What Is an eSIM Card?
An eSIM is a digital SIM card soldered permanently into your phone's motherboard. It connects you to cellular networks for calls, texts, and mobile data. There is no physical card to insert, misplace, or swap out at the airport. The term e SIM is short for embedded SIM, and you may also see it written as e-sim. All three refer to the same built-in chip.
The GSMA, the organisation that manages global eSIM standards, defines the specification that lets you store and switch carrier profiles wirelessly. Most modern smartphones, iPads, smartwatches, and some laptops include an embedded SIM. Buy a HelloRoam plan before you fly, scan the QR code, and you are connected at every stop on your itinerary. What is itinerary travel? Your travel itinerary is your planned schedule of destinations. A HelloRoam eSIM covers 175+ countries, so one plan can follow your whole trip. Before you leave home, set a data warning alert before you leave. What is data warning? It is the notification your phone triggers when your remaining data is low, giving you time to top up before you run out.
How Does an eSIM Work?
Your phone uses built-in software to download and store a carrier profile from your data plan provider. Once active, you connect to local mobile networks for calls, texts, and data, exactly as you would with a physical SIM card. What is data mobile phone use? It is the internet connection your phone uses through a cellular network for browsing, maps, messaging, and streaming. An eSIM delivers that same data connection through a software profile instead of a physical card, so you never need to swap chips or visit a store. check our compatibility list
Getting started takes about five minutes: choose a plan, open your confirmation email, and scan the QR code. Your Bell, Rogers, or Telus physical SIM stays in your phone the whole time.

Why eSIM Beats Carrier Roaming for Canadian Travellers
eSIM Limitations Worth Knowing Before You Buy
Paying CAD 12 or more per day to Bell, Rogers, or Telus is expensive for any trip. HelloRoam eSIM puts you on local data rates instead. Here is what changes when you make the switch.
No more CAD 12-per-day carrier charges
Bell, Rogers, and Telus charge CAD 12 to CAD 16 per day for international data whether you use 100 MB or 1 GB. A HelloRoam eSIM connects you to local networks at local rates. Set it up at home before you head to Pearson, YVR, or Trudeau and arrive connected.
Multiple destinations, one phone
Store plans for the United States, Mexico, the Dominican Republic, and Europe on one device without opening the SIM tray. Switch between profiles in your phone settings in seconds.
Pay only for the days you travel
Heading to Cancun for 8 days or London for 12? Buy exactly the days you need. HelloRoam plans match your trip length so you never pay for data you aren't using.
Better hardware, same connectivity
Without a physical SIM tray, device makers can fit larger batteries and more durable hardware into the same size phone. That's a real engineering gain for every traveller.
Locked safely inside your phone
Lose your bag at Pearson or get pickpocketed in Mexico City? Your eSIM stays locked inside your phone. No one can access or remove it without your Face ID or fingerprint.
A greener choice for Canadian travellers
Every trip without a plastic SIM card is one less piece of waste. Choosing eSIM is a practical step toward greener travel that every Canadian can make right now.
Not sure if your phone supports eSIM?
Most phones released after 2019 support eSIM, but it's worth confirming your specific model before you book your trip. Check the HelloRoam compatibility list in under a minute.
Check CompatibilityeSIM vs Physical SIM Card: What Is the Difference?
A SIM card is a small removable chip you slide into your phone to connect to a carrier network. An eSIM (also called a digital SIM or e-sim) is embedded permanently inside your phone and does the same job without any physical card. Physical SIM vs eSIM: both handle calls, texts, and cellular data, but eSIM removes the need to visit a carrier store, handle a tiny card, or pay a per-day roaming fee each time you cross a border.

FAQs
An eSIM is a digital SIM card (also written as e SIM or e-sim) permanently embedded in your phone's circuit board. It stores carrier profiles so you can connect to local networks in 175+ countries without a physical card. You download the profile over Wi-Fi before your trip and your phone activates data automatically when you arrive at your destination. Most eSIM compatible phones hold up to 8 profiles at once.
eSIM is better than a physical SIM card for Canadians who travel internationally and want to avoid Bell, Rogers, or Telus daily add-on charges. With an eSIM, you load a HelloRoam plan over Wi-Fi before you leave Canada and connect the moment you land. The trade-off is that older phones do not support eSIM and the profile cannot be moved to a new device without contacting support.
HelloRoam eSIM plans cost up to 77% less than Bell's Roam Better at CAD 16 per day, Rogers' Roam Like Home at CAD 12 per day, or Telus' Easy Roam at CAD 12 per day, as of April 2026. You buy the plan before your trip, scan a QR code, and it activates when you land. No SIM hunt, no airport phone shop, no surprise charge on your next bill.
Most modern phones support dual SIM, so you can run a HelloRoam eSIM alongside your existing physical SIM at the same time. Keep your Bell, Rogers, or Telus SIM active for calls and texts while the HelloRoam eSIM handles data abroad at local rates. iPhone XS and newer, Samsung Galaxy S20 and newer, and Google Pixel 3 and newer all support this dual SIM setup.
An eSIM is not transferable to another phone once it has been installed. To move to a new device, remove the profile from your old phone and contact HelloRoam support for a new activation code. Travel eSIM plans tie to the specific device they were installed on, so always save your QR code and order confirmation as a backup.
eSIM has three main limitations: not all phones support it, the profile cannot be transferred to a new device after installation, and you need internet access to install it the first time. Older and budget phones still need a physical SIM card. If you upgrade your phone, contact HelloRoam to arrange a new plan. Some smaller regional carriers have not added eSIM support yet.
eSIM is worth it for any Canadian who travels to the United States, Mexico, Cuba, or Europe and wants to avoid Bell, Rogers, or Telus daily roaming charges. HelloRoam eSIM plans save up to 77% compared to carrier international add-ons. Buy a local data plan before your trip, scan a QR code, and it activates when you land. For frequent travellers, the savings are clear on the first trip.
HelloRoam travel eSIMs provide data only and do not assign a new phone number. Your existing Canadian number stays active on your physical SIM for calls and texts. The eSIM handles mobile data at local rates abroad, which cuts data roaming charges from your home carrier. For calling over Wi-Fi on iPhone, enable Wi-Fi Calling in Settings under Cellular and use your Canadian number over your HelloRoam data connection. WhatsApp and FaceTime Audio calls also work over the eSIM connection.
Your Canadian phone number stays active when you use an eSIM for travel. HelloRoam eSIM plans are data only, so your physical SIM card remains live for calls and texts with your current number. Both lines run at the same time on eSIM compatible phones. You choose which line handles data in your phone settings.
HelloRoam eSIM plans cover multiple countries, with regional options spanning Europe (30+ countries) or Southeast Asia on one profile. You can also store separate country plans and switch between them in your phone settings. Snowbirds and frequent travellers can pre-load plans for the United States, Mexico, Cuba, and the Dominican Republic before each trip. HelloRoam covers 175+ countries in total.
Turn off Data Roaming for your Bell, Rogers, or Telus SIM line and leave it on for your HelloRoam eSIM line. On iPhone, go to Settings, Cellular, tap your Canadian carrier line, and switch off Data Roaming. Leave Data Roaming enabled on the HelloRoam eSIM line so it connects to local networks abroad. What is data roaming for iPhone? On an iPhone, data roaming is the setting that allows your phone to connect to foreign networks and use mobile data outside Canada. Keeping it on for your eSIM line and off for your Bell or Rogers line lets you use HelloRoam data without surprise charges on your Canadian bill.
HelloRoam eSIM installation takes about five minutes on most eSIM compatible phones. Buy a plan on the HelloRoam website or app, open your confirmation email, and scan the QR code with your phone camera. On iPhone, go to Settings, Cellular, then Add eSIM. On Android, go to Settings, Network and internet, then SIM manager. Connect to Wi-Fi before you start for the smoothest experience.
