How the Voice Plan Works
This eSIM provides mobile data alongside a real phone number capable of voice calls and SMS—not just data connectivity. The number assigned is French (+33), which means callers dial a French prefix to reach you, regardless of where you're travelling.
Outgoing calls and SMS are unlimited, but only while you are physically located within geographic Europe. This includes all of the European continent, not just EU or EEA countries. Step outside Europe—say, during a layover in Istanbul's Asian terminal—and outgoing service pauses until you return to European soil.
Incoming calls and SMS are free and arrive anywhere in the world. This is the feature that matters for verification codes: your bank in London, your airline's booking system, or your apartment host can all send texts or make callbacks to your French number, and you receive them whether you're in Prague, Marrakech, or Tokyo. Incoming communication is not deducted from any allowance.
All plans include 30 days of validity. The line cannot be refilled or extended—once data runs out or validity ends, the number stops working permanently.
Receiving SMS Verification Abroad
Is This Plan Right for You?
The Voice plan fits you well if: You need to receive SMS verification codes from banks, airlines, or apps that won't send to your home number abroad. You expect callbacks from hotels, car rentals, or local services. You want to make voice calls across Europe without watching a meter. You're coordinating with others who need a number to dial, not just a messaging app handle.
A data-only plan may suit you better if: You communicate primarily through WhatsApp, iMessage, or other internet-based apps and nobody needs to call or text your actual number. You don't rely on SMS-based two-factor authentication while travelling. You want maximum data for the lowest price and have no voice requirements. If that describes your trip, consider the Czech Republic Unlimited instead, which focuses purely on connectivity without the phone-number features.
Still weighing options? The Czech Republic compares all available plans for your destination, including standard data eSIMs with longer validity periods.
Traveler Tips
- Update your banking app's registered phone number to your new French (+33) number before departure—some banks require the change while you still have home network access.
- Save your Voice eSIM number in your own contacts so you can easily share it when hotels or services ask for a callback number.
- Test your eSIM immediately after activation by sending yourself a text from another device, confirming SMS delivery works before you need it urgently.
- Remember outgoing calls and SMS only work within geographic Europe—if you have a layover outside Europe, wait until you return to European coverage to make calls.
- Keep your home SIM installed but disabled; if you need to switch back temporarily for a specific app tied to that number, you can toggle between lines.
- Download offline maps and translation apps over Wi-Fi before exploring—your data allowance lasts longer when you're not streaming content constantly.
Before you buy
- Your number is French (+33) and it is not permanent — it changes roughly every 30 days.
- Verification codes arrive fine during your trip. But don't set this as your permanent number for two-factor authentication or WhatsApp: when it changes, you can lose access to that account.
- There is no top-up. When the plan ends the line closes — a new plan means a new eSIM to install and a new number.

Frequently Asked Questions (FAQs)
The Voice eSIM assigns a French (+33) number regardless of your destination country. This allows the same number type to work across all European coverage areas. Anyone calling you simply dials the French number, and the call reaches you in Czech Republic or anywhere else. Share this number with contacts, banks, or services that need to reach you.
Yes. Incoming calls and SMS are free and work anywhere in the world—not just in Europe. If you fly from Prague to New York, verification codes from your bank or booking apps still arrive on your French number. Only outgoing calls and SMS are restricted to geographic Europe.
The line closes permanently. Voice eSIMs cannot be refilled, topped up, or extended. Once your data allowance is exhausted or validity expires—whichever comes first—the number stops working. If you need continued service, you would purchase a new eSIM with a new number.
Outgoing calls and SMS are unlimited throughout geographic Europe—the physical continent, not a political or economic zone. This includes non-EU countries like Switzerland, Norway, and the UK. If you travel outside Europe (such as to Turkey's Asian side or North Africa), outgoing service pauses until you return to European territory.
No. The Voice eSIM line cannot be refilled or extended under any circumstances. Plan your data needs for your full trip duration. If your travels extend beyond 30 days, you would need to purchase a new eSIM, which would come with a different phone number.
The eSIM receives SMS sent to your French number from anywhere in the world, including from banks and financial institutions. However, some banks restrict SMS delivery to numbers registered in specific countries. Contact your bank before travelling to confirm they can send verification codes to a French mobile number and update your registered number if needed.
Travel Blog
The Czech Republic Voice eSIM combines mobile data with a working phone number, delivering something a data-only plan cannot: the ability to make and receive calls and SMS. Outgoing calls and texts are unlimited while you remain anywhere in geographic Europe—not limited to EU member states, but the entire European continent. Incoming calls and SMS are free and work anywhere in the world, meaning your verification codes from banks, airline apps, and booking platforms arrive whether you're exploring Český Krumlov or catching a connecting flight through Dubai.
This plan fits travellers who need genuine two-way communication. If your bank sends SMS codes you must receive to authorise transactions, if rental agencies call to confirm pickup details, or if colleagues need to reach you by phone, the Voice plan solves problems that data-only connectivity cannot. However, if your travel revolves around maps, social media, and messaging apps that work over data, and nobody needs to dial or text your number, a standard data plan costs less and may suit you better.
Every Voice plan runs for 30 days from activation. The line cannot be refilled or topped up—when your data, minutes, or SMS allowance runs out, or when validity expires, the service ends. The number assigned is French (+33), not a local Czech number, so anyone calling you dials the French prefix. Plan accordingly: share your temporary number with contacts who need it before you travel.
