My experience with esims is fantastic. I loaded 5 of them on my phone (bought cheap plans with low data tiers) and switch them accordingly. High speed, no censorship at all, decent lag to western sites, I’m not detected as a VPN user.

Arrived in the airport, toggled, worked.

Physical SIM… Didn’t try this year but even 6 years ago it was extremely problematic to get one as a foreigner, no store would accept my form of identification, I was offline for three days until I caved in and finally paid 200 yuan extra for a preactivated one (on someone else’s id , I guess) on the grey market. And then there’s the problem that even if the plans are cheap (I’m seeing $1/month for 5gb), it’s rendered useless by the gfw. What’s the point of having 200 Mbits of 5g bandwidth if any website that you can think of (including hexbear and .ml surprisingly, I wouldn’t expect that they would block tankies), is banned? Better using a HK esim at 30mbits in 4g but with the full internet unlocked…

VPNs it’s a cat and mouse game that I don’t want to play anymore. You never know if the website isn’t loading because the VPN has been blocked, or the website blocked the VPN, or it’s a temporary connection issue, or today the server is overloaded…
