USA Networks — What Matters
US mobile coverage runs on three main networks: T-Mobile, AT&T and Verizon. Most travel eSIMs run on T-Mobile's network — which has excellent coverage in cities and along the coasts, but can be patchy in rural areas.

Best for a City Trip (NYC, LA, Chicago)
Airalo's US plans are reliable and well-priced for city visits. Their "North America" regional plan also covers Canada and Mexico if you're crossing borders.
Best for Calls + Data
If you need a working US phone number (to receive calls, use apps that need SMS verification, etc.), Yesim's virtual number add-on is the most seamless option.
Best Budget Option
Saily offers clean, simple US plans at competitive prices — good if you just need data and want to keep it simple.
Buy Before You Fly: You can install the eSIM before you board — it won't activate and start consuming data until you arrive in the US. Set everything up from home and be online the moment you land.
How Much Data Do You Need for the US?
For a 10-day city trip with normal use (maps, WhatsApp, social media, occasional streaming): 5–10GB is comfortable. If you're using Google Maps heavily or streaming video, go for 10GB or unlimited to be safe.
Get Your US eSIM Before You Land
Activate on arrival — no roaming surprises.
