What is an eSIM?
An eSIM is a digital SIM built into your phone. You connect to mobile networks without a plastic card, and you can store more than one profile — ideal for travel.
Versus a physical SIM
After purchase you install via QR or SM-DP+ in minutes. No airport kiosk, no swapping the card you already use at home.
When it starts
Most plans start at first connection. Install before you fly; turn the line and data roaming on when you land.
Keep your number
Leave your primary SIM for calls. Use HopRoam for data. WhatsApp and iMessage stay on the account you already have.
Calls and SMS
Travel plans are usually data-only. Use messaging apps unless the product page includes voice.
