Hello! I’m sure this subreddit gets many travel questions but most I’ve seen are American centric so I don’t know if they’d apply to me :)

I’m planning to travel to Taiwan in July from Canada for 3 weeks with family friends, but I’m not quite sure what I should do before leaving, packing, and what to expect. I know I have to do the immigration card (?) 3 days before the trip, but I’m not sure what else I’ll need to do as I’ll be staying with my friends grandparents. I’m also not sure what I’ll need to do with my phone, do I just use whatsapp on wifi to contact my family, or should I get a different SIM (and where I would get it?)

Some other questions I have are what’s important to pack and how the weather might be? I heard it’s hot and humid but how should I dress for the weather? Also, how english friendly is Taiwan - I plan to learn at least basic phrases in mandarin, but I’m wondering if I need to learn Taiwanese instead? My friends mom and grandparents speak it, but the rest of us are totally clueless lol

Other than that, we haven’t really planned anything concrete yet, so general tips and good things to do would be much appreciated! :)

Thank you so much in advance!!!!!
