Why Travellers Love Using eSIMs in the USA

Having an American eSIM isn't just about practicality.

The assurance of having your phone, and therefore any info you need at the push of a button, can seriously enhance your time abroad.

And travellers rave about eSIMs for USA because they solve so many on-the-road problems.

Here are some real-life scenarios where a USA eSIM comes to the rescue.

Why Choosing the Best eSIM for USA Matters

You might be thinking, "any internet is fine, right?"

But trust me, the quality of your connection can make or break your trip to the USA.

Imagine your roaming fails right when you need to show your concert e-ticket.

Or staring at a loading screen when you need an Uber at 1am.

And let's not forget roaming charges. If you stick with your UK SIM card in the USA without setting up an add-on plan in advance, you could rack up eye-watering fees.

Think £6 per MB on some networks, which is around £6,000 per 1GB. Ouch.

A good travel eSIM for USA spares you that nightmare, offering a local data connection at a fraction of the cost.

Picking the right eSIM is part of using tech to travel smarter.

It's like choosing a reliable car for a road trip. You want something that won't break down when you need it most.

What You'll Need Mobile Data For in the USA

In the USA, you'll find you need mobile data for far more than just Googling the best pizza joint in town.

Must-Have Apps in the USA

Download these apps over Wi-Fi before you leave to navigate the USA like a pro.

• Uber and Lyft - Google Play | Apple: These ride-hailing apps are the standard in most American cities, offering a convenient way to get around without a car.
• Yelp - Google Play | Apple: The go-to app for finding and reviewing restaurants, cafes, bars, and other local businesses. Essential for foodies and those looking for reliable local recommendations.
• Google Maps - Google Play | Apple: The best app for navigation, offering detailed directions for driving, walking, and public transport in cities like New York, Chicago, and San Francisco.
• DoorDash and Grubhub - Google Play | Apple: These are popular food delivery apps, perfect for when you want to order in from a local restaurant.
• Transit - Google Play | Apple: A fantastic app for navigating public transport in major US cities, providing real-time schedules and route planning.
• Venmo - Google Play | Apple: While you may not be able to set up an account without a US bank, this is the most common payment app for splitting bills with friends. It's useful to know what it is and how to use it if you're travelling with US friends.

Now we've covered why having a quality connection matters, let's talk specifics about getting online in the USA.

Things You Should Know About Getting Online in the USA

Mobile Network Speeds and Coverage

What's Internet Coverage Like in the USA?

The USA has extensive mobile coverage, especially in big cities. The country is well-connected and a USA eSIM can tap into those local networks seamlessly.

All three major operators - Verizon, AT&T, and T-Mobile - provide 4G LTE and 5G across the country, with widespread coverage in major urban and suburban areas.

If you stick to cities and popular destinations such as New York, Los Angeles, Chicago, and Orlando, you'll likely have a strong 4G or 5G signal.

Overall, expect solid coverage in most populated areas, with patchy service in remote, rural regions or national parks.

Will You Get Fast Internet Speeds in the USA?

Yes, you can get fast mobile internet in the USA. On 4G LTE and 5G networks, download speeds of 30 - 150 Mbps are common on a good network.

Which is plenty for streaming Netflix or making video calls.

Upload speeds are typically lower; perhaps 10 - 50 Mbps. But that's fine for posting your travel photos or making a video call.

Can You Get 5G in the USA?

Yes, absolutely. The USA was one of the first countries to roll out 5G, and it is now available in most major cities and many smaller towns.

The 5G network is rapidly expanding, and you'll often see the 5G symbol on your phone in urban areas. This makes an eSIM USA even more powerful.

Even in areas where 5G isn't available, the USA's 4G LTE network is reliable and fast, offering a seamless experience for typical travel needs.

What Are 3G Speeds Like In the USA?

On 3G, speeds will drop significantly to a few Mbps at best.

Which is enough for WhatsApp and emails. But you'll feel the sluggishness if you try loading big webpages or videos.

Thankfully, you'll only fall back to 3G in more remote places.

In cities and large towns, 5G and 4G are the norm and offer a smooth internet experience.

For typical travel needs, map and taxi apps, watching videos or streaming music and podcasts, you won't have problems.

Even video calling apps should work well on 4G in the USA.

Just avoid video calls in crowded spots where everyone's on the network. Like anywhere, it can get congested.

Local Laws and Mobile Network Rules In the USA

When getting connected in the USA, there are a few local rules and regulations to keep in mind.

Passport Registration When Buying Local SIM Cards

If you decide to buy a physical US SIM card, you will not need your passport. There are no national laws requiring ID registration for prepaid SIM cards. However, some individual stores may ask for an ID for age verification, but it is not a legal requirement for activation.

Compatibility with UK Phones

Most modern phones from the UK and Ireland are compatible with US networks. However, some older models might not support the specific frequency bands used by US carriers. This is becoming less of an issue with newer, multi-band smartphones. An American eSIM bypasses this problem as it automatically connects to a supported network.

The USA is Outside of EU Roaming

Unlike trips to Spain or France, where some UK plans still offer free EU roaming, the USA is not part of the EU or EEA.

That means your UK network will likely charge you extra for using data, calls, or texts in the USA.

Some carriers charge up to £7 per day for limited data via a roaming pass. Others might bill you per MB unless you buy a specific add-on in advance.

In short, you could rack up a hefty bill fast, even from background app activity.

Avoid this risk by switching off mobile data unless you're on Wi-Fi. And by picking up a local SIM card or using a travel eSIM and topping it up as you go.

In summary, getting online in the USA is fairly straightforward.

• You won't need a passport to register for most data-only eSIMs or SIMs for tourists.
• Know that your bank account won't thank you if you roam here without a plan.

Can I Use a VPN in the USA?

Yes, Virtual Private Networks (VPNs) are widely used in the USA and aren't illegal for personal use. Many locals and expats install VPNs to:

• Access geo-restricted content from their home countries (e.g., BBC iPlayer).
• Browse privately and securely, especially on public Wi-Fi.
• Avoid content throttling.

Travel eSIMs vs Local SIM Card - What's Better for the USA?

Two of the most practical ways to get online in the USA are to buy a travel eSIM or buy a local physical SIM card.

Both have their pros and cons and the best eSIM for USA choice depends on your situation.

Here's an at-a-glance comparison between them.

Why Choose a SIM Card for the USA?

Physical US SIM cards are easy to find at airports and phone shops.

You'll not need to register with your passport for a prepaid SIM card, making the process quick.

Local tourist packages often come with generous data allowances. Useful if you're a heavy data user or staying for months, rather than days.

Plastic SIM cards are ideal for: Those who need a local phone number while in the USA, rely on traditional calls and messaging and don't mind researching SIM cards, visiting physical stores and filling in paperwork. Digital nomads, people planning to stream a lot or travel slowly over several weeks.

Why Choose an eSIM for the USA?

eSIMs are digital SIMs already embedded into your phone.

That means no researching the best SIM cards for the USA, no hunting for and queuing at SIM card shops, no paperwork and no swapping SIM cards in and out of your phone.

You install your eSIM before you even leave the UK, usually via an app or QR code.

Using your eSIM for USA data and your UK SIM card for calls and texts allows you to stay contactable and online throughout your trip.

If you're travelling with family or groups and using your phone as a Wi-Fi hotspot, providers such as Airalo allow you to hotspot with few or no restrictions.

Speed-wise, some providers, such as Airalo do not throttle your connection on their standard plans as you reach your data limit.

eSIMs for USA are ideal for: Regular and short-stay holidays in the USA, solo travellers, business travellers, families hotspotting off one device, travellers hopping between countries, making short-notice travel decisions or those who don't want to spend time looking for SIM cards and completing paperwork.

Example Use Cases

To make this all more concrete, here are a few typical traveller profiles and what eSIM plan might suit them best in the USA.

City Breaker
Trip: 5 days in New York City.
Data Needed: Around 3 GB, maybe slightly more.
Use: Google Maps, uploading Instagram Stories, Googling museums and restaurants, WhatsApp calls to family, streaming Netflix at the hotel.
Suggested Plan: eSIMs for USA would include a 5 GB plan - gives enough wiggle room and covers your whole trip.

Family Holiday
Trip: 10 days in Orlando.
Data Needed: Between 10 and 20 GB total, depending on usage.
Use: Parents using maps and park apps, kids watching YouTube or Netflix and gaming, hotspotting for tablets, uploading daily pics.
Suggested Plan: For peace of mind, a 10-day unlimited USA eSIM plan might be a good option, along with using Wi-Fi. Or multiple smaller plans, such as 3GB or 5GB eSIMs for each family member.

Road Tripper
Trip: 2 weeks split between California and Nevada.
Data Needed: Between 5 and 6 GB.
Use: Streaming Spotify or podcasts on the road, navigation, occasional video calls home, social uploads.
Suggested Plan: A 10 GB / 30-day American eSIM - enough to relax without rationing data, especially on long stretches between cities.

Digital Nomad
Trip: 1 month working remotely from the USA.
Data Needed: 20 to 30 GB.
Use: Daily Zoom calls, hotspotting laptop, managing work tools, constant web access, plus Netflix and YouTube in downtime.
Suggested Plan: A 20 GB / 30-day eSIM for the USA. Top up as needed mid-month and use café/co-working Wi-Fi to save mobile data.

Can You Rely Only On Wi-Fi in the USA?

Sort of, but only if you're very disciplined and not too fussed about staying connected 24/7.

Many hotels, cafes and airports offer free Wi-Fi, but it's not always fast or secure.

And unless you're using a VPN, it's best to avoid logging into sensitive apps on public networks.

If you go Wi-Fi-only, you'll need to switch off mobile data entirely to avoid accidental charges.

Even background apps like WhatsApp, email or cloud backups can quietly eat data in the background.

Ideal for: Ultra-light users, digital detoxers and travellers happy to be offline most of the time. If you only need to check messages once or twice a day and internet access isn't crucial to your trip, it can work.

Is Roaming in the USA Worth It?

Usually not. Since the USA isn't in the EU roaming zone, your UK mobile provider will treat it as an international destination. And that gets very expensive, very quickly.

Without a roaming pass, you'll be on pay-as-you-go rates. A typical example for UK mobile users is £6 per MB.

That won't stretch far; maybe a few minutes of Google Maps or a single app update. And it works out to around £6,000 per GB. Nope, that's not a typo.

Other UK networks offer daily roaming passes, such as £7 per day for limited data.

Even with the latter better deal, that's still £98 over two weeks.

In contrast, a 5GB USA eSIMs plan over 30 days from Airalo costs around £10. That's a 90% saving compared to £98 over two weeks.

Ideal for: Only in emergencies or for short trips. Also, check if your plan includes the USA, as many don't. Check for fair use caps and automatic activation, as daily roaming passes often activate the moment your phone uses any data abroad, even in the background.

The bottom line? Free Wi-Fi isn't the most reliable. The signal can drop, speeds can crawl and you might need SMS verification - tricky if your UK SIM isn't working. Roaming is expensive and you never know when you'll suddenly need to be online for longer.

If you want to use your phone freely without a nasty bill surprise, grab a local SIM card or a travel eSIM - your bank balance will thank you.

How to Choose the Best eSIM for USA

Step 1 - Check Your Phone Is eSIM-Compatible

First things first: does your phone support eSIMs?

Generally, if your phone was released in 2018 or later, it's likely to be eSIM-compatible.

This includes iPhones from the XR/XS onward, Google Pixel 3 and later, Samsung Galaxy S20 series, newer, recent Huawei and Oppo models and many others.

To check if your phone is eSIM-compatible, do the following:

1. Search your phone model and "eSIM" online: "Does [your phone model] support eSIM?". The manufacturer's site or specs sheet should confirm it.
2. Dial #06# on your phone: On many devices, this reveals your phone's identifiers. If you see an EID number listed (which stands for Embedded Identity Document), your phone has eSIM capability.
3. Check your phone's settings: Go to Settings > Mobile Data > Add Data Plan or Connections > SIM Card Manager. If you see an option to add a plan or scan a QR code, you're eSIM ready.

If your phone does not support eSIMs, you may have to source a physical local SIM for the USA or a roaming bolt-on.

But assuming you're good to go, let's move on to the next step.

Step 2 - Understand Your Data Needs

Think about these factors to understand how many GB you'll need for the USA, for how long and in which areas.

• How Long Do You Need Your USA eSIM For? Will you be in the USA for a weekend or a month? Make sure your eSIM plan lasts your whole trip and that you can top up easily if you need to. Some eSIMs expire after 7, 15 or 30 days.

• Where Will You Be Using Your eSIM? If you're visiting more than one country or territory on your trip, a regional or global eSIM might offer better value than buying separate ones for each stop.

• How Much Data Will You Need? Light users might rely on maps, messaging and light browsing, while heavy users may plan to stream, hotspot, game or work remotely. This is the key to finding the best eSIM for USA.

• Do You Need Your eSIM for Hotspots and Tethering? If you have family, kids, laptop, tablets or travel buddies in tow, you might need to use your device as a hotspot. Some eSIM providers, such as Airalo, allow hotspotting, while others don't. Hotspotting will drain your allowance and battery faster, so take these things into account when deciding on your data needs.

Step 3 - Make Sure You'll Get Value From Your Chosen eSIM

When it comes to buying data for travelling, value is about more than just price.

Consider Customer Service

Before you decide on an eSIM provider, check that they prioritise good customer service. How well do others rate their services? If you're in a tight spot, access to fast and reliable troubleshooting is everything.

Can You Top Up Easily If You Run Out of Data?

No one wants to be stranded without data trying to access a top-up page that won't load. Look for eSIMs that let you top up in-app, on the go, with clear pricing and no hidden fees.

Is It Easy to Track Your Usage?

You should be able to check your remaining data in real time and/or through an app. If you're worried about running out, pick one with smart notifications or usage alerts.

How to Install An eSIM For the USA

Once you've chosen the best eSIM for USA for your trip and needs, installing it is as easy as ordering food.

In fact, it might even be ready faster than your burger. Using Airalo as an example, follow these steps to get started.

1.) Download the Airalo app, available on iOS and Android or visit the Airalo website.

3.) At the checkout, apply the voucher code USABEST15 for 15% off your first USA eSIM (more on that in a second).
