Buy USA SIM Cards in Canada

SimCorner SIM cards are designed for a hassle-free setup. Just insert the travel SIM USA into your unlocked, compatible phone upon arrival, and it will activate automatically when it connects to a local US network. There is no complicated registration or bulky paperwork. With clear instructions included and 24/7 customer support, you will be connected and browsing within minutes of landing.

Your new US SIM card from SimCorner will give you a USA number for local calls and texts, but your Australian number can be kept if your device has a dual-SIM setup. It is not recommended unless you need your Australian number still active, as using it can incur roaming charges. However, you won’t have to change your +61 number attached to data apps like WhatsApp, Messenger, or FaceTime. This way, you can stay reachable on your home number without roaming.

After inserting the USA prepaid SIM card, your phone will connect to the network, and you will get a welcome message. In some cases, it will note that a top-up has been made. You can disregard this message as it is our activation team loading the plan on your SIM. If you face issues or did not receive this welcome message, our email support is always ready to assist you, be it on a Sunday at 3 AM.

First, check that your phone is unlocked and compatible with US networks. Also, make sure that you have switched on mobile data roaming and followed the setup guide as given. If it still isn’t working, contact SimCorner’s support team, and we can check the activation of your SIM—they will walk you through getting your travel SIM USA working quickly.

Every SimCorner travel SIM USA is prepaid and comes with set data, calls, and validity. While top-ups aren’t available, you can extend usage by purchasing additional SIM card(s) as required. Some US SIM cards also offer add-ons (like Canada/Mexico data or international call packs), but these must be included at the time of purchase—not as a top-up later.

Yes—each travel SIM USA has a set validity period from the activation date you nominate on the registration page. The validity is 30 days for all American SIM cards. Make sure to align your travel dates with your plan’s coverage window, so as not to waste validity on non-usage days.

Yes—SimCorner offers a US SIM card designed for newer iPads and tablets. It provides 15GB and 100GB data options with full hotspot/tethering support. As this SIM card for USA is data-only, it doesn’t include calls or texts, but the same are unrestricted via data-based apps. If you want network-based voice and messaging, choose a regular travel SIM USA. Always check compatibility, especially with iPads, to ensure smooth activation and browsing.

Many plans also include or allow add-ons for Canada, Mexico, or international minutes. Everything is prepaid and upfront, so you don’t have to worry about any hidden costs during your travels.

Except for one data-only SIM for tablets and iPads, all SimCorner USA travel SIM card plans include calls and texts within the USA (and Hawaii). High-speed data, however, comes with varying allowances like 10GB, 15GB, 25GB, or unlimited, depending on the plan you buy. SimCorner also has unlimited options for the USA, Canada, and Mexico travel, and add-ons for international talk in 70+ countries (with unlimited calls to Australia).

If your allowances are exhausted, you won’t be able to use high-speed data. However, your travel SIM USA includes unlimited calls and SMS to USA numbers, so you won’t run out of calls or texts. Furthermore, your number remains active during the validity period, so you can receive incoming calls. You can still use Wi-Fi for apps like WhatsApp or Messenger. To avoid such a situation, it is recommended to purchase a United States SIM card that matches your expected needs.

Yes—almost all SimCorner USA SIM cards allow hotspot/tethering, letting you share your mobile data with laptops, tablets, or travel companions. Note that our USA T-Mobile SIM Unlimited plan doesn’t support hotspot, while the USA AT&T SIM Unlimited has a 35GB restriction. All remaining travel SIM USA plans allow unrestricted sharing from your applicable data balance.

You won’t face any trouble with our travel SIM USA, unless you are in a very remote area where local coverage itself is weak or heavily congested. With high-speed 4G/5G coverage on leading networks like AT&T, T-Mobile, and Verizon, you can browse, stream, video call, and use social media apps without interruption.

The unlimited calls that come with our US SIM card can only be used to call standard US landlines and mobiles. If in the US and trying to call a US number, then no country code will be required in this instance, unlike with cross-country calling. For international calls, however, we recommend that you use data-based apps such as WhatsApp, Viber, Skype, etc. to make international phone calls rather than adding credit for the same.
