Great solution, fairly priced and works very well. Support is also prompt and professional. Highly recommended!!

Getting ready to travel? GigSky provides affordable data plans to over 190 countries, available straight from your iPhone using its eSIM which gives you a 2nd data line. Choose from 1-day, 15-day or 30-day eSIM data plans. Save over 90% off carrier roaming fees!. There’s a eSIM plan for every type of traveler.

Not sure what an eSIM is? Think of it as a digital SIM card. Rather than having to open, remove and replace you existing physical SIM card or displace your current domestic provider, the eSIM works via your phone’s operating system through our App. You can now keep your current SIM/eSIM installed while you travel and use a second, separate data service overseas. And no more paying too high roaming fees from your carrier.

Our eSIM data plans are really no different than any other prepaid plan you may have used in the past. You pay one low fee (in many cases much lower than your carrier’s roaming charges) and can easily top up throughout your trip if you need to. You get access to local data services at affordable prices without the need to hunt sporadic WiFi. You can also continue to use your existing phone number while using the data from your eSIM.

So who uses eSIMs? Well most everyone can. The full list of compatible devices can be found on our website, but any unlocked iPhone from 2018 forward has eSIM capability. It is the perfect solution for anyone who travels - it doesn't matter whether you're on a boat, a plane, on a business trip or you just want to enjoy mobile data while visiting other countries. We’re here to provide you with instant connectivity and solve your travel connectivity problems. With a selection of country-specific, regional and global plans – there’s a data plan for every type of traveler.

Need some additional information? You get:

- Global coverage: Regional, Country, and World plans with access to 190+ countries
- Instantly connect to global cellular networks through the app

Worked very well in Bahamas

We recently vacationed in a part of the Bahamas where local SIM cards are not readily available. I used this app to purchase a 15 day plan a couple of days before we left. I did not need to have the SIM card installed at the time I made the purchase. I installed the SIM card during the flight over and the service worked very well the whole time we were there. I was even able to use it for data while we were in the Miami airport on the way back before I had a chance to change the Sim card again. The app is not completely self-explanatory, but it was certainly usable. I’ll certainly be using it again.

Works well but coverage varies

I have been using Gigsky service for several years and generally I would recommend it over buying a local SIM with a few caveats.

GigSky is preferred if:
- you travel to different countries
- your data usage is moderate
- you check coverage before buying a plan
- you do not use iPhone Wi-Fi hot spot

Not advised if:
- you travel mostly to the same country
- you need over 1GB per week
- you do want want to change SIMs
- you need to use multiple devices

How to check coverage: arrive to the country of your destination and insert GigSky SIM into your phone. Wait a few minutes, you may need to restart the phone or at least enable and then disable airplane mode. Observe the carrier and data signals. If you are happy with signal and data then purchase a plan - typically you do not need Wi-Fi to buy data in the app however you *must have credit card on file* already. Use your card payment - Apple and Google payments work only on Wi-Fi.

GigSky introduced LTE SIMs last year. If you have an old SIM it is worth upgrading.

iPhone disabled Hot Spot feature is my biggest disappointment with this service. GigSky support claims it is controlled by Apple but really GigSky need to take charge to fix this problem. You cannot use USB sharing either.

My results by destination:
- Playa De Carmen, Mexico: no coverage
- Sao Miguel, Portugal: excellent, LTE
- Venice/Bologna, Italy: excellent, LTE

Developer Response ,

This issue has been fixed in version 4.1. Please uninstall your current app and install latest version of app.

Done with GigSky—LTE coverage is poor

I’ve been using GigSky routinely since the service was possible on the iPhone XS, first on that device then the 11 and then the 12. I’ve used it dozens of times in dozens of countries in Europe, Asia, North America, and South America. But I’m giving up on GigSky because the LTE coverage is spotty and often my phone is on 3G while my work mobile, which is roaming on the local network, at full bars on LTE. I’m tired of paying LTE rates for 3G service.

Sending a complaint to GigSky results in a circular discussion where I have to provide screenshots of the map where I’m standing and a variety of other information. Of course by the time GigSky replies I’m already in a new spot where it also doesn’t work. I’m tired of having to do so much work to prove that the coverage is poor, which GigSky already knows, and in dealing with excuses instead of solutions. Bye, GigSky. I’m off to FlexiroamX and Truphone.
