Use this page to transfer files between a device, SD card or computer. Many devices do not have an SD card option, such as Apple devices. Check common procedures to see if a device has a SD card. You can also transfer files using Samsung Smart Switch or Samsung Kies.

SD card

SD card memory size and speed ratings vary by OEM. Using an SD card without the proper speed class may work for basic storage. Advanced features like HD video recording, transferring files, or apps that use the SD card, it is likely to cause freezing, crashes, slowness, or errors. If you see these problems with an SD card inserted in a smartphone, upgrade to a faster SD card. Refer to the following classifications to assist in determing the SD card that will work best with your smartphone.

  • Memory size: Limits vary by smartphone, check the tech specs to determine what size is supported.
    • The storage or size of the SD card refers to how much memory the card has to store music, pictures, videos, apps, or other files.
    • A higher-capacity card increases the amount of data that can be stored. Most smartphones can only take SD cards up to a certain size limit.
  • Size: This refers to the physical size of the card. Most smartphones take micro SD cards.
  • Speed class: T-Mobile recommends SD cards with Class 6 or UHS Class 1 or higher. SD card speed classes are different from speed ratings.
    • Rated Speed is maximum speed of the card and also what you would expect to approximately see in typical usage of writing or reading files on the card.
    • Speed Class is a minimum speed based on a worst case scenario test. The class is printed on SD cards as an even number inside a C. UHS class is an odd number inside a U. This is usually a single digit and can be read as MB/s. For example if an SD card had a U rating of 1, the speed class would be 10 MB/s. The higher the class, the faster data can be consistently recorded, read, or transferred on the phone. T-Mobile does not recommend based on rated speed.
