5 stars: Easy to use, support is pretty quick whenever there is a problem. I used it in foreign countries to receive calls and worked well as long as there was data service. Only had a few problems here and there but for the most part works well. The app sometimes doesn't like Bluetooth headsets, call quality is dependent on data service quality.
4 stars: App is good with good support. I downloaded and activated an esim so I could use it my other smart devices for work purposes. I wanted to use not for the calls but rather text messages. While calling, other person can see the number allocated to you but if you send text messages they will receive a random number and they can't reply to that. Moreover, unwanted notifications that you don't need.
4 stars: It's pretty awesome experience with the app once you understand it and the logic behind an eSim card. You will definitely love it since you are looking for a number on the E-Sim card programs and this app is a wonderful one to use and I would definitely recommend it to my friends, it is very affordable for everyone.
3 stars: I've been using Numero for a month to receive international phone calls. I can say that it was working for me perfectly until they removed the Bluetooth feature. Maybe it's just on my phone but I can't use my Bluetooth connected headphones to talk on the app anymore. I work as a driver and hands free calling comes in handy for me. I hope that this feature is brought back if not j will have to ...
