What is an international SIM card? 

An international SIM card allows you to use internet services, text messaging and calling in several countries. The international SIM card works for specific areas, continents or regions.

They work by agreements reached between the company issuing the card and the local operators in each country.

An international data SIM cards does not work with an unestablished provider. If you connect with the incorrect provider, you must select the right network manually on your phone’s settings.

Can I avoid roaming charges with the international data SIM cards?

Roaming is expensive, regardless of which mobile operator you use. Using data roaming when travelling is not recommended. If you travel from the United States to Europe you can buy an international eSIM card and avoid paying for roaming.

Buying an international SIM card will help you avoid paying expensive roaming charges no matter where you travel. Bear in mind that each operator has classified countries by zones and you will be charged a different rate depending on where you travel.

If you’re from an EU country and staying within the European Economic Area, you can use data roaming within additional charges. You will be able to continue with your minutes, data and text messages just like home.

However, this only applies to countries within the European Union, so if you travel to the Balkans, for example, you might be charged an expensive rate. This applies to making calls as well as connecting to the Internet.

Roaming rates

The rates charged by Spanish operators to access the internet abroad are usually between $6.05 (USD) and $18. The most common price is $10 per megabyte.

For calls, prices are lower, but also expensive. When travelling to countries you are charged approximately $1 per minute. On the other hand, when travelling to destinations in Zone 3 or 4, you can be charged up to $6 per minute pe. These rates usually apply to both making and receiving calls.

As you can see, roaming when you travel abroad is expensive and an international SIM card will help you avoid these costs. The best thing is that with an international SIM card there are no contracts or subscriptions. Buy it, use it and recycle it – it’s as simple as that!

Advantages of an international SIM card for travelling abroad

To show you just how valuable international prepaid SIM cards can be, here are some of the benefits they offer:

1. Use the card in multiple countries

This is perhaps the main advantage of international SIM cards. They allow you to travel to several countries without having to change your number. Unlike a local SIM card, where you have to change the chip when you land or maybe look for it in shops, with an international SIM card, you land and you’re already connected to the internet.

2. Internet without contracts or signatures

The goal is clear. You want to access the internet when travelling and to return home with peace of mind and you already have a data plan in your country. There’s no need to fill out long forms or contracts with an international SIM card. In contrast, with a local SIM card, you might be asked for personal data, signatures, or your passport to activate your SIM.

3. Avoid surprise bills after returning from your trip.

You pay one up-front fee. use your SIM card without fear. You are in control of your data.  

Disadvantages of an international data SIM card for travelling abroad

Nothing is perfect and neither are international SIM cards. Here are the disadvantages of using an international SIM card.

1. You have to report your new number

When you travel abroad and need to communicate with your family and friends, you must inform them of your new number so that you can receive calls. To solve this problem, you can consult your operator and redirect incoming calls to your new number.

However, you can keep your mobile number for your WhatsApp and stay in touch with your contacts. WhatsApp is also free for both receiver and call, unlike traditional calls.

2. You won’t receive local SMS messages

You won’t have an international phone number with a data SIM card. So we recommend the international data SIM cards when you’re looking for internet connection rather than calls and messages.

Pocket Wifi is another option to connect to the internet on your travels. it allows you to share data between multiple devices and, most importantly: it’s unlimited.

But make sure to read the terms or conditions and small print on any restrictions. Sometimes, there are restrictions even if providers claim to offer the longed-for unlimited internet.

Look closely at the daily limit they offer, it is usually around half a gigabyte or 1GB. If you start watching a Netflix movie or series, you’ll be halfway through the movie and then left in the middle of the street without the Internet.

One limitation of Pocket WiFi is the number of devices you can connect to the internet. If you’re travelling in a group, it’s possible that someone will be left without data.

Be aware of these limits when using Pocket WiFi. Firstly, battery life will be extremely low  (you can rent a new battery for around €10). Also, remember to review the conditions in case of loss or theft, The price of the penalty can be €150 with immediate effect.

Sometimes sellers of pocket WiFi hide the shipping price, which could be between €8-10. You may also have to pay to return the device once your renting period is over.
