Yesim promo code — frequently asked questions
Yes, the MYBESTSIM20 code is currently active on yesim.app and knocks 20% off every eSIM plan the provider sells.It was tested and confirmed live on October 14, 2026, directly at yesim checkout: a 15-day Global plan listed at $45.00 dropped to $36.00 once the code was applied.It works the same way for first-time buyers and returning customers alike.
At yesim.app checkout, look for the field labeled 'promo or referral code' just before you confirm your order.Type in MYBESTSIM20 and hit the 'Redeem' button, and the discounted total updates instantly in your order summary.You don't need to log in or create an account to redeem the code — that step is optional on yesim.
MYBESTSIM20 takes 20% off any yesim eSIM plan, no matter which destination you're buying for.For example, a 15-day Global plan priced at $45.00 drops to $36.00 after the code is applied — a $9.00 saving.The discount is calculated automatically on the listed price at checkout.
As of now, MYBESTSIM20 has no known expiration date.It runs as a standing, ongoing code on yesim.app rather than a short-term promotional offer.It's still worth double-checking the discounted total in your order summary at checkout, since that's the clearest confirmation the code went through.
Yes, MYBESTSIM20 can be redeemed on every order placed at yesim.app, with no known limit on how many times it can be used.It isn't a one-time, first-purchase-only code, since it applies equally to new and existing yesim customers.You do need to re-enter it each time, though, as it isn't automatically saved between purchases.
If the discount isn't showing up, the most common culprit is a typo in yesim checkout's 'promo or referral code' field — the code needs to be entered exactly as MYBESTSIM20, with no spaces.Make sure to hit 'Redeem' and let the order summary refresh before finalizing payment.If the price still hasn't changed, refreshing the checkout page or trying a different browser usually clears it up.
MYBESTSIM20 is meant to be used on its own — yesim's checkout generally only accepts one promo or referral code per order.Some plans already listed at a discounted price as part of a separate offer may not accept an additional code on top.If you're unsure about a specific plan, the safest check is to confirm the 20% discount shows up in the order summary before you pay.
MYBESTSIM20 applies across yesim's entire eSIM lineup, with no restriction by destination or plan length.Whether you're buying a single-country plan, a regional bundle, or a global plan, the 20% discount applies to whatever price is shown at checkout.There's no special plan category you need to pick for the code to be accepted.
