Description

Simbye is an eSIM solution designed for travelers who want a simple and affordable connection abroad, without a physical SIM card or commitment. The website and app allow you to purchase prepaid data plans covering more than 190 countries within minutes, from small volumes for city trips to larger options for long stays, often with 4G or 5G. The eSIMs are rechargeable, contract-free, and without hidden fees, sometimes with a free trial offer and a cashback program in the app. Simbye is particularly suitable for leisure travelers, frequent business travelers, and digital nomads seeking a reliable, flexible, and fully digital connection.

How it works

Go to the Simbye website or app, select your destination (country or region), then compare the available data plans.

Create a Simbye account or log in, then check that your phone is eSIM compatible before continuing the purchase.

Confirm the chosen plan and pay online with one of the provided payment methods, ensuring your email address is correct.

After payment, you receive a confirmation email with the eSIM QR code or an installation link, also accessible from your client area.

On your smartphone, open mobile network settings, choose Add mobile plan, then scan the QR code or follow the guided installation.

Upon arrival, select the Simbye line for mobile data, enable roaming, and disable data on your main SIM if needed.

Use the app or Simbye client area to track your data usage and, if needed, recharge your eSIM before the plan ends.

⚠️ If it fails

✅ Check your phone's eSIM compatibility, your internet connection quality at installation time, and carefully follow the steps. If errors persist, quickly contact Simbye support via chat or WhatsApp.

✅ Make sure the Simbye line is selected for mobile data, roaming is enabled, and restart your phone. If the problem continues, try switching between 5G/4G and contact support with screenshots.

✅ Check phone and Simbye app settings for which apps consume the most data, limit HD streaming, automatic updates, and enable data saver mode if available.

✅ Log back into your Simbye account to retrieve the QR code or installation link, or request a resend by email from support if you cannot find the original message.

FAQ

For a short stay in Europe, a local or regional Simbye plan of 5 to 10 GB is generally sufficient for browsing, social networks, and light streaming. Check the validity duration and the presence of 4G/5G in the target country before purchase.

On most eSIM compatible smartphones, the hotspot works with a Simbye eSIM, but it also depends on the local partner operator. However, avoid very heavy usage (mass downloads, 4K streaming) to not exhaust your plan too quickly.

Simbye plans are mainly data-only offers, without local number or classic SMS/calls included. To call or send messages, use apps like WhatsApp, Telegram, or FaceTime Audio that work over data.

Simbye works with most recent eSIM compatible smartphones, such as recent iPhones, many Samsung Galaxy models, Google Pixel, and other Androids. Check your brand's compatibility list and ensure eSIM functionality is enabled by your operator.

Yes, most eSIM phones allow simultaneous use of a physical SIM and a Simbye eSIM. You can keep your main SIM for calls/SMS and reserve Simbye for mobile internet roaming.

Log in to your account on the Simbye site or app, open the concerned eSIM, then choose a recharge option available for the same destination or region. The new data volume is usually added within moments after payment.

Refund requests are handled on a case-by-case basis and depend notably on whether the eSIM was activated or not. In case of technical issues, gather screenshots of network settings and promptly contact Simbye support to explain the situation.

Yes, it is possible to buy and install the Simbye eSIM before traveling, then activate it only upon arrival in the country. Just ensure that the plan validity period starts at activation on the network and not at the purchase date.
