  • Every eSIM discounted by 15%, use FLIGHTCLUB15 as discount code and save, every time you activate an Airalo eSIM

We are all familiar with those little chips that are the SIM phone. When they were launched, it was the era of GSM technology phones, and they represented a small revolution: to switch one's number from one phone to another, one only had to take out the SIM card and insert it into the new terminal.

In this article:

    SIMs over the years have changed their appearance, Becoming smaller and better performing, up to the new eSIMs, which are basically dematerialized cards. This was achieved by integrating a kind of SIM card inside the smartphone that can be programmed multiple times through software.

    Not all smartphones have this feature, but the number of new models integrating this technology is increasing. Therefore, the time has come to becoming familiar with eSIMs and understand why these are perfect for one's travels around the world. I am a fan of this technology, and lately I have been expanding my list of providers and I also started to use Saily, not only because to all new customers, thanks to TFC15, you can have the 15% discount, but mainly because Using TFC10 always results in 10%.

    Specifically for travelers, the eSIMs represent a very viable alternative to buying a local SIM card every time you arrive in a new country. Of course, traditional SIM cards are still a widely adopted solution, but each time you have to buy it, show ID, choose a tariff plan in a currency with which you are not very familiar, wait for activation, and so on. Then, unless you own a phone equipped with two SIM slots, one must be careful not to lose one's main SIM card.

    Traveling with an eSIM means disembarking at any time of the day or night, even at a secondary airport in some remote nation, and having immediately the web connection. In addition, it is definitely easier to understand the type of offer in a currency with which you are familiar than to untangle the gigs offered, duration and various features in a currency completely different from your own. The eSIMs are activated autonomously, choosing a tariff plan that suits one's needs and selecting one's travel destination. One will be assigned a real phone number, usually provided by a local company, but most importantly, gigs of traffic with which to use messaging services, check one's email and make calls via WhatsApp.

    Even taking a trip to multiple nations becomes much easier: simply activate a tariff plan for the next nation you visit directly from the eSIM app. The cost? It often starts from just a few euros for a short term plan and enough gigs for the most common operations. You pay quickly by credit card and activation takes place within minutes, making it even doable in the last moments before departure, which are often a bit complicated for many.

    A eSIM resets roaming costs to zero, cannot be stolen or lost, and allows plans to be purchased even for short stays abroad, which would make the purchase of a traditional local SIM inconvenient. In fact, plans can be subscribed for as little as 7 days, for amounts that are often only a handful of euros.

    The market today is already saturated with proposals of all kinds, but there are some entities already better organized and proven by many travelers that offer convenience, ease of use, broad coverage and excellent customer service. Prominent among these are. Saily with its offerings and its discount coupon reserved for TFC readers.

    Finally, the function of web protection allows you to block dangerous sites and online trackers. Again, Saily promises not only faster but also safer browsing.
