Network-Level Encryption Techniques for eSIM Users

Beyond Basic Encryption

While eSIM profiles and cellular connections provide baseline encryption, privacy-conscious users need additional network-level encryption. PrivateSims recommends layering these techniques on top of your anonymous eSIM connection for comprehensive privacy.

VPN Protocols Compared

• WireGuard: Modern, fast, and secure with minimal codebase
• OpenVPN: Battle-tested with extensive audit history but slower
• IKEv2/IPsec: Good for mobile due to seamless reconnection when switching networks

DNS Encryption

DNS queries reveal which websites you visit. Use DNS-over-HTTPS (DoH) or DNS-over-TLS (DoT) to encrypt all DNS queries. Recommended providers include Quad9, Cloudflare, or self-hosted DNS resolvers.

Traffic Obfuscation

In countries that block VPN traffic, obfuscation techniques disguise VPN traffic as regular HTTPS traffic. Tools like Shadowsocks, V2Ray, and obfs4 help your VPN traffic pass through deep packet inspection systems undetected.
