DNSSEC vs eSIMTools

DNSSEC routes your device's DNS queries through a DNSSEC-validating resolver — in one tap, without a VPN. Modern DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT) encrypt your queries in transit. DNSSEC validation at the resolver ensures the answers haven't been tampered with. Together they make DNS the private, trustworthy channel it was always meant to be. BUILT-IN DNS4EU PRESETS DNS4EU is the European Commission-backed public resolver network. Four presets ship with the app: • Protective — blocks malware and phishing domains • Protective + Ad Blocking — adds tracker and ad filtering on top • Protective + Child Protection — adds adult content filtering • Unfiltered — encrypted and DNSSEC-validating, no content filtering Pick a preset and tap Apply. iOS will prompt you once to allow the DNS profile, then it's active system-wide. YOUR OWN RESOLVER Prefer a different provider? Add any DoH or DoT endpoint: • Enter a DoH URL (https://…) or a DoT hostname • Optionally add fallback IP addresses for bootstrapping • Flag it as DNSSEC-validating to track which resolvers you trust Custom resolvers are stored on-device and never leave it. ONE TAP, SYSTEM-WIDE The profile installs via the operating system's built-in DNS Settings — no VPN tunnel, no proxy, no configuration profile to trust manually. Once applied, every app on your device uses the configured resolver. Remove it any time from within the app or from Settings › General › VPN & Device Management › DNS. WORKS EVERYWHERE Available for iPhone, iPad, Mac, Apple TV, and Apple Vision Pro.

eSIMTools is an eSIM-to-SIM toolkit for working with supported programmable eUICC and SIM modules. It helps developers, testers, integrators, and connectivity teams read card information, inspect installed profiles, and manage the path from an eSIM activation code to a writable SIM-style module. Use eSIMTools to read EID and eUICC details, view installed profiles, scan or manually enter eSIM activation codes, download carrier profiles, and write compatible profiles to supported eUICC cards. The app is designed for controlled eSIM provisioning workflows where visibility, repeatability, and clear reader status matter. Key capabilities: - Read eUICC card information and EID - View installed profiles and profile status - Scan QR activation codes or enter activation codes manually - Download carrier profiles through the LPA workflow - Write profiles to supported eUICC/SIM modules - Connect through compatible USB CCID readers - Connect to supported Bluetooth eSIM modules - Review storage and profile diagnostics before installation - Manage installed profiles from a clear profile console eSIMTools focuses on practical eSIM-to-SIM testing and provisioning. It is not a carrier service and does not provide mobile plans. Profile download and installation require a valid activation code, network access, and compatible reader or module hardware.
