Hi, less than 48 hours ago you had a "Show HN".
Your claim "we don't learn which eSIM your phone gets" is false. The eSIM update protocol, which is implemented in firmware which you do not control, will send you (the carrier) the eSIM's permanent ID (the EID), and you can't stop this. https://news.ycombinator.com/item?id=32416373 https://news.ycombinator.com/item?id=32416373
Moreover, you provide no protection whatsoever against IMEI tracking, which all carriers implement. IMEIs are reported to the carrier immediately after authentication/attach (AKA), and many will block invalid/unexpected IMEIs. You can't prevent this. Without a solution to IMEI tracking your work on IMSI tracking isn't much use. This won't protect anybody from the telcos. At best it might stop people using a stingray without assistance from the telco (i.e. almost nobody). https://news.ycombinator.com/item?id=32416308 https://news.ycombinator.com/item?id=32416308
