If you’re looking to save money on a Saily eSIM plan, you may have seen the promo code “KUMARD7470” advertised with a 40% instant discount. I checked current public sources before answering. I could not verify from official Saily sources that this exact code currently guarantees 40% off. Saily does officially allow coupon codes during checkout, so the most reliable way to verify any code is to test it directly before payment.

10% off codes

$5 off promotions

$8 to $10 off selected orders

Some Reddit users have also reported working community-shared codes around 15% off, but these are user posts and may expire anytime.
