LinkUp Mobile Plan

An eSIM (short for embedded SIM) is a built-in digital SIM card that comes with most newer smartphones. Unlike a physical SIM, there's no need to insert anything because it's all set up electronically.

Using an eSIM means you can connect to mobile networks in the USA quickly and easily, without waiting for a physical SIM card to arrive in the mail. It’s a smarter, faster way to stay connected while travelling.

🚀 How Our USA eSIM Works

Here’s what to expect when you purchase a USA eSIM from us:

1. Place your order on our website

2. Follow the eSIM activation instructions in your order confirmation email

3. The eSIM installs on your phone and the whole process takes about a minute

4. You’re ready to use your phone in the USA just like you would at home

5. You’ll receive a real USA mobile number, with full calling, texting, and unlimited data, just like our physical SIMs.

💡 New to eSIM? Don’t Worry.

We understand that eSIM might be unfamiliar if you’ve only ever used traditional SIM cards. But rest assured, the process is simple and beginner-friendly, and there's no need to remove your current SIM if you don’t want to.

Many eSIM providers only offer data-only plans with no voice or text, but with our USA eSIM, you’ll get:

• A genuine USA mobile number

• Ability to make and receive phone calls

• Send and receive standard SMS texts

• Unlimited 5G/4G data

• Coverage across mainland USA and more

And if you ever need help, our local support team (based in Australia) is here for you: no bots, just real people who care.

💡 Tip: Dial *#06# on your phone: if you see an EID number listed, your device supports eSIM.

Setting up your eSIM is super easy and even simpler than using a physical SIM card. No need to remove your Australian SIM or worry about swapping anything out.

✅ As soon as you order, you’ll receive setup instructions by email.
✈️ When you land in the USA, your eSIM will automatically connect. No waiting, no fiddling with that annoying SIM removal tool.
📱 It’s all digital, and takes just a minute to install.

Perfect for Aussie travellers, the eSIM means you’re connected the moment you arrive, with no trips to a US store and no SIM tools required.

If you're an Aussie traveller and need a USA eSIM in a hurry, we’ve got you covered. We can usually have your eSIM up and running very quickly, within just a few hours.

If your flight is soon, just place your order and reply promptly to your confirmation email, and we’ll do the rest!

Absolutely! And we recommend it! You can order your USA eSIM/SIM as far ahead as you like. It's the smart choice to plan early and avoid last-minute stress before your trip.

No need to worry about the start date either, because your eSIM/SIM only activates from the date you select during activation, not the day you purchase it.

So go ahead and get organised early, and your eSIM/SIM will be ready when you are.

Nothing changes because everything on your phone stays exactly the same.

Swapping out your Australian SIM Card with a USA SIM or adding a USA eSIM does not delete or change your photos, contacts, apps, emails or settings. All of that is stored on your phone itself, not on the SIM Card.

So when you insert your USA SIM or install your USA eSIM while travelling, everything remains just as you left it. And when you return home and reinsert your Australian SIM, your holiday photos and all your apps will still be right there on your phone.

The activation instructions for your eSIM or physical SIM are super easy, and even a technophobe can do it. But we also offer an optional in-home setup service for customers in Sydney.

One of our experts can visit you at home to help set everything up, including:

• Inserting the SIM Card into your phone

• Setting the correct APN (internet) settings

• Choosing your activation date

• Answering any questions you have

This personalised service is ideal if you're not confident with tech or just want peace of mind before you travel. The cost is $250, and it’s available by request only.

🛑 This service is not available to purchase on the website: to book or find out more, email us at info@usaprepaidsimcard.com.au.

✅ Yes: our SIM Cards and eSIMs work in Hawaii. You’ll get coverage in most populated areas across the islands. However, like many remote or mountainous regions, there may be limited or no signal in certain isolated locations.

🚫 Alaska: Please note that our T-Mobile Unlimited Plan and T-Mobile 10GB Plan do not include coverage in Alaska. Our AT&T Unlimited Plan (for iPhone only) does work in Alaska.

Yes: both our T-Mobile Unlimited Plan and T-Mobile 10GB Plan offer an optional Canada & Mexico Add-On Pack.

With this add-on, you can use your SIM or eSIM while travelling in Canada and Mexico, including:

• Unlimited calls & texts to the USA, Canada, and Mexico

• 5GB of 4G data (per 30-day period, depending on your plan)

👉 You’ll need to select this add-on at the time of purchase, as it can’t be added later. See your plan’s product page for more details and pricing.

And our AT&T Unlimited Plan (for iPhone only) includes 25GB data in Canada and unlimited data in Mexico.

Our T-Mobile Unlimited Plan and T-Mobile 15GB Plan SIMs and eSIMs run on the T-Mobile USA network, which offers extensive 4G and 5G coverage across most of the country (including Hawaii), including cities, highways, and many regional areas. However, please note there is no coverage in Alaska. The coverage maps on the T-Mobile website provide an approximate guide to outdoor coverage only. If your location shows as “Partner” coverage (often in remote regions), service may not be available.

Our AT&T Unlimited Plan runs on the AT&T network, which offers extensive 4G and 5G coverage across most of the country (including Hawaii and Alaska), including cities, highways, and many regional areas. The coverage maps on the AT&T website provide an approximate guide to outdoor coverage only. Make sure to click/tap 'AT&T Prepaid' before entering your address. 

Mobile coverage can be affected by:

• Local terrain and elevation

• Weather conditions

• Buildings and obstructions

• Signal strength and phone model

📍 Always check the coverage maps using your exact address before purchase to confirm service availability in the areas you’ll be visiting.

Our USA SIM Cards and eSIMs are directly from T-Mobile and AT&T, which are two of the major mobile networks in the United States. We do not sell reseller or MVNO (Mobile Virtual Network Operator) products.

To explain: in Australia, Telstra, Optus, and Vodafone are the three main networks, but there are many resellers that operate under them (like Aldi Mobile, Kogan Mobile, or Coles Mobile). These MVNOs typically have limited access to the full network, which can result in reduced coverage or slower data speeds.

The same is true in the USA. T-Mobile and AT&T are major carriers, but there are dozens of resellers using its infrastructure — such as Ultra Mobile, Simple Mobile, H2O, Net10, and Tracfone. These MVNOs often offer cheaper plans, but they may come with speed restrictions, reduced priority on the network, or limited roaming support.

✅ With us, you're getting a genuine T-Mobile or AT&T product (not a third-party reseller SIM). That means full network access, reliable speeds, and broader coverage.

No: our USA SIM Cards and eSIMs will not work in Australia. They are designed exclusively for use in the United States (and optionally Canada/Mexico if you purchase the relevant add-on).

There is no roaming or local network support in Australia, which means the SIM or eSIM won’t even connect to any Australian mobile networks. If you’re hoping to use the SIM/eSIM while still in Australia, for example, to verify social media accounts, bank logins, or receive SMS then unfortunately it will not work.

🛑 Important: Please do not purchase our SIM Card or eSIM if you need a USA number for verification while still in Australia. You’ll need to wait until you’re physically in the USA to use it.

✅ Yes we do!

We offer both eSIM and physical SIM Card options for travellers heading to the UK and Europe.

Visit our dedicated website: ukprepaidsimcard.com.au to browse plans, check compatibility, and purchase online.

Our UK & Europe SIMs give you:

• A real UK mobile number

• Unlimited calls and texts in the UK and Europe

• High-speed data (4G/5G depending on coverage)

• Easy activation with full instructions provided

• Reliable service on the Three UK network with roaming across 40+ European destinations

• 100% Aussie customer support

Whether you’re going to London, Paris, Rome or beyond, we’ve got you covered.

✅ Yes, your phone must be network unlocked to use our UK & Europe SIM or eSIM. The good news? Most Australian phones are already unlocked, but it’s worth checking just in case.

📱 How to check if your phone is unlocked:

1. Go to Settings > General > About
