Background / Challenge
Sarah Chen, a freelance graphic designer and digital nomad, embarked on a 3-month European tour through Portugal, Spain, France, and Italy. Her work required consistent internet access for client meetings, large file transfers, and real-time collaboration. Despite purchasing an eSIM from a popular provider, she encountered persistent connectivity issues that threatened both her professional commitments and travel experience.
"I thought switching to an eSIM would solve all my connectivity problems," Sarah recalled. "But in reality, I found myself constantly struggling with weak signals, dropped video calls, and painfully slow upload speeds. In Lisbon, I missed an important client presentation because my connection failed completely. In Barcelona, it took me 45 minutes to upload a 50MB design file that should have taken seconds."
Sarah's specific challenges included:
- Inconsistent signal strength: Her phone showed full bars one moment and no service the next
- Unreliable network quality: Even with signal, data speeds fluctuated wildly
- Location-dependent issues: Connectivity varied dramatically between neighborhoods in the same city
- Limited troubleshooting knowledge: She didn't know how to properly diagnose eSIM connection problems
- Time-sensitive work impact: Client deadlines couldn't wait for better connectivity
These issues weren't just inconvenient—they directly threatened her income and professional reputation. Sarah estimated she was losing 10-15 hours per week troubleshooting connectivity or waiting for files to transfer.
Solution / Approach
Frustrated but determined, Sarah decided to systematically address her eSIM connectivity issues. She switched to Saily's eSIM service and implemented a comprehensive approach to monitoring and optimizing her network connection abroad.
Sarah's solution involved three key components:
1. Proactive Signal Strength Monitoring Instead of waiting for problems to occur, Sarah learned to regularly check her eSIM signal strength using built-in phone diagnostics. She discovered that different locations within the same city could have dramatically different signal quality, and that certain times of day affected network congestion.
2. Systematic Network Quality Assessment Sarah implemented regular speed tests using free apps like Speedtest by Ookla to measure actual data performance rather than relying on signal bars alone. She created a simple tracking system to identify patterns and optimal locations for important work tasks.
3. Strategic Provider Features Utilization With Saily's 24/7 support, Sarah learned to leverage features like manual network selection and APN configuration adjustments. She also utilized Saily's data usage notifications to avoid throttling and ensure optimal speeds throughout her billing cycle.
"The turning point came when I realized I needed to be proactive rather than reactive," Sarah explained. "Instead of just accepting poor connectivity, I learned how to measure it, understand it, and improve it. Saily's support team was instrumental in teaching me the technical aspects I needed to know."
Implementation
Sarah implemented her solution through a practical, step-by-step process that any traveler can replicate:
Week 1: Baseline Assessment During her first week in Porto, Portugal, Sarah established performance baselines. She used her phone's built-in field test mode (dialing 3001#12345# on iPhone or using the secret menu on Android) to check actual signal strength in decibels rather than relying on bars. She discovered that what appeared as "2 bars" on her display actually represented a -105 dBm signal—borderline for reliable data service.
Week 2: Pattern Identification Sarah created a simple tracking system using a notes app on her phone:
| Location | Time | Signal (dBm) | Download Speed | Upload Speed | Latency | Notes |
|---|---|---|---|---|---|---|
| Porto Airbnb | 9 AM | -98 | 15 Mbps | 3 Mbps | 45 ms | Good for emails |
| Porto Cafe | 2 PM | -112 | 2 Mbps | 0.5 Mbps | 120 ms | Avoid video calls |
| Lisbon Hotel | 11 AM | -89 | 42 Mbps | 18 Mbps | 28 ms | Excellent for all work |
This data revealed clear patterns: morning hours generally offered better connectivity, certain neighborhoods had superior infrastructure, and indoor locations often degraded signal strength by 20-30%.
Week 3: Optimization Techniques Armed with data, Sarah implemented specific optimizations:
- Manual network selection: Instead of automatic network switching, she manually selected the strongest local carrier in each location
- APN configuration: With Saily's guidance, she optimized her Access Point Name settings for each country
- Strategic timing: She scheduled bandwidth-intensive tasks for optimal connectivity windows
- Location awareness: She identified and frequented "connectivity hotspots" in each city
Week 4: Advanced Troubleshooting For persistent issues, Sarah learned advanced techniques like resetting network settings, toggling airplane mode to force reconnection, and using Saily's live chat support for real-time assistance during critical work moments.
Results with Specific Metrics
Sarah's systematic approach yielded impressive, measurable results over her 3-month European journey:

The peace of mind was invaluable."
Mini-Case: Barcelona Client Presentation
During her second month, Sarah faced a critical test: presenting design concepts to a major client via video conference from Barcelona. Using her new knowledge, she:
- Pre-scouted locations the day before, identifying a co-working space with -85 dBm signal strength
- Conducted speed tests at the exact time of her scheduled meeting
- Configured her device with optimal APN settings for Spanish networks
- Had Saily support on standby via live chat during the presentation
The result? A flawless 90-minute presentation with HD video, real-time screen sharing, and instant file transfers. The client commented on the exceptional call quality, unaware Sarah was connecting from abroad.
Key Takeaways
Sarah's experience offers valuable lessons for any traveler using eSIMs abroad:
1. Signal Bars Lie Your phone's signal bars provide a simplified, often inaccurate representation of actual signal strength. Learning to check real signal measurements in decibels (-50 to -120 dBm, with higher numbers being better) provides much more reliable information.
2. Location Matters More Than You Think Connectivity can vary dramatically within small geographic areas. Moving just a few blocks or changing floors in a building can significantly impact signal quality. Always test multiple locations for important tasks.
3. Proactive Monitoring Beats Reactive Troubleshooting Regularly checking signal strength and network quality helps identify patterns and prevent problems before they impact your work. Consider it essential travel preparation, like checking the weather forecast.
4. Provider Support is Crucial Not all eSIM providers offer the same level of support. Saily's 24/7 live chat proved invaluable for Sarah, providing real-time assistance during critical moments. When choosing an eSIM provider, prioritize those with responsive, knowledgeable support teams.
5. Simple Tools Yield Powerful Insights Free apps like speed test utilities and basic note-taking for tracking performance patterns require minimal effort but provide maximum insight into your connectivity experience.
