Best eSIM for USA in 2026

TL;DR

For most visitors to the USA, Airalo is the strongest pick — brand recognition, T-Mobile/AT&T backbone, and predictable pricing make it the safe default. Saily (NordVPN’s eSIM) is a strong runner-up if you value reliability and integrated VPN. Simsimsim ranks #4 — cheaper on both small GB plans and Daily Unlimited (now $61.90/30 d vs Holafly’s ~$67), crypto-friendly, but we’re new. Prices below are approximate and move with promotions.

How we ranked

Five criteria: US carrier backbone (T-Mobile vs AT&T vs Verizon), realistic price for 1–10 GB plans, plan structure, payment methods, and reputation. The US is unusual because direct carrier prepaid SIMs (Mint Mobile, T-Mobile Connect) are often cheaper than international eSIM resellers for long stays — so we included one carrier option for honesty.

Disclosure: Simsimsim is one of the providers on this list. We’ve ranked ourselves #4 because three competitors have longer track records and broader coverage. We’re cheaper on small buckets; that’s not enough to claim #1.

The shortlist

#1. Airalo — the safe default

Airalo’s USA plan (“Change”) runs on a T-Mobile/AT&T blend and covers the entire country including most national parks. For visitors, it’s the most-recommended option in travel forums for good reason.

• Coverage: 200+ countries; US plan on T-Mobile/AT&T
• Plans: 1/3/5/10/20 GB, 7–30 days
• Cheapest: ~$4.50 for 1 GB / 7 days
• App: Yes (iOS/Android)
• Trustpilot: ~4.6/5 (very large sample)

Where it wins: Brand trust, app-based install, robust coverage. Where it loses: Pricier than smaller players on entry plans, data-only. Verdict: Default choice for non-technical travellers.

#2. Saily — NordVPN reliability

Saily is run by Nord Security (NordVPN). The infrastructure pedigree shows: connection drops are rare and they bundle ad/tracker blocking.

• Coverage: 150+ countries
• Plans: 1/3/5/10/20 GB, 7–30 days
• Cheapest: ~$3.99 for 1 GB / 7 days
• App: Yes (iOS/Android)
• Trustpilot: ~4.5/5

Where it wins: Built-in ad/tracker blocking, NordVPN brand backing, slightly cheaper than Airalo. Where it loses: Smaller country list, app-heavy. Verdict: Strong pick if you already use NordVPN or care about privacy.

#3. Holafly — original Daily Unlimited brand

Holafly’s daily unlimited plan in the USA runs on T-Mobile. Fair-use throttle kicks in around 5 GB/day in our testing. They built their name on this product and have the longest track record.

• Coverage: 200+ countries
• Plans: Daily unlimited, 5/10/15/20/30/60/90 days
• Cheapest: ~$19 for 5 days unlimited; ~$67 for 30 days
• App: Optional
• Trustpilot: ~4.7/5

Where it wins: Long Trustpilot track record, polished checkout, generous daily cap. Where it loses: Expensive for light users, FUP buried in fine print, we now undercut their 30-day Unlimited by ~$5 in the USA. Verdict: Worth the premium only if brand reputation matters more than $5–$10.

#4. Simsimsim — cheaper data, Daily Unlimited, crypto payments

We’re a new brand. For the USA specifically, we’re cheaper than Airalo on small plans, cheaper than Holafly on Daily Unlimited (1 GB/day × 30 d = $61.90 vs Holafly’s ~$67), accept crypto, and don’t require an app. We don’t have a Trustpilot history yet.

• Coverage: 186 countries including USA
• Plans: GB buckets (1/3/5/10/20 GB) + Daily Unlimited (1/2/3/10 GB per day × 7/15/30 days)
• Cheapest GB plan: ~$3.90 for 1 GB / 7 days
• Cheapest Daily Unlimited: $15.90 for 1 GB/day × 7 days
• App: No — QR by email
• FUP disclosure: Shown on every product card (post-cap speed visible upfront)
• Trustpilot: No meaningful sample yet

Where it wins: Cheapest small-bucket plan here, cheapest Daily Unlimited in this list, USDT/BTC checkout, $5 welcome credit on plans ≥$5, no app friction, FUP disclosed upfront. Where it loses: No brand history. Verdict: Honest pick for budget travellers, heavy-data travellers willing to skip the Holafly brand premium, or anyone whose card was rejected by Airalo/Saily.

#5. Mint Mobile / T-Mobile direct — carrier alternative

If you’re in the USA for 3+ weeks, prepaid carrier plans usually beat eSIM resellers. Mint Mobile offers 5/15/20/40 GB monthly plans starting around $15.

• Coverage: US only (T-Mobile network)
• Plans: Monthly, 5/15/20/40 GB
• Cheapest: ~$15/month for 5 GB
• App: Yes
• Trustpilot: ~3.2/5 (customer service complaints)

Where it wins: Best per-GB price for long stays, includes US phone number. Where it loses: US-only, activation can require a US address. Verdict: Long-stay only.
