Full list of MMI and USSD codes

We are looking for someone to compile a FULL list of MMI and USSD codes for Apple and Samsung devices. This list needs to be tested on the latest phones from S10 to current models of Samsung as well as from Iphone 8 to current models of apple phones. All must be tested and working to make it into the list. When you create the list you must also include a description of what the code does as well as how to use it. If you wish to apply please apply with the MMI code that shows the IMEI# of a mobile phone. All Applicants that apply WITHOUT this information will be discarded for failure to read the descriptions. If you are serious about applying for this project do not send your BOT to apply for you.
