For foreign buyers doing factory inspections in mainland China: the biggest frustration is losing WhatsApp and email connectivity the moment you cross the border. Here is the complete solution.
工廠驗貨現場的真實場景 / What happens at the factory
你在廣東工廠驗貨，需要即時把瑕疵照片WhatsApp發給香港辦公室的merchandiser確認。工廠WiFi打不開WhatsApp。你的漫遊SIM卡同樣受防火長城限制。中國同事的手機連上了，但你的外國號碼不行。
China eSIM：專為外籍採購設計
購買時提供你的護照國籍，eSIM寄出後在本國掃碼安裝（90秒），入境中國開漫遊，WhatsApp即時可用。整個驗貨行程全程網絡穩定，無論在廣州、義烏、寧波、青島的工廠。
