@Conna Is it a micro sim you need or a nano sim, as most new phones use nano size these days. Most sims also have perforations to enable you to pop out the right sized sim.
Hi @Conna , happy Monday! There's some good information above from @MI5 and @Bambino so I hope you're all sorted with your SIM. Don't hesitate to post again if you have any additional questions at any point!
