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
Read reviews - Other users report tethering experiences

For a detailed comparison of providers and their tethering policies, see our guide to the best eSIMs for digital nomads.

Setting Up eSIM Tethering

Step 1: Install and Activate eSIM

Before you need tethering, ensure your eSIM is working:

Download your chosen provider's app
Purchase a plan that allows tethering
Follow installation instructions
Verify the eSIM connects to cellular data
Test basic internet on your phone

Step 2: Enable Hotspot on Your Phone

iPhone:

Settings → Cellular → Personal Hotspot
Toggle "Allow Others to Join"
Note the WiFi password displayed

Android:

Settings → Network & Internet → Hotspot & Tethering
Toggle "WiFi Hotspot"
Tap to configure name and password

Step 3: Connect Your Laptop

Open WiFi settings on your laptop
Find your phone's hotspot network name
Enter the password
Verify connection works

Step 4: Optimize for Work

Once connected, optimize for reliable performance:

Keep phone charged - Hotspot drains battery quickly. Keep your phone plugged in or use a power bank.

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.

Background usage - Close apps on both phone and laptop consuming bandwidth.

Laptop Won't Connect

Forget and reconnect - On laptop, forget the hotspot network and reconnect fresh.

Check password - Verify you're entering the hotspot password correctly.

Restart hotspot - Disable and re-enable hotspot on phone.

Try USB instead - WiFi hotspot issues don't affect USB tethering.

Battery Management

Hotspot drains phone battery quickly—often 15-25% per hour under active use.

Keep Phone Powered

Best approach: Keep phone plugged into power while tethering. USB tethering to laptop accomplishes this automatically.

Power bank - If outlet isn't available, a quality power bank keeps you working. See our portable power guide for recommendations.

Minimize Drain

Lower screen brightness - Screen is a major battery consumer.

Disable unnecessary radios - Turn off Bluetooth and NFC while tethering.

Close background apps - Reduce other phone activity during tethering.

Use USB tethering - Charges phone while providing connection.
