What to do right now if you are out of internet in Europe
If you are in Europe without internet right now, first check if your cell phone actually accepts eSIM: many recent models do, even if you have never used it. If it really doesn't accept it, your immediate alternatives are a local physical SIM, roaming from your home operator, or a WiFi network while you sort out something more stable.
Follow this order: it goes from most likely to least likely to work in the next few minutes.
- Confirm if your cell phone really accepts eSIM. This is the most frequent mistake: people assume their cell phone doesn't accept it without checking. In the section how to know if your cell phone accepts eSIM we explain where to look in less than a minute.
- If your cell phone does accept eSIM, activate it immediately. The activation process takes approximately 1 minute once the eSIM is installed, and you can buy it from your phone's browser using data from another network (hotel WiFi, airport, or a companion's cell phone). Check the eSIM for Europe if you don't have one yet.
- If your cell phone doesn't accept eSIM, look for a physical SIM. Train stations, airports, and convenience stores in large cities usually sell them. More details in buying a physical SIM upon arrival.
- If you can't find where to buy a physical SIM at that moment, activate roaming from your home operator as a temporary bridge. It's not the cheapest solution, but it gets you out of trouble while you find something better. We explain it in activating roaming from your home operator.
- While you resolve it, connect to a public or accommodation WiFi network. This allows you to buy and install an eSIM, order a taxi, or send a message, although it is not viable for the rest of the trip.
Internet in Europe if your cell phone is not eSIM compatible
If you have already confirmed that your cell phone does not accept eSIM (not all models do, especially those more than five or six years old, or versions sold exclusively for certain markets), you still have ways to have internet in Europe without relying on it.
The most direct option is a local physical SIM: it is bought at the destination, placed in the cell phone tray, and works with any unlocked device, whether it is eSIM or not. It is the natural alternative when the hardware simply does not have the eSIM chip (more on when it is convenient, in the physical SIM section).
A second option, especially useful if you are traveling in a group or with several devices, is a portable WiFi router (known as MiFi or pocket WiFi): it comes with its own internal SIM, generates a local WiFi network, and any cell phone, tablet, or laptop connects to that network without needing eSIM compatibility. The disadvantage is that you add another device to carry and not lose.
The third option, and the least cost-efficient, is to leave your home operator's international roaming activated. It works on any cell phone you had configured before leaving your country, without additional procedures, but it is usually the most expensive option of the three because you pay international rates on your local plan.
What to do if you don't have eSIM: step-by-step guide
If your cell phone does accept eSIM but you don't have one installed yet, this is the easiest problem to solve of all, because it doesn't depend on finding a physical store or your operator having good coverage in Europe.
- Verify that you have some connection, even if it's slow. You only need data or WiFi for the moment of purchase and installation: hotel WiFi, airport, a cafe, or a companion's cell phone will do.
- Buy the eSIM from the browser, you don't need a previous app. Choose the plan according to the countries you are going to visit; if you move between several, a plan that covers the entire region is better than buying one per country.
- Install the profile by following the link or QR code you receive by email. The complete step-by-step, with screenshots by operating system, is in how to install an eSIM.
- Activate the data line and deactivate roaming on your physical line to avoid accidental charges from your home operator.
- Save the profile without activating if you haven't arrived in Europe yet. You have 180 days from purchase to activate it, so you can buy and install it calmly before the trip and activate it only upon landing.
If the problem is not the lack of eSIM but that the one you already have cannot get a signal, that is a different situation with specific causes that we cover in active eSIM but no internet: solutions.
What is the best way to have internet in Europe
There isn't a single "best" way for all cases: it depends on whether your cell phone accepts eSIM, how many countries you will visit, and whether you are traveling alone or with others. This table compares the five most common ways by the criteria that truly change your travel experience.
| Method | Requires compatible phone | Time until internet access | Do you need to go to a store | Ideal for |
|---|---|---|---|---|
| eSIM | Yes, eSIM chip | Minutes, bought and installed online | No | Travelers with a recent phone and multiple countries on their itinerary |
| Local physical SIM | No, works with any unlocked phone | Depends on finding a point of sale | Yes | Older phones or those without eSIM |
| Home operator roaming | No | Immediate if already activated | No | Short emergencies while you arrange another option |
| Portable WiFi (MiFi) | No, any WiFi-enabled device | Depends on prior rental or purchase | Sometimes | Groups or multiple devices sharing a single connection |
| Public WiFi | No | Immediate where network is available | No | Occasional use, never as a solution for the entire trip |
For most people traveling with a recent cell phone and visiting more than one European country, eSIM ends up being the option with the least friction because it is resolved online, without relying on finding an open store or going through procedures in another language.
How to get internet on your cell phone in Europe, step by step
Regardless of which method you choose, there is a workflow that prevents most surprises. It works whether you use eSIM or physical SIM.
- Before leaving your country: confirm that your phone is unlocked (not tied to a single operator) and check if it accepts eSIM.
- Buy the data plan in advance if you are going to use eSIM, taking advantage of the fact that you have 180 days from purchase to activate it; this way you don't depend on the arrival airport's WiFi.
- Upon landing, activate the data line and deactivate roaming on your original physical SIM before leaving the airport area, where there is usually free WiFi to make the change calmly.
- Verify that the new line is set as the primary data line in your phone's settings; this is the step most people forget and the most common cause of "I have eSIM but no internet."
- Keep your provider's support information handy in case you need help during the trip, outside of your home country's business hours.
How to know if your cell phone accepts eSIM in less than a minute
You don't need to search for the exact model online: the quickest way is to check directly in your phone's settings.
- iPhone: Go to Settings → Cellular (or Mobile Data) → Add eSIM / Set Up eSIM. If that option exists, your iPhone accepts it.
- Samsung: Go to Settings → Connections → SIM card manager → Add mobile data plan. This submenu often goes unnoticed because it's not under "Mobile Networks" as many expect, but specifically within the SIM card manager.
- Other Android (Pixel, Xiaomi, Motorola, etc.): Go to Settings → Network & internet → SIMs → Add SIM and check if the option "use QR code" or "eSIM" appears.
As a general reference, these are the model ranges that usually include eSIM in each brand:
| Brand | From which range usually includes eSIM |
|---|---|
| Apple | iPhone XS/XR onwards |
| Samsung | Galaxy S20 and Note 20 onwards (some regional models vary) |
| Pixel 3 onwards | |
| Motorola | Recent Edge and Razr models |
If your phone is older than these ranges, or it's a regionally locked version by an operator, check the detailed list in eSIM compatible phones before completely ruling out the option.
Buying a physical SIM upon arrival: when it is convenient and when it is not
The physical SIM is still a valid alternative, especially if your cell phone does not accept eSIM. It is convenient when you visit only one country during the entire trip and there is an accessible point of sale near where you arrive, such as the airport or an electronics store in the city center.
It becomes inconvenient when your route crosses several countries, because each border can mean buying another SIM, queuing again, and repeating the process in another language. It also complicates things if you need an identity document for registration (which is common in several European countries) and you don't have it with you at that moment, or if you arrive outside business hours and the store is closed.
If you bought an eSIM and it appears installed but you still have no internet, it is almost never a problem with the eSIM itself: the most common issue is that the correct data line was not set as the primary data line in the phone's settings.
You can further review the practical differences between both technologies in eSIM vs. physical SIM.
Activating roaming from your home operator: the emergency option
International roaming from your home operator is the least friction option because it requires no paperwork: you already have the line configured. That's why it works well as a bridge when you arrive in the early hours, there's no WiFi available, and you need to sort out something specific, like confirming an address or letting someone know you've arrived safely.
The problem is that it tends to be more expensive than other alternatives for prolonged use, because you are paying international rates on a plan designed for your country. Not all operators also provide the same coverage outside major cities. If your plan is to stay for several days or cross more than one country, it makes more sense to use it only as a temporary solution while you activate an eSIM or get a local SIM. You can compare roaming with eSIM in detail in eSIM vs. roaming.
Errors that leave you without signal in Europe even if you have a data plan
There are situations where the data plan is fine, but something in the phone's configuration cuts the connection. Before assuming the plan failed, check these points:
- Airplane mode was accidentally activated during the flight and was never fully deactivated.
- The eSIM line's mobile data is turned off, even though the original physical line does have active data.
- The primary data line still points to your original SIM instead of the new line, so the phone tries to use roaming instead of the new plan.
- The plan expired due to time or data consumed without you realizing it, especially on long trips.
- The eSIM was never activated within the available window: remember that you have 180 days from purchase to do so, but after that period, it becomes unavailable.
If you have checked all this and still have no signal, it is advisable to contact support before mistakenly buying a new plan: many providers, including PuraSIM, offer 24/7 support in all languages by email and WhatsApp, so you don't need to wait for an office to open in your local time zone.

Frequently asked questions
Can I install an eSIM in Europe without WiFi?
You need some connection, even if it's slow, to download the eSIM profile: remaining mobile data, airport WiFi, or a companion's cell phone will work. That's why it's advisable to buy and install it before traveling, when you have a stable connection at home, and activate it only upon arrival.
What if my cell phone doesn't accept eSIM and I can't find where to buy a physical SIM?
While you sort it out, use public or accommodation WiFi for urgent matters and consider activating roaming from your home operator as a temporary bridge until you find a physical SIM point of sale.
Do I need my phone unlocked to use eSIM or a physical SIM in Europe?
Yes. If your phone is tied to a single operator in your country, you won't be able to use an eSIM from another provider or a local physical SIM until you unlock it. Check this before you travel, not upon arrival.
Can I use the same eSIM in multiple European countries?
It depends on the plan you buy: there are plans limited to a single country and regional plans that cover several European countries with the same installed profile. If your route crosses borders, choose a regional one so you don't have to repeat the process in each country.
What is the difference between roaming and eSIM?
Roaming uses your home line and operator outside your country, with international rates on your current plan. eSIM is a new profile from a different provider, specifically designed for the destination, which you install alongside your main line without affecting it.
Can I buy the eSIM before traveling and activate it after arriving in Europe?
Yes. You have 180 days from purchase to activate it, so you can buy and install it calmly before the trip, keep it stored, and activate the data line only when you land.
What do I do if my eSIM is installed but I don't have internet?
First, check that the primary data line in your phone's settings is the eSIM, not your original line. If the problem persists, contact support: it's available 24/7 in all languages via email and WhatsApp.
What to do depending on your situation
If your cell phone accepts eSIM, that's the quickest solution: it's bought and installed online, activation takes approximately 1 minute, and you have 180 days from purchase to activate it when you need it, with coverage in more than 200 destinations if your itinerary changes at the last minute.
If you've confirmed that your phone doesn't support it, a local physical SIM or a portable WiFi device are your best option if you're staying several days in the same country; your home operator's roaming can serve as a bridge for the first few hours, but not as a solution for the entire trip.
And if you already have an eSIM but something went wrong along the way, before spending money on a new plan, check your data line settings: most cases are resolved there, and if not, 24/7 support via email and WhatsApp is available for that.
