I've been instructed from afar to procure a wifi egg (for use while in quarantine both in HK and overseas).
When I spoke to the saleslady at Fortress:
1. she told me that the ones which do not require a sim card will not be good enough to stream Netflix etc and if I want to be able to watch movies, I need one which takes a sim card
2. when I asked whether I could use the one in my phone, she started talking about "plans" and I didn't get a clear answer (as much my fault as hers as I was in a hurry).
Any thoughts on what is the best option?
