What to consider before buying a US SIM card?
Before choosing a plan, it helps to think about your device and travel needs. Here are a few key points to check:
- Is your phone unlocked? You may not be able to use a local SIM or eSIM if your device is carrier-locked to your local carrier.
- Use SIM or eSIM? eSIMs offer quick digital installation. If you’re new to the technology, guides like the USA eSIM buying guide can help simplify the process.
- How much data do you need? Consider whether you’ll rely on navigation, streaming, or hotspot usage. You can also use Holafly’s data calculator to have a better idea of your daily usage.
- Network coverage: US is large, and the coverage varies. For reference, travellers can review the best US tourist destinations to check which networks perform well in those areas.
- Roaming vs. local SIM? Some travellers prefer to keep their Canadian number active instead of switching to a travel SIM.
- Trip essentials: Since connectivity is tied to overall travel readiness, many travellers also review what to pack for the USA to avoid last-minute issues when setting up their SIM or eSIM.
Best US SIM/eSIM options for Canadian travellers
Travellers generally choose between three types of options: US carrier prepaid SIMs, online travel eSIMs, and Canadian carrier roaming. Below is a breakdown to help you compare.
US carrier prepaid SIMs & eSIMs
Major US carriers like AT&T, T-Mobile, and Verizon offer prepaid SIM and eSIM plans with strong nationwide coverage. These options are ideal for travellers who want high speeds and reliable performance, especially in suburban or rural areas.
However, if you’re considering in-store pickup on arrival, keep in mind that availability varies by location. For more prepaid SIM information, you can check out Holafly’s US prepaid SIM buying guide.
Online travel eSIM providers
Travel eSIM providers, such as Holafly, are currently the most searched choice among Canadian travellers. They offer quick digital delivery, flexible plans, and easy installation. This category is especially popular with travellers who want to avoid lineups or complicated activation.
Holafly’s unlimited data US eSIM is especially appealing to travellers who prefer predictable pricing without worrying about overages.
Canadian carrier US roaming options
Roaming with your existing Canadian carrier is often the most convenient choice, especially if you want to keep your current number active and avoid switching SIMs. It works right away on arrival, making it a familiar option for travellers who prefer minimal setup.
If you’re comparing plans, you can check your carrier’s specific roaming details — such as the Rogers US roaming guide, Bell US roaming guide, or Telus US roaming guide — to see what daily fees, data limits, and coverage you can expect during your trip.
Roaming is straightforward, but it’s often the most expensive option. For trips longer than a few days, using a local US prepaid SIM or a travel eSIM offers better value and more flexibility.
How to set up a US SIM / eSIM from Canada
Setting up a US SIM or eSIM is generally straightforward. This section outlines the basic steps for both physical SIMs and eSIMs, so you know what to expect.
Setting up a physical SIM
- Purchase a SIM online or in-store.
- Insert the SIM into your unlocked device once you arrive in the US.
- Follow the activation steps provided by the carrier.
- Set your APN settings if required (instructions vary by provider).
Some travellers prefer buying a SIM card in advance, though installation typically happens once you enter the US.
Setting up a US eSIM
- Choose your plan from a provider such as Holafly or AT&T.
- Receive your eSIM activation code by email or through an app.
- Scan the QR code or install it directly onto your device.
- Enable the eSIM once you reach the US and connect to a local network.
Most US eSIMs can be installed in Canada, allowing you to set everything up before your trip. Only the activation (i.e., data usage) begins once you arrive in the US.
