Yes, GlobaleSIM sells eSIM plans that include a phone number and SMS service for Eswatini (Swaziland). The plans range from 1GB to 20GB of data and from 7 days to 30 days of validity, with prices starting at $6.00 USD for the smallest 1GB, 7‑day plan and going up to $59.00 USD for the largest 20GB, 30‑day plan. Each plan provides a phone number with the international dialing code +1. The number is a US‑based line, not a local Eswatini number.
Calls can be made to and received from the +1 number, and text messages can be received, but outgoing SMS is not supported. Travelers who need specific call or messaging features should confirm the details directly with GlobaleSIM before purchase.
