should i get airalo for a month in china?

i’m going to china in the summer and i’ve been using vpns+local sim but it’s really slow and i cant even load up some things.

i’m interested in trying an esim but idk if the local chinacom esim gets past the gfw or if it’ll keep my wechat functional

i’m nervous and i don’t want to waste money lol

eta: i do have a local sim and idk if there’s any way to use the local number with the esim data
