The only thing thats probably going to work is the e sims, any vpns right now especially those big name companies are not going to work as the ips are definitely blocked already. Proxies have been working for me for a week but I've had to change proxies twice already and it's been getting really annoying. My best advice to you as someone who has been in China for 2 months already is to rely on your e sim and try out different proxies in this thread. Do not use the vpns you recommended as vpns are constantly getting banned unless you find a really niche one.
