About this guide
This site deals with the money side of travel connectivity: what data is spent on, which line spends it, and how to keep the bill predictable.
Simnavi is written for travellers who have already decided to use an eSIM and now want to avoid two specific outcomes: running out of data halfway through a trip, and finding charges on a home bill that nobody warned them about.
What the guide covers
Pages cover consumption by activity, the per-line nature of roaming settings, the four charge paths that reach a home tariff, methods for monitoring usage, and the fair-use and hotspot restrictions that decide whether a plan suits a working trip.
The treatment is deliberately mechanism-first. Once a reader understands that roaming is a permission attached to a line, and that data is routed to one line at a time, the individual menu labels become far less important.
Who it is for
Travellers who are price-conscious without being obsessive, including remote workers who need to know whether tethering is permitted before they buy. No provider is recommended and no price is quoted, because both change faster than an evergreen page can follow.
Limits
Data consumption depends on device, app version, video quality and network conditions, so every figure here is presented as an order of magnitude rather than a measurement. Actual charges depend on the tariff of the reader's own operator, which this site cannot see.
The site is independent and unsponsored, is not a telecommunications provider, and does not offer billing advice for a specific account. For a specific charge, the operator's invoice and price list are the authoritative documents.
Corrections and suggestions are welcome once the operator has configured a contact address. The contact page explains what information to include.
