As teased last June, Linden Lab just announced private Alpha tests of its upcoming iOS/Android mobile app for Second Life starting now — if, that is, if you have a new-ish device, and you're a Premium+ subscriber:
For now, the Private Alpha is only open to Second Life Premium Plus users. We’ll be reviewing applications and adding qualifying Residents to the Private Alpha program on an ongoing basis. Please be patient with us as the demand is high but our staff is small! All Premium Plus subscribers are eligible to participate in the Private Alpha, however we’ll be adding users in small groups over time.
The Second Life mobile app is currently being developed and optimized for both iOS and Android devices. To participate in the Private Alpha, you’ll need either an iOS device (min version: iPhone X running iOS 16.6.1) or a mid-to-high-end Android device (comparable to Pixel 6 or higher) running Android OS 13 or higher.
I don't have data on how many SL users have a Premium+ subscription, which costs $25/month or $250/year, but it could be quite a lot:
