Why UK Travellers Choose This Bundle
What’s Included
Not Just a Data-Only USA eSIM
Many USA travel eSIMs only include mobile data.
That can be limiting in America. You may need a real USA number for calls, texts, bookings, transport, delivery services, roadside assistance, travel updates and verification systems.
This AT&T USA eSIM includes a real USA mobile number, USA calls, USA texts and mobile data.
Want a Lower Cost AT&T USA Bundle?
Check out the AT&T 12GB, 30GB and 50GB Bundle . It also uses the AT&T USA network, but costs less if you do not need unlimited data.
Need It Fast?

AT&T Unlimited USA eSIM FAQs
Clear answers for UK travellers about eSIM setup, iPhone compatibility, USA coverage, activation, support, and why this AT&T eSIM is different from many data-only travel eSIMs.
Why is this bundle eSIM only?
The AT&T Unlimited Bundle is eSIM only because it is designed for compatible iPhones. There is no physical SIM card option with this AT&T bundle.
It works with selected eSIM-compatible iPhones, including iPhone XR, iPhone XS, iPhone SE 2nd Gen, iPhone SE 3rd Gen, and iPhone 11 through to iPhone 17.
Unlike many USA travel eSIMs, this AT&T eSIM is not data only. It includes a real USA mobile number, unlimited USA calls and texts, and mobile data on the AT&T USA network.
Is the AT&T eSIM hard to install?
No. If you are comfortable using your iPhone, installing an eSIM is straightforward.
After ordering, you receive setup instructions by email. When your eSIM is activated, you will receive a standard notification on your iPhone screen. Tap it to download and install your eSIM. This eSIM is sent directly to the phone, so there is no QR code to scan. Setup takes just a couple of minutes.
Which network will this eSIM use in the USA?
Your eSIM connects to the AT&T USA network. This is a proper USA mobile service, not a basic data-only tourist eSIM.
AT&T USA network access
Coverage across mainland USA, Hawaii and Alaska
Canada roaming on Bell, Rogers or Telus
Mexico roaming on AT&T México
Real USA mobile number included
Does this eSIM include a real USA number?
Yes. Every AT&T Unlimited eSIM includes a real USA mobile number, unlimited USA calls and unlimited USA texts.
This is useful because many travel eSIMs only include mobile data. Data-only eSIMs usually do not support normal calls, incoming calls or SMS.
A real USA number can help with hotels, restaurants, rideshare apps, tour operators, bookings, US forms, travel alerts, delivery services and roadside assistance.
Your USA number will look like this: 310-123-4567. If someone calls or texts you from the UK, they use this format: +1 310 123 4567.
Can I choose my activation date?
Yes. You do not need to choose your activation date when placing your order.
After purchase, follow the setup steps in your order confirmation email and submit your activation details before you travel.
Your bundle is then prepared for the date you need it, so you can travel with your eSIM ready to use in the USA.
Flying soon or already in the USA?
We can help if you need your AT&T USA eSIM urgently.
Will I get support while I’m in America?
Yes. We provide support before and during your trip, so you are not left on your own if you need help with setup or activation.
Email and WhatsApp support
Help with eSIM setup and activation
Support if something does not work as expected
Do you offer a money-back guarantee?
Yes. If there is a fault with your eSIM and it does not work as described, you are covered by our money-back guarantee.
Please contact us if you need help. We will troubleshoot first, then advise the next step if the issue cannot be resolved.
AT&T Unlimited Bundle Footnotes
Please read these notes before ordering, especially if you plan to use Canada or Mexico roaming, international texts, the Gold Add-On, or high-speed data in busy USA locations.
* Canada and Mexico roaming
You must first use your eSIM in the USA to activate roaming for Canada and Mexico.
If you fly direct from the UK to Canada or Mexico, this AT&T Unlimited Bundle will not work until it has first connected in the USA.
If you are only transiting through a US airport on the way to Canada or Mexico, make a call or send a text at the airport to activate Canada and Mexico roaming.
If you are not entering the USA before Canada or Mexico, choose the T-Mobile Unlimited Bundle instead.

*** Information about data speeds
On the AT&T Unlimited Bundle, AT&T may temporarily slow data speeds if the network gets temporarily congested.
This is most likely to happen places such as packed stadiums, busy airports, major events, city centres and busy tourist areas. Once the congestion clears, or you move to a less congested area, speeds will improve
AT&T uses congestion-based network management. If a local cell site is busy, you may notice reduced speeds or higher latency. Once the congestion clears, or you move to a less congested area, speeds will improve.
Network demand can change quickly, so any slowdown may be brief and will depend on your location, signal strength and local network conditions.
