GigSky vs Airalo feature comparison
Now that you’ve had a quick look at general features, let’s see how GigSky’s and Airalo’s features hold up with an in-depth comparison.
App experience and setup
GigSky and Airalo both offer an app for setting up, installing, and activating your eSIM plan for use.
GigSky’s app activation process doesn’t require you to input your credit card information to start using the provider.
You can download the app, choose a 100 MB plan for free, and then install the plan by scanning a QR code that you’ll receive in your email. You won’t need to re-install your eSIM once you run out of data.
Airalo’s app offers a process that is quite similar to GigSky. You can view destinations, plans, get, and install your eSIM. However, you will need to enter your credit card information to make your purchase.
Pricing and data plans
Some GigSky packages even go as low as $3.99 for 1 GB of data lasting 7 days, while Airalo’s cheapest 1 GB for 7 days plans are $4.50.
This said, some Airalo destinations include a free trial of up to 1 GB valid for 3 days, while GigSky’s free eSIM only offers 500 MB for 1 day.
GigSky’s pricing varies quite a lot between destinations, while Airalo has a more standardized approach. For example, their 7 day, 1 GB plan for Greece costs only $3.99, while their 7 day, 1 GB plan for Mexico is $5.99, which is ultimately more expensive than Airalo’s standardized pricing.
GigSky also has Cruise + plans to keep users connected on cruises. However, these packages are more expensive. For example, their Americas and Caribbean cruise eSIM data plan is:
- 512 MB for $19.99, valid for 1 day
- 1 GB for $34.99, valid for 7 days
- 3 GB for $63.99, valid for 15 days
- 5 GB for $89.99, valid for 30 days
