Worth knowing first

What TailSim charges before the discount

A percentage off a dear plan can still be dearer than full price somewhere sensible. These are the figures the code applies to.

Using it

Using a promo code at TailSim

Three steps, and the third is the one people skip.

Copy the code above

Use the copy button rather than selecting it by hand. A trailing space pasted from a web page is the commonest reason a perfectly good code is refused.

Pick your plan first

Settle the destination, the allowance and the validity before thinking about the discount. A code cannot rescue a plan that is the wrong shape for the trip.

Check the total actually moved

Some checkouts accept a code, show a confirmation and change nothing, because the plan is excluded. Read the total before and after, not the success message.

If it fails

Why a code gets refused

Nearly always one of these four, and only the last is the provider's doing.

The plan is excluded Regional and unlimited plans are the usual exclusions and the checkout rarely says so. Try the code against a standard single-country plan to tell an exclusion from a dead code.

It is new customer only Tied to the account rather than the device. If you have bought from that provider before, on any handset, the code is usually dead for you specifically.

A sale is already applied Most codes do not stack. During a seasonal sale the discounted price often beats the code anyway, so compare the two totals rather than assuming the code wins.

It has been withdrawn Providers retire codes without notice and without publishing an end date. That is exactly why every code here carries a check date instead of a promise.

We do not test codes by placing orders, because automated coupon testing means submitting fake purchases against a merchant who never agreed to it. We check by hand and publish the date. If this one has stopped working, tell us and it comes off the page.

Questions

TailSim codes, answered

Short answers. The longer ones live on the methodology page.

Is the TailSim code AFFINCO still working?

It was checked by hand at their own checkout on 8 October 2026. That is the date on the card, not an estimate. Codes are withdrawn without notice, so if it fails at the till, the date tells you how stale our check is.

How much does the TailSim code save?

10% off, applied to their published price at their checkout. It does not stack with a sale they are already running, and it is not reflected in any price on this site.

Why do you not test codes automatically?

Automated coupon testing means submitting fake purchases against a merchant who never agreed to it. We check by hand instead, which is slower and honest, and we publish the date we did it.

Does using the code cost me anything?

No. We may earn a commission if you buy after following a link here, at no extra cost to you. The discount is the same whether you use our link or not, and commission carries no weight in any ranking.
