USA SIM & eSIM with Unlimited Data for UK Visitors to the USA

Many travel eSIM companies only provide roaming access to local networks. This means your data goes through their home network (e.g., in Europe or Asia) and the local carrier treats that connection with lower priority. That often results in slower speeds and less reliable coverage.

Our eSIMs work differently. Our eSIM connect directly to America’s T-Mobile network. It’s just like using a proper carrier eSIM, the same thing you’d get if you bought it from a T-Mobile store in the USA.

A simple comparison helps. A traveller in the UK can use a cheap third party eSIM or an official EE eSIM. The cheap option might only roam onto Three, send traffic through overseas routes, and receive second tier priority. The official EE eSIM will use the local EE network natively and gets full speed and stability like any other EE customer.

To use our physical SIM
• iPhone 8 and newer
• Most other 5G model phones including Samsung Galaxy, Google Pixel, Oppo, Motorola, Nokia, Xiaomi, and Huawei models. NOTE: phone must be a 5G phone

For an eSIM
• iPhone XR, XS, SE 2020 and 2022, and all iPhone 11 to 16 models
• Samsung Galaxy S20 and newer, plus Z Flip and Z Fold
• Google Pixel 3a and newer

What to check
• Your phone must be unlocked and must be a 5G phone (if not using an iPhone)
• For eSIM, dial *#06#. If you see an EID, your phone supports eSIM

It depends on your phone and your preferences:

✅ eSIM (digital SIM):

• Instant delivery: no need to wait for postage

• Easy to install by scanning a QR code

• Great for newer phones that support eSIM (like recent iPhones, Samsung, Pixel)

• No need to remove your UK SIM

✅ Physical SIM (plastic SIM card):

• Ideal if your phone doesn’t support eSIM

• Easy to use: just insert and go

• Requires swapping out your UK SIM while in the USA

Need to call and text back to the UK? 

With the Call & Text Abroad Add-On you get unlimited minutes and texts from the USA (excluding from Alaska) to UK numbers (mobiles and landlines) for the duration of your bundle. You'll also need this Add-On if you want to call UK phones roaming in the USA (they're still a UK number).

You'll also get unlimited minutes and texts from the USA to mobiles and landlines in more than 30 other countries including Canada, Mexico, France, Greece, Ireland and Norway - click here to see the full list.

This add-on only works when you're connected to the T-Mobile network, and won't work when roaming on T-Mobile partner networks in the USA. T-Mobile partner networks provide coverage in remote/rural areas where T-Mobile has no network coverage.

The Call & Text Abroad Add-On can only be purchased with your eSIM/SIM (it can't be added after your eSIM/SIM has been activated, which means you can't buy it when you're already in the USA).

Pricing for this add-on:

5, 7, 10, 14, 21 and 30 Day Bundles: £5.99

45 and 60 Day Bundles: £11.98

90 Day Bndle: £17.97

Want data, calls & texts in Canada and/or Mexico?

If you have the 5 day, 7, 10, 14, 21 or 30 day bundle you get 5GB of 4G data, plus unlimited minutes & texts to the USA, Canada and Mexico, and unlimited minutes & texts to anyone else using our SIM Card who also has this add-on, for the duration of your bundle.

If you have the 45 day bundle you get 5GB valid for days 1-30, then a new 5GB valid for days 31-45. Unused data does not rollover.

If you have the 60 day bundle you get 5GB valid for days 1-30, then a new 5GB valid for days 31-60. Unused data does not rollover.

If you have the 90 day bundle you get 5GB valid for days 1-30, then a new 5GB valid for days 31-60, then a new 5GB valid for days 61-90. Unused data does not rollover.

This is a one-off purchase, so if you use up the 5GB data allowance you can't buy more data for Canada and Mexico.

This add-on must be purchased with your eSIM/SIM. It can't be added later.
