Looking for the cheapest eSIM for the USA? The short answer: compare by price-per-GB, not sticker price — and the best value usually comes from a slightly larger plan, not the cheapest 1GB one.
Price snapshot: eSIM prices change frequently — this is a June 2026 snapshot. Confirm the current price on the provider’s site before buying. See the live USA eSIM comparison.
The answer first
In our June 2026 snapshot, the lowest price-per-GB for the United States comes from Saily and Nomad on their larger plans:
| Provider | Plan | Price | $ / GB |
|---|---|---|---|
| Saily | 10 GB / 30d | $18.99 | ~$1.90 |
| Nomad | 10 GB / 30d | $23.00 | ~$2.30 |
| Airalo | 10 GB / 30d | $26.00 | ~$2.60 |
| Saily | 5 GB / 30d | $14.99 | ~$3.00 |
| Nomad | 1 GB / 7d | $3.50 | ~$3.50 |
For the lowest upfront cost on a quick trip, a 1GB plan from Nomad ($3.50) or Saily ($3.99) is the cheapest way to get online. See the full table on the USA eSIM page.
How much data do you actually need?
- Light (maps, chat, email): 1–3 GB for a short trip.
- Normal (browsing + some video): 5 GB for one to two weeks.
- Heavy (streaming, hotspot): 10–20 GB, or an unlimited Holafly plan priced per day.
Because larger plans cost less per GB, buying 5–10GB is usually better value than topping up several 1GB plans. Test any two plans with the price-per-GB calculator.
What about unlimited?
Holafly sells unlimited US data priced per day (around $6–7/day). It only beats a fixed plan if you genuinely use a lot of data; for most travellers a 5–10GB plan from Saily, Nomad or Airalo is cheaper.
