This is probably the most complete cheats and secret codes reference for the new Samsung SM-B312E phone you can ever find on the Internet. The main reason I say this is because most of the codes were dumped straight from the firmware (the European version, B312EXXNE6), others, meant for much older models, were also found on the Internet, but almost all of them were then tested on a real device (if the code is not tested, there's a note about this in the "Notes and warnings" column) and a description was made what do they do right here, on B312E. This cheatbook is divided into several parts: information codes, testing codes, setting codes, codes with undefined behavior and general tips and tricks.
Please note: GSM-related USSD codes (such as call divert, Caller ID display etc) are not included here because all of them are common for all GSM phones, their functionality is completely duplicated in standard call settin
