AeriSIM does not offer an unlimited data eSIM for Canada. Instead, the provider offers fixed data plans that give up to 50GB of high‑speed data for a set number of days. For example, there is a 50GB plan valid for 3 days, another valid for 5 days, and plans up to 15 days. These fixed plans can provide a substantial amount of data for most travelers, and for users who need more data over a longer period they may be more cost‑effective than a pay‑as‑you‑go option.
