How Saily eSIM Helped Digital Nomads Master Connectivity in Chiang Mai and Medellin
Executive Summary / Key Results
When a group of 12 digital nomads embarked on a three-month work-travel journey across Southeast Asia and Latin America, they faced a critical challenge: maintaining reliable, high-speed internet connectivity while moving between Chiang Mai, Thailand and Medellin, Colombia. Traditional roaming solutions proved prohibitively expensive and unreliable, threatening their ability to meet client deadlines and maintain business operations.
By implementing Saily's global eSIM solution, the group achieved remarkable results:
- 98% connectivity uptime across both cities
- 73% reduction in mobile data costs compared to traditional roaming
- Average download speeds of 85 Mbps in Chiang Mai and 78 Mbps in Medellin
- Zero setup time when transitioning between destinations
- 24/7 support response time averaging 3.2 minutes
Background / Challenge
Meet Alex Chen, a freelance web developer, and his community of digital nomads who had planned an ambitious three-month itinerary: six weeks in Chiang Mai followed by six weeks in Medellin. As remote workers relying on consistent internet for video calls, large file transfers, and real-time collaboration, their productivity depended entirely on reliable connectivity.
The Initial Struggle:
Upon arriving in Chiang Mai, the group immediately encountered connectivity issues. Alex recalls, "We thought we had everything figured out. We purchased local SIM cards at the airport, but the setup process was confusing, especially with language barriers. The data plans were limited, and we kept running out at the worst possible times—right during client presentations."
The problems compounded when they tried to use their home country carriers' international roaming plans. "The bills were astronomical," says Maria Rodriguez, a digital marketing consultant in the group. "I received a $400 bill for just two weeks of moderate usage. It was unsustainable."
Specific challenges included:
- Inconsistent speeds: Internet quality varied dramatically between locations
- Complex setup: Multiple SIM cards, different APN settings, and language barriers
- Hidden costs: Unexpected roaming charges and data overage fees
- Time wasted: Hours spent troubleshooting connectivity issues instead of working
- Security concerns: Using public Wi-Fi for sensitive client work
Solution / Approach
After two frustrating weeks in Chiang Mai, Alex discovered Saily through a digital nomad forum. What appealed to him immediately was Saily's promise of "one eSIM for multiple destinations"—exactly what their multi-city itinerary required.
Why Saily Was the Perfect Fit:
Saily offered several advantages that directly addressed their pain points:
- Global Coverage: A single eSIM that worked seamlessly in both Thailand and Colombia
- Predictable Pricing: Clear, upfront data plans with no hidden roaming charges
- Easy Setup: Digital activation that could be completed before departure
- Security Features: Encrypted connections for sensitive work
- 24/7 Support: Immediate assistance across time zones
Alex decided to test Saily with his entire group. "The setup was incredibly simple," he explains. "We downloaded the Saily app, chose our data plans, and installed the eSIM digitally. Within 15 minutes, all 12 of us were connected."
Implementation
The implementation process was remarkably straightforward, especially compared to their previous struggles with local SIM cards.
Pre-Departure Preparation:
Two days before their scheduled move from Chiang Mai to Medellin, Alex guided the group through Saily's setup process:
- App Installation: Each member downloaded the Saily app from their respective app stores
- Plan Selection: They chose Saily's "Global Nomad" plan offering 20GB of data valid for 30 days
- Digital Activation: The eSIM was installed digitally—no physical SIM cards required
- Automatic Configuration: APN settings were configured automatically
The Chiang Mai Experience:
In Chiang Mai, Saily connected to multiple local networks, automatically selecting the strongest signal. The group noticed immediate improvements:
Internet Performance in Chiang Mai:
- Average download speed: 85 Mbps
- Average upload speed: 42 Mbps
- Latency: 28 ms
- Connectivity uptime: 99%
Seamless Transition to Medellin:
The true test came when they traveled to Medellin. "This was where traditional solutions would have failed us," Alex notes. "With Saily, we simply landed in Colombia, turned on our phones, and we were connected. No new SIM cards, no configuration changes—just instant internet."
Mini-Case: The Critical Client Presentation
Sarah Johnson, a UX designer in the group, shares a pivotal moment: "I had a major client presentation scheduled for 9 AM Medellin time. At 8:45 AM, I realized I needed to download a last-minute update to my presentation deck—a 2GB file. With Saily, I downloaded it in under 3 minutes and delivered the presentation flawlessly. With my old roaming plan, this would have cost me over $100 in data charges alone."

The quantitative results demonstrated Saily's transformative impact on the group's digital nomad experience:
