With technological progress, the times when any user would turn to their telephone operator, with their mobile phone in hand, ready to temporarily remove the battery (for some devices it was a necessary operation) and insert the sim card equipped with a relevant chip to be able to use the device for calls and so on.
What are eSims?
For some time now all this has been replaced by eSim (embedded Sim) that have a mobile chip already incorporated into cell phones and tablets that can be “rewritten” and updated directly with wireless. The advantages are enormous: when you change operator you will no longer have to buy the physical SIM card and replace it but you will simply have to change the software settings. Even in Italy they are not yet so widespread, they are already present in the territory and above all they can give a great hand in terms of vacation And trips.
What to do for abroad
Given the season, it is very important to plan a few days of vacation beyond national borders and eSims can help in this sense by being able to take advantage of different operators with different offers based on the country you intend to visit but also on the package (if data or voice traffic is more important). It is not possible to make an overall estimate on prices because the proposals of the various companies are very vast and varied and suitable for all budgets. Industry experts also recommend a “reverse” search, that is, by inquiring with the telephone operator of the country you are going to visit.
The most used operators
Among the companies that aim to provide advantages on international roaming there is Airalo that has already satisfied the needs of about ten million users managing to cover 190 countries. The offers are divided into local, regional but also global eSim: you will only have to choose the destination and from there on take a look at the various offers. Another telephone operator is Holafly, very well known and used that does not require registration, promises stable and fast connections and customer support always operational also in Italian.
Saily, on the other hand, is an eSim compatible for more than 150 countries and over a hundred devices, easy to install and with the ease of renewing the Internet connection if it runs out before returning from the trip. GigSky, a mobile technology company based in Palo Alto, California, is added to the list, which offers various telephone plans but also checks the most suitable one when traveling on a cruise. Finally, here is Ubigi which in addition to eSim for international travel offers global cellular connectivity solutions for many cars giving the possibility of connecting to the Internet directly on board the vehicle.
Compatible devices
Although it is very convenient and used, not all smartphones have the ability to activate the
eSim: to find out if your device is compatible you will need to go to Settings, Mobile: if you find the item “add eSim” just follow the instructions to activate it with Qr code and follow the instructions.
