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.
