Step-by-Step eSIM Activation Guides

Pre-Departure Checklist: Ensure Smooth Activation
To avoid setup delays upon arrival, we strongly recommend taking these 3 quick steps before boarding your flight:
- Install Your eSIM at Home: Install your eSIM profile using Wi-Fi at home or at the airport before departure. Do not delete the eSIM profile once installed.
- Turn Off Primary SIM Data Roaming: Go to your primary physical SIM settings and disable Data Roaming before takeoff. This prevents unexpected carrier roaming charges while keeping your main line active for calls and 2FA texts.
- Save Your Order Details Offline: Take a screenshot of your activation instructions, APN settings, and order details in case you don’t have immediate Wi-Fi access upon arrival.
Troubleshooting: Why Is My Billion Connect eSIM Not Working?
If you have landed and your device displays “No Service”, “Searching”, or shows signal bars without internet access, follow these 7 troubleshooting steps:
- Ensure the eSIM Line is Active & Selected for Mobile Data
- Verify that your Billion Connect eSIM profile is switched ON in your SIM Manager/Cellular settings, and confirm it is assigned as your preferred line for Mobile Data.
- Turn ON Data Roaming (Most Common Issue). Make sure Data Roaming is explicitly turned ON under your eSIM line settings. You will not incur extra fees on your Billion Connect prepaid line.
- Verify APN Settings. If auto-configuration fails, open Access Point Names / Cellular Data Network settings and ensure the APN name matches the specific text in your plan confirmation email (e.g., 3gnet or vmail).
- Manually Select a Supported Local Network. Go to Settings > Cellular/Mobile Data > Network Selection. Toggle Automatic to OFF, wait for available networks to load, and manually tap one of the local partner carriers listed in your installation guide.
- Refresh Your Network Connection. Toggle Airplane Mode ON for 10 seconds, then turn it OFF. If the connection is still idle, restart your device to initiate a fresh handshake with nearby signal towers.
- Allow 5–10 Minutes for Network Registration. Roaming network handshakes can take up to 10 minutes when registering on a foreign cellular network for the first time.

Frequently Asked Questions (FAQ)
Q: Should I delete my Billion Connect eSIM after turning off my phone?

Q: When does my eSIM plan validity period start?
A: For most plans, validity begins the moment your eSIM connects to a supported local cellular network at your destination country, not when you scan the QR code at home.
Q: Can I share my internet connection via Personal Hotspot?
A: Yes! Billion Connect eSIMs support personal hotspotting/tethering on compatible devices. Ensure your primary device has APN settings configured properly for both mobile data and hotspot routing.
