Travel eSIM plans for 190+ destinations

An eSIM is a digital SIM built into modern smartphones. Instead of inserting a plastic card into a SIM card slot, you download a mobile plan over the internet. RoameSIM sells prepaid travel data plans: you buy an eSIM online, receive a QR code by email, and add the plan in your device settings. There is no shop visit and no postage wait.

Travel eSIMs are data-focused mobile plans for abroad. They give you mobile data on local networks at fixed prices, so you can skip expensive carrier roaming. Most RoameSIM packages are mobile service for internet use (maps, messaging apps, email and browsing). They are not a replacement home phone line, but they keep you online from the moment you land.

Dual-SIM phones and your phone number

On dual-SIM phones you can keep your everyday SIM active for calls, SMS and your phone number, while the travel eSIM handles mobile data. Open device settings, install the digital SIM profile, turn on data roaming for that line, and set mobile data to the travel plan. You usually do not remove your physical SIM; many phones support eSIM technology alongside the card in the SIM card slot.

eSIM compatible devices

Before checkout, confirm your device supports eSIM and is unlocked. Most recent iPhones from XS onward, Google Pixel 3 and newer, and many Samsung Galaxy models from S20 onward are eSIM compatible devices. Use the checker on any plan page, or read our guide to phones that support eSIMs. If your handset has no eSIM chip, you will need a physical travel SIM instead.

Why travelers buy a RoameSIM data plan

Compared with airport SIM kiosks or daily roaming add-ons, a prepaid data plan is often cheaper and faster to start. Pick a country or regional package, pay securely, and install before you fly or at the gate on Wi-Fi. RoameSIM covers 190+ destinations with clear validity and data allowances, so you can compare sim-only style travel plans in one store.
