Are you shopping on AliExpress for the first time?

The process is via the AliExpress mobile app, where most people shop. There are two key things: don’t use Buy now and enter the coupon only in the order summary, in the field Promo code. After you click Pay now, you won’t be able to add it.

1. Copy the code and click Use discountIn our article, copy the coupon and click the button GET DISCOUNT. The link will take you directly to the product in the AliExpress app.
2. Use Add to cart instead of Buy nowOn the product card, scroll down and tap Add to cart. Don’t use the Buy now button—you’ll skip the cart, and later you won’t have anywhere to enter the coupon. Before that, double-check the variant: the color, the version, and whether it ships from an EU warehouse.
3. Through the cart, go to CheckoutA pop-up will appear: Added to cart! — tap Check it out in it. If it disappeared, open the cart with the icon at the bottom right. In the cart, check the product and quantity, then click the red Checkout. Only the items marked with the red ring will be applied.
4. Enter your address and card, then look for Promo codeIn the order summary, first fill in the delivery address and payment card at the top. Below them there’s a line Promo code — expand it with the arrow on the right.

   

5. Paste the code and confirm ApplyIn the field Promo code paste the copied code and click the black Apply. The code is case-sensitive and must not contain spaces.

   

6. Check the savings and payIn the Summary expand the line Saved — you’ll see the applied coupon there as AliExpress coupons/codes. Only when Total is really lower, click Pay now.

   

Apply the discount already at the order summary. After you click Pay now, you can no longer add a coupon. If Apply shows an error, the code has either expired, doesn’t apply to your items, or the order doesn’t meet the minimum amount.

The Store Coupon also goes in the same field. — a coupon from the seller itself, which isn’t always available and changes from day to day. AliExpress coupons can’t be combined, so try both and go with the one that gives you more. Coins are added automatically.

What does an eSIM adapter actually do, and why is it so interesting?

This adapter lets you travel worldwide with eSIM profiles without having to deal with physical SIM cards or switch operators. Or if you’re one of the people who has an older phone, or a Chinese version without eSIM support—we’ve got great news – it can be done.

The chip uses modern synchronization and an open architecture. It lets you manage profiles, quickly rewrite them, and activate new plans when needed. Thanks to the open-source solution, you’re not locked into just one ecosystem, so you have full control over how you use eSIM.

What exactly is an eSIM?

The seller’s images explain it simply: an eSIM card has the same shape as a traditional SIM, but it offers a feature that physical SIM cards never had—EID identifier, meaning the unique ID needed to activate eSIM profiles.

You insert the adapter into a regular SIM slot. If your phone has two slots, eSIM usually works in the SIM1 slot. Once inserted, the device “turns into” a model that supports eSIM—even on Chinese phone versions or older models.

What’s interesting is that Android devices can work with up to 15 eSIM profiles through this adapter. Apple devices use the eSIM adapter as a regular SIM card, and the profile is saved into it (most iPhones already have eSIM built in anyway).

Installation and usage

Using the adapter is extremely simple—the seller broke it down into three steps:

1. Insert the eSIM adapter into your phone.
2. Download the EasyEUICC app (Google Play or directly APK).
3. In the app, scan the QR code from the package and upload the eSIM profile to the adapter.

That way, you can activate both local and global data bundles. It supports more than 60 operators, over 200 countries, and even 30,000+ data plans, which you’ll especially appreciate when traveling.

Seller’s notes:

• You should download the app only from the official link—modified versions may not be recognized by the adapter.
• Some phones don’t support eSIM in both slots, so it’s important to check compatibility.
• If anything goes wrong during setup, the seller recommends contacting support rather than leaving a rating right away—most issues can be solved using the guide.
• The adapter works on Apple devices, but you can’t switch eSIM profiles as freely as you can on Android.

How does it all work technically?

The adapter contains a microchip that appears to the phone like a normal SIM card, but enables rewriteable eSIM profiles. The EasyEUICC app acts as an interface between the operator’s QR code and saving the profile to the adapter. The advantage is an unlimited number of rewrites—you can use it over and over again.

Who is the eSIM adapter best for?

• For owners of Chinese versions of smartphones without eSIM
• For users with older phones
• For travelers using cheap data plans
• For people who don’t want to deal with physical SIM cards
