Adam Kos Uma usenefoni ye-3G engasekeli amanethiwekhi esizukulwane esisha (okungukuthi i-4G noma i-5G), ngeke ukwazi ukusebenzisa idatha yeselula kahle ngayo ekupheleni kwalo nyaka. Phakathi no-2021, yonke i-troika yabaqhubi basekhaya izocisha ngokuphelele le nethiwekhi, ngokusho kwabo isivele isindile. Lokhu kuzovumela inethiwekhi yesizukulwane sesi-5. Izodala imibimbi ikakhulukazi kulabo abasasebenzisa i-iPhone 4 ne-4S.
Kungaba njalo okuthakaselayo
I-Vodafone yacisha i-3G kakade ngoMashi, i-O2 okwamanje ihlose ukwenza kanjalo ngoMeyi, i-T-Mobile ayihlele ukwenza kanjalo kuze kube uNovemba. Inethiwekhi yesizukulwane sesithathu ineminyaka engu-3 ubudala futhi ingena emhlalaphansi owufanele. Ilethe idatha yeselula eshesha ngempela ngesikhathi sayo futhi sonke sikukweleta ukukhula kobuchwepheshe beselula. Bekubaluleke kakhulu ukuthi abakhiqizi baqambe amafoni abo ngayo, bona i-iPhone 12G/3GS. Ngakho-ke uma ungumnikazi we-iPhone 3G eshiwo ngenhla, i-3GS noma i-iPhone 3 noma i-4S, ekupheleni konyaka ngeke usakwazi ukusebenzisa idatha yeselula “esheshayo” nayo ngisho nakunethiwekhi ye-T-Mobile. I-iPhone yesizukulwane sokuqala yayingenayo inethiwekhi ye-4G, ama-iPhones 3 futhi kamuva ayevele ekwazi ukwenza isizukulwane sesine. Kodwa-ke, mayelana nokuxhumeka kwe-Wi-Fi, ukuthumela imiyalezo noma ukushayela, vele akukho okushintshile. Kumele kuqashelwe ukuthi i-Apple yayeka ukweseka lezi zingcingo kudala.
I-iPhone 4(S):
Igalari yezithombe
Hhayi kuphela i-iPhone, kodwa futhi nabanye abakhiqizi
Ama-iPhone ashiwo akuwona wodwa ongasakwazi ukusefa ngawo ngaphandle kwe-Wi-Fi. Izophinde ithinte amafoni avela ku-Samsung, Huawei, Honor, Xiaomi, HTC nabanye. Isibonelo, i-T-Mobile kuwebhusayithi yabo ibala uhlu olubanzi lwamadivayisi elisabhalisa kunethiwekhi yayo futhi abanikazi bazo kuzodingeka bashintshele emshinini omusha. Nakuba endabeni ye-Apple "i-cut-off" ye-iPhone 4S, eyethulwa ngo-Okthoba 2011, amafoni avela kwabanye abakhiqizi ngaphandle kokusekelwa kwe-4G akhiqizwa muva nje, ngo-2018.
Ukwenziwa kwesimanje akukwazi ukugwenywa. Amafrikhwensi lapho inethiwekhi ye-3G esebenza khona manje azosetshenziswa kumanethiwekhi e-4G ne-5G asebenza kahle kakhulu. Futhi amanethiwekhi e-5G yilokho esikufuna kakhulu manje. Kuyafana njengoba kwakunjalo nge-3G. Yize amafoni ayesevele ekhona, inethiwekhi yakhula kancane ngempela. Kuyiqiniso, nokho, ukuthi uguquko olusuka ku-EDGE ngaleso sikhathi lwalulukhulu kakhulu. Nge-4G/LTE yanamuhla, ngokuqinisekile sizohlala isikhashana. Nakuba, uma ungazi, i-6G isivele ihlelelwe ukuthi iqale ukuhlolwa e-China kulo nyaka. Lokhu kufanele kusheshe ku-50x kune-5G futhi abakwaSamsung bangathanda ukuyethula ngo-2028.
