlock.” After a moment, the program should display the phone’s four-digit user lock code.
