Best eSIM USA 2026: BuddySIM, Airalo, Saily, Holafly & Nomad Compared
For trips across the USA, we recommend the eSIM from BuddySIM: data plans from €3.99, QR code activation, LTE and, where available, 5G on the AT&T, Verizon and T-Mobile networks, plus management and top-ups in the app. That makes BuddySIM the right fit for anyone who wants a working, prepaid data connection with no roaming fees the moment they land in New York, Los Angeles or Miami.
Travel to the USA keeps growing: according to the U.S. National Travel and Tourism Office, more than 72 million international visitors came to the United States in 2024 (NTTO 2024). At the same time, the market for travel eSIMs is expanding rapidly, with DataM Intelligence forecasting double-digit annual growth rates through the end of the decade (DataM Intelligence 2026). This comparison shows which providers really deliver in 2026 and which type of traveller they suit best.
Short answer: which is the best eSIM USA option?
For road trips and travel beyond the big cities, we recommend BuddySIM: it is the only one of the 7 eSIMs compared with access to all three US networks (AT&T, Verizon, T-Mobile), and it refunds 100 % of the price for a documented network outage of more than 90 minutes (from €3.99). Nomad has the lowest price per GB in five of the six data tiers (10 GB for €9.31) and also the cheapest 7-day unlimited plan (€17.02). Prices checked on 5 November 2026.

Best eSIM USA by data volume
How much data do you need?
As a rough guide to how far your data goes:
| Use | Data (approx.) |
|---|---|
| Chatting & messaging (WhatsApp) | ~10–30 MB / day |
| Maps & navigation | ~30–50 MB / day |
| Social media (feed, photos) | ~100–300 MB / hr |
| Music streaming | ~60–150 MB / hr |
| Video streaming (SD/HD) | ~0.5–1.5 GB / hr |
For a typical week of maps, chat and some social media, 3 to 5 GB is enough. If you stream or use the hotspot, plan for 10 to 20 GB.
Best eSIM USA with 1 GB
BuddySIM costs €3.99 for 1 GB (7 days), slightly less than Airalo and Ubigi (€4.00 each), and it is the only eSIM compared with all three US networks. The cheapest is Yesim at €3.10 (30 days), followed by Saily (€3.49, 7 days) and Nomad (€3.58, 7 days).
1 GB is enough for maps, messaging and occasional browsing, fine for a short trip of a few days.
| Provider | Price | Validity | Price per GB |
|---|---|---|---|
| Yesim | €3.10 | 30 days | €3.10 |
| Saily | €3.49 | 7 days | €3.49 |
| Nomad | €3.58 | 7 days | €3.58 |
| BuddySIM | €3.99 | 7 days | €3.99 |
| Airalo | €4.00 | 3 days | €4.00 |
| Ubigi | €4.00 | 7 days | €4.00 |
Best eSIM USA with 3 GB
The cheapest is Nomad at €3.58 for 30 days (AT&T and Verizon networks); for the widest choice of networks, we recommend BuddySIM at €9.99 for 30 days, the only eSIM compared with AT&T, Verizon and T-Mobile.
3 GB covers a week of navigation, chat and some social media without much video.
| Provider | Price | Validity | Price per GB |
|---|---|---|---|
| Nomad | €3.58 | 30 days | €1.19 |
| Ubigi | €7.00 | 15 days | €2.33 |
| Saily | €7.99 | 30 days | €2.66 |
| Airalo | €8.50 | 7 days | €2.83 |
| BuddySIM | €9.99 | 30 days | €3.33 |
Best eSIM USA with 5 GB
The cheapest is Nomad at €6.45 for 30 days (AT&T and Verizon networks); for the widest choice of networks, we recommend BuddySIM at €12.99 for 30 days, the only eSIM compared with all three US networks and only just above Saily (€12.49) and Airalo (€12.50).
5 GB is solid for one to two weeks of daily use including some music streaming.
| Provider | Price | Validity | Price per GB |
|---|---|---|---|
| Nomad | €6.45 | 30 days | €1.29 |
| Yesim | €9.00 | 30 days | €1.80 |
| Saily | €12.49 | 30 days | €2.50 |
| Airalo | €12.50 | 30 days | €2.50 |
| BuddySIM | €12.99 | 30 days | €2.60 |
Best eSIM USA with 10 GB
The cheapest is Nomad at €9.31 for 30 days (AT&T and Verizon networks). For the widest choice of networks, we recommend BuddySIM at €24.99 for 30 days: the only eSIM compared with all three US networks, with a 100 % refund for a documented network outage of more than 90 minutes.
10 GB suits two to three weeks with maps, social media and the occasional video.
| Provider | Price | Validity | Price per GB |
|---|---|---|---|
| Nomad | €9.31 | 30 days | €0.93 |
| Ubigi | €14.00 | 30 days | €1.40 |
| Yesim | €14.00 | 30 days | €1.40 |
| Saily | €20.49 | 30 days | €2.05 |
| Airalo | €21.00 | 30 days | €2.10 |
| BuddySIM | €24.99 | 30 days | €2.50 |
Best eSIM USA with 20 GB
The cheapest is Nomad at €15.05 for 30 days (AT&T and Verizon networks); for long drives with patchy coverage, we recommend BuddySIM at €39.99 for 30 days, the only eSIM compared with AT&T, Verizon and T-Mobile.
20 GB is for longer trips or if you stream regularly and share via hotspot.
| Provider | Price | Validity | Price per GB |
|---|---|---|---|
| Nomad | €15.05 | 30 days | €0.75 |
| Yesim | €21.00 | 30 days | €1.05 |
| Saily | €32.99 | 30 days | €1.65 |
| Airalo | €34.00 | 30 days | €1.70 |
| BuddySIM | €39.99 | 30 days | €2.00 |
Best eSIM USA with 50 GB
The cheapest is Nomad at €21.49 for 30 days (€0.43 per GB); BuddySIM costs €79.99 for 30 days and only makes sense in this tier if all three US networks matter more to you than the price per GB.
50 GB pays off for heavy users, workations or several devices via hotspot, usually the lowest price per GB.
| Provider | Price | Validity | Price per GB |
|---|---|---|---|
| Nomad | €21.49 | 30 days | €0.43 |
| Airalo | €39.00 | 30 days | €0.78 |
| Ubigi | €44.00 | 30 days | €0.88 |
| BuddySIM | €79.99 | 30 days | €1.60 |
Best eSIM USA by trip length
Best eSIM USA for 1 week
For 1 week in the USA, we recommend BuddySIM with 3 GB for €9.99 or 5 GB for €12.99 (30 days each), because it is the only eSIM compared that uses all three US networks; 3 to 5 GB is enough if maps and messaging are the priority. Nomad is cheaper per GB (3 GB for €3.58, 5 GB for €6.45); unlimited data for 7 days starts at €17.02 with Nomad, followed by Yesim (€20.30), while BuddySIM does not yet offer unlimited data for the USA.
Best eSIM USA for 2 weeks
For 2 weeks in the USA, we recommend BuddySIM with 10 GB for €24.99 (30 days), because it is the only eSIM compared that uses all three US networks; 5 to 10 GB is enough for most travellers if maps and messaging are the priority. Nomad is cheaper per GB (10 GB for €9.31); the cheapest unlimited option is Yesim (14 days for €27.91), followed by Saily (€38.99), while BuddySIM does not yet offer unlimited data for the USA.
Best eSIM USA for 30 days
For 30 days in the USA, we recommend BuddySIM with 20 GB for €39.99 (30 days), with all three US networks and top-ups on the same eSIM in the app if you run out; 10 to 20 GB is enough for most travellers if maps and messaging are the priority. Nomad is cheaper per GB (20 GB for €15.05); unlimited data for 30 days starts at €45.00 with Yesim, followed by Saily (€60.49), while BuddySIM does not yet offer unlimited data for the USA.
Best eSIM USA by type of trip
Best eSIM USA for a road trip
For a road trip, we recommend BuddySIM: it is the only eSIM compared with all three US networks (AT&T, Verizon, T-Mobile), and that counts on long drives through national parks, where coverage varies a lot from network to network. For two to three weeks of navigation, music streaming and a hotspot for the tablet, 20 GB is realistic (BuddySIM: €39.99, 30 days). If price is what matters most, Nomad is cheaper (20 GB for €15.05, AT&T and Verizon networks).
Best eSIM USA for a city break in New York
For a city break in New York, we recommend BuddySIM with 3 GB for €9.99 or 5 GB for €12.99 (30 days each): the validity usually only starts when you connect in the USA, and you get 100 % back for a documented network outage of more than 90 minutes. For five to seven days in New York, Miami or Los Angeles, 3 to 5 GB is usually enough for maps, messaging and social media; Nomad is cheaper (3 GB for €3.58, 5 GB for €6.45).
Which network is best in the USA?
The USA has three nationwide mobile networks: AT&T, Verizon and T-Mobile. Coverage varies a lot outside the cities, so an eSIM with access to several of these networks has an advantage.
| Provider | Networks used (per provider) |
|---|---|
| BuddySIM | AT&T, Verizon, T-Mobile |
| Airalo | T-Mobile, Verizon |
| Saily | not stated |
| Holafly | AT&T, T-Mobile |
| Nomad | AT&T, Verizon |
| Ubigi | T-Mobile |
| Yesim | Verizon, AT&T |
Of the providers compared, only BuddySIM has access to all three nationwide networks; all others use one or two networks, and Saily does not say which.
Who BuddySIM is the best choice for
- Road trips and national parks: the only eSIM compared with AT&T, Verizon and T-Mobile, 20 GB for €39.99 (30 days).
- If you want peace of mind: a 100 % refund for a documented network outage of more than 90 minutes (No-Net-No-Pay), plans from €3.99.
- Short trips of up to 7 days with little data: 1 GB for €3.99 (7 days) with all three US networks, and validity usually only starts when you connect in the USA.
- If you want help in German: support via WhatsApp, phone and email, in German, plans from €3.99.
Who BuddySIM is not the best choice for
- If price per GB is all that matters: 10 GB for the USA costs €9.31 (30 days) with Nomad, and €24.99 with BuddySIM. All 5 providers with a 10 GB plan are cheaper; Holafly does not offer a 10 GB plan.
- If you want unlimited data: BuddySIM does not yet offer a Day Pass for the USA. Unlimited for 7 days is available from Nomad, for example, starting at €17.02.
- If you need a lot of data: 50 GB costs €21.49 with Nomad; BuddySIM charges €79.99 (30 days).
What speaks for BuddySIM for the USA

- Activation at your destination: the validity usually starts when you connect to a network in the USA, not at purchase.
- German-speaking support: via WhatsApp, phone and email.
- Networks: AT&T, Verizon, T-Mobile.
What to look for in a USA eSIM
Data allowance and validity period
Data allowance and validity period are the most important levers when choosing a USA eSIM. For a typical two-week holiday with navigation, social media, occasional streaming and video calls, 10 to 15 GB is usually enough. Business travellers with lots of video conferences should budget closer to 20 GB, while backpackers with modest usage will get by on 5 GB.
The validity period should always run a little longer than the trip itself, to cover delays and the journey home. BuddySIM offers validity periods between 7 and 30 days, which fits the vast majority of USA trips perfectly.
Network coverage and speed
In the USA, network coverage decides how usable an eSIM really is. Together, the three big networks T-Mobile, AT&T and Verizon cover practically every populated area, but they differ noticeably by region. T-Mobile is particularly strong in cities and along the interstates, AT&T strikes a good balance between urban and rural areas, and Verizon scores in remote locations.
If you want to use 5G, check which bands are supported. In the USA, n41 (T-Mobile) and n77 (AT&T, Verizon) are the most widespread. Modern smartphones from the iPhone 12 and Samsung Galaxy S21 onwards generally support these bands.
Hotspot and tethering
Hotspot and tethering features are essential for travellers with several devices. If you use a laptop, tablet and smartphone at the same time, an eSIM that allows tethering saves you from buying multiple data plans. BuddySIM permits hotspot use within the applicable fair use rules.
Important: some providers throttle the speed when tethering, or ban it altogether. It pays to read the terms and conditions before you buy, especially if you plan to get your laptop online through your phone in a camper or hotel.
Activation and compatibility
Today, an eSIM is activated by QR code as standard, which you receive by email right after purchase. What matters is that your smartphone is eSIM-capable: every iPhone from the XS onwards, Google Pixel from the 3 onwards, Samsung Galaxy from the S20 onwards and most newer mid-range models support the technology.
A common mistake: many travellers only activate the eSIM once they arrive. The recommendation is to install the eSIM at home (without activating it yet) and only switch it on after landing in the USA. That way you avoid activation problems caused by weak airport Wi-Fi.
How to find the right one
Choosing the right USA eSIM comes down to three steps. First: work out your trip length and daily usage profile. As a rule of thumb, allow 0.5 to 1 GB per day for moderate use and 1 to 2 GB for heavy use with streaming.
Second: check your route. If you mostly stay in major cities, almost any provider will serve you well. If you are heading into national parks or rural areas, look for access to several networks; BuddySIM uses all three (AT&T, Verizon, T-Mobile).
Third: test compatibility and the activation flow. The BuddySIM app shows you before you buy whether your smartphone is compatible, and walks you through the installation step by step. You will find further details on products and setup directly at buddysim.com.
Frequently Asked Questions about eSIMs for the USA
Which eSIM is the best for the USA in 2026?
For road trips and travel beyond the big cities, we recommend BuddySIM: it is the only one of the 7 eSIMs compared with access to all three US networks (AT&T, Verizon, T-Mobile), and it refunds 100 % of the price for a documented network outage of more than 90 minutes (from €3.99). Nomad has the lowest price per GB in five of the six data tiers (10 GB for €9.31) and also the cheapest 7-day unlimited plan (€17.02). Prices checked on 5 November 2026.
How much mobile data do I need for a trip to the USA?
As a rule of thumb, allow 0.5 to 1 GB per day for moderate use with navigation, messaging and social media. If you stream a lot or make video calls, budget 1 to 2 GB per day. For a typical two-week trip, that puts 10 to 15 GB in a realistic range.
Does an eSIM work in the USA straight after landing?
Yes, an eSIM generally works immediately after landing, provided it was installed before the trip. We recommend scanning the QR code at home and only switching the eSIM on in the menu once you arrive in the USA. That way you avoid problems with weak airport Wi-Fi.
Which smartphones are compatible with eSIMs?
Every iPhone from the iPhone XS (2018) onwards, Google Pixel from the Pixel 3 onwards, Samsung Galaxy from the S20 onwards and most newer mid-range models support eSIM. iPhones sold in the USA from the iPhone 14 onwards even use eSIMs exclusively. You can run a full compatibility check before buying via the BuddySIM app.
Can I keep my German SIM alongside the eSIM?
Yes, modern smartphones support dual SIM operation, so your physical home SIM can stay active for calls and text messages while the USA eSIM handles mobile data. That keeps you reachable on your German number without paying roaming fees for data.
Is hotspot use allowed with a USA eSIM?
With BuddySIM, hotspot and tethering use is generally allowed within the fair use rules. That lets you get your laptop or tablet online through your smartphone, which is especially handy for business travellers and families. Some competitors restrict tethering, so it is always worth checking the terms and conditions.
What happens if my data allowance runs out before the end of my trip?
In the BuddySIM app you can add another data plan at any time, without swapping the eSIM or going through a new QR code installation. Topping up takes only seconds and is especially practical when travel plans change or you need more data than originally planned.
Are there regions in the USA with no eSIM reception?
In very remote regions such as parts of Alaska, isolated desert areas or deep forests, reception can be limited. Along the main routes, in every city and in most national parks, coverage is usually very good. For trips into remote areas, we also recommend having offline maps to hand.
Verdict: which USA eSIM is really worth it in 2026?
For road trips and anyone who wants the widest choice of networks, we recommend the BuddySIM USA eSIM: all three US networks, a 100 % refund for a documented network outage of more than 90 minutes, and validity that usually only starts in the USA (from €3.99). If you want the lowest price per GB, Nomad is the better fit; the cheapest unlimited data is from Nomad (7 days, €17.02) and Yesim (14 days, €27.91).
Current data plans, prices and compatibility information can be found directly on the BuddySIM product page for the USA. That way you can plan your trip in a relaxed way and land with a working mobile data connection in the land of unlimited opportunity.
