No, popular international calling apps like WhatsApp, FaceTime, and Instagram are generally blocked in mainland China due to the 'Great Firewall.' While TraveloeSIM provides reliable data connectivity, these specific applications require a Virtual Private Network (VPN) to function. We recommend installing a trusted VPN on your device before arriving in China if you intend to use these services. TraveloeSIM ensures your data connection is robust, but bypassing these blocks is dependent on your chosen VPN service.
