What is eSIM? Can I use eSIM?: learn more
With eSIM it's much quicker to get set up because there's no physical SIM sent in the post. eSIM is compatible with most new phones, and setting up eSIM is as simple as scanning a QR code with your phone's camera.
→ eSIM is a digital SIM card that’s already built into the electronics of many newer model phones including iPhone XS, XR, 11, 12, 13, 14, 15, 16 and Samsung Galaxy S20 5G, S21, S22, S23, S24, S25 + many other phones.
→ With our eSIMs you get a USA phone number and you can receive & make phone calls in the USA. Most other eSIMs are data only which means no phone number and no calls! Our eSIM is different to the others because it's directly with the USA mobile network carrier.
→ You simply scan a QR code with your phone's camera to install the eSIM, which means you don't need to find a paperclip to remove your existing SIM Card and insert a new SIM Card.
→ No waiting for your SIM Card in the post. Instead of having to wait for your physical SIM to be delivered, you can get connected immediately.
→ Our USA eSIM works exactly like a physical USA SIM (you still get a real USA phone number and you can make calls and sends SMS texts), but it makes setting up your bundle a breeze.
→ It doesn't matter if you're already using a UK eSIM from your telco provider. Your phone can install multiple eSIMs (you DO NOT NEED to delete your UK eSIM and the USA eSIM DOES NOT affect or disrupt your UK eSIM).
→ With eSIM you get dual SIM functionality: this means you can have 2 numbers on the one phone (your UK number & your new USA number).
→ Most new phones support eSIM. See the full list below.
Already using an eSIM from EE, O2, Vodafone or Three?
No problem! Our USA eSIM works alongside your existing eSIM. You don't need to delete your UK eSIM. You don't even need to tell your telco you're using another eSIM.
Keep your UK number when you're in the USA
With eSIM you can keep using your UK number when you're in the USA. Because you don't need to remove your UK SIM Card/eSIM from your phone, you can keep it turned on, alongside your USA eSIM. Think of it like having a "dual SIM" phone. (You'll need to have international roaming enabled on your UK SIM Card for it to work in the USA to receive calls/texts to your UK number).
This is perfect for receiving important calls or texts (such as one-time passwords from your bank). Or if you want you can remove your UK physical SIM Card or turn off your UK eSIM for the duration of your trip.
You get exactly the same thing as if you had a physical USA SIM Card
With our USA eSIM you get exactly the same thing as if you had a physical USA SIM Card: you still get a USA phone number, you can still make and receive calls, you can still send and receive texts, you can still use 5G/4G data, and you can still use any add-ons.
Other eSIM providers limit you to data use only (no phone number, so no calls or texts). With our USA eSIM you still get a USA phone number and that's important for things like government forms, tour operators, your Uber app, etc.
eSIM is super easy to activate!
Don't worry you don't need a PhD in mobile phones to use eSIM! If you can open the Settings App on your phone, then you can use eSIM.
After you place an eSIM order, check your order confirmation email and reply to it with your phone's EID number (that's the serial number of your phone's eSIM found in your Settings), your phone's eSIM IMEI (also found in your Settings), and the date you want your eSIM to start working.
Your eSIM will then be activated by 6am US Pacific Time on the date you request.
If you have an iPhone then you'll get a notification on your iPhone to install the eSIM. Tap yes, and your eSIM will get set up in a few minutes. If you have a Samsung, Huawei, Oppo, Pixel or other phone, you'll either get a notification on your phone to install the eSIM (just tap it to install) or you'll scan a QR code, and your eSIM will get set up in a few minutes.
eSIM is better for the environment
There’s no packaging, no plastic, and no petrol used to transport your letter in the post to you.

Physical SIM or eSIM
You can choose a physical SIM Card, or you can choose an eSIM if you have iPhone XS, XR, 11, 12, 13, 14, 15 or 16, Samsung S20, S21, S22, S23, S24, Z Fold, Z Flip, Google Pixel 4a onwards, plus other phones. What’s eSIM? Read FAQ below “What is eSIM?”.
Our physical SIM Card is a Trio SIM that adapts to all sizes: nano, micro or standard.
Our eSIMs are better!
Our T-Mobile eSIM is directly with T-Mobile USA. It’s NOT through a third party reseller or virtual mobile network operator.
Why is this important? It means you’re getting the exact same eSIM that you’d get directly from T-Mobile if you went into a T-Mobile store in the USA.
Some other eSIMs are sold through third part reseller or virtual mobile network operators and that means you might get inferior network coverage or slower/capped data speeds.
5G at no extra cost
You get 5G at no extra cost. All 10GB data is at the fastest uncapped 5G speed.
On the T-Mobile network
Our physical Trio SIMs and eSIMs are direct with T-Mobile, not through a reseller or virtual network provider. This means you get the full T-Mobile network coverage.
Also, other eSIMs for the USA don’t include a USA phone number. Our eSIM does have a regular USA phone number, just like if you had a physical SIM.
You get a USA mobile number

Optional add-ons
Call/Text Abroad Add-On: learn more
Need to call and text back to the UK?
With this Add-On you get unlimited minutes and texts from the USA (excluding Alaska) to UK numbers (mobiles and landlines) for the duration of your bundle. This Add-On does not work when you’re in Alaska. You’ll also need this Add-On if you want to call UK phones being used in the USA (because you’ll still be calling a UK mobile 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.
Pricing for this add-on:
5, 7, 10, 14, 21 and 30 Day Bundles: £7.99 (costs £15.98 if you want to buy the add-on after SIM Card/eSIM has been activated)
45 and 60 Day Bundles: £15.98 (costs £31.96 if you want to buy the add-on after SIM Card/eSIM has been activated)
90 Day Bndle: £23.97 (costs £47.94 if you want to buy the add-on after SIM Card/eSIM has been activated)
Canada/Mexico Add-On: learn more
Need to use your phone in Canada and/or Mexico?
With this Add-On 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. With the 60 day bundle you’ll get 5GB valid for day 1-30, then a new 5GB valid for day 31-60. With the 90 day bundle you’ll get 5GB valid for day 1-30, then a new 5GB valid for day 31-60, then a new 5GB valid for day 61-90.
This is a one-off purchase, so if you use up the 5GB you can’t buy more data for Canada and Mexico.
Cost of this add-on:
5, 7, 10, 14, 21 and 30 Day Bundles: £4.99 (£9.98 if you want to buy it after your SIM Card/eSIM has been activated)

How do I install my eSIM?
Setting up your eSIM is simple, easier than a physical SIM. You do not need to remove your UK SIM or swap anything.
After you order, we email clear setup steps. Install takes about a minute. When you land in the USA, turn the eSIM line on. It connects quickly. No SIM tool. No shop visit.
Perfect for UK travellers. You are online as you arrive.
How quickly will I receive my eSIM?
Travelling soon and need a USA eSIM fast? Most orders are issued within a few hours. Often faster. Place your order and check your confirmation email. We handle the rest and send your setup details. You are ready to go.
Can I buy now and activate my USA eSIM or SIM later?
Yes. We recommend it. Order as early as you like. Activation does not start at purchase. Your bundle begins on the date you choose during activation. Turn it on when you land in the USA, or on the day that suits your trip. Buy early and stay organised. Your eSIM or SIM will be ready when you are.
Will my apps, contacts, and photos change with a USA eSIM or SIM?
No. Your phone stores your photos, contacts, apps, emails, and settings. Not the SIM.
Adding a USA eSIM or inserting a USA SIM will not delete or change anything.
Install the USA eSIM or insert the USA SIM when you travel. Everything stays the same. When you return, put your UK SIM back in and carry on.

For a physical SIM
• iPhone 8 and newer

What to check
• Your phone must be unlocked
• For eSIM, dial *#06#. If you see an EID, your phone supports eSIM
Will my eSIM or SIM work in Hawaii and Alaska?
Yes. Hawaii is covered on our USA SIMs and eSIMs. You will get service across the main islands and most built up areas. Remote valleys and high ridges may have limited or no signal.
Alaska is not included in coverage on the T-Mobile network, so our SIM/eSIM won't work in Alaska.
Can I use my USA SIM or eSIM in Canada or Mexico?
Yes. Pick the optional Canada and Mexico add on. With this add on you can use your SIM or eSIM while travelling in Canada and Mexico. You get unlimited calls and texts to the USA, Canada, and Mexico. You also get 5 GB of 4G data per 30 day period, depending on your plan. Choose the add on at checkout. It cannot be added later. See your plan page for details and pricing.
How good is mobile coverage in the USA?
Our USA SIMs and eSIMs use the T-Mobile network. 4G and 5G cover most cities, towns, and highways.
Notes
• Alaska is not included.
• T-Mobile maps show outdoor coverage only and are a guide.
• If an area shows Partner coverage, service may be limited or unavailable.
Coverage can vary with
• Terrain and elevation
• Weather
• Buildings and obstructions
• Signal strength and your phone model
Check the T-Mobile Coverage Map with the exact address or ZIP code of where you will stay before you buy. If an area shows Partner coverage, service may be limited or unavailable.
Are your USA SIMs and eSIMs from real networks or resellers?
Our USA SIMs and eSIMs come direct from T-Mobile, a major US network. We do not sell MVNO reseller products.
What this means for you
• Full network access where T-Mobile operates
• Better prioritisation at busy times
• Wider feature support and reliable speeds
What is an MVNO?
In the UK, brands like giffgaff, Tesco Mobile, Lebara, and VOXI run on EE, O2, Vodafone, or Three. Good value, but they may have lower priority or limited features. The same model exists in the USA with brands that ride on major networks.
With us you get a genuine T-Mobile product. Expect strong coverage across mainland USA. Check the coverage map for your destinations.
Can I use this SIM or eSIM in the UK as well?
No. Our USA SIMs and eSIMs only work in the United States. With the Canada and Mexico add on, they also work there. They do not roam in the UK. They will not connect to UK networks before you fly. They cannot receive verification codes while you are in the UK. Activate and use the number once you arrive in the USA.
Does my phone need to be unlocked for a USA eSIM or SIM?
Yes. Your phone must be network unlocked to use our USA eSIM or SIM. Most UK phones are unlocked, but check first.
iPhone
• Settings > General > About
• Find Network Provider Lock
• If it says No SIM restrictions, your iPhone is unlocked
Android and other phones
• Insert a SIM from a different network, for example EE if you are on O2
• Restart the phone
• If the new network name appears, it is unlocked
• If you see Invalid SIM or SIM network unlock PIN, it is locked
If it is locked
• Contact your network, for example EE, O2, Vodafone, or Three
• Ask for a network unlock
• Do this before you fly, it can take time
Notes
• We cannot unlock phones
• Dual SIM or eSIM does not bypass a network lock
5G and 4G Data, Speeds and Usage
Is the data really unlimited?
Yes. Our T-Mobile Bundles include unlimited data. Stream, browse, maps, and hotspot across the USA without running out.
Network management
• After 50 GB in a 30 day period, T-Mobile may prioritise other users at busy times.
• Speeds can slow in crowded areas.
• Your data continues. It is not capped or cut off.
What mobile data speeds should I expect in the USA?
Our T-Mobile Bundles have no plan speed cap. T-Mobile do not throttle speeds. 5G and 4G speeds depend on signal and congestion. With strong 5G you can see several hundred Mbps or more. After 50 GB in a 30 day period, T-Mobile may prioritise other users at busy times. Your data continues.
Real world tests on our SIMs and eSIMs
• 589 Mbps down, 56 Mbps up. iPhone 12. Chicago. 18 Nov 2022. See it here.
• 916 Mbps down, 92 Mbps up. iPhone 13 Pro Max. Los Angeles. 17 Mar 2023. See it here.
• 189 Mbps down, 85 Mbps up. Google Pixel 6a. Los Angeles. 17 Mar 2023. See it here.
Results vary by phone, band, and location. Indoor speeds are often lower than outdoors.
Can I use my phone as a hotspot/tether with this SIM or eSIM?
Yes. You can share your data with laptops, tablets, and other devices.
T-Mobile Unlimited Bundle
• Hotspot is included. Connected devices run at about 3G speeds.
• For faster hotspot, choose the 30 day bundle with 5 GB of 5G or 4G hotspot data. After 5 GB, hotspot returns to 3G speeds.
T-Mobile 10 GB Bundle
• Use your full 10 GB at 5G or 4G hotspot speeds.
Good for UK travellers on work trips, road trips, and navigation on a tablet.
Can I top up my bundle if I am staying longer?
Yes. You have two options.
Option 1. Top-up your existing eSIM or SIM on our website. Each top-up adds 30 days. Top-ups are only sold in 30 day blocks. If your return date is unclear, choose a longer bundle to avoid gaps.
Option 2. Buy a new T-Mobile eSIM. Choose 5, 7, 10, 14, 21, 30, 45, 60, or 90 days. Each new eSIM includes a new US number. You cannot move your old number to a new eSIM.
Can I reuse my SIM or eSIM for another trip?
No. You'll need to buy a new SIM/eSIM. Anyway, it's cheaper to buy new than top-up.
When does my 30 day SIM or eSIM bundle start?
Your bundle only starts on the activation date you choose, not the purchase date.
Physical SIM
• Follow the instructions in your delivery.
• Open the online activation form and pick your USA start date.
• That date is Day 1 of your bundle.
eSIM
