merdata does not provide an unlimited data eSIM for the Philippines. The plans listed by the provider only offer fixed data allowances, with the largest bundles giving 50 GB of high‑speed data for either 30 days or 180 days, and a smaller 20 GB bundle for 30 days. These options are fixed data plans that must be used within the stated validity period, rather than Pay‑as‑you‑go credits.
Choosing a fixed data plan can be more cost‑effective for most travelers, especially if data usage is moderate to high but not extreme. For example, the 50 GB 30‑day plan costs $64.19 USD and the 50 GB 180‑day plan costs $74.91 USD, while the 20 GB 30‑day plan is available for $32.04 USD. If a traveler needs unlimited data, they would need to look at other providers.
