Second Life Voice on Your Phone: How It Works in 2026

Yes, you can use Second Life voice on your phone in 2026, and there are three routes to it: Linden Lab's official Second Life Mobile app, which has been testing voice; the Speedlight app for Android and iOS, which added WebRTC voice in October 2025; and a browser client such as Thunder Viewer, which runs spatial voice in Safari or Chrome with nothing to install. If you landed here from a forum thread saying no mobile client supports voice, that thread is from 2015, and the grid has changed underneath it.

This guide compares those three routes fairly, walks through setting up voice in a phone browser on iPhone and Android, explains what spatial voice actually does to what you hear, and covers the reasons a voice session goes silent. For the wider picture of chat, IMs and the 3D view on a phone, start with our overview of every way to run Second Life on mobile.

The short answer

Second Life voice now runs on WebRTC across the grid, the same real-time audio standard that powers calls in every modern browser and phone. That single change is why "Second Life voice chat mobile" went from impossible to ordinary. The old voice system needed a separate voice client next to the desktop viewer; WebRTC is already built into your phone. Our explainer on Second Life's move to WebRTC voice covers the infrastructure side.

So the real question is no longer whether you can talk from a phone, but which route fits how you use Second Life.

Three ways to use Second Life voice on your phone

The official Second Life Mobile app

Linden Lab's own app is on the App Store and Google Play and renders the 3D world on your phone. Linden Lab has been testing experimental WebRTC voice in its mobile beta. Its 2026 release notes so far have focused on other areas (object chat and bubble chat in February, a new-user chatbot and a Portuguese interface in March), so check the latest app notes in your store listing for where voice stands today. Our review of the official app tracks its beta updates in more detail.

Best for: residents who want the official experience and the 3D world in their hand.

Speedlight

Speedlight is an established Second Life client with a real 3D view and apps for both Android and iOS. Its Google Play listing, at its October 2025 update, says it supports Second Life WebRTC voice for real-time spatial voice chat. At that update the listing said WebRTC was available in selected regions: the official WebRTC test regions, Builders Brewery, and official meeting regions. Coverage may have grown since, so check the listing or speedlight.io for current details.

Best for: residents who want a full-featured mobile app with a 3D view and voice in one install.

A browser client (Thunder Viewer)

Thunder Viewer is a chat-first Second Life client that runs in your phone's browser. Spatial voice runs over WebRTC directly in the browser tab, using Second Life's own voice infrastructure, so there is no app and no plugin. You get local voice with the people around your avatar, alongside IMs, local chat, friends, teleports and a mini-map.

Best for: residents who want voice and chat from any phone without installing anything, or who already use a browser client on a laptop.

Side by side

You can keep more than one of these on your phone. Just remember Second Life allows one active login per avatar, which matters for voice in a way we cover in troubleshooting below.

How to set up Second Life voice in your phone browser

These steps use the exact labels you will see in Thunder Viewer. The flow is the same on iPhone (Safari or Chrome) and Android (Chrome).

1. Sign in and close other viewers

Go to thunderviewer.com/login on your phone and sign in with your Second Life username and password, plus your authenticator code if your account uses two-factor authentication. Before you do, sign that avatar out of Firestorm, the official app, or any other viewer. Our step-by-step guide to playing Second Life from your phone covers sign-in in detail.

2. Put on headphones

Use earbuds or headphones, wired or Bluetooth. The browser applies echo cancellation and noise suppression to your microphone, but a phone speaker sitting a few centimetres from the phone's mic is the hardest case for any echo canceller. Headphones also keep the stereo panning intact, which is the whole point of spatial voice.

3. Open Local Chat

Tap Chats in the bottom bar, then the Chats segment at the top. Local Chat is pinned at the top of the list with the name of your region. Tap it.

4. Tap Join

In the Local Chat header, tap Join. While it connects, the button shows a short ellipsis.

5. Allow the microphone

The first time, your browser asks for permission to use your microphone. Tap Allow. On iPhone, Safari asks per site; on Android, Chrome shows the prompt at the top or bottom of the screen.

6. Talk, mute, leave

Once connected, Join becomes Leave and a microphone button appears next to it. Your mic is live as soon as you join, so tap the microphone to mute (the icon gets a slash) and tap again to unmute. Tap Leave when you are done.

If you see an Enable audio button, tap it. Phone browsers sometimes block audio from playing until you touch the page, and that button hands the browser the tap it is waiting for.

7. Teleport freely

When you teleport to another region, local voice reconnects on its own for the new region. You do not need to tap Join again.

What "spatial" means for your ears

Second Life voice is not a group call where everyone sounds the same. The voice server mixes one stream for your ears, built around where your avatar is standing. Voices to your avatar's left come from the left, voices nearby are louder, and people far away fade out, past roughly 50 metres.

Here is a detail from building voice in a browser that explains a lot of first-session confusion: the voice server sends you nothing until it knows where your avatar is. Your client has to report your position first, and only then does the mix start flowing. That is why voice starts a moment after you join rather than instantly, and why a brief silence right after Join is normal.

The practical rule: if someone sounds faint, move closer. On a phone, open Nearby, switch to Map, and double-tap a spot near the speakers to walk your avatar over.

Why you can't hear anyone: troubleshooting silence

Work through these in order. Most silent sessions are one of the first three.

Microphone permission was denied. If you tapped Block or Don't Allow, the microphone button shows a crossed-out circle with the tooltip "Microphone permission denied". Fix it in your browser's site settings: on iPhone, tap the page settings in Safari's address bar (or Settings, then Safari, then Microphone); on Android, tap the icon left of the address in Chrome, then Permissions. Then leave and join again.

The place has voice turned off. Parcel and estate owners can disable voice in their area, and plenty do, for clubs that stream music or quiet stores. When voice is not offered where you are, the button reads Voice off instead of Join. That is the place, not your phone. Teleport somewhere voice is on.

You are too far away. Because the mix is built around your avatar's position, a crowd on the other side of a large region is out of earshot. Move closer on the Map.

Another viewer signed in as the same avatar. Second Life allows one active session per avatar. If Firestorm or the official app on another device logs in as you, it boots your phone session, voice included. If that viewer reconnects automatically, the two can keep knocking each other off. We have watched this ping-pong in our own logs, which is why Thunder Viewer steps aside when it detects you signed in elsewhere instead of logging back in. Close the other viewer, or use a different avatar on each device.

Nobody is talking. It happens. A quiet region is quiet on desktop too.

Where to find people to talk to

Voice works best where people go to talk. Linden Lab keeps an official list of Voice Chat Hot Spots in the Destination Guide: social hangouts and lounges where voice is the point. Paste any of those SLURLs into the teleport field at the top of Chats or Nearby, tap Join in Local Chat once you arrive, and listen for a minute before you speak, the same etiquette as walking into any room.

Not sure there is anyone left to talk to? Our look at whether Second Life is still active has the current numbers, and if you are new to the grid entirely, what Second Life is explains regions, SLURLs and the rest of the vocabulary.

FAQ

Can I play Second Life on my phone?

Yes. The official Second Life Mobile app for iOS and Android shows the 3D world, Speedlight offers apps with a 3D view, and browser clients like Thunder Viewer give you chat, IMs, teleports and voice in a phone browser with nothing to install. Our Second Life on mobile overview compares them.

Is there a mobile app for Second Life?

Yes. Linden Lab's official Second Life Mobile app is on the App Store and Google Play, and it is still in beta with regular updates. Install it only from those stores.

Can I use Second Life voice chat on mobile?

Yes. Second Life voice runs on WebRTC across the grid, so phones can join it. Speedlight's listing says it supports WebRTC voice, Linden Lab has been testing voice in its app, and Thunder Viewer runs spatial voice in your phone browser.

Do I need headphones?

Strongly recommended. Echo cancellation helps, but a phone's speaker and mic sit very close together, and without headphones the people near you may hear themselves echo back. Headphones also let you hear where each voice is coming from.

Why can't I hear anyone?

The usual causes are a denied microphone permission, a parcel with voice turned off, standing too far from the speakers, or another viewer signing in as your avatar. Remember that voice starts a moment after you join, because the voice server waits to learn where your avatar is standing.

Is Second Life 18+?

Not entirely. Under Linden Lab's Second Life Terms and Conditions (effective 2 May 2024), residents aged 16 and 17 may access only the General area, and residents 18 and over get full access.

Is Second Life still active?

Yes. The grid is busy, Linden Lab ships updates regularly, and moving voice to WebRTC is one of the bigger recent changes. See our breakdown of who is still in Second Life.

Does anyone still use Second Life?

Plenty of people, from long-time residents and store owners to newcomers arriving through the mobile app. The Voice Chat Hot Spots list above is a good place to hear them for yourself.
