Saily covers both: Hong Kong plans start at $3.99 and mainland China plans at $4.49 for 1 GB. Visiting both? Add one plan per destination to the same Saily eSIM.
The catch: plans are data only, so you get no local phone number for calls or texts.
A trip that combines Hong Kong and mainland China means two destinations with separate plans. With Saily you keep one eSIM on your phone and add a plan for each place, so you don’t swap SIM cards at the border.
