Firsty: Surfing Unlimited by Watching Ads
Firsty offers a free plan called Firsty Free, which is ad-supported—similar to how YouTube or Spotify operate. You earn data by watching ads. Speeds are reduced (256 Kbps to 1 Mbps, depending on region), so it’s mainly useful for emails and messaging.
A major benefit is that Firsty Free is always available. Even if you have no data, you can open the app, watch an ad, and generate new data. The Uber app works fully with Firsty Free.
GigSky: 100-500 MB for 7 Days
GigSky has been around for years and was one of the first companies to offer low-cost eSIM roaming back in 2018. If you’re new to eSIMs, GigSky’s free plan is perfect to test the waters—no credit card needed. Just download the app, register, and get between 100 and 500 MB (depending on the destination), valid for 7 days.
Conclusion
The eSIM market is crowded and competitive, leading to ever-lower prices. If you’re flexible with providers, you can save real money with free credit offers. The deals from Yesim and Roamless alone can get you up to 5 GB of free data, depending on your travel destination.
