Setting your Gohub eSIM as the default data line ensures your phone uses Gohub's network for mobile data, not your home SIM.
iOS
- Go to Settings → Mobile Service
- Tap Mobile Data
- Select your Gohub eSIM
- Turn off Allow Mobile Data Switching. This prevents your phone from automatically switching back to your primary SIM's data without you knowing.

Android
- Go to Settings → Connections
- Tap SIM Manager
- Scroll down to Preferred SIMs
- Under Mobile Data, select your Gohub eSIM

⚠️ If you skip this step, your phone may continue using your home SIM for data - which could result in unexpected roaming charges from your home carrier.
📌 Already done this during installation? You're all set - no need to repeat it.
