EZsim does not provide an unlimited data eSIM plan for Zambia. All plans listed for Zimbabwe include a capped data allowance, such as 20 GB, 10 GB, 5 GB, or 3 GB over a 30‑day period. EZsim offers fixed data plans that cover Zambia and, in some cases, neighboring countries. For example, the 20 GB/30 days plan is priced at $90.50 USD, and the 10 GB/30 days plan costs $40.00 USD. These plans allow tethering and may suit most travelers who need a generous amount of data. Choosing a fixed data plan can be more cost effective unless a user requires extremely high data consumption beyond the largest available offering.
