Oct 13, 2025 by talynt.org 57 views

Introduction

Google Fi is a popular mobile virtual network operator (MVNO) that offers a seamless and convenient way to manage your phone's cellular service. However, some users have reported experiencing issues with losing cell service when using a secondary profile on their primary Google Fi account. In this article, we will delve into the details of this issue and explore the troubleshooting steps taken by a user who encountered this problem.

Background

The user in question has a setup with an owner profile that manages the eSIM using Orbot, and a secondary profile that is used for daily activities with Proton-VPN enabled and the capability to receive calls and SMS turned on. The secondary profile has been working fine until the 2025030900 update, after which it started experiencing issues with losing cell service.

Troubleshooting Steps

The user took several troubleshooting steps to resolve the issue, including:

Restarting the phone: This fixes the issue if the problem persists in the owner profile, but when switching to the secondary profile, it will eventually lose service again.
Uninstalling and reinstalling Google Fi, then activating eSIM: This works fine with the owner profile, but eventually, the secondary profile loses service.
Removing eSIM and re-activating: At one point, it seemed Google Fi attempted to install a second eSIM as well, so the user deleted the first.
Disabling VPNs on both profiles, allowing data without VPN: The same behavior as above was observed.
Disabling data saving of Google Fi: The user had a thought that maybe Google Fi was being prevented from accessing the network when backgrounded, so they turned on the unrestricted mobile data setting.
Preventing battery optimization of Google Fi: The user had another idea that the battery optimization was killing the service when put into the background, so they turned that setting off for Fi.
Activating airplane mode in owner profile, turning it off: Service returns.
Activating airplane mode in secondary profile, turning it off: If the network says "Google Fi" with airplane mode turned on, the service is able to recover. If the network says "No service" it is unable to recover.

The user has attached system logs for the following actions:

Restart phone, confirm service in owner profile: The system log confirms that the service is working fine in the owner profile.
Switch to secondary, confirm service: The system log confirms that the service is working fine in the secondary profile.
