eSIM Promo Codes: Current Discounts for Travel eSIMs

If you're planning an international trip, a travel eSIM can be a convenient way to get mobile data without relying on expensive roaming. And if you can save a little more with a working promo code, there's even less reason to pay full price.

I’ve put together the eSIM promo codes and coupon codes currently available through StackPulse, focusing on three providers: MyEsimGlobal, eSIM.dog and Saily.

Before using any code, check the final price at checkout because provider promotions, eligibility and plan conditions can change.

eSIM Promo Codes at a Glance

These are the partner codes available through StackPulse. Check the final price and eligibility before completing your purchase.

1. MyEsimGlobal Promo Code — 10% Off

Code: BEINGOPTIMIST10

If you're looking for a travel eSIM with a wide selection of destinations, MyEsimGlobal is one provider worth comparing.

MyEsimGlobal currently lists plans for 190+ destinations, including local, regional and global options. Its website also shows plans starting from €0.99 for selected destinations.

How to use the MyEsimGlobal code

1. Visit MyEsimGlobal.
2. Select your destination.
3. Choose your eSIM plan.
4. Enter BEINGOPTIMIST10 where the promo code is accepted.
5. Confirm that the discount has been applied.
6. Complete your purchase.

If you want to understand the service before buying, see our MyEsimGlobal review on BeingOptimist.

2. eSIM.dog Promo Code — 5% Off

Code: BEINGOPTIMIST5

eSIM.dog is another option worth checking if you're comparing travel eSIM providers.

It offers destination-specific and regional connectivity options, while its WorldPass is designed for travellers who want broader international coverage.

If you're a frequent traveller, WorldPass is particularly worth investigating rather than automatically choosing a separate eSIM for every trip.

How to use the eSIM.dog code

1. Open eSIM.dog.
2. Select the WorldPass or another suitable plan.
3. Continue to checkout.
4. Enter BEINGOPTIMIST5 if a promo-code field is available.
5. Check the final price.
6. Complete the purchase.

3. Saily Promo Code — 10% Off

Code: BEINGOPTIMIST10

Saily is another strong option for travellers who want a simple app-based eSIM.

Saily currently lists plans across 209 destinations, including country and regional options.

One advantage is that Saily allows you to use one eSIM and add plans for supported destinations rather than necessarily installing a new eSIM for every trip.

How to use the Saily code

1. Choose your destination.
2. Select a Saily plan.
3. Continue to checkout.
4. Select “Got a coupon?”
5. Enter BEINGOPTIMIST10.
6. Click Apply and check the discounted price.

Saily's own help documentation confirms that promo codes can be entered during checkout through the “Got a coupon?” option.

Which eSIM Promo Code Should You Use?

There isn't one provider that's automatically best for every traveller.

Your destination and data requirements should come first.

Choose MyEsimGlobal if:

• You want a large selection of country plans.
• You need regional or global coverage.
• You want to compare different data allowances.
• The MyEsimGlobal plan is competitively priced for your destination.

Consider eSIM.dog if:

• You're interested in WorldPass.
• You travel between multiple countries.
• You want to compare another international eSIM option.
• Its destination coverage and plan conditions suit your trip.

Consider Saily if:

• You prefer managing your eSIM through an app.
• You're travelling across multiple supported destinations.
• You value additional security features.
• Its price is competitive for your destination.

Saily currently advertises 200+ destinations, regional/global plans and built-in security features.

Don't Choose an eSIM Based Only on the Discount

This is probably the most important advice I'd give a traveller.

A 10% discount doesn't automatically make a plan better.

Before entering a promo code, compare:

• Total data allowance
• Number of valid days
• Countries covered
• Local network partners
• High-speed data limits
• Hotspot support
• Activation requirements
• Final price after the discount

For example, MyEsimGlobal currently offers a wide range of local and regional plans, while Saily has more than 200 destinations. The actual value depends on the plan you select.

So my approach would be:

Choose the right provider → choose the right plan → apply the promo code → check the final price.

Not:

Choose the biggest discount → buy whatever plan is offered.

Final Take

If you're buying a travel eSIM, use the discount as the final step, not the deciding factor.

Start by finding the plan that actually fits your destination and usage. Then apply the relevant StackPulse code:

• MyEsimGlobal: BEINGOPTIMIST10 — 10% off
• eSIM.dog: BEINGOPTIMIST5 — 5% off
• Saily: BEINGOPTIMIST10 — 10% off

Promo availability and eligibility can change, so always confirm that the discount is reflected in the checkout total before paying.
