5G and eSIMs in 2026: which providers actually deliver
Marketing says 5G; reality says "5G icon, 4G speed". Here's how to tell which provider gets you the real thing.
Five years after the 5G rollout hype, most travel eSIMs still attach to 4G in practice. The reasons are mostly contractual (the wholesale partner restricts 5G to its retail customers), occasionally technical (no 5G core support on the partner SIM profile).
Providers we've confirmed deliver 5G in 2026
- Ubigi — by far the broadest 5G footprint. Routes through Transatel which has direct deals with all four US majors, most EU carriers, NTT Docomo and Singtel.
- Airalo — 5G on the newer "Discover" and country packs; older packs grandfathered to 4G.
- Holafly — 5G in EU, US, Japan, Korea. Not yet in SEA.
Providers usually capped at 4G
- Redteago — partner-dependent; their cheaper bundles ride 4G.
- Most "local prepaid SIM bought as eSIM" listings — they're the wholesale tier, 5G is reserved for retail prepaid.
How to verify before you buy
- Listing should explicitly say "5G" — if it says "LTE", assume 4G.
- Check the listed APN. 5G profiles typically use an NR APN string. If only "internet" is listed, you're probably on 4G.
- After install, dial *#*#4636#*#* on Android (engineer mode) or use Field Test on iPhone. The radio band tells you what you're actually attached to.
Does it matter
For maps, messaging, browsing: no. 4G is already plenty fast.
For tethering a laptop in a coffee shop, streaming 4K, video calls in a noisy place: yes. 5G's 4× throughput and 1/3 latency are noticeable.
9eSIM and 5G
The card itself is 5G-capable. Whatever profile you load decides what radio bands you get. So if you swap from Airalo (5G) to a cheap Redteago bundle (4G) on the same chip, you'll see speed drop until you switch back. It's the profile, not the card.
