Executive Summary / Key Results

- Zero security incidents across 5 countries in Asia
- 24/7 support response averaging under 5 minutes during emergencies
This case study demonstrates how international travelers can protect themselves from common data scams while enjoying reliable, affordable connectivity abroad.
Background / Challenge
Sarah had been traveling as a digital nomad for two years when she arrived in Bangkok. Like many travelers, she relied on local SIM cards for mobile data, believing they offered the best value. However, during her third week in Thailand, she purchased a "tourist SIM" from a street vendor that promised "unlimited data for 30 days" at just $25.
The first red flag appeared when the vendor insisted on cash payment only and provided no receipt. Within 24 hours, Sarah's data speed dropped to unusable levels. When she tried to contact the provider, the customer service number was disconnected. She eventually discovered she'd purchased a recycled SIM card with limited data that had already been mostly consumed by the previous owner.
This experience was just one of several data-related scams Sarah encountered:
| Scam Type | How It Works | Typical Cost | Frequency Among Travelers |
|---|---|---|---|
| Fake Unlimited Plans | Advertised as unlimited but throttled after minimal usage | $20-50 | 35% of travelers report experiencing this |
| Recycled SIM Cards | Previously used SIMs sold as new with limited remaining data | $15-40 | 22% encounter this scam |
| Hidden Roaming Charges | Local providers automatically connect to expensive networks | $100-500+ | 41% experience unexpected charges |
| Fake Wi-Fi Hotspots | Malicious networks designed to steal data | Data theft + potential financial loss | 18% have connected to suspicious networks |
Sarah's challenges were compounded by her work requirements. As a freelance graphic designer, she needed reliable internet for client meetings, file transfers, and project management. The data scams weren't just inconvenient—they threatened her livelihood.
Solution / Approach
After her Bangkok experience, Sarah researched secure alternatives and discovered Saily. What appealed to her was Saily's transparent pricing and security-first approach. Unlike local providers with questionable practices, Saily offered:
Pre-Travel Security Assessment Before her next trip to Vietnam, Sarah used Saily's free security checklist to identify potential risks. The assessment revealed that public Wi-Fi networks in her planned destinations had a 40% higher incidence of security issues compared to other regions.
Multi-Destination Protection Sarah planned to visit Vietnam, Cambodia, Laos, and Malaysia over three months. Saily's single eSIM covered all these countries with consistent security protocols, eliminating the need to purchase from multiple local providers with varying reliability.
Real-Time Monitoring Features Saily's app included data usage notifications and network security alerts. If Sarah connected to a suspicious network, she would receive an immediate warning—a feature that proved crucial in preventing potential data theft.
24/7 Security Support Perhaps most importantly, Saily offered round-the-clock live chat support with security specialists who could help identify and avoid scams in real-time.
Implementation
Sarah's transition to Saily followed a simple three-step process:
Step 1: Pre-Travel Setup (15 minutes) Before leaving for Vietnam, Sarah purchased Saily's Asia Pass directly through the app. The setup involved:
- Downloading the Saily eSIM profile
- Selecting her data plan (10GB for 30 days, with rollover option)
- Setting up automatic activation for her arrival date
- Configuring security preferences and notification settings
Step 2: Arrival and Activation (6 minutes) Upon landing in Hanoi, Sarah's phone automatically connected to Saily's partner network. The entire activation process took just 6 minutes, compared to the 2+ hours she typically spent finding reputable local vendors, verifying their legitimacy, and setting up new SIM cards.
Step 3: Ongoing Management Throughout her travels, Sarah used Saily's app to:
- Monitor data usage in real-time
- Receive security alerts about suspicious networks
- Top up data instantly when needed
- Access 24/7 support during a network issue in rural Cambodia
A concrete example of Saily's protection in action occurred in Siem Reap, Cambodia. While exploring ancient temples, Sarah received a notification: "Warning: The public Wi-Fi network 'AngkorFreeWiFi' has been reported for security issues. We recommend using your Saily mobile data instead." This alert potentially saved her from what security experts later confirmed was a phishing network designed to capture login credentials.

Key Takeaways
Sarah's experience highlights several crucial lessons for international travelers:
1. Research Before You Connect Local SIM cards might seem convenient, but they often come with hidden risks. Always verify provider legitimacy through multiple sources. For guidance on vetting providers, see our guide on how to research mobile providers abroad.
2. Transparency Beats "Bargain" Prices Scammers often use too-good-to-be-true pricing to lure travelers. Legitimate providers like Saily offer clear pricing without hidden fees. If a deal seems unusually cheap, it probably has undisclosed limitations.
3. Security Features Are Non-Negotiable Modern travelers need more than just data—they need protection. Features like network security alerts and encrypted connections are essential in today's digital landscape. Learn more about essential security features for travelers.
4. Support Availability Matters When you're in a foreign country facing connectivity issues, 24/7 support can mean the difference between a minor inconvenience and a major disruption. Sarah's ability to get immediate help in Cambodia prevented what could have been a work-stopping problem.
5. Consistency Across Borders Saves Time and Money Using a single provider for multiple destinations eliminates the repetitive setup process and reduces exposure to new scams in each country. For digital nomads like Sarah, this consistency is particularly valuable.
