Many eSIM providers charge a premium for 5G plans. Is it worth paying more? The honest answer: it depends entirely on what you're doing and where you're going. Here's the actual breakdown.
5G vs 4G Speeds — Real World Travel Numbers
| Generation | Typical Speeds | Peak Speeds |
|---|---|---|
| 4G LTE | 20–100 Mbps | 150–300 Mbps |
| 5G Sub-6 GHz | 100–400 Mbps | 1–2 Gbps |
| 5G mmWave (dense urban) | 500–2000 Mbps | 3–5 Gbps |
The numbers look dramatic. But what do these speeds actually mean for travel use?
Activities That Feel Identical on 4G and 5G
- ✅ Google Maps navigation — needs less than 1 Mbps
- ✅ WhatsApp messages and voice calls — needs less than 0.1 Mbps
- ✅ Instagram browsing — 5–10 Mbps is more than enough
- ✅ Email and web browsing — 4G is more than fast enough
- ✅ Grab/Uber booking — minimal data requirement
- ✅ Google Translate camera — works identically on both
Activities Where 5G Makes a Real Difference
- 🎬 4K video upload to Instagram/TikTok: 5G uploads a 1-minute 4K clip in seconds vs 30–60 seconds on 4G. Content creators notice this immediately.
- 💻 Hotspot for laptop (large file transfers): Downloading a 2GB file in 30 seconds (5G) vs 3–4 minutes (4G).
- 📹 Live streaming video: 5G handles 4K live streaming without buffering. 4G can do 1080p reliably but 4K can stutter on congested networks.
- ☁️ Cloud backup (large photo libraries): Syncing 500 photos to Google Photos overnight — 5G completes it faster.
Where 5G Coverage Actually Exists (Travel Destinations)
| Destination | 5G Coverage | Where You'll Actually Get 5G |
|---|---|---|
| South Korea | ✅ Excellent | All major cities, even subway |
| Japan | ✅ Good | Tokyo, Osaka, Kyoto city centres |
| Singapore | ✅ Excellent | Nationwide |
| USA | ✅ Good in cities | Major city centres |
| UK | ✅ Good | London, Manchester, Birmingham |
| Germany | ✅ Growing | Berlin, Munich, Hamburg |
| Thailand | ⚠️ Limited | Bangkok main areas only |
| Vietnam | ⚠️ Emerging | Hanoi and HCMC centres |
| Rural everywhere | ❌ Mostly 4G | Any rural destination is 4G |
The Honest Verdict
Buy 5G eSIM if you are:
- A content creator uploading 4K video daily
- A remote worker transferring large files
- Spending most time in a 5G-dense city (Seoul, Singapore, Tokyo)
- Live streaming your travel
4G LTE is completely sufficient if you are:
- A normal tourist using Maps, messaging, social media browsing
- Traveling to rural areas (where 5G doesn't exist anyway)
- Prioritizing data quantity over speed (more GB for the money)
- Going to destinations with limited 5G (Southeast Asia, most of Africa/Latin America)
For most travelers: buy the most data you can afford on 4G. The speed is irrelevant if you run out in 5 days.
