ZenSim does not provide an unlimited data eSIM for GuineaโBissau. Instead, the available options are fixedโdata plans that allow a set amount of highโspeed data for a specific validity period. For example, the 20GB 10โday or 20GB 30โday plans give a larger data allowance at a reasonable price.
Choosing a fixedโdata plan can be more cost effective for most travelers, especially if you are not a very heavy user. If you anticipate needing more data than the largest offer (20GB), you would need to purchase an additional plan or use a different provider that offers unlimited service.
