Have you checked out Eskimo esim? They have coupons every so often on holidays for their worldwide esims. I believe they have one going for Chinese New Years that makes 30GB for $80. The data also has a 2 year expiration that rolls over on any global data purchase. Downside is their esims (mostly? all?) terminate in Singapore, so higher latency outside of the Asia region.
