David T.An e-sim is a digital SIM card built directly into your smartphone, tablet, or smartwatch. There is no physical chip to insert. Scan a QR code to download the eSIM profile and connect to a local network within minutes. eSIM cards are reprogrammable, so switching plans or carriers takes no SIM tray and no store visit. eSIM compatible phones include iPhone XS and later, Samsung Galaxy S20 and later, and Google Pixel 3 and later.
Open Settings, then Cellular on iPhone or Network and Internet on Android, and look for "Add eSIM" or "SIM card manager". Most phones released after 2018 include eSIM support, including iPhone XS and newer, Samsung Galaxy S20 and above, and Google Pixel 3 and later. You can also dial *#06# to check for an EID number.
Installing your HelloRoam eSIM takes three steps. First, purchase your plan from the HelloRoam app or website and get your QR code by email within minutes. Second, open Settings, tap Cellular or Mobile Data, then tap Add eSIM. Third, scan the QR code, confirm the installation, and you're ready. The whole process takes about 2 to 5 minutes. Keep a Wi-Fi connection during setup.
eSIM activation usually completes within 2 to 10 minutes after scanning the QR code. If it takes longer, try toggling airplane mode on and off for 30 seconds, restarting your device, or confirming your eSIM line is set as the active data line in your cellular settings.
Most modern phones support dual SIM, letting you run a physical SIM and an eSIM at the same time. Canadian travellers often keep their Bell, Rogers, or Telus SIM active for calls and texts from home, while using the HelloRoam eSIM for local data. Set which SIM handles data in your device's cellular settings.
HelloRoam supports 5G, 4G LTE, and 3G networks where available. Your device connects to the fastest network at your location automatically. To use 5G, your phone must be 5G-capable and the local partner network must offer 5G coverage. Many popular destinations for Canadians, including Greater China, include 5G access where it's available.
Check your data usage two ways. First, log in to the HelloRoam dashboard at helloroam.com to view real-time usage and your plan's expiry date. Second, check your device settings: iPhone users go to Settings, then Cellular, then tap your eSIM line. Android users go to Settings, then Network and Internet, then Data Usage. HelloRoam also sends an alert when you've used 80% of your data.
HelloRoam offers refunds on unused eSIM plans within 180 days of purchase. If the eSIM has not been activated, you can request a full refund. Contact our support team with your order ID and we'll process it within 5 to 14 business days.
Each QR code works once for security reasons. Your device locks to that code at installation. To reinstall, open your HelloRoam account and select the reinstall option, or contact our support team. We handle most reinstall requests in under 2 hours. You cannot transfer an eSIM to a different device after activation.
HelloRoam support is available 24/7 by live chat, WhatsApp, and email at help@helloroam.com. Most queries get a response in under five minutes. The team helps with eSIM setup, connection troubleshooting, plan changes, and refund requests.
