What does "unlimited" really mean?

Nearly every "unlimited" eSIM on the market includes a Fair Usage Policy (FUP): you’ll never run out of data, but high-speed data is limited to a daily allowance. What differs is the size of that allowance—and the reduced speed afterward—details many providers omit. Zyesims clearly lists both figures for each country in the table above.

Unlimited or fixed-data plan?

  • Choose Unlimited if you don’t want to monitor your data, use maps all day, make video calls, or post photos frequently.
  • Choose a fixed-data plan if your daily usage stays under 1 GB—usually cheaper; check individual country pages for pricing.
  • Choose Plus or Premium if you need to share a hotspot with travel companions or work remotely.

1GB high-speed data ≈ 3.3 hours of 360p video or 0.9 hours of 720p HD video (estimated using YouTube’s recommended bitrates).

Frequently asked questions about unlimited eSIMs

Are unlimited eSIMs truly unlimited?

Unlimited data: your connection won’t drop mid-trip. However, high-speed data is limited daily—1 GB for Unlimited, 3 GB for Unlimited Plus; once exhausted, speeds will be reduced until your daily allowance resets. Unlimited Premium (available in select countries) has no high-speed data limit. Post-limit speeds for Unlimited plans range from 256 Kbps to 1.25 Mbps depending on the country—see the comparison table above.

What can I still do after hitting the high-speed limit?

At ~256–384 Kbps: messaging, email, and Google Maps work fine; app-based voice calls may be unstable. At 1 Mbps or higher: social media browsing, 360p video streaming, and low-quality video calls are smooth. HD video and laptop hotspotting require higher speeds—choose Plus or Premium if you rely on these heavily.

Which countries offer Unlimited plans?

Currently available in 19 destinations: Bahamas, China, Costa Rica, France, Gambia, Germany, Haiti, Italy, Japan, Malaysia, Mauritius, Mozambique, Singapore, South Korea, Spain, Taiwan, Thailand, United States, Vietnam. Each country has its own page listing the local carrier, post-limit speed, and per-day pricing.

Unlimited or Fixed-Data Plan: Which Should You Choose?

Choose Unlimited if you don’t want to monitor your data usage—or if you have heavy usage days (e.g., all-day navigation, video calls, photo uploads). Choose a fixed-data plan if your daily usage is consistently under 1 GB—these are usually more affordable. See: 1GB high-speed data ≈ 3.3 hours of 360p video or 0.9 hours of 720p HD video (estimated using YouTube’s recommended bitrates).

Can I share a hotspot with other devices?

Yes. Note that hotspot usage counts toward your plan’s high-speed data allowance — a single laptop can quickly consume 1GB, and carriers may throttle speeds when hotspotting. For group sharing, we recommend Unlimited Plus or Premium.

When does the plan’s validity period begin?

The number of days starts when your eSIM first connects to mobile data at your destination — not from the purchase date. We recommend installing your eSIM before departure and only enabling it upon landing.

Why are long-term plans cheaper?

Zyesims’ unlimited eSIM plans use tiered pricing based on total duration rather than a flat daily rate — the longer you travel, the lower your average daily cost. Your savings are shown clearly for each tier as you select.
