The Game Changer

🇨🇳 China — Why This Is Not a Close Call

China blocks Google, Instagram, WhatsApp and YouTube. A local Chinese SIM is subject to the exact same blocks. Airalo uses local Chinese carrier data in China — blocked, just like locals.

Holafly routes through international carriers. Your phone thinks it’s roaming — the Great Firewall doesn’t apply to roaming connections. I tested this in Shanghai and Beijing. Google Maps worked. Instagram worked. WhatsApp worked. YouTube worked. No VPN, no setup.
