Detailed analysis of two major eSIM providers: features, pricing, technology, and user experience for international travel
Deciding between unlimited eSIM providers for international travel? Two prominent options dominate the conversation: Holafly, the established unlimited data specialist, and Truely, the revolutionary Switchless™ technology pioneer. Both providers offer unlimited data solutions, but they represent different generations of eSIM technology with dramatically different capabilities.
This comprehensive comparison examines both providers across technology, pricing, coverage, and user experience to help you choose the optimal eSIM solution for your specific travel needs.
Data in this article is valid until August 2025.
Holafly and Truely both offer unlimited data, but their approaches differ fundamentally. Holafly uses traditional technology with unlimited plans that include speed throttling, while Truely pioneers revolutionary automated systems with true unlimited connectivity.
In simpler terms: Holafly works like getting unlimited internet that slows down after you use a certain amount each day, while Truely works like having a smart global connection that automatically finds the best networks wherever you travel.

The comparison reveals that while Holafly excels in traditional unlimited eSIM offerings, Truely's revolutionary technology provides superior convenience, coverage, and value through automated global connectivity.
The technology behind each provider explains why user experiences vary significantly, even when both claim "unlimited" data.
Holafly operates using conventional 1st generation eSIM technology that requires manual setup for each destination or region.
How Holafly's System Works:
The "Unlimited" Reality: Despite "unlimited" marketing, Holafly implements fair use policies with speed throttling. Independent testing shows speeds dropping from 7MB/s to under 1MB/s after approximately 3-5GB daily usage in many destinations.
Network Limitations: Each Holafly eSIM connects to predetermined partner networks in destination countries. If the chosen partner has poor coverage in specific areas, travelers have no alternative connectivity options.
Truely's Switchless™ system represents the first fundamental advancement beyond traditional eSIM limitations, providing universal global connectivity through a single eSIM installation.
How Truely's Innovation Works:
True Unlimited Policy: Truely provides 10GB daily high-speed data before reducing speeds to 512kbps - the most generous policy in the industry. The 512kbps speed remains sufficient for messaging, navigation, and basic browsing without complete service interruption.
Multi-Network Intelligence: Truely's system negotiates access to 700+ networks globally, automatically selecting the best available carrier based on signal strength, speed, and performance metrics in real-time.
Understanding true costs requires looking beyond marketing claims to examine real-world usage scenarios and hidden limitations.
Traditional Daily Plans: Holafly's pricing varies significantly by destination with unlimited data offerings:
| Duration | Europe | Asia | Americas | Value Assessment |
|---|---|---|---|---|
| 1 Day | $6.90 | $6.90-11.90 | $5.90-11.90 | Expensive for short trips |
| 7 Days | $24.90 | $34.90-63.90 | $29.90-54.90 | Moderate weekly value |
| 15 Days | $44.90 | $64.90-89.90 | $54.90-84.90 | Better per-day rates |
| 30 Days | $74.90 | $99.90-139.90 | $84.90-119.90 | Best traditional value |
New Monthly Subscription (Holafly Plans):
The Throttling Reality: Despite "unlimited" marketing, users report significant speed reductions after 3-5GB daily usage in many destinations, impacting data-intensive activities like video calls and streaming.
Straightforward Daily Pricing: Truely offers the most competitive rates with true unlimited data:
| Duration | Global Daily Rate | True Data Policy | Additional Benefits |
|---|---|---|---|
| Daily | $2.50-5.52 | 10GB full speed, then 512kbps unlimited | No throttling anxiety |
| Weekly | $17.50-38.64 | 70GB full speed minimum | Multi-network access |
| Monthly | $77-166 | 300GB+ full speed | Automatic global expansion |
Honest Fair Use Policy: Truely's 10GB daily allowance covers 99% of travel usage scenarios. After reaching the daily limit, service continues at 512kbps - still functional for essential travel applications without complete service interruption.
No Hidden Costs: Truely's pricing includes unlimited hotspot sharing, automatic network switching, and global coverage without additional fees or upgrade requirements.
Both providers support the same range of eSIM-compatible devices, but setup experiences differ dramatically.
Device Compatibility: Most flagship smartphones manufactured since 2018 support eSIM technology from both providers:
| Device Type | First eSIM Support | Key Models | Compatibility Check |
|---|---|---|---|
| iPhone | iPhone XS/XR (2018) | iPhone XS through 16 series, iPhone SE (2nd & 3rd gen) | Settings > General > About > Look for "EID" |
| Android | Google Pixel 2 (2017) | Pixel 3+, Samsung Galaxy S20+, flagship models 2019+ | Settings > About Phone > Look for "EID" or dial *#06# |
| Smartwatch | Apple Watch Series 3 (2017) | Apple Watch 3+, Samsung Galaxy Watch, Google Pixel Watch | Check manufacturer specs |
| Tablet | iPad Pro 9.7" (2016) | Various iPad models, Android tablets from major brands | Check manufacturer specs |
Quick Compatibility Test: For iPhone: Go to Settings > General > About and look for "Digital SIM" or "EID." For Android: Go to Settings > About Phone and look for "EID" or dial *#06#. If an EID is present, your device supports eSIM from both providers.
The setup experience reveals the fundamental difference between traditional and revolutionary eSIM technology.
Standard Setup Process (5-15 minutes per destination):
Switchless™ Setup (1 minute total):
That's the complete process. No apps, no QR codes, no configuration, no technical knowledge required.
Network access and coverage quality differ significantly between single-carrier and multi-network approaches.
Partner Dependencies: Holafly eSIMs connect to specific partner carriers in each destination country:
