Yes, absolutely! We do not restrict you from sharing your data bundle with your family and friends, just simply switch on your tethering/ portable hotspot function on your phone to start sharing.
My iPhone is not on iOS11 yet, can I use personal hotspot/tethering function on MyRepublic network?
No. You have to upgrade your current OS to the latest version (at least iOS11 and above) to use this function on MyRepublic network.
