Mexico Prepaid Travel SIM Card

You'll have unlimited data across the USA and Mexico—including Hawaii, Alaska, and Puerto Rico—on the AT&T network, known for its strong 4G and 5G coverage. In Canada, you can use up to 25GB of roaming data while connected to Rogers or Telus.

AT&T offers high-speed 4G and 5G in most areas across the USA, including Hawaii. Speeds may vary depending on location and coverage. You can check AT&T coverage map here.

Dial *#06# – if you see a 32-digit EID, your phone supports eSIM.

Check your device's compatibility with the AT&T network using this tool.

Important: AT&T can be strict with overseas models. Please check compatibility to avoid issues. Phones from mainland China (e.g. Huawei, Oppo, Vivo, Xiaomi) may not work with this network.

Yes – a local US phone number will be assigned when your eSIM activates. You can find it in your phone settings, or by dialling #611# once active. You may also receive your number via SMS after activation.

The phone number is only generated once the eSIM activates. If you’d like to retrieve your number earlier, you can choose to activate the eSIM a day or two before your arrival. Just keep in mind that this will also start your service period from the moment it’s activated.

No – cruise ships rely on satellite networks, which aren't supported by this eSIM. However, once you're near a port with mobile towers, your eSIM will reconnect and work as normal.

This eSIM is designed primarily for smartphones. While some tablets support eSIM, we cannot guarantee compatibility on all non-phone devices.

Our support team is available daily via live chat and email at hello@globalstarlink.com.au. We're happy to assist you with any questions.

Your eSIM will activate automatically from around 8 AM Pacific Time (Los Angeles time) on the start date you selected at checkout (typically your arrival date).

• iPhone: You’ll receive a push notification once the eSIM is activated. Follow the prompts to complete setup.
• Android: After the activation time, connect to Wi-Fi and scan the QR code in your confirmation email to complete installation.

Once the eSIM is installed:

• Set it as the default for Mobile Data, Voice, and SMS (in your device settings).
• Turn on Mobile Data and Data Roaming (if visiting Canada or Mexico).

We usually recommend using your device settings to check your data balance for the AT&T SIM Card or eSIM. Unfortunately, aside from this method, there are no other ways to check your data balance. Depending on your device type, please use the following steps:

iOS: Settings > Mobile > Current Period (or Current Period Roaming)
Android: Settings > Network & Internet > Data Usage

Note: Since this eSIM includes unlimited data, top-ups aren't required. If you need to extend your service, contact us before your plan ends.

If your trip is longer than the eSIM duration, contact us before your plan expires to explore extension options or purchase a new eSIM (a new number will be assigned).

Hotspoting is available, but it's limited to a maximum of 5GB for every 30 days. Due to the small data allowance, we don't consider it a key feature.

First, check your data usage to make sure you haven’t run out, and confirm that you’re in a country included in your eSIM plan. If everything looks fine, try toggling Airplane Mode on and off, restarting your device, or manually selecting a network in your phone’s settings.

For step-by-step instructions, refer to our eSIM Troubleshooting Guide. If you're still having issues, reach out to our support team and we’ll be happy to help.

AT&T eSIMs include unlimited calls and texts to local USA, Canada, and Mexico phone numbers. When calling or texting Canada or Mexico, make sure to use the correct country code. You can also use messaging apps like WhatsApp, iMessage, and Messenger to stay connected over Wi-Fi or mobile data.

To call a number in Canada or Mexico, make sure to include the correct country code before the phone number:
Canada: +1
Mexico: +52
For example, to call a number in Mexico, you would dial: +52 [phone number].

Yes – you can keep your Australian number while using this eSIM. If your phone supports dual SIM, leave your Australian SIM in the device, but make sure Data Roaming is turned off for it. Then, set your travel eSIM as the primary for Mobile Data. This way, you can still receive calls and texts to your Australian number over Wi-Fi or regular mobile signal (depending on your provider) without incurring roaming charges.
