Which eSIM fits your trip?
🏙️ City trip (NYC, LA, Miami)
For a short trip to New York, Los Angeles or Miami, 3-5 GB are completely sufficient. You use Google Maps, WhatsApp, Uber and post on Instagram - this consumes around 500 MB per day. WLAN is also available in most hotels and cafés.
Recommendation: Airalo 3 GB (7 days) or Nomad 5 GB - cheap and sufficient.
🚗 Road trip (Route 66, West Coast, National Parks)
On a road trip, you rely on navigation and use more data than in the city. Google Maps alone uses approx. 50-100 MB per hour. In national parks such as Yosemite or the Grand Canyon, reception is limited - download maps offline beforehand.
Recommendation: Holafly Unlimited - no data stress on the move, even with intensive use.
💼 Business & Remote Work
Are you working remotely from the USA? Then you need a stable connection for video calls (Zoom uses approx. 1 GB/hour) and a hotspot function for your laptop. Unlimited data is mandatory here.
Recommendation: Holafly Unlimited with hotspot or Airalo 20 GB for shorter stays.
Practical info for USA
Does eSIM work immediately after landing?
Yes - with Airalo, Holafly and Nomad, your eSIM connects automatically as soon as you activate data roaming at the airport (e.g. JFK, LAX or SFO). The connection is usually established within 1-2 minutes. Tip: Install eSIM before departure so that you only have to activate it after landing.
How good is the network coverage in the USA?
In large cities such as New York, Los Angeles, Chicago or Miami, coverage over T-Mobile and AT&T is excellent - usually with 4G/LTE, sometimes even 5G. In rural areas, e.g. on road trips through Nevada, Montana or along the Route 66, coverage can be patchy. In national parks such as Yellowstone, Yosemite or the Grand Canyon there is often only limited reception. For road trips, we recommend providers that use the T-Mobile network, as it offers broader rural coverage.
Is 5 GB enough or would you prefer Unlimited?
That depends on your usage behavior. 5 GB is enough for approx. 7 days of normal surfing: Google maps, WhatsApp, emails and occasional social media. If you post Instagram stories every day, stream Spotify or use Google maps in road trip mode, you will quickly use 1-2 GB per day. For trips over a week or frequent users, Unlimited is the stress-free choice.
Do I need a local US phone number?
Not for most travelers. You can be reached via WhatsApp, FaceTime, Zoom and co. even without a US number. However, a local number can be useful if you want to use US services that require verification via SMS (e.g. Uber registration or local booking portals).
Is hotspot/tethering possible?
Yes, but not with all providers. Holafly supports hotspot with most Unlimited tariffs. Airalo offers tethering on selected packages. Check this before you buy - especially if you want to connect your laptop or a second device via your smartphone.
Typical data consumption on USA vacation
Google Maps Navigation: approx. 50-100 MB per hour. Instagram/TikTok: approx. 500 MB-1 GB per hour. WhatsApp video call: approx. 300 MB per hour. Spotify streaming: approx. 70 MB per hour. For a typical vacation day with navigation, messaging and social media, you can expect 500 MB to 1 GB.

Frequently asked questions
Everything you need to know about eSIM in USA.
Which eSIM is the best for USA?
Airalo offers the best overall performance: great network coverage via T-Mobile, intuitive app and fast activation. For travelers who stream a lot or are on road trips, Holafly with Unlimited data is the better choice. Budget travelers fare well with Nomad - it often offers the cheapest packages from €5.
Does eSIM work in the USA immediately after landing?
Yes, with most providers (Airalo, Holafly, Nomad), the eSIM connects automatically as soon as you activate data roaming at the airport. Ideally, you should install the eSIM before your departure - this way you only have to go to the settings after landing and activate the eSIM as your data tariff. The connection is usually established within 1-2 minutes.
Is eSIM cheaper than roaming in USA?
Clearly. German mobile phone providers often charge €5-12 per MB for USA roaming. A eSIM with 5 GB, on the other hand, costs just €4.50-8. On a typical one-week vacation, you can easily save €50-100 with a eSIM compared to classic roaming.
How much data volume do I need in the USA?
For a one-week city trip (New York, LA) with navigation, WhatsApp and occasional social media, 3-5 GB is sufficient. For a two-week road trip with daily navigation and streaming, we recommend 10 GB+ or Unlimited. Frequent users (remote work, video calls, hotspot) should go straight for Unlimited.
Can I continue to use WhatsApp and FaceTime as normal?
Yes, without restrictions. WhatsApp, FaceTime, Zoom and other messengers work as usual via the eSIM data connection. Your German number remains active on the physical SIM - so you can be reached via both numbers.
Does hotspot/tethering work with a eSIM in the USA?
Yes for some providers. Holafly supports hotspot with Unlimited tariffs, Airalo with selected packages. Tethering is particularly useful if you want to connect your laptop on road trips or in a café. Check the hotspot function in the tariff description before you buy.
What term is appropriate for the USA?
Choose the duration to suit the length of your trip: 7 days for short trips (e.g. New York weekend), 15 days for typical vacations, 30 days for longer trips or workations. Tip: It's better to book one day more than too little - most providers do not extend automatically.
Are there differences in network coverage in urban and rural areas?
Yes, considerably. In big cities (NYC, LA, Miami, Chicago) you have fast 4G/LTE or even 5G almost everywhere. In rural areas - e.g. on road trips through the Midwest, in national parks (Yellowstone, Grand Canyon) or remote highways - coverage can be patchy. Providers using T-Mobile generally offer the broadest rural coverage.
