Provider Deep Dive

Airalo for USA: T-Mobile network review.

Airalo connects to T-Mobile in the United States. T-Mobile covers 99% of the US population with 4G LTE and offers 5G in over 300 cities. Download speeds in urban areas range from 25-100 Mbps on LTE and 100-300 Mbps on 5G.

Airalo USA plans start at $4.50 for 1 GB (7 days) and scale to $40.00 for 10 GB (30 days). The per-GB cost decreases on larger plans: $4.50/GB at 1 GB, $4.33/GB at 3 GB, and $4.00/GB at 10 GB. Hotspot tethering is supported on all US plans.

Coverage extends to all 50 states including Hawaii and Alaska. Major cities — New York, Los Angeles, Chicago, San Francisco, Miami, Las Vegas — have consistent LTE and 5G. Rural areas and national parks may have gaps, but T-Mobile has improved rural coverage significantly after its Sprint merger.

Provider Deep Dive

Holafly for USA: AT&T unlimited review.

Holafly uses AT&T for its unlimited USA plans. AT&T covers 97% of the US population with LTE. The main advantage is unlimited data priced by duration: 5 days for $19.90, 7 days for $27.90, 15 days for $47.90, and 30 days for $73.90.

The fair-use threshold is approximately 5 GB per day. After that, speeds drop to around 1 Mbps, which handles maps and messaging but not video streaming. For most travelers, 5 GB per day is more than enough.

Holafly does not support hotspot tethering on US plans. Data is for the primary device only. If you need to share data with a laptop or tablet, choose Airalo or Nomad instead. This is the main trade-off for unlimited data.

Provider Deep Dive

Saily for USA: the VPN advantage.

Saily connects to T-Mobile in the US and includes NordVPN at no extra cost. A 1 GB plan costs $3.99 and a 5 GB plan costs $12.99. The 30-day validity window is useful for trips that span multiple weekends.

The VPN is relevant for travelers who access banking, work email, or personal accounts on public WiFi in cafes, airports, and hotels. While cellular connections are already encrypted, the VPN adds a second layer that prevents local network snooping.

Saily supports hotspot tethering, making it a practical alternative to Holafly for travelers who need both privacy and laptop connectivity.

Provider Deep Dive

Nomad for USA: the cheapest option.

Nomad offers the lowest entry price for USA eSIM plans. A 1 GB plan costs $5.00. A 3 GB plan costs $10.00 ($3.33/GB). A 5 GB plan costs $13.00 ($2.60/GB). For a 3-day weekend trip, the 1 GB plan is hard to beat on price.

Nomad uses T-Mobile in the US. Hotspot is supported. The main trade-off is customer support — email only, with a 12-24 hour response window. For budget travelers who are comfortable troubleshooting on their own, Nomad delivers the most data per dollar.

Network Analysis

T-Mobile vs AT&T for international travelers.

T-Mobile and AT&T are the two US networks available through travel eSIM providers. Verizon does not participate in the travel eSIM market due to CDMA legacy restrictions and network access policies.

T-Mobile (Airalo, Saily, Nomad)

  • 99% population coverage with 4G LTE
  • 5G available in 300+ cities
  • Strongest rural coverage after Sprint merger
  • Typical speeds: 25-100 Mbps LTE, 100-300 Mbps 5G
  • Better indoor penetration with extended range 600 MHz

AT&T (Holafly)

  • 97% population coverage with 4G LTE
  • 5G access not included on travel eSIM plans
  • Strong urban coverage, weaker in rural Midwest
  • Typical speeds: 20-75 Mbps LTE
  • FirstNet infrastructure provides resilience in emergencies

For most travelers visiting major US cities, both networks perform equally well. T-Mobile has the edge for road trips, national parks, and rural areas. AT&T via Holafly only makes sense when you need unlimited data without tracking.

Hotspot

Hotspot and tethering policies for USA plans.

Hotspot tethering lets you share your phone's eSIM data connection with a laptop, tablet, or travel companion's device. This matters for travelers who work from cafes or need a laptop connection at hotels with unreliable WiFi.

Airalo, Saily, and Nomad all allow hotspot on US plans. Your data allowance is shared between your phone and the tethered device. There is no separate hotspot cap on these plans.

Holafly does not support hotspot on unlimited US plans. The unlimited data is restricted to the primary device. Attempting to enable personal hotspot with a Holafly eSIM active will either fail or route traffic through your home SIM instead.

FAQ

USA eSIM questions.

Which network do eSIM providers use in the USA?

Yes. A T-Mobile prepaid SIM at a US airport costs $30-$50 for 10 GB. An eSIM from Nomad or Airalo delivers comparable data for $13-$25. The eSIM also installs before you land, so you skip the airport kiosk entirely.
