eSIM Guides
Before buying a travel eSIM, you need to confirm your phone is eSIM-compatible and unlocked. Here is how to check — for iPhone and Android.

Buying a travel eSIM is straightforward — but it only works if your device is compatible and set up correctly. Before purchasing, it is worth spending a few minutes checking your phone. This guide explains what to look for.
Having eSIM hardware is the first step, but it is not enough on its own. Even if your phone has an eSIM chip, your carrier must have activated the eSIM capability on your account and your device must be unlocked to use eSIM profiles from other providers.
When you purchase a travel eSIM from RoameoGo, you receive a QR code or activation code by email shortly after checkout. You go into your phone’s settings, scan the QR code and download the mobile profile. Once installed, the eSIM connects to local networks at your destination.
If your phone is carrier-locked, a travel eSIM from RoameoGo may not work. Contact your carrier to ask if your phone is locked and whether they can unlock it before your trip. Unlocking policies vary — some carriers do this free of charge, others require your contract term to be complete.
The main practical difference is convenience. There is no card to buy at an airport kiosk, no risk of losing your home SIM during the swap, and no SIM tray to fiddle with. Most compatible devices support running a physical SIM and an eSIM at the same time, letting you keep your home number active for calls while using local data abroad.
Some home carriers include international roaming in their plans at no extra cost. If you are only travelling for a very short trip, it may be worth checking with your provider before purchasing a separate eSIM.

Being on a contract does not automatically mean your phone is locked. Many contract phones are unlocked — check with your carrier. If your phone is locked, you may need to request an unlock before using a travel eSIM from another provider.
Yes — you need a Wi-Fi connection to download and install the eSIM profile. Once installed, the eSIM connects to mobile networks and Wi-Fi is no longer needed for normal use.
