QUICK ANSWER
For data abroad, you can use your operator’s roaming, buy a travel eSIM or get a local SIM. First check whether your current plan covers the destination; then compare total cost, days, data and compatibility.

| Option | When it may fit | What to check |
|---|---|---|
| Your usual plan | It already includes enough data at your destination. | Countries, usage limit, calls and costs after the allowance runs out. |
| Travel eSIM | You want to arrange another plan before departure. | Compatible phone, countries, validity start and high-speed data. |
| Local SIM | You are looking for a local plan during your stay. | Documentation, point of sale, installation, terms, and possible local number. |
| wifi | One-off connection in accommodation or trusted places. | Availability outside the accommodation and connection protection. |
1. Check the exact country, including layovers
List every place where you will need maps, messages or bookings. A plan labelled Europe or international does not necessarily cover all its territories. Also check whether a stopover involves leaving the airport. Do not assume a ferry, cruise ship or plane uses the same land-based network included in the plan.
2. See what you have already contracted
Log in to the app or your carrier’s customer area and check the destination, the data available and the out-of-bundle prices. If you already have enough included connection, you may not need to buy another tariff. For temporary trips within the EU, regulated roaming conditions and fair-use limits apply; check your case.
3. Compare the total trip cost
Compare products for the same number of days and countries. Distinguish between a total data allowance and a daily limit, and read what happens when high-speed data runs out. A one-week plan may be more suitable than a one-month plan for a short trip; a regional plan can make a route through several included countries easier.
4. Prepare the mobile with Wi‑Fi
Check the exact model and its purchase region, eSIM support, and carrier lock. Install following your order instructions and label the lines to distinguish the usual one from the travel one. Save the help and offline maps so you can consult them upon landing.
5. Choose which line uses the internet
Explicitly select the travel eSIM for mobile data when you want to start using it. Check automatic switching and roaming for each SIM separately. Calls and SMS on your usual number follow your operator’s terms; a data-only eSIM does not change those rates.
How Mundi eSIM plans fit
The current catalog includes Europe+, America, and Africa, with 28 days from the first consumption and 10 GB per day at maximum speed; after that, reduced speed. You have up to 90 days from purchase to activate your eSIM. If your home country is covered, do not use data there before you want the period to start. Check the updated price and the countries on each listing.
A check on arrival
With the mobile still connected to the accommodation’s or airport’s wifi, review the settings. Then do a small test with the travel line, such as opening a map. If it does not connect, check the troubleshooting guide before deleting the eSIM or repeating the purchase. Save the support contact so you can ask for help.
Frequently asked questions
How can I have internet without changing my SIM card?
If your phone supports eSIM, you can add a digital profile and keep your physical SIM. The number of lines that can be active at the same time depends on the device.
Do I need an eSIM for any trip abroad?
Not always. If your current plan includes the data you need in that country, you may be able to use it without buying another plan.
Does an international eSIM work in all countries?
No. Each plan has its own country list. Check destinations and stopovers before buying.
