What is an eSIM?
Trusted by over 1 million users
An eSIM, or embedded SIM, is a built-in SIM card that's integrated into your mobile device's motherboard.
Unlike traditional SIM cards, an eSIM is non-removable, meaning you can’t lose it or accidentally leave it in the wrong device.
The technology is relatively new, but it's rapidly gaining traction across the globe, especially with the increasing popularity of smart devices and the gradual obsolescence of physical SIM cards in today's high-end phones.
The Future of Mobile Connectivity
As the world becomes more connected and mobile, the need for seamless and convenient data and voice connectivity is paramount. In the past, this involved the tricky process of swapping out SIM cards, juggling different devices, or managing various international data packages.
But what exactly is an eSIM, and how does it change the game for travelers, digital nomads, and tech enthusiasts? In this comprehensive guide, we'll explore the intricacies of eSIM technology, its benefits, and how it stands to transform the world of mobile connectivity.
Benefits of eSIM
eSIM technology brings the possibility of simpler, more flexible, and secure mobile connectivity. The elimination of physical cards and the convenience of managing profiles electronically make it a game-changer, particularly for those leading a mobile lifestyle. Whether you want local rates on a trip or the convenience of a second phone line, an eSIM makes it all possible.
If you're a frequent traveler, a tech enthusiast keen on staying at the cutting edge, or simply someone who values ease of use and security in their mobile experience, it‘s time to consider the switch to eSIM.
Unlock the world of possibilities that eSIM technology presents, and take the first step toward a more connected tomorrow.

Easy to use, worked well for me while staying for one week in the Bahamas. Took the free 100mb to confirm if it worked on my mobile and the 7day 1 Gb thereafter. Much cheaper and easier than buying a Sim card.
Mariana Sola
:
It was a great service and easy to use and install. I would use it again.

Have used GigSky with several devices in the Dominican Rep. and it has
worked great each time.

Installation is easy with the provided instructions. Once you have set up the eSIM, you don't have to reinstall it when you buy future packages.
Just make sure to not delete the GigSky eSIM, or you have to ask them to re-enable it.
For me the big difference with other eSIMs is that GigSky will use any available provider. Other companies have a contract with only one provider, often one of the cheaper ones that may not provide coverage in rural areas. So far, GigSky worked very well in rural Bolivia and Argentinian Patagonia. One day, two providers went down in Ushuaia, but GigSky didn't miss a beat, as they just switched to the last working provider.
Highly recommended if you travel to off the beaten path areas!

I've tried other E-Sims and they just don't compete. I always get great strong/fast service. They price is already affordable AND on top of that they promotions and coupons AND every time you purchase data, you receive credit towards your next purchase (further lowering cost). Thank
you Gigsky for making my travels so smooth!

I have used GigSky for a number of international trips including India, Vietnam and Europe. While other travellers had trouble with reliability of their eSim company, I did not experience any issues with GigSky. The "Europe" package allowed seamless access between countries. Tip is to turn off roaming for apps that you don't access while travelling to
ensure data isn't used unnecessarily. Easy to install.

Purchased to use in Bali. I had previously purchased with another esim provider which failed to work. Not one problem with GigSky.

I was having trouble with Airalo so opted for Gigsky as an alternative.
The eSIM was simple to set up (though I would consider myself reasonably tech-savvy; may be harder for people of an older generation) and worked great for a few days.
After 3 days or so my connection just dropped out and despite lots of tech support articles online, I was unable to fix the issue myself so reached out to the support team at Gigsky. They replied nearly immediately via email and within a couple of hours they had it working again.
If I need an eSIM in future I will be sticking to Gigsky.

GigSky was easy to use and we went to several countries and was very helpful providing internet access wherever we went. I will use it again on my next visit to Europe.

FAQs About eSIMs
Is My Phone Compatible with eSIM?
The first step to adopting eSIM technology is to ensure your phone is compatible. Although eSIM adoption is growing, not all devices support this feature.
How Do I Transfer My Existing Number to an eSIM?
The great news about using a GigSky data plan is that you don’t have to worry about transferring your existing number! GigSky plans are all data-only, which means you won’t be able to make traditional phone calls or send SMS text messages. This means there’s no new phone number to remember and you don’t have to transfer your phone number from your carrier.
If you need to receive calls or texts while on your trip, your phone number will still be able to do so – though some fees may apply. If this doesn’t apply to you, the best way to make sure you're not roaming on your domestic service when traveling is to turn off or remove your domestic carrier's SIM/eSIM.
Where Can I Get eSIM Plans?
GigSky is your one-stop-shop for eSIM plans. Whether you’re headed to a single country, off to explore a particular region or are jet-setting around the world, there’s a plan for you. Plans start as low as $3.99 and offer a variety of data options and validity lengths.
