Best eSIM U.S. 2025: Complete guide to providers

Are you about to leave for the US and don’t want to get fleeced by roaming charges? Great, you’ve come to the right place. I’ll explain everything you need to know to choose the best eSIM for the U.S. without wasting time (and money) on tourist pitfalls.

Why use an eSIM to travel to the U.S.

Let’s face it: mobile data in the United States costs an arm and a leg. With classic physical SIM cards, you risk paying crazy amounts of money or running out of connection just when you need it. The eSIM for USA solves all these problems in one fell swoop.

The benefits are clear as day:

• Guaranteed savings: goodbye to roaming charges that drain your bill
• Instant activation: download, activate and be online in 2 minutes
• Multi-operator coverage: access to AT&T, T-Mobile and Verizon networks
• Zero stress: no airport lines or desperate search for stores

How to choose the best US eSIM?

Assesses network coverage

AT&T vs T-Mobile: here’s the truth no one tells you. AT&T dominates in rural areas and along highways, T-Mobile is strong in cities. If you go on a desert road trip, go for AT&T. If you stay in New York and Los Angeles, T-Mobile is perfect.

How many GBs are really needed?

Don’t be fooled by “unlimited data” -always read the fine print. Here is my rule of thumb:

• 5GB: weekend in Miami, basic use
• 10GB: standard week with maps and social
• 20GB: business trip or heavy use
• 50GB+: digital nomad or continuous streaming

Duration of the trip

• 7-15 days: most convenient short plans
• 30 days: sweet spot for most offers
• Frequent travel: consider annual plans like KeepGo

5G support: when you really need it

5G pays off if:

• Do you often use the laptop hotspot
• Video posts on Instagram/TikTok
• Remote work with video calls
• Stream in 4K

US provider reviews

• Not the cheapest ever
• Data only, no calls

Real speed tests: in my tests in New York I recorded 45 MB/s download with T-Mobile 5G. More than enough for any use.

Holafly USA: “unlimited” data with asterisk

Pros:

• Captivating marketing on unlimited data

• Only one network available
• Fewer duration options

Strengths: Ideal for medium-duration business travel.
