FlexiFone enables you to get a Multi-Network eSIM which would enable you to access EE, O2, Vodafone & Three's network in the UK. This means that you will always have the best network coverage across the UK. Best part about this is that you can keep your current or primary number, and use the FlexiFone eSIM for data. Your eSIM / SIM will automatically connect to the cellular network with the strongest signal, hence enabling you to have the best coverage even in the countryside, and dense city centers. We do offer Physical-SIMs as well, if you do not have an eSIM-enabled device. Getting started is simple, just download the app, select a plan, and setup your eSIM / Physical-SIM and you're good to go!

atreoLINK is self-hosting, for the whole family. It's the easiest way to share your home server's apps with the people you trust, and to reach them securely from anywhere. Run atreoAGENT on your home server or homelab, install atreoLINK on every family member's iPhone or iPad, and your self-hosted apps are a tap away. No port forwarding. No DNS setup. No VPN configuration. Just a custom subdomain with automatic HTTPS, a direct WireGuard tunnel, and encrypted push notifications. WHAT YOU CAN DO โ€ข Open your self-hosted apps from anywhere, in the built-in private browser โ€ข Receive end-to-end encrypted push notifications from your apps and services โ€ข Set up your server in minutes. Pair once, then it stays connected automatically โ€ข Invite family members and choose which apps each person can see โ€ข Manage your servers, devices, and invited users from one place DESIGNED FOR FAMILIES atreoLINK is built for households, not just sysadmins. As the owner, you approve every family member and pick what they can access. Invitations are cryptographically signed by you, so even atreoLINK itself can't add anyone to your household. PRIVACY BY DESIGN Your traffic flows directly between your phone and your server over WireGuard. atreoLINK helps the two sides find each other, but it never sees the bytes in between, never holds your passwords, and never has the keys to decrypt your notifications. Push notifications are encrypted on your server before they leave it, delivered as ciphertext, and decrypted only on your device. ACCOUNTS atreoLINK requires an account to sign in. You can create one to accept an invitation and connect your device to a family member's server. Learn more at atreolink.com. WireGuard is a registered trademark of Jason A. Donenfeld.
