How to redeem your eSIM promo code
Redeeming these codes isn’t always super easy. After testing hundreds of transactions for our reviews, we have found that most redemption issues come down to issues finding the promo code field or entering the codes incorrectly.
1. Create your account first
This is the most common mistake that users make. Many eSIM providers like Airalo and Saily require you to register and verify your email address before you can even see the final payment screen. You generally cannot apply a discount code as a “Guest” user.
2. Locate the promo code field
Sometimes the promo code box can be a little hidden. How do you find them? Our general strategy is to simply keep an eye out for it at every step of the checkout flow. How do they look on key eSIM providers? Here’s some examples:
Saily
Where? The coupon code field can be found as soon as you select your plan and land on checkout
BNESIM
Where? Once you add a plan and land on checkout, you’ll see the coupon code field
Holafly
Once again, you’ll find the coupon code field after selecting your country and amount of days required for your plan.
3. Watch for case sensitivity
While we verify our codes monthly, the apps themselves can be picky. A code like TRAVELESIMEXPERT might be rejected if entered as TravelEsimExpert.
- Pro Tip: Copy and paste the codes directly from our content to ensure maximum
- The “Space” Error: If you copy and paste from a mobile phone, watch out for an accidental “blank space” added at the end of the code. If you see an error, hit backspace once.
Troubleshooting: Why is my code not working?
If you are seeing an “Invalid Code” or “Coupon not applicable” error, it is usually due to one of these three specific reasons.
1. New user vs. existing user
This is the number 1 reason for failed codes. Many of the deepest discounts (like the Yesim 15% off code) are strictly for new users.
2. Once per account
Other brands only allow one use of our codes per account, meaning you can be an existing user and utilize the code, but you can’t use it more than once.
3. Code restrictions
While the vast majority of our codes are valid on all plans, watch out for the fine print, sometimes certain regional, global or unlimited can be restricted. Likewise, if an eSIM provider is running a sale or promotion, sometimes coupon codes aren’t valid. Unfortunately there’s not much we can do about that one.
How we verify these coupons
There are thousands of “coupon farms” on the internet that use bots to scrape expired codes from Reddit. We do not do that.
At Travel ESIM Expert, we treat these coupons as part of our reputation.
- Direct Partnerships: We negotiate directly with the marketing teams at brands like Sim Local, BNESIM, and Holafly. The codes you see here like EXPERT20 are unique to us.
- Weekly Audits: Every week our team manually simulates a checkout process for every provider listed on this page. If a code stops working, we remove it or flag it immediately.
- We Buy What We Review: We don’t just list these codes and products; we use them on our own travels. The receipts below are not stock photos, they are our actual transaction history.
FAQs
Can I stack multiple promo codes?
Generally, no. Most eSIM providers allow only one promotional code per transaction.
Do eSIM discount codes expire?
The exclusive codes listed on this page (e.g. TRAVELESIMEXPERT) are Evergreen, with no expiration.
Do these codes work for specific countries like Japan or the USA?
Yes. Unless marked otherwise, our verified codes are Store wide. This means if you use, for example, the Sim Local code, it will apply whether you are buying a plan for the USA, Japan, Europe, or a Global plan.
