If you’re planning a trip and want cheaper mobile data, Saily is a convenient eSIM option for travelers. Many people search for working promo codes before checkout. One code being promoted is “KUMARD7470.” However, I could not verify from official public Saily sources that this specific code is 100% working or guarantees 40% off right now. The safest claim is that it is a code worth trying at checkout, where Saily officially supports coupon entry.

Is 40% Off Confirmed?
I did not find an official Saily source confirming KUMARD7470 = 40% off all plans. Saily’s own coupon pages mention discounts but do not publicly list this exact code/value combination.
Recent third-party sources and community posts more commonly mention smaller offers such as 10%–15% off or fixed dollar credits, though these may also change.

Final Verdict
The Saily 100% Working Coupon Code “KUMARD7470” claim could not be independently verified from official sources today. It may still work for some users or limited campaigns, so it’s worth testing at checkout. But I can’t confirm a guaranteed 40% discount at this time.
