# Does a SIM card hold storage? — Adinand Auto File Sorter Last reviewed: September 25, 2026. HTML version: https://adinandsorter.com/answers/does-a-sim-card-hold-storage **Not for your files. Photos, videos, downloads and apps are never stored on a SIM card; what a SIM can hold is a limited number of contacts, and Samsung says outright that it was not built for storage.** If your phone takes a second card for files, that is a microSD card, and it is a different thing. ## What a SIM can hold

Contacts, and not many. Samsung's contacts page puts it plainly: "SIM cards are not designed for storage and can only hold a certain amount of contacts" ([*How to manage, save or copy contacts on your phone & sim*](https://www.samsung.com/uk/support/mobile-devices/how-do-i-manage-my-contacts/), Samsung UK, read 25 September 2026). It does not give the number, and we have not found a Samsung page that does. Contacts kept only on the SIM also lose a feature: "You cannot set a custom ringtone for contacts that are stored only on the SIM card" ([*Manage your contacts with ease on your Galaxy phone and tablet*](https://www.samsung.com/us/support/answer/ANS10001943/), US edition, read 25 September 2026).

An eSIM is different again. Samsung lists the places contacts can live as "USIMs, a user's Samsung/Google account, and eSIMs, which utilize the device's storage", and adds that "For devices running One UI 6.1 or later, the eSIM Contact saving function is no longer supported" ([*eSIM Contact saving function support discontinued*](https://www.samsung.com/latin_en/support/mobile-devices/esim-contact-saving-function-support-discontinued/), Samsung Caribbean, read 25 September 2026).

## Where your files actually are

Android's storage overview counts two physical places: "Android provides two types of physical storage locations: internal storage and external storage", and "Removable volumes, such as an SD card, appear in the file system as part of external storage" ([*Data and file storage overview*](https://developer.android.com/training/data-storage?hl=en), read 25 September 2026). A SIM card is not among them. Samsung's own file guide says the same in everyday terms: the phone "has a massive internal storage", and if it fills up you can move files "to an external storage system, such as a microSD card" ([*Manage files on your Galaxy phone or tablet*](https://www.samsung.com/us/support/answer/ANS00076845/), US edition, read 25 September 2026).

The practical upshot: moving your SIM to a new phone may carry a few contacts across. It does not carry a single photo.

## Getting contacts off the SIM

If you have been relying on the SIM for contacts, copy them somewhere sturdier. Google's steps: "Insert the SIM card into your device", open the Contacts app, tap **Organize** › **Manage SIM**, pick the contacts and the account, and tap **Import**. The SIM keeps its copy: "After you import, the contacts are still in your other account" ([*Import your contacts into Google Contacts*](https://support.google.com/contacts/answer/15147365?hl=en&co=GENIE.Platform%3DAndroid), read 25 September 2026).

Google can also do this continuously, through a switch named "Backup device-only & SIM contacts automatically", with the caveat that it "depends on your device’s make and model" ([*Back up & sync device & SIM contacts*](https://support.google.com/contacts/answer/9423168?hl=en), read 25 September 2026). On a Galaxy phone, Samsung's route is Contacts › Manage contacts › Import or export contacts, and for a phone swap it points you elsewhere: "the Smart Switch app makes the process quick and easy" (Samsung UK contacts page above).
