TheAdventofSIMCards
TheSubscriberIdentityModule(SIM)cardwasinitiallyintroducedin1991,anditrevolutionizedthetelecommunicationsindustry.SIMcardswereanessentialcomponentofmobiledevices,enablinguserstoconnecttheirdevicestothenetworkandaccessvariousservicessuchascalling,messaging,andinternetbrowsing.ThefirstSIMcardswerethesizeofcreditcardsandwerechallengingtohandle,makingtheminconvenientforusers.Toaddressthisissue,mini-SIMswereintroducedin1996,whichwere25%smallerthanthestandardSIMcards.
