Your phone becomes a portable WiFi router through hotspot tethering. For remote workers, this transforms eSIM data into laptop connectivity anywhere with cellular signal. But not all eSIM plans allow tethering, and not all setups perform equally.
This guide covers making hotspot tethering work reliably with eSIM—from choosing providers that allow it to optimizing your setup for video calls and heavy work.
This article is part of our complete digital nomad connectivity guide, covering everything you need for reliable connectivity anywhere.
The Tethering Reality
What Hotspot Tethering Actually Does
When you enable hotspot, your phone creates a local WiFi network. Your laptop connects to this network, and your phone routes that traffic through its cellular connection—in this case, your eSIM data plan.
Simple in theory. In practice, several factors determine whether this works smoothly or frustratingly.
Why Tethering Matters for Remote Work
- Backup connectivity when hotel WiFi fails
- Primary connection in areas without reliable WiFi
- Security through your own encrypted connection
- Flexibility to work from anywhere with cellular signal
Which eSIM Providers Allow Tethering?
This is the critical question. Not all eSIM providers permit hotspot use, and policies aren't always clear.
Guaranteed Tethering
| Provider | Hotspot Policy | Notes | |----------|----------------|-------| | Nomad eSIM | Allowed on all plans | Primary differentiator | | Saily | Allowed on all plans | No restrictions | | aloSIM | Allowed on all plans | Included by default |
Conditional Tethering
| Provider | Hotspot Policy | Notes | |----------|----------------|-------| | Airalo | Varies by plan | Check plan details before purchase | | Holafly | Generally restricted | Most unlimited plans block hotspot |
How to Check Before Buying
Before purchasing any eSIM plan for tethering:
- Read plan details - Look for "hotspot" or "tethering" mentions
- Check FAQ - Provider FAQs often clarify policies
- Contact support - When unclear, ask directly

Position matters - Place your phone where cellular signal is strongest. Near windows typically works best indoors.
Minimize phone use - While tethering, avoid heavy phone activities that compete for bandwidth.
Optimizing Hotspot Performance
USB Tethering vs WiFi Hotspot
WiFi hotspot is convenient but not always optimal. USB tethering offers advantages:
USB Tethering Benefits:
- More stable connection
- Charges phone simultaneously
- Often faster speeds
- Lower latency
How to USB Tether:
- Connect phone to laptop via USB cable
- On phone: Enable USB tethering in settings
- Laptop should detect network automatically
USB tethering works on both Mac and Windows, though Mac may require initial setup.
Band Selection and Signal
Your hotspot speed depends entirely on your phone's cellular connection. To maximize performance:
Find good signal - Check signal strength indicator. Three or more bars provides reliable tethering.
Try different locations - Moving a few meters can significantly change signal quality.
Avoid interference - Metal structures, thick walls, and basements typically have worse signal.
Consider time of day - Cellular networks can be congested during peak hours.
Managing Data Usage
Laptops consume data differently than phones. Common data drains while tethering:
| Activity | Approximate Data Use | |----------|---------------------| | Video call - 1 hour | 1-2 GB | | Web browsing - 1 hour | 100-300 MB | | Email - 1 hour | 20-50 MB | | Cloud sync - varies | Can be significant | | OS updates | Often several GB |
Reduce unnecessary data use:
- Disable automatic updates on laptop while tethering
- Pause cloud sync for Dropbox, Google Drive, etc.
- Use compressed video for calls when possible
- Close background apps that might sync or update
Tethering for Video Calls
Video calls are the most demanding use case for hotspot tethering. Success depends on your cellular connection quality.
Minimum Requirements
| Call Type | Minimum Speed | Recommended | |-----------|---------------|-------------| | Audio only | 0.5 Mbps | 1+ Mbps | | Video - standard | 1.5 Mbps | 3+ Mbps | | Video - HD | 3 Mbps | 5+ Mbps | | Screen sharing | 2 Mbps | 4+ Mbps |
Testing Before Important Calls
Before critical meetings:
- Speed test - Run a speed test on your laptop while tethered
- Test call - Make a brief test call to verify quality
- Backup plan - Know where nearby WiFi exists if needed
- Battery check - Ensure phone is charged or plugged in
During the Call
Keep video off initially - Start with video off to verify connection, then enable if stable.
Monitor signal - Watch your phone's signal indicator throughout the call.
Have audio backup - Be ready to switch to audio-only if video struggles.
Close other tabs - Minimize bandwidth competition during the call.
Troubleshooting Common Issues
Hotspot Won't Enable
Check eSIM plan - Some plans explicitly block tethering. Verify your plan allows it.
Restart phone - Power cycle sometimes resolves activation issues.
Check data balance - Ensure you have remaining data on your plan.
Contact provider - If plan should allow tethering but doesn't work, contact support.
Connection Drops Frequently
Signal issue - Move to area with better cellular coverage.
Phone overheating - Phones throttle when hot. Let it cool or improve ventilation.
Interference - Move away from other electronics or metal structures.
Try USB tethering - More stable than WiFi hotspot for sustained use.
Slow Speeds
Congested network - Try again during off-peak hours.
Data throttling - Some plans throttle after certain usage. Check your plan terms.
Phone limitations - Older phones may have slower cellular modems.
