Model number questions
What is my phone model number?
It is the code the maker assigns to your exact phone, such as CPH2667 or SM-S938U1. On the phone you are holding, it sits in Settings → About phone (iPhone: Settings → General → About), on the retail box, and often on the SIM tray. The live check on the home page shows it too, when the browser is willing to share.
Is the model number the same as the model name?
No. The name is what marketing calls the phone — Galaxy S25 Ultra. The number is the code printed on it — SM-S938U1. Several numbers can carry one name, because a phone sold in different markets gets a different code.
What does the letter after a Samsung code mean?
It is the market. U1 is a US factory-unlocked phone, U is a US carrier phone, B is international, W is Canada, N is South Korea, and 0 is China. A trailing /DS means the retail unit has dual SIM.
