1. Important Warnings

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.

2. Getting Started

Attaching the HUD

  1. Locate the ONEPHONE 1 ULTRA HUD (Add me) in your Second Life inventory.
  2. Right-click it and select "Add" or "Attach to HUD" → Center (or Center 2).
  3. The HUD will appear on your screen and begin its startup sequence.

First-Time Setup

  1. The phone will boot up with an animated startup screen.
  2. Your avatar UUID is automatically registered with the server.
  3. You will be prompted to enter your display name - this is the name other ONEPHONE users will see.
  4. Click Continue to complete the setup.
  5. Your ONEPHONE is now ready to use. You will receive an 8-digit phone number automatically and can choose your own email address (yourname@ONESL.inworld).

Tip: Your phone number can be found in Settings → About ONEPHONE 1 ULTRA. Your email address is displayed in the Email app.

3. HUD Basics

Opening & Collapsing the Phone

Your ONEPHONE HUD has three parts: the status bar (top), the screen (middle), and the home button bar (bottom).

Setting Your Preferred Position

You can position the phone differently for open and collapsed states:

  1. With the phone open, right-click it and select Edit, then move it to your preferred open position.
  2. Collapse the phone by clicking the status bar.
  3. Move the collapsed phone to your preferred collapsed position.
  4. Both positions are saved automatically. The phone will return to the correct position each time you open or collapse it.

Home Button

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.

Navigation

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.

4. Home Screen

Wallpaper

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).

Clock Widget

A customizable clock is displayed on the home screen. You can change:

All clock options are in Settings → Clock Widget.

App Dock

The dock at the bottom of the home screen provides quick access to up to 3 apps of your choice.

App Drawer

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

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.

5. Quick Access Sidebar

A small tab on the right edge of the screen opens the Quick Access sidebar when tapped. It provides five shortcuts:

Note: Mute only silences sounds - you will still receive visual notifications. Airplane mode only blocks incoming calls - messages and emails are not affected.

6. Contacts

Every ONEPHONE user receives a unique 8-digit phone number. Share this number with others to connect.

Adding a Contact

  1. Open the Contacts app.
  2. Tap the Add Contact button.
  3. Enter the other person's 8-digit phone number.
  4. A contact request is sent to them. They must accept before you can communicate.

Managing Requests

You can view incoming and sent (pending) contact requests in the Contacts app. You can accept or reject incoming requests.

Blocking

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.

Contact Avatars

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.

Group Chats

Free plan limit: 120 sent messages per month (including group messages). Receiving messages is always unlimited. Upgrade to ONE Telecom Pro for unlimited messaging.

8. Phone (Calling)

Call your connected contacts directly from your phone.

Voice Calls (Web & PWA)

When both you and the person you're calling are using ONEPHONE through the web browser or PWA, your call becomes a real voice call using your device's microphone.

Note: Voice calls are only available when both users are on the web/PWA version. When using the phone through the Second Life HUD, calls function as a call signal - the receiver's phone rings, and they can accept or decline, but no voice audio is transmitted due to SL HUD limitations.

9. Email

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.

  2. Select your preferred plan duration (1, 3, 6, or 12 months).

Gift Subscriptions

You can buy a ONE Telecom Pro plan for any other avatar straight from the in-world ONE Telecom Terminal:

  1. Touch the terminal and choose Gift Subscription.
  2. Enter the recipient's avatar name. The terminal looks them up natively in Second Life - no UUID needed.

  5. Pay the L$ amount. Both you and the recipient get a confirmation receipt in IM, and the recipient's plan activates instantly.

Gift activations do not enable auto-pay on the recipient's account - they keep full control of how their plan renews after the gifted period ends.

30. Web & PWA Access

With an active ONE Telecom Pro subscription, you can access your ONEPHONE from any web browser.

Logging In

  1. Visit ONESL.world from any device.
  2. Click "Subscriber Login".
  3. Enter your avatar UUID and your 8-digit web login code (found in Settings → ONE Telecom).
  4. Your phone interface loads in the browser, fully functional.

Install as App (PWA)

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.

Web Voice Calls

When both you and your contact are using ONEPHONE via the web or PWA, calls become real voice calls. Your browser's microphone captures your voice and transmits it directly to the other person - no third-party services required. You can mute/unmute during the call. See Phone (Calling) for full details.

31. Troubleshooting

An app crashed - using the Bug Reporter

If any app on ONEPHONE hits an unexpected error, the phone now shows a recovery screen instead of a blank page. From there you can:

Phone won't load or shows a blank screen

No sounds playing

Can't receive calls

Voice call has no audio

Home button takes too long

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.

HUD position resets

Set your open and collapsed positions as described in HUD Basics. Both positions are saved automatically.

ONELIGHT bulb not showing in Add Device
