After a debate in early 2012 between a few designs created by Apple, [[Nokia]] and [[BlackBerry Limited|RIM]], Apple's design for an even smaller SIM card was accepted by the ETSI.<ref>{{Cite web |last=Ziegler |first=Chris |date=2012-03-26 |title=Nano-SIM war: here's what Apple and Nokia want to put in your next phone |url=https://www.theverge.com/2012/3/26/2904153/apple-vs-nokia-4ff-nano-sim |access-date=2024-04-10 |website=The Verge |language=en}}</ref><ref>{{Cite web |title=New SIM card format for slimmer, smaller phones |url=https://www.etsi.org/newsroom/news/398-news-release-1-june-2012 |access-date=2024-04-10 |website=ETSI |language=en-gb}}</ref> The ''nano-SIM'' (or 4FF) card was introduced in June 2012, when mobile service providers in various countries first supplied it for phones that supported the format.
