In our quest to stay connected during our travels, we recently tested the China Data only SIM card designed for 15 days of use in Mainland China and Macau. With 5GB of high-speed 5G/4G internet data, we were eager to see how well it performed in such a digital landscape. Right off the bat, the free test data in the US offered a smooth introduction, letting us connect before our trip even began. Once in China, we appreciated the unrestricted internet access that allowed us to use popular platforms like Google, Facebook, WhatsApp, and Instagram without a hitch. This flexibility was invaluable for keeping in touch with friends and sharing our experiences. Overall, we found the SIM card to be a reliable companion for our adventures, offering great value and peace of mind as we explored the vibrant culture of China.
