Methodology & fine print
Scenario: one line, 30 consecutive days in a typical ZEN destination (France, Japan, Italy, Spain), roughly 5GB of total data, staying reachable every day. Carrier figures are based on publicly advertised rates as of 01/01/2026, drawn from each carrier's own pricing pages. Carrier rates are subject to change without notice, and this page should not be considered fully accurate or authoritative — always confirm current pricing with the carrier before you travel. All carrier totals are per line and exclude taxes, fees, and the underlying US plan you must already have. ZEN's price shown is the Nirvana 5GB / 30-day plan in typical destinations; exact pricing per country appears at checkout. AT&T's range reflects its cap of ten daily fees per bill cycle. T-Mobile's total reflects three back-to-back 10 Day Passes ($50 / 15GB each — the pass T-Mobile labels “Most popular”); T-Mobile also sells a $75 30-Day Pass, and its $85+/mo premium plans include 5GB of high-speed international data at no extra charge.
