I had to backup reset my phone. I am trying to access my backup on Verizon Cloud and when I try to sign in from my phone I get the message "Account is in invalid state (code:403)" How can I access my backup?
Error Code 403 is a general error code and generally all error codes are not logged with an actual reason. Normally, an error can give a range of error codes (for example when your browser cant connect you may see the common error 404: Not Found) 404 Not Found is REALLY general. What can it not find?! Unless you scroll through and read scripting or debug files line by line, you may never know. But, error codes are given a reason with certain variables or parameters. For example, Not Found is the problem type, variables can be 'No connection' so it may display error codes 400-405, each error between 400-405 can be a different variable.
These codes can be broadly classified into two main categories USSD codes and MMI codes. While mostly not very useful to the average smartphone owner, these hidden codes can be used once in a while just to satiate your curiosity. The purpose of this article, therefore, is to create a comprehensive list of these secret codes for Android devices.
While the average user might not even need to know the difference between these two, it is always good to know what the differences are. Both USSD and MMI codes usually begin with an asterisk or a pound symbol/hashtag. These codes are updated regularly as new versions of Android software are released, and some manufacturers have their own additional special codes.
The code entry procedure is very simple and only requires you to bring up your dialer keypad and enter the appropriate number sequence. It's important to note that some codes are carrier-specific, so they won't work on all devices. So if your phone doesn't respond to a code, don't dwell on it, just move on and find another one.
USSD stands for Unstructured Supplementary Service Data, and these codes are typically used to communicate between your smartphone and your mobile network operator. This also means that you almost always need to be connected to your carrier for USSD codes to work.
In the past, USSD codes were used to start/stop specific value-added services. They were also helpful in letting you know about the data usage and prepaid balance and accessing a whole lot of carrier-specific information.
While these are still used by smartphone enthusiasts, USSD codes have largely fallen out of favor among general users because most carriers have their own app/website where most of this information could be easily accessed. USSD codes are typically carrier-specific and will differ from one carrier to another. You will need to contact your carrier for the ones relevant to you.
These codes are mostly universal and should work on all Android devices, no matter the manufacturer. There might still be carrier restrictions on certain codes, though, so they're not all guaranteed to work.
These aren't the secret ones, but they're not so well known. USSD, or Unstructured Supplementary Service Data, codes connect to the phone's network once dialed to perform certain functions, like finding out how much credit you have left on your prepaid phone or how much data you've used this month. They change often, and the codes vary from carrier to carrier. Here are a few you can try for some of the major US carriers, along with links to more carrier-specific codes:
