Adam Kos Ngati mudakali ndi foni ya 3G yomwe sigwirizana ndi maukonde amibadwo yatsopano (i.e. 4G kapena 5G), simudzatha kugwiritsa ntchito bwino deta yam'manja nayo kumapeto kwa chaka chino. M'chaka cha 2021, gulu lonse la ogwira ntchito zapakhomo lidzazimitsatu maukondewa, omwe malinga ndi iwo adapulumuka kale. Izi zipereka njira ku network ya 5th generation. Idzayambitsa makwinya makamaka kwa omwe amagwiritsabe ntchito iPhone 4 ndi 4S.
Izo zikhoza kukhala chidwi inu
Vodafone yazimitsa 3G kale mu Marichi, O2 ikufuna kutero mu Meyi, T-Mobile sikukonzekera kutero mpaka Novembala. Ma network a 3rd ali ndi zaka 12 ndipo akulowa pantchito yoyenera. Zinabweretsa zambiri zam'manja zothamanga kwambiri panthawi yake ndipo tonsefe tili ndi ngongole chifukwa chaukadaulo waukadaulo wam'manja. Zinali zofunika kwambiri kuti opanga adatcha mafoni awo pambuyo pake, onani iPhone 3G/3GS. Chifukwa chake ngati muli ndi iPhone 3G, 3GS kapena iPhone 4 kapena 4S zomwe zatchulidwa, pakutha kwa chaka simudzatha kugwiritsanso ntchito "mwachangu" data yam'manja nayo ngakhale mu netiweki ya T-Mobile. M'badwo woyamba wa iPhone unalibe netiweki ya 3G, ma iPhones 5 ndipo kenako anali okhoza kale m'badwo wachinayi. Komabe, ponena za kugwirizana kwa Wi-Fi, kutumizirana mameseji kapena kuyimba foni, ndithudi palibe chomwe chimasintha. Tiyenera kudziwa kuti Apple idasiya kuthandizira mafoniwa kalekale.
