## I Tested 7 eSIM Providers in Asia — Here’s What Nobody Tells You
[IMAGE:flat-design-seven-phones-signal-test-comparison-flat-illustration]
I’ve been writing about eSIMs for Southeast Asia for two years. I’ve read hundreds of other articles. And I’ve noticed a consistent pattern: most guides tell you what works, but not what the limitations are, where the marketing diverges from reality, and what the actual downsides are of each provider.
This is my attempt to fill that gap.

### What Nobody Tells You About Airalo
**The good no one disputes:** Airalo is genuinely the best-value eSIM marketplace. The pricing is honest and competitive.
**What they don’t shout about:**
– Customer support response times are genuinely slow (12-36 hours)
– Data speeds can be throttled even on fixed-data plans during network congestion
– Some country plans have very limited partner networks — the “Asia” regional plan uses different networks in different countries, and quality varies
– The referral Airmoney credits expire — don’t let them sit there unused
### What Nobody Tells You About Holafly
**The “unlimited” illusion:** Holafly’s unlimited plans are throttled after heavy sustained use. The small print acknowledges this but the marketing leads with “UNLIMITED” in large text. In Bali during a busy client month, I experienced speeds as low as 2 Mbps during evening peak hours.
**That said:** For casual travel, 2 Mbps is sufficient for messaging and maps. It’s only a problem if you’re genuinely doing heavy video work.
### What Nobody Tells You About Nomad
Nomad has a smaller user community and less social proof than Airalo, which means it’s harder to find trustworthy independent reviews. My honest assessment: Nomad performs equivalently to Airalo in most situations but with slightly better rural coverage. The lower profile isn’t a quality indicator — it’s just smaller marketing budget.
### The “5G” Marketing That Mostly Doesn’t Matter
Some providers now advertise “5G eSIM plans.” In most of Southeast Asia in 2025, this is largely irrelevant:
– Thailand has 5G only in central Bangkok and a few major cities
– Vietnam has limited 5G rollout
– Cambodia, Laos, Myanmar — no 5G
You’re probably getting 4G LTE 95% of the time regardless of what the plan says. Don’t pay extra for “5G” unless you’re specifically in a city with confirmed 5G coverage and have a 5G phone.
### The Coverage Map Deception
Every eSIM provider has a coverage map. Those maps show network coverage — not the eSIM provider’s actual coverage. When a provider says “coverage in Thailand,” they mean their partner network (e.g., AIS) covers Thailand. But your actual eSIM performance depends on:
– How the partnership agreement works
– Whether you get 4G or 3G in a given area
– Network congestion at the time you’re using it
Coverage maps should be treated as rough guides, not guarantees.
### Price Comparison Sites Are Often Outdated
Airalo, Holafly, and Nomad regularly change their pricing. Many “comparison” articles were written once and never updated. Always check the actual provider app for current prices before buying.

### The Truth About eSIM “Refunds”
Most providers will refund uninstalled plans. Once installed, refunds are rarely issued even if the plan performs poorly. Before purchasing, check the specific plan’s refund policy — it varies by plan, not just by provider.
### My Actual Take After Two Years
ESIM has been genuinely transformative for my travel. I’ll never queue at an airport SIM counter again. But the marketing is rosier than the reality:
– “Unlimited” means “limited at a throttled speed after heavy use”
– “Excellent coverage” means “4G in major cities, 3G in rural areas”
– “Instant setup” means “5 minutes if everything works perfectly”
– “Customer support” means “email, often slow”
None of this is deal-breaking — eSIM is still genuinely excellent. Just go in with accurate expectations.
