Received the 3 DIY ($270 365 days) yesterday. It works in TP-LINK M7650 WiFi egg and the reception is very stable . Although Duck SIM has faster transfer rate (when it works), it always load "空氣"
918MB is the data usage (not speed) . Previously the fastest DL speed of Duck SIM with M7650 was 110Mbps. Would test the 3 DIY at various locations. Anyway, the theoretical max. DL speed of M7650 (Cat 11) is 600 Mbps.
