No travel eSIM sold as unlimited is truly unlimited. Traviva’s pick for heavy users is Saily, which publishes the most generous daily allowance: 5GB a day at full speed, then 1 Mbps. Airalo and Maya Mobile allow 3GB a day and Nomad 2GB a day; Ubigi’s 30-day unlimited plans give 60GB at full speed in total, then 2 Mbps; and Holafly publishes no figure at all.
Updated · Each figure comes from the provider’s own published terms; Ubigi’s unlimited allowance was re-checked on 8 October 2026.
| Provider | Full speed until | Then throttled to | Hotspot | Phone number |
|---|---|---|---|---|
| Saily | 5GB/day | 1 Mbps | Unlimited | Optional paid add-on |
| Airalo | 3GB/day | 1 Mbps | Unlimited | On some Data, Voice & Text packages and Discover+ |
| Nomad | 2GB/day | 512 kbps | Supported | Thailand 50GB plan only, per review; otherwise unclear |
| Ubigi | No daily cap — 60GB per 30-day plan (5GB in China) | 2 Mbps | Unlimited | Never — data only, no SMS |
| Holafly | ~2–3GB/day per third-party analysis; Holafly publishes no figure | 256–1024 kbps | 1GB/day | Never |
| Maya Mobile | 3GB/day | 10 Mbps, then 1 Mbps | Allowed, with guidance | No — data only, on every plan |
| Simify | No firm figure published — a help article says around 1–1.5GB | around 3 Mbps | Allowed | No — data only |
What each provider actually does
| Provider | The fair-use policy in plain English |
|---|---|
| Saily | Full speed until you use 5GB in a 24-hour period, then 1 Mbps for the rest of that day. The allowance resets daily. |
| Airalo | Full speed until you use 3GB in a 24-hour period, then 1 Mbps for the rest of that day. The allowance resets daily. |
| Nomad | Full speed until you use 2GB in a 24-hour period, then 512 kbps for the rest of that day. The allowance resets daily. |
| Ubigi | No daily cap. Instead, each unlimited plan has a fixed full-speed allowance and then an unlimited 2 Mbps tail: 60GB on 30-day plans, and only 5GB in China. Shorter plans carry smaller allowances. Ubigi sells unlimited in most of our destinations, but not in Fiji. |
| Holafly | Holafly publishes no figure at all, though third-party analysis puts it near 2–3GB a day. Where it does slow you down, it says the speed is 256–1024 kbps. Not knowing the threshold is itself the problem. |
| Maya Mobile | Full speed until you use 3GB in a 24-hour period, then 10 Mbps, then 1 Mbps. Maya says any throttle applied is removed within 24 hours — the only restoration time anyone on this page publishes. |
| Simify | Simify publishes no firm figure at all — only an approximate 1–1.5GB, and only in a troubleshooting article rather than on any plan page. Where it does slow you down, it says the speed is around 3 Mbps. Not knowing the threshold is itself the problem. |
What the throttled speeds mean
The cap matters less than what happens after it. Once you are throttled:
- 1 Mbps (Saily, Airalo) still carries maps, messaging, email, and standard-definition video that buffers. It is annoying, not crippling.
- 512 kbps (Nomad) is enough for maps and text. Video is not realistic, and photo uploads crawl.
- 256 kbps (the bottom of Holafly’s reported range) is close to unusable for anything but plain messaging.
How much data do you actually use?
Most travellers who are not streaming video use between 500MB and 1.5GB a day — maps, messaging, social feeds, a few uploads. On that pattern, none of these caps will ever bite, and buying unlimited is usually a waste. A 10GB fixed plan for a two-week trip costs a third of the unlimited price on almost every provider here.
Unlimited earns its price in two situations: you are tethering a laptop and working, or you genuinely cannot predict your usage. In the first case, check the hotspot rules before anything else — because that is where the real restriction lives.
How we got these numbers
Airalo and Saily publish their fair-use figures openly and we quote them directly. Nomad’s appears in its terms. Holafly publishes no figure, so the range shown comes from third-party analysis of its terms and is labelled as such throughout — we would rather show you an honest uncertainty than a confident guess. Ubigi states the full-speed allowance on each plan page; we re-checked it on 8 October 2026.
Airalo publishes its fair-use figure openly: 3GB a day at full speed on unlimited plans, then 1 Mbps for the rest of the day.

Fair-use questions travellers ask
Are unlimited travel eSIMs really unlimited?
No. Every travel eSIM sold as unlimited slows you down after a set amount of full-speed data, either per day or per plan. Most providers make you go looking for the number.
Which travel eSIM has the biggest daily allowance?
Saily: 5GB a day at full speed, then 1 Mbps for the rest of the day. Airalo and Maya Mobile allow 3GB a day and Nomad 2GB a day.
What happens when I hit the fair-use cap?
Your speed drops for the rest of the day: to 1 Mbps with Saily and Airalo, which still handles maps, messaging and email; to 512 kbps with Nomad, which is enough for maps and text; and to as low as 256 kbps with Holafly, which is close to unusable for anything but messaging.
Does Ubigi have a daily cap on unlimited plans?
No daily cap. Its 30-day unlimited plans run at full speed for the first 60GB, then 2 Mbps for the rest of the plan; in China the full-speed allowance is only 5GB.
How much data do travellers use per day?
Most travellers who are not streaming video use between 500MB and 1.5GB a day on maps, messaging, social feeds and a few uploads. On that pattern none of these caps will bite, and a fixed-data plan is usually cheaper.
When is an unlimited eSIM worth it?
In two situations: you are tethering a laptop and working, or you genuinely cannot predict your usage. If you are tethering, check the hotspot rules first, because that is where the real restriction lives.
