If you’re a remote worker, a content creator, or just someone who panics at the sight of a “Low Data” warning, unlimited eSIM plans are worth looking at. But “unlimited” in eSIM marketing often means “unlimited with asterisks.” Let me decode the reality.
### The Unlimited eSIM Players for Southeast Asia
| Provider | Plan | Price (15 days) | Price (30 days) | True Unlimited? |
|—|—|—|—|—|
| Holafly | SEA Unlimited | ~$27 | ~$45 | Throttled after heavy use |
| Nomad | SEA Unlimited | ~$25 | ~$39 | Throttled after very heavy use |
| Jetpac | SEA Unlimited | ~$20 | ~$35 | Throttled at 1GB/day |
| Airalo | N/A | N/A | N/A | No unlimited plans |

### What “Unlimited” Actually Means
No eSIM provider offers truly unlimited data at full 4G speeds indefinitely. The reality:
– **Holafly:** Full 4G speeds until network congestion or heavy sustained use triggers throttling. Throttled speeds: approximately 1-3 Mbps.
– **Nomad:** Slightly more generous before throttling. Throttled to 1-5 Mbps.
– **Jetpac:** 1GB/day at full speed, then throttled. Best if your use is fairly consistent day-to-day.
### Real-World Speed Tests (Unlimited Plans)
| Location | Holafly Unlimited | Nomad Unlimited |
|—|—|—|
| Bangkok (morning) | 32 Mbps ↓ | 35 Mbps ↓ |
| Bangkok (evening peak) | 15 Mbps ↓ | 20 Mbps ↓ |
| Chiang Mai | 28 Mbps ↓ | 30 Mbps ↓ |
| Bali, Canggu | 22 Mbps ↓ | 24 Mbps ↓ |
| HCMC, Vietnam | 38 Mbps ↓ | 40 Mbps ↓ |
| After heavy day of use | 3-8 Mbps ↓ | 8-15 Mbps ↓ |
### When Unlimited Is Worth It
**Worth paying for unlimited if:**
– You do Zoom/video calls 2+ hours daily
– You upload video content regularly
– You tether a laptop for work
– You have extreme data anxiety
– You’re in SEA for 3+ weeks
**Not worth it if:**
– You mainly use Maps, WhatsApp, Instagram
– Your trip is under 10 days
– You work from co-working spaces with WiFi
– You use under 10GB/month normally
### My Recommendation
For most remote workers doing a stint in Southeast Asia: **Nomad unlimited is the better value** — slightly cheaper, slightly better at sustaining speeds under heavy use.
For those who want the security of excellent live support alongside unlimited data: **Holafly** is worth the small premium.
For travellers who just want peace of mind but don’t actually use much data: **don’t bother with unlimited.** Airalo’s 10GB plan at $17 is probably all you need.
