Why is El Salvador's 3GB eSIM plan cheaper per gigabyte than the 5GB plan?
This dataset prices El Salvador's 3GB tier at $11.97, working out to $3.99/GB, below the 5GB tier's $22.99 price, which works out to $4.60/GB. The 1GB tier costs the most per gigabyte at $4.99. Per-gigabyte cost does not fall in a straight line here as plan size increases.

Every eSIM in this five-provider comparison routes through Claro, per this dataset. Enrichment data separately lists Tigo SV and Movistar SV alongside Claro SV as El Salvador's three primary carriers, a wider local field than the single network these five eSIM providers actually connect through.

Yes. Enrichment data lists El Salvador's VPN status as unrestricted, so a VPN app works alongside any of the five eSIM providers compared here. IMEI registration is also not required, removing an added verification step some destinations impose before an eSIM activates.
Does El Salvador use the US dollar for eSIM pricing?

Yes. El Salvador's official currency is the US dollar, the same setup as several dollar-denominated destinations in this comparison, so every price listed across these five providers converts directly with no exchange-rate adjustment. A separate quirk confirms Bitcoin has also held legal tender status since 2021.
Why does El Salvador only have three eSIM plan sizes?
Why does El Salvador only have three eSIM plan sizes?
This dataset tracks just three fixed-data tiers for El Salvador, stopping at 5GB, with no 10GB or 20GB option and no unlimited tier at all. It is one of the shortest plan catalogs in this comparison, narrower than neighboring Ecuador's six-tier lineup covered elsewhere in this catalog.
