💡 Cost-Saving Tip: Avoid Charges from Your Primary SIM

Even if you don’t use your main SIM for data, receiving calls or texts can still incur roaming charges. Check with your domestic provider before you travel on the costs to receive calls and SMS whilst travelling.

To fully protect yourself:

• iPhone: Go to Settings > Mobile Data > SIMs → Toggle off your primary SIM
• Android: Go to Settings > SIM Manager → Toggle off your primary SIM

This ensures that only your travel eSIM is active, preventing accidental charges while staying connected. 

WARNING: Turning off your Primary sim will mean that people cannot call or SMS you. They can still call and message on data messaging services like iMessage and Whatsapp on your primary number but not standard SMS or cellular calling.
