Whether you frequently travel to the end of the world for business meetings or if you’re planning to backpack across another continent, you'll need to consider how to get online, without blowing up your budget and having to get a new SIM every time you cross a new border.

Arguably, the best solution will be to invest in an international SIM card, an easy, hassle-free way to get online abroad, which often works out a lot cheaper than what one may imagine. Find out all the details below.

What is an International SIM Card?


 An international SIM card is a SIM card that enables to get access to the internet abroad, on any local network, without any price variation between one country or another included in your package. You can thus use your phone in France and a variety of countries, too.

 Depending on the brand of the SIM, it can either be charged up by purchasing credit or bought with a plan and a fixed number of gigabytes to be used.

 Thanks to this system, you can go online in over 200 countries with just one unique SIM card in your phone.

International SIM card or local SIM card: which is best for me?

While it is usually easy to get access to free wifi abroad in cafes, hotels and restaurants, it is can be a little risky to rely on it, plus it is rarely of good quality. To put your mind to ease, is thus recommended to arrive to destination with an already planned out internet solution.

Whether you're better off opting for an international SIM card or purchasing a local SIM card in the country you are visiting will largely depend on your reason of travelling and how long you need access to the internet in said country.

Below is a guide to which SIM will be the best adapted to you, depending on your situation.

Which is the best solution to get online abroad, according to my situation?

I’m a businessperson

An international SIM card can be a good option if you stay abroad long enough (a few weeks at a time for instance).

But in other cases, for short business trips, a French plan with international allowances will be better suited to your situation

Some of the major French providers, such as Orange, SFR, Bouygues or Free offer a wide range of international options in their phone plans, so as to get internet abroad at no extra cost.

To find out more about the different options and phone deals available to you in France, just contact Selectra at 09 77 55 72 27 or ask for a free callback.

This isn’t a well-suited option for you.

On a business trip, you rarely have the time and opportunity to purchase a local SIM card, plus you won’t be able to get access to the internet straight out of the plane.

I’m an expat

An international SIM card is first and foremost dedicated to people wanting to get online in over 200 countries, with sometimes special deals for a given country, but it may not be the best long term solution for an expat.

It will indeed work out a lot more expensive, especially if you can only access the internet without being able to call.

This won’t be an ideal solution in the long run either, as using a French phone plan abroad for over 4 months, as you will end up paying extra roaming fees after that.

These fees were set up as a way to prevent people from abusing the system by using their regular phone deal abroad. In this case, you’ll receive a message from your provider informing you of their intention to start charging you extra fees. After that, you will have 15 days to regulate your situation.

For expatriates, a local SIM card will definitely turn out to be the best solution for you if you are living abroad permanently.

Having a local phone number is also very handy and will make administrative matters a lot easier.

I'm a backpacker The international SIM card is ideal for you! It will be very handy if you’re planning to travel across several countries over a month or more, as you will be able to change the country without having to change your SIM card.

Using your French phone during your travels is another option, especially if you have subscribed to an advantageous international option. This could, however, work out quite expensive - beware of going over your allowance!

While roaming fees have been scrapped in Europe and the DOM territories since 2017, this isn’t the case elsewhere, so keep that in mind depending on which countries you are visiting.

A local SIM card can be an option, however, it will likely become a hassle to organise, since you will have to change your phone number and SIM card every time you enter a new country.

As demonstrated in these different cases, getting an international SIM card is more advantageous in some cases than others, it all depends on your situation. If you feel like this is the way you want to go, below are a few of the international SIM card providers available to purchase in 2019.

Staying in France for over 3 months?If so, it's worth signing up for a postpaid mobile phone plan. In the long run, these are cheaper than pay-as-you-go and offer better calling time/data allowances. Call our English-speaking customer service line at 09 77 55 72 27 (Monday to Friday, from 8 am to 9 pm and 9:30 am to 6:30 pm on Saturdays and on Sundays 9 am to 5 pm), or ask for a free callback to help you find a plan that meets your needs
