Can I Keep My Home Number Active While Using a Travel eSIM?
The Magic of Dual SIM
One of the biggest concerns travelers have is: "If I use a travel data plan, how will my bank send me a 2FA text message to authorize a credit card purchase?" The beauty of eSIM technology is that it allows for a Dual SIM setup.
How Dual SIM Works
Modern smartphones can have two active cellular lines at the same time: your physical home SIM card, and your downloaded BlingSIM eSIM.
The Perfect Travel Configuration
To receive important texts from home without paying data roaming fees, follow these steps:
- Turn OFF Data Roaming on your Primary (Home) line. This ensures your home carrier cannot charge you for background app data.
- Leave the Primary line active. This allows incoming SMS texts (which are usually free to receive globally) to come through.
- Set your BlingSIM eSIM as the default line for Cellular Data. Now, your phone will use BlingSIM for all internet traffic.
- (Optional) Disable Wi-Fi Calling on your primary line if your carrier charges international rates for Wi-Fi calls.
VoWi-Fi over Cellular Data
If you have an iPhone, it can perform an incredible trick: it can route your home carrier's "Wi-Fi Calling" feature through the cellular data of your BlingSIM eSIM. This means you can actually make and receive phone calls from your home number, using the BlingSIM data connection, completely bypassing international voice roaming rates!
