No, the unlimited open access data cannot be shared. But with SMART Bro devices, they can connect on the device too!
Sharing your Rocket SIM unlidata via tethering / hotspot through SMART Bro Pocket WiFi, smart phones and non-locked wifi modems will still work. But for SMART Bro Home Wifi, it is recommended to use UNLIFAM 999 for the best data sharing experience.
