Family trip
Two travelers on Verizon in United States for 10 days: 2 lines x $10/day x 10 = $200. Two 20GB eSIMs: $68.92. Savings: $131.08 for the couple. If only one person needs heavy data, one eSIM with tethering costs $34.46 total and covers both devices through the phone's hotspot feature.
Business trip
Day 1 in United States: AT&T charges $10 the moment you turn on your phone at the airport. Day 2: another $10 triggered by a background sync at 6 AM. Day 3: $10 more, totaling $30 for a 3-day trip. A 20GB eSIM costs $34.46 for all three days combined. For a team of three: AT&T total $150 vs eSIM total $103.38. Savings: $46.62.
Long-stay and digital nomads
A weekend (3-day) trip to United States: AT&T roaming costs $30. An eSIM costs roughly $10.01. Savings: $19.99. A 14-day trip: AT&T costs $140. eSIM costs $22.26. Savings: $117.74. Carrier roaming adds $10 for every extra day. An eSIM plan covers a fixed period regardless of daily charges. The break-even point is day one in United States.
Frequent traveler annual savings
Annual eSIM savings for 4 trips to United States: $262.16. That covers 1 round-trip Uber rides, 5 museum admissions, or 17 meals in United States. The data connection is identical on T-Mobile; the savings go toward experiences.
Extended stay economics
Two weeks in United States on AT&T International Day Pass: $10/day x 14 = $140. Verizon TravelPass: $140. T-Mobile high-speed add-on: $210. A 20GB eSIM on T-Mobile covers the same 14 days for $22.26. That is $117.74 less than AT&T (84% savings). The per-day cost of the eSIM works out to $1.59/day vs AT&T's fixed $10/day. United States also has unlimited daily eSIM plans at $3.49/day, which totals $104.70 for 30 days of unrestricted data.
Frequent flyer savings
A traveler who visits United States twice a year on AT&T International Day Pass: 2 trips x 10 days x $10/day = $200/year in roaming charges. Two 20GB eSIMs on T-Mobile: $68.92/year. Annual savings: $131.08. Over five years, that compounds to $655.40 in avoided roaming fees.
Data usage savings
Light data users — email, messaging, occasional maps — use 300-500 MB/day in United States. Over 10 days: 4.0 GB total. AT&T still charges the full $10/day regardless: $100. An eSIM at $1.06/GB for 4.0 GB costs $4.24. Light users overpay the most on carrier day passes — the fixed fee exceeds their actual consumption value.
Couples trip savings

Total cost: $34.46 for both devices over 10 days. Compare: AT&T charges $200 for two lines ($10/day each). Savings: $165.54. Trade-off: the second phone needs to stay within WiFi hotspot range of the first.
UK carrier comparison
UK carriers lost EU free-roaming after Brexit. Vodafone and EE now charge GBP6/day for rest-of-world destinations including United States. Some plans still include EU roaming, but United States may or may not fall under that zone. A 20GB eSIM at $34.46 applies the same rate regardless of EU classification. UK travelers save $25.54 vs Vodafone and $25.54 vs EE for 10 days.
