SeferESIM does not provide an unlimited‑data eSIM option for Guyana. All of its plans for the country have a set data cap and a defined validity period. Examples of the fixed data plans available include the 20 GB plan that is usable for 30 days and the 10 GB plan that is usable for 30 days. In addition, SeferESIM offers a 10 GB/day plan with a 1‑day validity or 7‑ and 14‑day extensions; these come with a reduced speed of 384 kbps.
Choosing a fixed data plan can be more cost effective for most travelers, especially those who are not extremely heavy data users. Unlimited plans are not listed, so if a traveler requires more data than the caps above, they would need to either purchase a higher‑capacity fixed plan or consider a different provider that offers unlimited data for Guyana.
