Users have reported mixed experiences with this product. Many found it convenient and reliable, especially for accessing unrestricted internet services like Google, Facebook, and WhatsApp. The plug-and-go feature, requiring no activation or registration, was praised for its simplicity.

However, some users faced issues with the SIM card not working as expected. A few reported connectivity problems after a couple of days, while others found the included pin tool ineffective for opening SIM card trays. Despite these issues, many users appreciated the clear instructions and the ability to use data seamlessly throughout their stay.

Overall, this SIM card is a good option for short-term travelers needing reliable internet access in China and Macau. However, potential buyers should be aware of possible connectivity issues and ensure their devices are unlocked before use.
