How to choose your international SIM card

Your international SIM card must meet your needs, which change depending on the type of communication to make and the phone used.

#1 - Your situation

The international SIM card is not necessarily suitable for all travelers. It all depends on the length of your stay. For a professional trip, this SIM card can do the trick, but the French packages are much better. No extra cost is applied throughout the use. Long-term travelers always turn to the best international SIM card. It is valid in several countries, so there is no need to change your card when you cross a new border. Expatriates don't need an international SIM card as much. A local SIM card is more suitable since they will stay in the destination country.

#2 - The format

Like all chips, this one comes in 3 formats. They are not the same size and require specific types of phones. The mini SIM card is suitable for GSM models. It has a storage space of 2 to 32 kb. The micro-SIM card is for high-end smartphones. With a size of 2.3 x 1.2 cm, it has a storage capacity of up to 128 kb. iPhone owners need the third version of the international SIM card. This is the nano-SIM, the smallest and also the most powerful card.

#3 - Related services

The operators give the opportunity to benefit from very convenient services, which are often available online. The card itself is ordered from the operator's website and is delivered to your home. There you can also find the rates of the proposed packages. They are different for all countries, it is more convenient to see them directly on the site. Refilling credits on the internet is also very convenient when you are traveling. In addition, all the charges applied are clearly displayed at all times.

#4 - Suggestions

And so it is possible to compare the packages on the internet, more exactly on the website of the operator in question. The price of each package is different, as is its content. The more expensive the package, the more credit and the number of initial gigas are more important. Also check the number of SMS that can be sent.

Where to buy an international SIM card?

Major operators such as Orange and La Poste Mobile include international packages in their offers. You just have to choose a personalized package to benefit from international calls and data up to 60 GB usable everywhere. The card can be purchased prepaid or unlimited on the operator's website or at its point of sale.

Another option, other operators, not telephone, offer international SIM cards of the most interesting. The number obtained is not French and can be used in several countries. These cards can be bought on the internet. The last possibility is to go to some supermarkets and tobacconists to find your SIM card before leaving.

The different types of international SIM card

Operators offer two types of international SIM cards.

International SIM card with calls

This international SIM card is intended for making calls rather than surfing the internet. The credits for calls are more numerous compared to the gigas. Generally, the number associated with these cards is valid in several countries and on all networks. This is very useful when you need to cross a border during your trip. Internet use is moderate with this type of SIM card. Check the validity of the credits at the time of purchase. The best operators offer reloaded SIM cards that are valid for months at a time to make your life easier.

International SIM card 100% Data

This one is for heavy data users. It's a good option if you use a lot of apps. Watching unlimited videos is not a concern, as the operators provide more considerable datas. However, be aware that the network the SIM card is used with is not the same. Some packages are exclusively for the 3G network, others, more expensive access easily and quickly to your applications and content on the Internet through the 4G network. The use of data can be limited to a day or counted over a longer period, a few months or a year.

International SIM card or local SIM card

International SIM card

The international SIM card is for travelers who go all over the world. It is operational in several countries. The goal is to allow users to keep the number during several trips. It limits their expenses whether it is for the purchase of the SIM card itself or for the recharges. The coverage extends to a hundred countries with this one. In addition, the cost of calls is very low compared to the rates offered by local SIM card operators.

Local SIM card

The local SIM card is characterized by a somewhat limited use. That is to say that it works only in a specific area. A French SIM card can only be used in the UK. You buy it once on the spot. You have to look for a store as soon as you get off the plane. Note however that it is not always that easy to get one. Some countries are more complicated in the sense that you need some documents, which are just sometimes impossible to provide in some cases.

Verdict

It is true that the international SIM card is more expensive than the local SIM card, but it is still more economical in the long run. Calls come back more affordable and you don't pay for incoming calls and texts. Then, don't forget that the tourist packages that go with the local SIM cards are very expensive most of the time. In any case, the privileges remain the same. You have access to internet and all the other uses of a SIM card whether it is international or local.

Why buy a (good) international SIM card?

To avoid data roaming

Data roaming allows the SIM card to work even abroad, in other words on a network other than its own. The problem is that this implies separate charges. This is where the problem lies, as they are never displayed beforehand or even while using the services. Consumers are therefore faced with the unpleasant surprise of seeing their bill rise once they return. This never happens with an international SIM card, as all charges are displayed and the card itself is intended to be used abroad.

No hidden charges

With the international SIM card, you have access to a history of all activities. It's easier to track all the charges that have been made because of this. Especially since all charges are mentioned beforehand.

To take advantage of local rates

Once you arrive at your destination, the rates are the same as those applied locally. No rip-offs, no extra costs. It's the best way to stay connected and communicate abroad while making big savings.

Delivery of the SIM card before departure

When you buy an international SIM card, you receive it before you leave. This saves you the time of searching for an outlet when you arrive in the new country. Then the card detects the network as soon as you get off the plane. This means you can make calls and connect to the Internet right away.

Easy recharging system

These SIM cards are already topped up and the credits are available for months. Some consumers don't even need to top up until the end of their trip. But it is necessary to do so if you stay abroad for a longer time. New credits can be unlimited. They can be accessed online.
