※The current 5G network has around 90% population coverage rate, and the service coverage is still increasing in urban areas. In rural areas with limited 5G coverage, it is covered and supported by a 4G network.
※If your phone does not support 5G, you can still use our 5G Travel SIM, but you will only have access to 4G speeds. In this case, your phone must support band 1 and 18.
