Show HN: WalledGarden – A SIM You Control (RBI/GeoAuth/VPN/NGFW/Socks/Pcap/SDX)

Hello HN, somewhat foolishly I've followed the same line of reasoning as Ray Kinsella and built it (thankfully not in a field, although maybe it could pass as a "SIM of (only my?) Dreams"?)...

walledgarden.ai's P (data SIM card) - of the fabled MVP - seeks MF for PMF; the SIM (eSIM is on the roadmap, subject to demand) features:

SIM Isolation/RBI - restrict access from the SIM to Remote Browser Isolation services (e.g. Hyperbeam[0]), limiting the number of routes for data to leave the device/phone. This can also be expanded to cover other services - allow only Hyperbeam[0]+Beeper[1]+VoIP for RBI web browsing+messaging+calls, RethinkDNS[2] & Orbot[3], WireGuard, etc.

GeoAuth - IMEI, ICCID and/or Location attestation, that can be used for network control of SIM traffic (e.g. automatic blocking of banking and/or bitcoin app connectivity when outside, or inside, of your defined geofence(s)).

VPN (VN) - "clientless VPN" tunneling. Route traffic via WireGuard or Tailscale, without requiring a VPN client/Tailscale on the device.

Firewalls - opt to route your SIM's traffic through multiple vendors' Enterprise/"Next Generation"/<insert network-security-buzzword(s) here> Firewalls, to facilitate threat-intel-based blocking.

SOCKS/Tor - enable clientless/transparent proxying of TCP traffic via SOCKS or Tor.

Pcap - enable packet capture/visibility & analysis of all traffic sent via the SIM's data connection; trust but verify your device's/phone's OS and/or app connectivity (e.g. DNS traffic can leak outside the VPN tunnel on Android[4], iOS VPN leak[5], etc).

SocialsDetox[6] - network-based blocking of Social Media (+others).

It is a data-only SIM card, so no traditional voice/VoLTE connectivity (albeit VoIP will work), offering roaming connectivity in over 90 countries.

The signup process is currently high friction (CC+ACH/BACS/SEPA, shipping a physical SIM, etc), the data rates are not intended to be cost-competitive with existing "dumb" carriers, and such an offering will not appeal to everybody.

Quite simply the product is functional and I'm now seeking patient early adopters, prepared to wait for a SIM in the mail, who can see enough value in their use case(s) to vote with their wallets and signup. Hopefully those same early adopters will be willing and active participants in the walledgarden.ai community, to provide feedback and vote for new features/use cases (all suggestions are welcome).

PS: aTdHvAaNnKcSe for reading, it has been somewhat of a trial just to get this far with the product; oh the joys of (cellular networks|Machines|industry changes)!.
