Our quick verdict

Simbye is worth considering if you want a simple travel eSIM that works reliably and gives you more flexibility than a basic fixed data plan.

We’ve tested Simbye in 8 Countries countries so far. The service was easy to install, mobile data worked straight away, hotspot worked and we didn’t experience any signal dropouts during testing.

Its biggest standout feature is the ability to customize your own eSIM. You can combine up to 10 countries, choose between 5 GB and 50 GB of data and select a validity period between 30 and 365 days.

That’s genuinely useful if your trip doesn’t fit neatly into a standard country or regional plan.

That said, Simbye hasn’t ranked as a top speed provider in our tests so far. It worked reliably, but it was not one of the fastest eSIMs in any of the countries where we tested it.

Customer support is also something we want to test further. There is no chat or customer support option directly inside the Simbye app, so you need to go to the website to get in touch. We tried the live chat on the website and didn’t get a reply, so support isn’t looking like Simbye’s strongest area at the moment.

Simbye is a reliable and flexible eSIM provider, but not a speed-first option. It’s worth considering if you like the custom eSIM builder, want top ups and need something that works. If maximum speed or fast customer support matters most to you, compare it with other providers before buying.

How to use our Simbye discount code

Using the Simbye discount code is simple. You can redeem it inside the app or on the website.

Here’s how to use our Simbye discount code step by step:

Step 1: Choose your destination

Open the Simbye app and search for your destination.

You can search for:

  • A country
  • A region
  • A global plan
  • A custom eSIM

One thing to note is that the worldwide plan appears in the regional section.

Simbye also gives you the option to personalize your own eSIM. This is one of its strongest features because you can mix and match countries, data amount and validity in one single plan.

Step 2: Pick the plan that suits your trip

Once you have selected your destination or custom plan, choose how much data you need and how long you need the eSIM to last.

Our experience testing Simbye

We tested Simbye recently across 8 Countries: Hong Kong, Korea, Macau, Malaysia, Portugal, Singapore, Spain, Thailand.

Our tests took place across April, May and June 2026 using:

  • iPhone 17 Pro Max
  • iPhone 15 Pro
  • iPhone 13 Pro Max

The installation process was smooth. We didn’t need to manually change APN settings, mobile data started working straight away and hotspot worked during our testing.

We also had no signal dropouts. That matters because speed is only one part of the eSIM experience. A very fast eSIM that constantly disconnects is still annoying to use. With Simbye, the speeds weren’t always impressive, but the service itself was stable.

Here’s how Simbye performed in our testing compared with other eSIM providers:

Overall, Simbye hasn’t ranked as a top speed provider in our tests so far.

That doesn’t mean it’s unusable. In real terms, the connection worked, maps loaded, browsing worked and hotspot worked. However, if you’re trying to find the fastest possible eSIM for your trip, Simbye wouldn’t be our first choice based on our current results.

What we liked about Simbye

The biggest thing we liked about Simbye wasn’t speed. It was flexibility.

1. You can customize your own eSIM

This is the main feature that stands out to us.

Simbye lets you create a custom eSIM where you can combine up to 10 countries, choose between 5 GB and 50 GB of data and select a validity period between 30 and 365 days.

That’s very useful for travelers who don’t fit neatly into a standard country or regional plan.

For example, this could work well if:

  • You’re visiting several countries that aren’t grouped together in one regional plan
  • You want one eSIM for a longer trip
  • You need more control over your data amount
  • You want a longer validity period than standard short travel plans
  • You don’t want to buy separate eSIMs for each destination

We haven’t seen many providers offer this level of plan customization, so this is probably Simbye’s most distinctive feature.

2. Some destinations include phone number options

This is another interesting thing about Simbye.

Most travel eSIM providers focus only on mobile data. Simbye also offers phone number products in selected destinations, including options for places like the USA, UK, Thailand and Europe.

Some plans may include calls, SMS or a real phone number, depending on the destination and product.

That could be interesting if you need more than just mobile data.

3. Europe plans with calls and SMS are more distinctive

Simbye’s Europe product is more appealing than a standard data-only travel eSIM because some plans include a real French number, EU calls and SMS, and global minutes on selected options.

This makes it stand out more in Europe than in destinations where it’s simply offering standard data packages.

4. Simbye says users can earn 5% cashback

Simbye also promotes 5% cashback on eSIM purchases, credited to the user’s wallet for future orders.

We like this idea because it gives returning customers a reason to keep using the service, especially if they travel regularly.

Is Simbye worth trying?

Our exclusive Simbye discount code TEE15 gives you 15% off All plans. It works for All users, with no expiry date currently.

After testing Simbye in 8 Countries, our view is generally positive.

Simbye is not the fastest eSIM provider we’ve tested. It ranked in the middle or lower part of the table in our current speed tests, so we wouldn’t recommend it as the best choice if speed is your main priority.

Customer support also needs more testing. There is no in-app support and when we tried the website live chat, we didn’t receive a reply during our test.

However, Simbye has been reliable. Installation was easy, mobile data worked straight away, hotspot worked and we had no connection issues during testing.

The custom eSIM builder is the biggest reason Simbye stands out. Being able to combine up to 10 countries, choose between 5 GB and 50 GB of data and select a validity period from 30 to 365 days is useful, especially for travelers with more complex trips.

So, would we recommend Simbye?

Yes, but with context.

Simbye is a good option if you want a reliable and flexible travel eSIM that works properly, supports top-ups and gives you more control over your plan. If your priority is maximum speed or fast customer support, compare it with other providers first.

What is the Simbye discount code?

The current Simbye discount code is TEE15. It gives you 15% off on All plans.

Does the Simbye discount code work for existing customers?

Yes. Our Simbye discount code works for both new and returning customers. That means you can use it whether you are placing your first order or buying another Simbye eSIM for a future trip.

Is Simbye good?

Based on our testing so far, Simbye is reliable and easy to use, but not one of the fastest eSIM providers we’ve tested.

We’ve personally tested Simbye in 8 Countries: Hong Kong, Korea, Macau, Malaysia, Portugal, Singapore, Spain, Thailand. Setup was easy, mobile data worked straight away, hotspot worked and we didn’t experience signal dropouts.

The most interesting feature is the custom eSIM builder, which lets you combine up to 10 countries, choose 5 GB to 50 GB of data and select 30 to 365 days of validity.

Do you have a full Simbye review?

Not yet. However, we’ve already tested Simbye in 8 Countries and we’re continuing to collect more data.

So far, our experience has been reliable. It’s worked properly everywhere we tested it, but it hasn’t been one of the fastest providers in our speed rankings.
We also need to test customer support further before giving a complete review.

Can you customize your own Simbye eSIM?

Yes. This is one of Simbye’s standout features.

Simbye lets you customize your own eSIM by combining up to 10 countries, choosing between 5 GB and 50 GB of data and selecting a validity period between 30 and 365 days.

This is useful if your trip doesn’t fit neatly into a standard country or regional plan.

Does Simbye offer unlimited data?

From what we’ve seen so far, Simbye doesn’t appear to focus on unlimited data plans. It mainly offers fixed data plans, customizable eSIMs, country plans, regional plans and global plans.

Some plans include larger data allowances, so it may still work for heavier users, but if you specifically need unlimited data, compare plans carefully before buying.

How we test eSIMs

Speed Testing

We run 3 consecutive speed tests using Speedtest by Ookla in the same physical location with at least 3 out of 4 signal bars. If all 3 results fall within roughly a 15% download speed range, we record the highest result. If results vary more than this, we rerun the test to avoid random spikes or drops. This reflects realistic peak performance under stable conditions.

Stability Check

We use the eSIM normally over at least 2 to 3 days and note:

  • Any full signal dropouts
  • Whether reconnections happen automatically
  • Whether any manual intervention is needed

If no issues occur, we state that explicitly.

Real-Life Usage Tests

We test every eSIM with common everyday tasks, including:

  • General web browsing
  • Google Maps loading and navigation
  • WhatsApp messaging and media sending
  • Uploading photos to cloud storage
  • YouTube streaming (HD playback)
  • Hotspot usage where supported, connecting a 2nd device

These checks confirm the connection is usable in real travel scenarios, not just fast in speed tests.

Customer Support Testing

We run quarterly support reviews across all providers using the same questions for each provider. We record and rate:

  • Time to 1st human response
  • Support channel used (live chat, email, WhatsApp)
  • Whether the response is human or automated
  • Whether the issue is resolved in the 1st interaction
  • Overall clarity and usefulness of the reply

Support results shown in reviews reflect the most recent quarterly test.

Devices

We test on:

iPhone 13 Pro Max iPhone 15 Pro Max iPhone 17 Pro Max iPad Pro M2
