eSIM with Private DNS Servers: Self-Hosted Privacy

Why Self-Host Your DNS?

While third-party encrypted DNS providers offer good privacy, self-hosting gives you complete control. No third party sees your queries and you set the retention policy. Combined with an anonymous eSIM from PrivateSims, a self-hosted DNS server maximizes your privacy chain.

Setting Up a Private DNS Server

• Pi-hole: Network-wide ad and tracker blocking with web interface
• AdGuard Home: Similar to Pi-hole with built-in DoH/DoT support
• Unbound: Lightweight recursive DNS resolver that queries root servers directly
• dnscrypt-proxy: Flexible DNS proxy supporting multiple encryption protocols

Connecting Your eSIM Device

Deploy your DNS server on a VPS in a privacy-friendly jurisdiction. Configure DoH or DoT so your mobile device can securely connect. Point your phone Private DNS setting to your server hostname. All DNS queries now go through your own server.
