eSIMCard does not provide a truly unlimited high‑speed data plan for Guinea‑Bissau. The plans that are labelled “Unlimited” actually allow only 1GB or 2GB of data per day; once that data cap is reached the speed is throttled to 500 kbps or 2000 kbps.
For travelers who need more data, eSIMCard offers fixed‑data plans. Examples include a 20 GB plan valid for 31 days (priced at $22.70 USD) that provides unthrottled 4G/5G access in Guinea‑Bissau and over 100 other countries, a 20 GB plan for 30 days costing $207.61 USD, a 10 GB plan for 30 days at $115.59 USD, a 5 GB plan for 30 days at $63.01 USD, and a 3 GB plan for 30 days at $38.21 USD. These fixed‑data options give a set amount of high‑speed data without automatic reduction until the defined data allowance is used.
