This page gathers everything we publish as data rather than advice: price tables computed from the live catalogue, network lists we can verify, the device list, and explainers on how roaming data actually travels. Each entry says where its information comes from.

Explainers behind the data
How a travel eSIM's data actually gets routedAn eSIM profile belongs to its issuing network, not the country you happen to be standing in. This walks through where data really travels: authentication, the gateway that hands out your IP address, and why a website can end up thinking you are somewhere else.Baca selengkapnya Why a website thinks you are in another country on a travel eSIMYour map app has the right city, but some website is convinced you are somewhere else entirely. That is not a broken phone — it is two different location systems disagreeing with each other.Baca selengkapnya Mobile frequency bands explained: why some phones catch a weaker signalInstalling an eSIM says nothing about whether your phone supports the frequency bands a local network actually runs on. Here is what a band is, how low, mid and high bands differ, and how to check your exact model before you travel.Baca selengkapnya Latency and ping on a travel eSIM: why fast data can still stutterDownload speed and latency are not the same measurement. This guide explains what ping actually is, where the delay along the path comes from, why some roaming setups route traffic to a gateway in another country, and how to read a speed test result abroad without fooling yourself.Baca selengkapnya Refurbished and imported phones: what to check before you rely on eSIMA refurbished or imported handset can be a good deal, but the model sold in one market is not always the model sold in yours. Here is what to verify about eSIM hardware, carrier lock and the previous owner's accounts before you buy.Baca selengkapnya Bagaimana sebenarnya jaringan mitra roaming bekerjaMemahami jaringan mana yang Anda gunakan, dan alasannya, membuat pemecahan masalah jauh lebih terarah.Baca selengkapnya 3G, 4G, dan 5G: apa arti perbedaannya bagi pelancongYang memengaruhi Anda bukan angkanya, melainkan apa yang didukung paket dan jaringan lokal.Baca selengkapnya Apa yang sebenarnya menentukan kecepatan seluler Anda di luar negeriKecepatan di dunia nyata adalah gabungan beberapa faktor, yang sebagian besar tidak dikendalikan oleh paket apa pun.Baca selengkapnya Aturan registrasi SIM di luar negeri: apa yang perlu dipahamiBanyak negara mewajibkan registrasi SIM lokal, yang secara langsung membentuk pilihan pelancong.Baca selengkapnya
What a record goes through before it is published
- Draft
- Fact check against the source
- Written in all three core languages
- Native reader review
- Published with its check date
- Re-checked, or marked outdated
Records that have not passed every step stay in our system but are not shown. Where a fact has not been confirmed by an official source, we say it is not verified rather than guess.
What we do not publish
- Speed or ping figures we did not measure ourselves.
- Claims that a network or plan is the best, without data behind them.
- Regulations quoted from blogs or other sellers instead of the authority itself.
If you cite any of these pages, cite the updated or checked date shown on it as well: prices, networks and rules change.
FAQ
Where does the data on this page come from?+
Three places: the catalogue of packages we actually sell (prices and networks), documents that manufacturers and authorities publish themselves (devices and regulations), and industry standards such as 3GPP and IETF documents (the technical explainers). Each page lists its own sources.
Do you publish real speed or ping measurements?+
Not yet. We do not publish figures we have not measured ourselves. When we do, every result will carry its date, place, device, the network it attached to and the method, so it can be repeated.
What if something here is wrong?+
Tell us through the corrections page. We re-check against the original source and correct the page.
