ESIMADVICE LISTING Verified 721 live plans · 158 countries

Simbye review: our honest take

Simbye is a travel eSIM brand that goes beyond fixed data packs: its app includes a custom eSIM builder where you choose your own data size, validity and multi-country coverage, and its data eSIMs are rechargeable so the same install works across repeat trips. It also sells optional real virtual phone numbers (French, UK, US and Thai) for calls, SMS and verification codes. On eSIMAdvice we track 721 live Simbye plans across 158 countries starting at $2.99, with our exclusive ESM15 code (15% off) already applied to displayed prices.

Match the plan to your trip length and expected data usage before choosing Simbye.

Check whether hotspot, 5G, roaming partners, and fair-use limits fit your phone and destination.

Confirm final taxes, activation timing, refund terms, and supported networks on the provider checkout page.

👍 What we like

✓Installed eSIMs stay valid for months before the trip and only start counting when you connect at the destination — no manual activation needed

✓App-exclusive custom eSIM builder lets you pick your own data amount, validity period and multi-country coverage

✓Data eSIMs are rechargeable: top up the same profile on later trips instead of reinstalling

✓Optional real virtual phone numbers (French, UK, US, Thai) for calls, SMS and verification codes

✓Very broad payment support, including PayPal, Klarna, iDEAL, Apple/Google Pay and USDC

✓Hotspot/tethering is explicitly allowed on data plans

👎 Worth noting

–Unlimited plans carry a daily high-speed fair-use cap, after which speeds are reduced until the next 24-hour cycle

–No pay-as-you-go or no-expiry options — every plan runs on a fixed validity window

–Once the eSIM is installed and data is used, refunds are only granted for documented network failures

–The custom plan builder and the 5% purchase discount are app-only, so web-only buyers miss those features

How Simbye works

1Pick a plan

Choose a Simbye plan above by destination, data, and validity. Prices already include any eSIMAdvice coupon.

2Install over Wi-Fi

Buy through the provider, then scan the QR code or use their app to add the eSIM to your phone before you travel.

3Connect on arrival

Turn the eSIM line on for data when you land — your main SIM stays active for calls and texts.

Google PixelPixel 3 and newer — Pixel 6–9 series fully supported (carrier-unlocked)

About Simbye

You buy on simbye.com and the eSIM arrives by email within minutes as a QR code; scan it over WiFi and installation typically completes in under a minute, with a manual SM-DP+ address option as a fallback if scanning fails. A key Simbye trait is the generous pre-trip window: the installed eSIM stays valid for up to 180 days before first use, and the plan only starts counting once you arrive, enable data roaming and connect to a local network — no manual activation step. If you use the Simbye app instead of the website, purchases get a 5% discount and you can top up the same eSIM later without installing a new profile. Payment options are unusually broad, including PayPal, Klarna, iDEAL, Apple/Google Pay and even USDC.

Simbye — quick answers

What is the cheapest Simbye eSIM plan?

The cheapest live Simbye plan listed on eSIMAdvice is $2.99. In total we track 721 live Simbye plans across 158 countries, including unlimited-data options, so most destinations have several price points to compare.

Is there a working Simbye coupon code?

Yes. eSIMAdvice has an exclusive Simbye code, ESM15, which takes 15% off. The prices displayed on our Simbye listings already include this discount, so what you see is the coupon-adjusted price.

When does a Simbye eSIM start its validity period?

Not at installation. You can install the QR code up to 180 days before your trip and the plan only begins when you arrive in the destination country, enable data roaming and connect to a local network. Activation is automatic — there is no button to press on arrival.

What is Simbye's custom eSIM builder?

Inside the Simbye app you can build your own plan instead of picking a preset: choose a data amount from 5GB to 50GB, a validity period from 30 to 365 days, and coverage for up to 10 countries on a single eSIM. This builder is app-exclusive and is not available on the website.

How do Simbye's unlimited plans handle heavy use?

Simbye's unlimited plans have a published fair-use policy of 2GB of high-speed data per day; beyond that, speeds are reduced until the next 24-hour cycle resets the allowance. Hotspot sharing is allowed, but tethered usage counts toward the same allowance.
