01 / What to buy
Their best plans right now
Their own plans, ranked on price per gigabyte rather than on headline price. Two that cover more than one country and two that cover a single market, so you can see how differently the same provider prices breadth.

02 / The catalogue
What SimBye publishes
Read from their live catalogue on a schedule. Percentages are shares of their plan-market coverage, and a blank figure means they do not publish it.
717 distinct plans reach 157 markets, which is 1 327 plan-market combinations. A multi-country bundle counts as one plan here, not one per country it covers.
03 / Against the field
How their pricing compares
Typical price per gigabyte across each provider's whole catalogue. Lower is better, and this is the figure marketing never leads with.

We keep every price we read: 720 observations of this provider's plans so far, over 6 days. That is not yet long enough to call a trend, so we do not publish one. A price movement needs at least 14 days of history behind it before it means anything, and this section fills itself in once the window is wide enough.
04 / Our code
15% off at SimBye
A code appears here only once a person has checked it and recorded the date. Where one exists it applies at the provider's own checkout, on top of every price on this page.

05 / Coverage
Where they are worth buying
The 40 cheapest of the 157 markets they reach. A provider can be excellent value in one country and poor in the next, because coverage is not a quality.
No market here matches that search.
06 / Buying and support
What the purchase is actually like
Price is half a review. This is the other half, taken from what their catalogue publishes rather than from their marketing. A share of nothing means they do not publish it.

07 / Accuracy
Does their listed price survive to checkout?
We measure this ourselves rather than taking their word for it.
Measured from our own outbound clicks, not from anything they told us.
Nobody has clicked through to this provider often enough for us to have measured it. We publish the figure when there is one, not a default.
A score below 100% is not automatically dishonesty. Currency conversion, regional pricing and stale caches all cause it. It does mean you should read the total before paying.
Links to this provider may earn us a commission at no extra cost to you. It has no bearing on their position in any ranking, and no payout figure is available to the code that ranks plans.
08 / Readers
