yaySIM eSIM Data Plans for Eswatini (Swaziland)

yaySIM does not provide an unlimited data eSIM plan for Eswatini (Swaziland).
Travelers can choose from fixed data plans that offer sizable data allowances, such as the 20GB bundle that lasts 90 days (GL‑120_20_90) or the 20GB bundle that lasts 30 days (GL‑120_20_30). These plans are limited in the amount of data and the validity period, so they may be more cost‑effective for most users unless high‑volume data use is required.

yaySIM does not provide an eSIM that includes a phone number or SMS capability for Eswatini (Swaziland). Only data‑only plans are available from this provider. Travelers who need voice or messaging can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, those apps may be restricted or blocked in some destinations, so users should verify that the services they rely on are accessible in Eswatini (Swaziland) before purchasing a plan.

The catalogue lists 11 plans that cover only Eswatini, and an additional 18 plans that include Eswatini as part of a broader multi‑country package. Prices for these packages span roughly $16 to $205, with data allowances ranging from 500 MB up to 20 GB and validity periods from one day to a full year. The single‑country offerings are standard fixed‑data bundles, while the multi‑country options often provide a daily data cap that can be shared across several destinations.
