Adam Kos Abaningi bethu basenayo i-Nano SIM engokoqobo emafonini ethu, noma ama-iPhones esekele izinga le-eSIM iminyaka. Kungase kubonakale sengathi lesi isiphetho sokuthuthukiswa kwaleli khadi lokuhlonza obhalisile elisetshenziselwa ukuhlonza obhalisile kunethiwekhi yeselula, kodwa akunjalo. I-eSIM izongena esikhundleni se-iSIM.
Iyini inhloso ye-SIM, kungakhathalekile ukuthi ingeyomzimba noma ishumekiwe? Ikhadi le-SIM ngalinye linikezwa okufakiwe kurejista yasekhaya (i-HLR), equkethe ulwazi mayelana nobhalisile, izinsizakalo azivulile kanye nokushintshana kweselula okugcine kuqinisekisa ukuxhumana kwakhe nenethiwekhi. Ikhadi le-SIM lakudala lalihambisana nosayizi wekhadi lokukhokha, kodwa laqala ukuncipha ngokushesha, ikakhulukazi i-Mini SIM, i-Micro SIM futhi okwamanje kumaselula esimanje kuya ku-Nano SIM esakazeke kakhulu.
iPhone 14
I-iPhone XS ne-XR babe ngabokuqala ukuza ne-eSIM ngo-2018. Kusukela ngaleso sikhathi, wonke ama-iPhones aye ayisekela, kuhlanganise nesizukulwane sesibili se-iPhone SE. Ngakho ungaba nama-SIM amabili ku-iPhone yakho, eyodwa ngokomzimba neyodwa eSIM. Lokhu kuthatha indawo yekhadi le-SIM elihlukile elivamile, elakhelwe ngqo ocingweni, futhi idatha yokuhlonza ilayishwa kuyo ngesofthiwe.
Kungaba njalo okuthakaselayo
Kunezinzuzo ezimbili ikakhulukazi lapha, lapho ngokobuchwepheshe kungenzeka ukuthi inombolo yocingo eyodwa ilayishwe kuma-eSIM amaningi kanjalo namadivayisi amaningi. Umkhiqizi angabese eshintsha isikhala esigcinelwe i-SIM ephathekayo afake ezinye izingxenyekazi zekhompuyutha, kodwa ngisho ne-eSIM idinga inani elithile lesikhala. Kodwa-ke, inkinga ukuphatheka, lapho ungasusi i-eSIM ocingweni futhi uyifake kwenye. Ukuthi i-eSIM iwumkhuba wamanje kufakazelwa yiqiniso lokuthi i-Apple ayisanikezi i-iPhone 14 yayo ethengiswa e-US ngekhabethe elibonakalayo le-SIM ebonakalayo, eyathathelwa indawo yileli zinga.

I-iSIM iyikusasa
Abaningi sebeyamukele kakade i-eSIM njengesithasiselo se-SIM khadi yakudala noma bashintshele kuyo ngokuphelele, kodwa iqiniso liwukuthi ngisho nale SIM eshumekiwe izogcina ithole umlandeli wayo, okuzoba i-iSIM. Inzuzo yayo ukuthi iyi-SIM edidiyelwe. Ngakho-ke akuyona i-chip ehlukile, njengoba kunjalo nge-eSIM, kodwa ihlanganiswe ngokuqondile ku-chip processor. Ngaphezu kokudinga cishe indawo eyiziro, izophinde inikeze ukusebenza kahle kwamandla. Lokhu kudlala ngokusobala ezandleni ze-Apple, eklama ama-chips ayo futhi engakwazi ukuzuza ngokucacile kulesi sixazululo. Kodwa akayena umholi.
Ku-MWC23 e-Barcelona, i-Qualcomm imemezele ukuthi izovele ihlanganise i-iSIM kuma-Snapdragons ayo. Ngonyaka odlule, waze wabonisa inguqulo elungiswe ngokukhethekile ye-Samsung Galaxy Z Flip3, eyayivele ine-iSIM esebenzayo. Nakuba singaziswanga ngakho, i-iSIM isivele isekela i-chip yamanje yomkhiqizi, okungukuthi i-Snapdragon 8 Gen 2. Iphinde yathola isitifiketi se-GSMA salokhu futhi inikeza izinga elifanayo lokuphepha njenge-eSIM.
Kungaba njalo okuthakaselayo
U-Vratislav Holub Uma kuqhathaniswa ne-Nano SIM, enesilinganiso esingu-12,3 x 8,8 mm, i-iSIM incane ngokuphindwe ka-100. Ubukhulu bayo bungaphansi kwemilimitha yesikwele esisodwa. Futhi likude kangakanani ikusasa? Cishe isiyabonakala. Yize izinga belaziwa kusukela ngo-2021, iQualcomm ilindele ukuthi ngo-2027, ama-smartphones ayizigidi ezingama-300 analobu buchwepheshe azobe esedayisiwe. Akazange asho ukuthi wayebala ama-chips akhe kuphela noma awabancintisana nabo.
