A travel eSIM on Claro SV starts at $4.99 for 1GB — the same 4G LTE network at a fraction of the daily roaming cost.
- Is T-Mobile's free international data fast enough in El Salvador?
- No. 256 Kbps sounds like it covers light use, but even a single email with an attachment or a 30-second map route takes over a minute to load at that speed.

That is how per-day billing works — any cellular connection, even a background sync at midnight, triggers the full daily charge. Without a day pass, AT&T charges $2.05/MB. A 15-second Instagram scroll could cost $30. An eSIM at 1GB for $4.99 is a fixed cost: no per-day triggers, no per-MB metering, no bill surprises.

AT&T International Day Pass at $10/day covers all social media but applies the full daily fee regardless of how little you use.
