› WHY AN eSIM
Why an eSIM for China
China is OUTSIDE the European Union. Home-plan roaming there is expensive (often €8-13/MB or even blocked). An Alosea eSIM = a few euros to stay connected throughout. Your home number stays active for banking SMS (essential: your bank will likely send multiple verification SMS during your stay). Installation in 2 min via QR. China is the world leader in 5G deployment since 2019 (over 3.4M 5G base stations — more than the rest of the world combined). On arrival at Beijing (PEK / PKX Daxing), Shanghai (PVG / SHA), Guangzhou (CAN) or Chengdu (CTU), you can buy a China Mobile / China Unicom / China Telecom physical SIM, but expect to pay around €10 just for the SIM card itself (passport required for mandatory ID registration in the traveller's name — 20-40 min process at the counter) — on top of the data plan. IMPORTANT POINT — THE GREAT FIREWALL: China has blocked since 2003 (Golden Shield Project 金盾) all Google services (Search, Maps, Gmail, YouTube, Drive, Photos), Meta (Facebook, Instagram, WhatsApp, Messenger), X/Twitter, the New York Times, the BBC, and many Western sites. HOWEVER, an Alosea travel eSIM in China routes via a foreign network (international roaming partner, foreign IMSI technology) — most VPN-blocked services therefore typically work WITHOUT a VPN, because you use a foreign IP and your traffic transits through the roaming partner's servers outside China. Honestly: this is NOT GUARANTEED 100 %, it depends on the roaming partner operator routing and the host Chinese operator's policy at the moment — some travellers report everything works perfectly (Google Maps, WhatsApp, Instagram), others report intermittent cuts. Comparison: a local Chinese SIM (China Mobile / Unicom / Telecom) is SUBJECT to the Great Firewall by construction and absolutely requires a VPN for Google/WhatsApp/Instagram (VPN to install BEFORE arriving in China, because VPN websites are blocked from China). And concretely on arrival at Beijing (PEK / PKX Daxing), Shanghai (PVG / SHA Hongqiao), Guangzhou (CAN) or Chengdu (CTU)? You can buy a China Mobile, China Unicom or China Telecom physical SIM at the airport counter, but expect to pay around €10 just for the SIM card itself (passport required for mandatory ID registration, 20-40 min process) — on top of the data plan. With an Alosea eSIM activated BEFORE boarding, you walk off the plane already connected for Didi, Baidu Maps or WhatsApp. IMPORTANT TO UNDERSTAND: an Alosea travel eSIM in China routes via a foreign network (international roaming partner), so most services blocked by the Great Firewall (Google, WhatsApp, Instagram, Facebook, YouTube, X/Twitter) typically work WITHOUT a VPN — but this is NOT GUARANTEED and depends on the roaming operator routing, which can vary. A local Chinese SIM is SUBJECT to the Great Firewall and requires a VPN.
