ONEPHONE 1 ULTRA — The Smartphone for Second Life
Do NOT unlink the ONEPHONE HUD. Unlinking will break the HUD and it will stop working.
Do NOT edit the ONEPHONE HUD prims. Changing sizes, positions, or properties of prims manually may permanently break your HUD.
Only resize through Settings. Always use the HUD Size option in the Settings app to resize your phone. This is the only safe way to change the HUD size.
Do NOT rename the HUD or any part of it. Renaming the HUD or any of its prims will break your HUD.
Always update your HUD immediately when you receive an update. Updates are always free and will never delete your settings, contacts, messages, images, or any other content. All your data is stored safely on the server. Updating ensures your HUD has the latest security fixes, bug fixes, and improvements for the best possible experience.
Tip: Your phone number can be found in Settings → About ONEPHONE 1 ULTRA. Your email address is displayed in the Email app.
Your ONEPHONE HUD has three parts: the status bar (top), the screen (middle), and the home button bar (bottom).
You can position the phone differently for open and collapsed states:
The bottom bar of the HUD acts as the Home button. Clicking it will always take you back to the home screen.
Note: When viewing external websites or apps, the home button may take up to 3 seconds to respond due to Second Life limitations. Click once and wait — pressing multiple times may cause unnecessary reloads.
Inside the phone interface, each app has a back button (usually in the top-left corner) that takes you back instantly. You can also use the physical home button bar at any time.
Your home screen background can be customized in Settings → Wallpaper. Choose from included backgrounds or upload your own image (max 2MB, ideal size: 512 x 1024 pixels).
A customizable clock is displayed on the home screen. You can change:
All clock options are in Settings → Clock Widget.
The dock at the bottom of the home screen provides quick access to up to 3 apps of your choice.
Tap the app drawer icon to see all your installed apps. You can also long-press in the app drawer to enter edit mode, where you can quickly remove optional apps.
Notifications appear on the home screen and are color-coded by type (e.g., orange for alarms, blue for messages, red for missed calls). You can dismiss them individually or use Clear All to remove them at once.
A small tab on the right edge of the screen opens the Quick Access sidebar when tapped. It provides four shortcuts:
Note: Mute only silences sounds — you will still receive visual notifications. Airplane mode only blocks incoming calls — messages and emails are not affected.
Every ONEPHONE user receives a unique 8-digit phone number. Share this number with others to connect.
You can view incoming and sent (pending) contact requests in the Contacts app. You can accept or reject incoming requests.
You can block a user from their contact detail page, or manage blocked users in Settings → Blocked Users. Blocked users cannot send you messages or call you.
You can set a custom profile image for yourself in My Card (visible to your contacts), and you can upload custom images for individual contacts to personalize your contact list.
Send and receive text messages with your connected contacts.
Free plan limit: 120 sent messages per month. Receiving messages is always unlimited. Upgrade to ONE Telecom Pro for unlimited messaging.
Call your connected contacts to let them know you want to talk.
Note: Due to Second Life HUD limitations, actual voice calling is not yet available. The call feature works as a realistic simulation to signal someone you'd like to speak with them.
Every ONEPHONE user gets an email address in the format yourname@ONESL.inworld.
Important: ONEPHONE email is an internal system only. You cannot send to or receive from real-world email addresses (Gmail, Outlook, etc.). It works exclusively between ONEPHONE users.
Free plan limit: 120 sent emails per month. Receiving emails is always unlimited. Upgrade to ONE Telecom Pro for unlimited email.
ONE Telecom system accounts (such as noreply@ONESL.inworld and support@ONESL.inworld) may send you important information and updates.
Plan and organize your schedule with the Calendar app.
The Clock app includes four features:
Displays the current time in your selected timezone.
Set a countdown timer. When it reaches zero, an alarm will sound.
A simple stopwatch with start, stop, and reset controls.
Upload, manage, and share images directly from your computer.
Note: If your gallery is full (100 images), you must delete some photos before you can accept new shared images.
A simple note-taking app for quick text notes.
A calculator app for quick calculations in-world. Your last 5 calculations are saved in the history.
Navigate Second Life locations with the Maps app.
Check real-world weather conditions from inside Second Life.
Browse the web from inside your ONEPHONE.

Safely resize your phone HUD from 50% to 150%. This is the only safe way to change the HUD size — never resize manually through Edit mode.

With an active ONE Telecom Pro subscription, you can access your ONEPHONE from any web browser.
After logging in, your browser may prompt you to install ONEPHONE as an app. This adds it to your phone's home screen, tablet, or desktop as a standalone application — giving you a native app experience with no browser chrome.
When on an external website, the home button may take up to 3 seconds. This is a Second Life limitation. Press once and wait — do not press repeatedly.
Set your open and collapsed positions as described in HUD Basics. Both positions are saved automatically.
