May be the best e-SIM option for traveling. The ability to sell back your unused credit, use it in many countries, and for credit to last a whole year is a game changer compared to standard providers. The Dent concept is genius and I really hope it continues to do well - because it's great for us customers. First time users, note: it is very helpful to switch on your Dent eSIM before you leave home.

No esim installed after setup. The UI shows esim profile installed. And my account has data. But my pixel doesn't show dent esim at all. Not usable. Update: emailed the support and they sent me a qr code. That reenabled my dent. Thanks 🙏. Although it could be more convenient if I could reinstall the esim myself from the app, this is good enough for me.

I see people rating 1* and making all sorts of complaints and negative comments and I just laugh and wonder if it's the same app I've been using for over a year now. The Dent app is not a get-rich-quick app. The app makes it possible to buy, send and sell mobile data from around the world. And it has the After Burner program that gives you free call units. If you experience a glitch once in a while simply contact their support. They're very responsive. Add Nigeria to the exchange = get 5*. 😎
