Coverage: USA, Hawaii, Canada, Mexico, Alaska.
Please note when searching the coverage in Canada, only refer to the colour 'orange' on the Canada map. Where ever it's showing the color orange on the map in Canada, it means there is coverage there but the text that comes up will note 'No Coverage'. This is because the actual carrier of the sim AT&T doesn't have a their own network in Canada and that their network partner in Canada is Rogers so they can't provide specific details regarding a different companies network. The colour 'orange' is shown in the legend/key of the map as "off-network" coverage, meaning it's not their own coverage/network but it's on another network.
This does not apply for USA and Mexico since AT&T have their own networks in those two countries so searching coverage for cities and towns in USA and Mexico will be more clear.
- Unlimited Data in USA, Hawaii, Alaska
- 25GB Data in Canada and Mexico
Please note AT&T does advise that data speeds are at max 3Mbps (Upload/Download). After 30GB usage, speeds are reduced to a max of 1.5 Mbps (Upload/Download) for the remainder of the 30 days. The carrier does this to free up the 4G data network congestion for their customers and to not effect their other customers who haven't used much data instead of it effecting all their customers.
- Unlimited Calls and SMS to USA , Canadian and Mexican Mobiles and Standard Landline number
The unlimited calls that come with the sim can only be used to call standard US, Canadian and Mexican landlines and mobiles.
When calling Canadian or Mexican numbers, you must ensure you use their respective country codes dialling. For Canada it's +1 and for Mexico it's +52. Even if in Canada or Mexico you must use their country codes to call a local number. If calling a US number from Canada or Mexico, then you must ensure you put the US country code when dialling which is also +1. However, if in the US and trying to call a US number, then no country code is required in this instance.
The unlimited local SMS/texts that come with the sim can be used to text US, Canadian and Mexican mobiles. The same process still applies for texting in terms of using the country codes as noted above. .
The unlimited international texts can be used to text over 100 countries from the USA, Canada and/or Mexico. You can find the list here.
Please ensure you dial the country code for the country you are trying to text. For example, Australia is +61 so please ensure you dial +61 followed by the mobile number without the leading zero when texting.
To get the plus (+) symbol you just hold down the zero key on your phone when dialling.
This sim does not come with international calling for other countries. We recommend that you use data based apps such as Whatsapp, Viber, Skype, etc to make international phone calls. You are also able to add credit to your Viber or Skype account, which will allow you to make local and international phone calls directly to landlines and mobiles at the apps rates.
The plan will last 30 days from the activation date provided. If you are staying longer than 30 days and wish to recharge the sim you can do this by either going into an AT&T store or calling AT&T customer service on 611 from your mobile handset. To recharge this same plan for another 30 days in the US with AT&T, will cost $65USD + Tax. If you have purchased the hotspot/tethering add-on then it will cost $75USD + Tax to recharge the plan. If you don't need the same plan for the following month or only need a few more days of service, then just let AT&T know and they will provide you some prepaid plan options to change to.
Alternatively, you can look to purchase multiple sims to cover your duration if travelling for more than 30 days. For example, if you are travelling for 56 days and are departing on the 1st of September, then you should select '2' for the quantity (qty) and add them to the cart. Then in the cart page enter the activation date for the first sim as 1st September and then press the "+" to enter the activation date for second sim as 30th September (you can select whatever activation date you like or even have them overlap, just keep in mind that your 30 days will begin from that date). You can then use the two sims for 30 days from the dates you have provided. (Please note: each sim card will have a different phone number).
As long as you are aware your 30 days will begin from the activation date you provide for each sim, it's up to you what date you provide ensuring it covers you for your duration. It's fine to have services overlap.

A Must-Have for Travelers!
I recently traveled through Alaska and decided to order a local SIM card from SimCorner to stay connected throughout my journey. It was hands down one of the best decisions I made for the trip! From the start, the strong signal and reliable coverage impressed me. I explored diverse areas—from bustling Anchorage to remote wilderness spots—and was able to stay connected nearly everywhere. Having a dependable network was incredibly helpful for checking maps, weather updates, and local recommendations in real time, especially in places where other travelers were struggling with coverage. This SIM card allowed me to stay in touch with loved ones, share photos instantly, and even get quick access to local attractions and events. Whether I needed restaurant recommendations or last-minute updates on hiking trails, the connection kept me well-informed and safe. If you’re planning a trip to Alaska and want to stay connected without any hassles, this SIM card is a fantastic choice!
Total Travel Game Changer!!!
So we ordered a US data sim for a 3 week holiday to the USA after hearing about the horrendous charges UK phones are landed with. It’s been amazing - the ability to use Google maps to navigate all day long if we wish plus the kids get to hot spot their phone onto the US sim and avoid all charges - also keeping them entertained for long road journeys. It has been well worth the initial expense and we’ll definitely buy again if travelling long haul.
Sim on the Go.
Hi changed Sim on the flight in to LAX, tried mobile and nothing,what? Actually I arrived a day earlier than activation date : oops. Anyway, it's working great so thru Edmonton and Toronto now on the flight to Chicago. Return to Melbourne on the 28th July. All's well, good coverage and will get one also for my next trip. Thanks.
