ZenSim does not provide a true unlimited data eSIM for Guinea. The only plan that carries the word “Unlimited” in its title, “Guinea Unlimited STANDARD - 5 Days, ” actually offers a 3 GB/day allocation for 5 days, after which the connection speed drops to 1000 kbps.
Travelers looking for more data can choose from ZenSim’s fixed data plans, such as the 20 GB plans valid for 15 or 30 days, the 10 GB options for 15 or 30 days, or the 5 GB bundle with a 15‑day validity. These plans give a set high‑speed data allowance within the specified period and are generally more cost‑effective unless a user requires a truly unlimited data experience.
