Americas Roaming Costs vs eSIM Prices (2026)

The average eSIM price across 52 countries in Americas is $4.37/GB. Prices vary by country and provider. Per-GB plans start from $1.50/GB in budget destinations, while premium markets can reach $8-10/GB. Unlimited daily plans from Holafly start at $2.99/day. Regional bundles covering multiple Americas countries on a single eSIM offer the best per-GB value for multi-country trips.

Airalo covers the most countries in Americas with 200+ destinations globally. Holafly covers 178 countries with unlimited daily plans. Saily covers 150+ countries with built-in VPN protection. The best provider depends on your priorities: Airalo for breadth, Holafly for unlimited data, Saily for privacy, and Nomad for budget destinations. Check individual country pages for carrier-level coverage details.

Yes. AT&T International Day Pass charges $10/day and Verizon TravelPass charges $10/day for roaming in Americas. A 7-day trip costs $70-105 in roaming versus $8-25 for a travel eSIM covering the same period. That is a difference of 80-90%. T-Mobile's included international data throttles speeds to 256 Kbps, while eSIMs deliver full 4G/5G speeds.

Yes, with limits. T-Mobile Go5G and Magenta plans include Mexico and Canada with high-speed data, but daily caps apply (varies by plan). Once you exceed the daily cap, speeds throttle. South America, Central America, and Caribbean destinations get the standard 256 Kbps free tier, not full speed. Check your specific T-Mobile plan for exact Mexico/Canada data limits.

Major Caribbean destinations have eSIM coverage from at least one provider: Jamaica, Dominican Republic, Puerto Rico, Bahamas, Barbados, Trinidad and Tobago, and Aruba. Smaller islands like St. Kitts, Dominica, and Grenada have limited or no eSIM plan availability. Check provider coverage maps for your specific island before purchasing. Caribbean per-GB pricing is the highest in the Americas at $6-12/GB.

Yes, for port days. Cruise ship WiFi costs $15-25/day at slow speeds. An eSIM activates when you reach port and connects to local carriers at $2-6/GB. On sea days, neither eSIM nor carrier roaming works. Buy a travel eSIM before boarding and activate it at each port. Turn off mobile data while at sea to avoid ship-based satellite charges.

Brazil, Colombia, Chile, and Argentina have the strongest eSIM infrastructure in South America with plans from Airalo, Holafly, and Nomad. These countries have reliable 4G LTE from Claro, Movistar, and TIM. Peru and Ecuador have growing coverage. Bolivia, Paraguay, and Guyana have limited eSIM plan availability.

AT&T charges $10/day in Mexico. A 7-day Mexico trip costs $70. A 7GB Airalo Mexico plan on Telcel's 4G/5G network costs $10-15. Difference: $69-74 saved on a standard week. T-Mobile includes Mexico in some postpaid plans with full-speed data, but daily caps apply. For T-Mobile customers whose plan includes Mexico, the incremental cost of adding an eSIM is not justified. All other US carriers save 80%+ by switching to an eSIM in Mexico.

Holafly's unlimited Americas plan at $2.99/day is the strongest option for cruise itineraries hitting multiple Caribbean islands. You pay only for port days when your phone connects to shore-based towers. A 7-port cruise with 7 sea days costs $21 total in Holafly versus $84 in AT&T roaming for the same 7 port days. At sea, neither option charges you. Buy and install Holafly before boarding — ship WiFi is too slow for plan purchases.

Yes. Claro, TIM, and Vivo provide 4G in all major Brazilian cities including Sao Paulo, Rio de Janeiro, Brasilia, and Salvador. 5G is expanding in Sao Paulo and Rio through Claro and TIM. Airalo Brazil plans on Claro's network start at $2-3/GB. A 10GB plan covers most one-week trips. AT&T charges $10/day in Brazil — $84 for a 7-day trip versus $20-30 for a 10GB eSIM. Average savings across the Americas versus AT&T: approximately 83%.
