Projects:
- Wearables for Android - Samsung watch & Pixels watch - add eSIM to watch itself, pair the number w/phone so you don't need your phone around to take calls
- Seamless Onboarding - product differentiator - when you purchase a new device in store or even if it gets delivered to your house, it will automatically connect to your home Wifi if you're a Spectrum internet customer.
- eSIM / HMNO continues to be track one, ongoing work
- Sierra - iOS Speedboost - their connection manager is installed on all Spectrum Mobile devices except Apple, because iOS won't let you install OEM. When you turn on your Android device as a Spectrum customer, the welcome screen shows as Spectrum but on iOS devices it shows the apple logo. All non-iOS users on Spectrum network have no issues with wifi speedboost because their devices automatically connect. 20+M requests a day for Android - there are way most iOS users so this is a huge part of the market that needs to be able to offload to Spectrum's network
- phase 1 they tried to do it through MSA but iOS wouldn't allow it to run in the background
- phase 2 was using ML model for their routers to identify any iOS device (both customers and non customers) and speedboost everyone - temporary solution
- now phase 3, Sierra, finally working with Apple to install their connection manager on Apple devices.
