Loved by travellers
5-star reviews from people who actually travel.
"Worked the moment I landed in Tokyo. Setup took 90 seconds and the rate per GB was less than half my carrier's roaming pack."
"Latency around 100ms in Dallas, full LTE in Mexico City. Topping up takes literally 10 seconds. Best travel-data product I've used."
"Reception in the Netherlands was excellent — full speed, no drops on a 4-hour video call. Would recommend to any remote worker abroad."
FAQ
Everything we get asked, up front.
Does my balance ever expire?
No. Your balance stays in your account until you use it — no monthly burn, no auto-expiry. We don't reset balances at the end of a month or a year.
Will it work on my phone?
Any phone released after 2018 with eSIM support — that's every iPhone XR and newer, every Pixel 3 and newer, every Galaxy S20 and newer, plus most flagship Android phones from Xiaomi, Oppo, Huawei. We'll show compatibility before you buy.
How fast is the data?
Native 4G/5G speeds wherever the local carrier supports them. We use direct carrier integrations — no middleman throttling — so you get the same speed local subscribers get on supported tiers.
What about voice and SMS?
Today we focus on the global data travel eSIM — the fastest path to reliable roaming data. Voice/SMS add-ons may return later; use data-first apps (WhatsApp, Signal, FaceTime) in the meantime.
How do refunds work?
If your eSIM doesn't install or your device isn't compatible, contact support within 14 days for a full refund of unused balance. We don't refund consumed data — pay-as-you-go means you're only billed for what you actually use.
Is there an app I need to install?
No. The eSIM works through your phone's native cellular settings — no app, no profile installer, no third-party permissions. Manage balance and top-ups via your account on nxtlsim.com.
