ATT Prepaid SIM FAQ

First things first... Activation

Give us your Activation Date ✈️

You will be prompted at checkout to select the Activation Date for your SIM.

Your Activation Date is the date that you will need your SIM to be connected for use.

We recommend choosing the date that you land - keeping in mind that we activate on the date you selected at 2 pm AEST (4 am GMT). Your SIM will not work unless you have given us your activation date.

Once activated, connection to the network can take anywhere from a few minutes to a few hours.

If you are unsure, you can choose an estimated date and reach out to us to change it 🗓

How does activation work?

  1. We will activate your SIM card on the date that you provide during checkout.

  2. Once you arrive at your destination country, insert the SIM into your device.

  3. Turn on Data Roaming in your settings

  4. Restart your device

Easy peasy! 🙌

Contacting AT&T Mobile

If you're having issues with your SIM, you can get in touch with AT&T Mobile Customer Service. The options to contact them are:

  1. Dial 611 from your phone

  2. Dial 888-331-0500 from another phone

How do I find my mobile number?

Your new US mobile number will be texted to you after activation in the US.

How do I check my balance?

How do I recharge?

As described on the website, the SIM is non-rechargeable. The only way around this is to buy multiple SIM cards and swap them out as you go.

How do I make calls/texts?

Within USA

Simply call or text the US phone number.

Within Canada

Simply add the Canadian country code +1 in front of the number.

For example, if the phone number is 7939158158 then you will need to dial +1 7939158158 (To get the + on a mobile phone, press and hold 0 until it turns into a +)

Within Mexico

Simply add the Mexican country code +52 in front of the number.

For example, if the phone number is 7929148988 then you will need to dial +52 7929148988 (To get the + on a mobile phone, press and hold 0 until it turns into a +)

International Calls

We recommend using data apps like Whatsapp, Viber, Skype or Messenger to make calls/texts to overseas numbers!

Is my phone compatible?

How do I know if my device is unlocked?

If you bought your device outright, it's most likely unlocked!

If you're unsure, the best way to find out is to call your Aussie network provider and ask! They'll be able to unlock it for you too. This might incur a fee! 🤔
