When you see “GSM” in a ROM title, it usually means the firmware is for the international or carrier-unlocked variant that uses a SIM card for everything.

Security analysis sites have noted that while the site is functional, it is not always verified as "safe" or "legit" by automated web checkers, meaning users should ensure they have an active antivirus and scan all downloaded zip files before extraction. Official alternatives like SamFirm or Frija (which pull directly from Samsung servers) and Sammobile exist, but gsmrom.net remains a valuable backup for legacy firmware that may have been deleted from official channels.
