Cities With the Fastest WiFi for Remote Work

Jan 18, 2026 10 min read

Internet speed isn't a nice-to-have for remote workers. It's the single thing that determines whether a city is workable or not. A gorgeous beach town with 5 Mbps download is a vacation, not a workplace.

We've spent the past year testing WiFi in over 50 cities using Sour Mango's WiFi Speed Test — in cafes, coworking spaces, apartments, and hotel lobbies. These are the 15 cities that consistently delivered the fastest, most reliable connections.

This isn't based on national averages or ISP marketing claims. It's based on real-world tests in the places nomads actually work from.

Testing WiFi speeds in a coworking space

How We Tested

Every city was tested across at least 10 locations — cafes, coworking spaces, and residential apartments. We used Sour Mango's WiFi Speed Test to capture download speed, upload speed, and latency at each spot. All results are saved in the app, so you can compare your own tests city by city.

We weighted the rankings by three factors:

  1. Median download speed across all tested locations
  2. Consistency — a city with 200 Mbps in coworking but 10 Mbps in cafes scores lower than one with steady 100 Mbps everywhere
  3. Cafe/coworking reliability — how often speeds dropped below 25 Mbps during peak hours

1. Seoul, South Korea

South Korea has the fastest internet on the planet, and it's not even close. Every cafe, every subway station, every convenience store — the WiFi is absurdly fast.

The only downside is the cost of living is higher than Southeast Asia. But if internet speed is your top priority, nowhere beats Seoul.

Pro tip: Run Sour Mango's WiFi Speed Test at any Korean cafe — you'll regularly see numbers that would embarrass most European offices. Your results save automatically so you can track speeds across neighbourhoods.

2. Singapore

Singapore treats internet infrastructure like a national priority. Residential fibre averages 500+ Mbps, and public WiFi through Wireless@SG covers most of the island.

Expensive to live in, but if you're passing through or doing a short stint, the internet will never let you down.

3. Bucharest, Romania

The surprise entry that shouldn't be a surprise anymore. Romania invested heavily in fibre infrastructure, and Bucharest is reaping the benefits. Gigabit connections cost less than a nice dinner.

Bucharest is also wildly affordable compared to Western Europe. The combination of gigabit fibre for $10/month and $500 rent makes it one of the best value cities for remote workers.

In Sour Mango: Check the Destinations tab for Bucharest's full cost breakdown — you'll see why it keeps climbing the nomad rankings.

4. Bangkok, Thailand

Thailand's internet has quietly become world-class. Bangkok condos come standard with 300-500 Mbps fibre, and 5G coverage blankets the city.

Mobile data is the secret weapon here — 100GB 5G plans for $10/month mean you always have a fast backup.

5. Tallinn, Estonia

Estonia built its entire identity around digital infrastructure, and it shows. E-residency, digital government, and internet speeds that rival the Nordics at a fraction of the cost.

Cold winters keep costs down. A one-bedroom in the centre runs about $600-$800/month — affordable by European standards.

6. Taipei, Taiwan

Taiwan's fibre network is extensive and cheap. Taipei is a dream for remote workers who need consistent, fast internet without paying Singapore prices.

Pro tip: Use Sour Mango's WiFi Speed Test at Taipei's legendary cafes before settling in. Louisa Coffee and cama cafe locations vary wildly — test first, then commit.

7. Lisbon, Portugal

Lisbon's internet has improved dramatically in the last few years. NOS and MEO fibre networks now cover most of the city, and coworking spaces have upgraded their infrastructure.

The NIF tax number and rental market are bigger headaches than the WiFi at this point.

8. Barcelona, Spain

Spain's fibre rollout has been aggressive, and Barcelona benefits. Most apartments come with 300+ Mbps options, and the coworking scene is massive.

9. Tokyo, Japan

Japan's internet is fast and reliable, as you'd expect. The challenge isn't speed — it's finding workspaces. Japanese cafes aren't always laptop-friendly, and public WiFi requires registration.

Get a pocket WiFi or eSIM immediately. Sour Mango's WiFi Speed Test will help you sort the good spots from the tourist traps.

10. Prague, Czech Republic

Central Europe's dark horse. Prague has excellent fibre coverage and a growing coworking scene, all at prices well below Western Europe.

11. Dubai, UAE

Dubai invested billions in telecom infrastructure, and the speeds reflect it. The downside: VPN restrictions can add latency and complicate certain tools.

12. Mexico City, Mexico

CDMX has pockets of excellent internet, but consistency is the issue. Fibre-connected coworking spaces are blazing fast. Random cafes in Roma can be painfully slow.

This is exactly where Sour Mango's WiFi Speed Test earns its keep. In cities with variable speeds, testing before you sit down saves hours of frustration. Build your personal map of reliable spots and share them with your Tribe.

13. Budapest, Hungary

Hungary's internet infrastructure punches above its weight. Budapest has fast, cheap fibre and a thriving coworking scene that caters to nomads.

At $15/month for 500 Mbps home internet, Budapest might be the best speed-per-dollar in Europe.

14. Kuala Lumpur, Malaysia

KL's internet has improved significantly. TIME and Unifi fibre networks cover most of the city, and coworking spaces are well-equipped.

15. Medellín, Colombia

Medellín's internet has come a long way. EPM's fibre network covers most of El Poblado and Laureles, and the coworking scene is excellent for the price.

The Bottom Line

Internet speed alone doesn't make a city great for remote work — but it's the non-negotiable foundation. A city can have perfect weather, cheap rent, and incredible food, but if you can't hold a video call without buffering, none of it matters.

Our top three overall picks:

  1. Seoul — if raw speed is your priority and you can handle the cost
  2. Bucharest — best speed-to-cost ratio in the world, and it's not close
  3. Bangkok — the complete package: fast internet, low cost, great food, nomad visa

How to Test Any City Yourself

Don't take our word for it. When you arrive in a new city:

  1. Open Sour Mango's WiFi Speed Test at every cafe, coworking space, and apartment you visit
  2. Results save automatically with location data — you're building your personal WiFi map
  3. Compare speeds across neighbourhoods to find your ideal work zone
  4. Share your tested spots with your Mates and Tribes so others don't waste time on dead connections

The difference between a productive day and a frustrating one often comes down to 30 seconds of testing before you order that coffee.

In Sour Mango: Use Destinations to compare cities before you fly. Every destination page shows internet speed data, coworking options, and cost of living — so you can shortlist cities that match your minimum speed requirements. Pair it with the Visa Requirements checker to make sure you can actually stay long enough to enjoy that gigabit fibre.
