## Where to enter it

At checkout, before you pay. There is a field for a code on the payment step. Enter it, apply it, and check the total changes before you complete the order.

## Enter it exactly

Codes are usually not case sensitive, but they are sensitive to stray spaces, which is easy to pick up when copying from a message. Paste it and then check for a space at either end.

## After you have paid

A code cannot be applied to a completed order. If you forgot, contact us before you use the eSIM and we will see what we can do rather than leaving you out of pocket.

## Referral codes

A referral code is entered the same way. The person who referred you receives their reward once your order completes. See "My referral credit has not arrived".

## If it is rejected

See "My promo code will not apply", which covers the usual reasons.
