On the Galaxy A51 running Android 10, open Contacts and go to More options > Manage contacts > Move contacts. Choose SIM 1, select the contacts, tap Done, choose Phone, then tap Move. [Samsung’s A51 instructions]

Move contacts from your SIM to the Galaxy A51

  1. Make sure the SIM card containing the contacts is available to the phone. The documented A51 example names SIM 1; if your screen shows another SIM, choose the one that holds the contacts.
  2. Open Contacts, tap More options, then tap Manage contacts.
  3. Tap Move contacts, choose SIM 1, select the contacts you want, and tap Done.
  4. Choose Phone as the destination and tap Move.
  5. Open the Contacts list and check that the transferred names appear there.

Samsung documents this menu sequence for the Galaxy A51 example running Android 10. [Samsung support]

If your A51 shows different menu names

Samsung notes that menus vary with software version and provides older-software alternatives. In Contacts, look for Import/Export, Import or export contacts, or Import contacts. Choose the SIM as the source and Phone as the destination if those options are offered. Depending on the version, the operation may be labelled Import rather than Move.

If Import/Export is missing

Check whether Easy mode is enabled. Samsung says the import/export feature may not appear in Easy mode; its A51 support page gives software-dependent Settings routes for turning it off. Menu labels can also differ by software version, model, and mobile provider. [Samsung A51 instructions] [Samsung support]

What to expect when contacts are on a SIM

Samsung describes the A51 operation as a move, while other Samsung guidance describes importing contacts. Do not assume the procedure leaves a duplicate on the SIM. SIM cards also have limited contact capacity, but Samsung does not give a universal number. [Samsung A51 instructions] [Samsung contact instructions] [Samsung France]
