In this GigSky eSIM review, we explore how the service performs for travelers. From pricing to coverage, see if GigSky is a reliable option for staying connected on the go.
The GigSky eSIM is a digital SIM profile embedded in compatible devices that lets you activate a travel data plan without inserting a physical SIM card.
After selecting a plan via the GigSky app or website, you receive a QR code to scan or select the eSIM profile, which loads onto your device’s eSIM slot.
Once installed and activated, the plan connects automatically to a local mobile network partner in your destination, so your phone uses 4G or 5G data without relying on your home carrier’s roaming.
Your device must be unlocked and eSIM-compatible, which means it supports eSIM profiles; GigSky lists compatible models on their website.
You can install multiple GigSky eSIM plans for different regions on a single device and switch to a new device by scanning a new QR code. In some cases, transferring an active plan may require customer support assistance or reactivation.
GigSky is a smart choice for travelers and digital nomads who want easy-to-activate, data-only plans that work across many destinations worldwide.
It’s especially useful for those visiting multiple countries or traveling on cruises and flights where roaming is limited.
The service does not include traditional voice calls or SMS, and data speeds or coverage can vary by region, with limited ability to switch networks mid-trip.
GigSky offers prepaid, data-only eSIM plans starting at $4.69, with flexible options that vary by country and data allowance. These examples highlight random countries to show the range of pricing and coverage available.

GigSky’s wide coverage, mix of land and sea options, and easy activation make it a strong choice for travelers who want reliable mobile data wherever they go.
GigSky partners with leading mobile operators in every country it serves, providing reliable 4G and 5G data connections without the need for a physical SIM card. Once activated, the eSIM connects automatically to a trusted local partner network in your destination to ensure smooth coverage wherever you travel.
In the United States, GigSky operates on major networks such as T-Mobile and Verizon. In other countries, specific partner carriers are not always publicly listed.
Data performance depends on local infrastructure, with strong and stable speeds in cities that support streaming and video calls. Rural areas may have slower connections because of limited network towers or lower signal strength.
Users cannot manually switch between networks since GigSky automatically assigns the most suitable local carrier. This limits flexibility in some regions but ensures simple setup and consistent connectivity in supported destinations worldwide.
GigSky eSIM plans are data only, giving users instant mobile internet access for travel, work, and communication through internet-based apps like WhatsApp.
The service is designed for convenience, allowing travelers to stay connected without dealing with local SIM cards or roaming charges.
All plans support hotspot and tethering, so users can share their data with laptops, tablets, or other devices. This makes GigSky especially useful for families or professionals who need to connect multiple devices on the go.
GigSky eSIMs are compatible with most unlocked, eSIM-ready smartphones and tablets, including iPhones, Samsung Galaxy devices, Google Pixels, and select iPads.
Data performance is typically on par with local subscribers, providing stable and consistent speeds. While users can install multiple GigSky eSIM plans on one device, transferring a plan to another phone may require reactivation through the app or customer support.
Overall, GigSky’s eSIM features focus on simplicity, flexibility, and global reliability, making it a strong choice for travelers who want a smooth, data-focused experience.
On Trustpilot, GigSky holds an overall rating of 3.3 out of 5 stars from 466 reviews. Most users describe the experience as average to good, noting easy setup and reliable connectivity in major destinations. About half of the reviewers rate the service four or five stars, while others cite issues with coverage and performance on cruise ships or in remote areas.
A 4-star review from a traveler in Canada praised the service’s simplicity and fair pricing while using it across Amsterdam and Iceland. They said reception was good in both countries and appreciated how easy it was to sign up. However, they wished for better plan expiry alerts and easier access to account details like the eSIM’s assigned phone number.
In contrast, some users express frustration with cruise packages, where connectivity often drops once ships leave coastal areas. One reviewer shared that they were unable to get service at sea, even though they had purchased multiple plans for a week-long trip. They noted that the package expired earlier than expected and criticized the lack of real-time support while traveling.
Another low-rated review from a traveler on a Celebrity cruise between Turkey and Greece echoed similar concerns. They reported weak signal strength near the coastline, frequent disconnections, and limited customer support availability. The reviewer mentioned paying $90 for 3 GB of data but managing to use only a portion of it before losing signal.
Overall, GigSky’s reviews highlight strong performance for land-based travel, especially across Europe and North America, where users find it convenient and easy to use. On the other hand, maritime coverage and real-time support responsiveness are the main areas that users feel need improvement.
GigSky provides customer assistance through email at help@gigsky.com and in-app chat support via the Help Center. Their website also offers a detailed FAQ section that guides users through setup, troubleshooting, and data management.
The company states that email responses are typically provided within 24 hours, and many users mention that most basic issues are resolved efficiently. While the support team is generally helpful and knowledgeable, a few travelers note that response times can take longer when dealing with complex or location-specific problems.
The GigSky app is available on both iOS and Android and holds a 4.6-star rating on the App Store (3.6K reviews) and a 4.2-star rating on Google Play (1.8K reviews).
Both versions let travelers buy, activate, and manage data plans for over 190 destinations directly through their phones.
App users can view available plans, monitor real-time usage, and top up with just a few taps. New users can also claim a free 100 MB trial to test connectivity before purchasing.
Several reviewers highlight that the app is intuitive and easy to use once set up. One user from the App Store praised how well the service worked in the Bahamas, saying the connection was smooth throughout their stay.
Others found mixed results with cruise connectivity. One reviewer mentioned that the app performed well on land but failed to maintain service during a cruise, suggesting that cruise plans may be limited by distance from shore.
Android users also shared varied experiences. A user reported smooth performance across multiple Royal Caribbean and MSC cruises, highlighting steady LTE data and successful app use for family communication. Another found the service inconsistent on an Alaskan cruise, noting delays when reconnecting at sea.
Overall, users describe the GigSky app as clean, practical, and beginner-friendly, especially for travelers who want to activate data instantly. Some cruise and remote-region users reported connectivity gaps, but the majority agree the app delivers a smooth, no-fuss experience for land-based travel.
