You’re staring at a spinning wheel on Zoom, your Airbnb host is knocking, and your deadline is in 30 minutes. I’ve been there. Three years of remote work across 12 countries taught me one thing: hotel Wi-Fi is a liar.
I’ve burned through prepaid SIMs that stopped working after 10GB, portable hotspots that died at 3 PM, and more coffee shop connections than I care to count. Here’s what I learned, so you don’t have to learn it the hard way.
What Actually Matters for Video Calls and File Uploads
Most travel guides talk about “coverage” like it’s one number. It’s not. For remote work, you need three specific things:
- Low latency — under 50ms for stable Zoom/Teams calls. High latency makes you sound like a robot.
- Consistent upload speed — at least 5 Mbps for HD video. Download speed matters less than you think.
- No throttling after a data cap — many “unlimited” plans slow you to 128 kbps after 20GB. That’s unusable.
I test every connection with Speedtest by Ookla and Zoom’s built-in connection test before committing to a week of work somewhere. If ping spikes above 100ms during peak hours, I move.
The 3 PM Dropoff
Here’s a pattern I see everywhere: speeds are fine at 8 AM, then tank after lunch when everyone in the city wakes up. Local mobile networks get congested. A portable hotspot on a different carrier can save your afternoon.
SIM Cards: The Cheap Option That Can Bite You
Physical SIMs and eSIMs are the cheapest per-GB option. I’ve used Airalo, Google Fi, and local prepaid SIMs from Vodafone, Orange, and TIM.
| SIM Type | Cost per 10GB | Speed (typical) | Throttle after cap | Best for |
|---|---|---|---|---|
| Local prepaid (e.g., Vodafone Italy) | €10-€20 | 30-100 Mbps | Yes, often hard | Long stays in one country |
| Airalo eSIM (regional) | $12-$25 | 10-40 Mbps | Yes, after data runs out | Short trips, multiple countries |
| Google Fi (Flexible) | $10/GB | 20-50 Mbps | No, but slows after 15GB | US residents traveling frequently |
| Holafly (unlimited) | $30-$60 | 5-20 Mbps | Yes, after fair use (often 5-10GB) | Light users who hate counting GB |
The catch with SIMs: your phone becomes a hotspot. That drains battery fast. I killed a Pixel 7 battery in 4 hours doing a 2-hour Zoom call while hotspotting my laptop. Not fun.
Also, eSIMs don’t always support tethering. Check the fine print. Airalo’s regional eSIMs allow it, but some country-specific ones don’t. I learned this in Romania at 10 PM.
Portable Hotspots: More Expensive, More Reliable
After six months of SIM-only travel, I bought a GlocalMe G4 Pro ($199). It changed my workflow. Here’s why:
- Battery lasts 12-14 hours of mixed use. I charge it overnight and it survives a full workday.
- Connects up to 10 devices. My laptop, phone, and backup phone all on one network.
- No SIM swapping. It uses cloud SIM technology — you buy data plans through their app, and it switches carriers automatically.
The downsides? It costs $5-$15 per GB depending on region. That’s 3-5x more than a local SIM. And you have another device to carry and charge.
The $80 Alternative That Almost Works
The TP-Link M7350 ($80) is smaller and cheaper, but requires a physical SIM. That means you’re still hunting for prepaid SIMs in every country. I used this in Spain and Portugal — worked fine, but the battery only lasts 8 hours. By 4 PM I was hunting for power outlets.
When to Skip Both and Use Your Phone
Honestly? If you’re traveling for under a week, just use your phone as a hotspot. Most modern phones (iPhone 14+, Samsung S23+, Pixel 7+) support Wi-Fi 6 and 5G, which gives you enough speed for video calls.
The real issue is battery. I carry a 20,000 mAh power bank ($30 from Anker) when I rely on phone hotspotting. That gives me about 6 extra hours of tethering.
But if you’re staying somewhere for a month? Get a local SIM. If you’re hopping countries every week? Get a hotspot. There’s no universal winner.
The 5 Most Common Failures I’ve Seen
I’ve watched dozens of remote workers make these mistakes. Don’t be them.
- Buying “unlimited” data without reading the fair use policy. Holafly’s “unlimited” plans throttle after 5-10GB in most countries. You’ll hit that in one afternoon of video calls.
- Not testing the connection before a meeting. Speedtest takes 30 seconds. Do it before every call, not during.
- Assuming 4G is the same everywhere. In rural Portugal, 4G gave me 2 Mbps. In central Rome, 150 Mbps. Check coverage maps on OpenSignal or nPerf before booking accommodation.
- Not having a backup. One device = one point of failure. I carry a local SIM in my phone AND a hotspot. When the SIM fails, the hotspot saves me.
- Forgetting time zones and carrier maintenance. Many European carriers do network maintenance between 2 AM and 5 AM local time. If you’re working US hours from Europe, that’s your afternoon.
My Setup for 2026: The Hybrid Approach
After three years of trial and error, here’s what I carry:
- GlocalMe G4 Pro — primary connection. I buy 10GB regional plans for $50-$70. Lasts me 10-14 days of moderate use.
- Google Fi eSIM on my phone — backup. $10/GB, works in 200+ countries. Expensive but reliable.
- Anker PowerCore 20,000 mAh — charges both devices for a full day.
Total cost per month: about $100-$150 for data. That’s less than one night in a decent hotel. Worth every penny.
If I had to recommend one setup for most people: get a GlocalMe G4 Pro or Skyroam Solis X ($149) for the hotspot, and keep a local eSIM as backup. Skip the cheap hotspots that need physical SIMs — you’ll waste time hunting for prepaid cards.
What About 5G? Should You Care?
5G sounds great. In practice, it’s overkill for remote work. Video calls need 5-10 Mbps. Even fast 4G gives you 30-50 Mbps in cities. 5G adds speed you don’t need and drains battery faster.
The one exception: file uploads. If you regularly upload 1GB+ video files, 5G cuts that from 5 minutes to 30 seconds. For everything else, 4G is fine.
Most hotspots in 2026 support 4G LTE Cat6 or higher. That’s enough. Don’t pay extra for 5G unless you’re doing heavy uploads daily.
I’ve used the Netgear Nighthawk M1 ($300, 4G only) and the GlocalMe G4 Pro (4G only). Both handle everything I throw at them. The Nighthawk has better range — I can leave it in my room and work from the balcony. But it’s bigger and needs a SIM.
