The following data amounts are editorial planning assumptions, not measured app averages or a usage guarantee. Calculate your own daily use × trip days plus a reserve you choose. Video, backups and hotspot use can change requirements substantially.
eSIM for the USA
Roaming charges in the USA are particularly high. With a mySIM24 eSIM you get online nationwide at fair prices – no local SIM and no contract.
Network coverage
Available networks and speeds depend on the specific plan, device and location. Continuous 4G or 5G service is not guaranteed. Save essential maps and bookings offline before remote stretches.
Which plan?
- City break: 5–10 GB
- Road trip (2–3 weeks): 20 GB or unlimited daily packages

Installation
Check the activation policy in the plan details before buying. Depending on the plan, validity starts at purchase, on installation or on the first connection to a supported network. Install the profile over reliable Wi-Fi at the time recommended for your plan.
What is different in the USA?
Distances are vast and network quality varies by state and carrier. Cities generally have strong 4G/5G, while national parks and remote highways can have dead zones. Download offline maps for road trips and check the local partner listed by the plan.
Data by itinerary
For a one-week city visit, 5–10 GB is often enough. A two- or three-week road trip with navigation, restaurant searches and social media is more comfortable with 20 GB. Laptop work requires a plan that explicitly supports hotspot use.
iPhones and US devices
Many iPhones sold in the US from the iPhone 14 generation are eSIM-only. European variants can still combine a physical SIM and eSIM. Set up before departure and follow our iPhone eSIM guide.
After landing
Select the USA eSIM for mobile data, toggle airplane mode once and leave network selection on automatic. A trip into Canada or Mexico requires those countries to be explicitly included.

Plan checklist for the USA
Do not compare price alone. The package should cover the whole trip and match the way you use data:
- Validity begins at the right time
- Allowance includes roughly 20 percent headroom
- 4G/5G and available partner networks are described clearly
- Hotspot is permitted when sharing with a laptop or companion
- A top-up or replacement package is available if use increases
For multi-state road trips, route coverage and hotspot support matter more than peak speed in a city centre.
Small or large allowance?
For maps, messaging and occasional searches, 5–10 GB often covers one week. Regular video, cloud photos, video calls or tethering point towards 20 GB or an unlimited plan. Always read “unlimited” together with daily high-speed limits and fair use. The travel data guide helps calculate an allowance.
the USA eSIM FAQ
Does the travel eSIM include a phone number? Many offers are data-only. Keep the familiar number active on the home SIM while messaging apps use the eSIM connection.
Check the activation policy in the plan details before buying. Depending on the plan, validity starts at purchase, on installation or on the first connection to a supported network. Install the profile over reliable Wi-Fi at the time recommended for your plan.
What if it shows no service? Check the selected data line, roaming instructions, automatic network selection and APN. Do not delete the profile too quickly because QR codes are often single-use.
