Review on 📞 KSUN ZL10: 4G SIM Card Walkie Talkie Phones with Long Range, GPS, WiFi, Bluetooth, and Two Way Radio Function by Vera Gashi

As others have said, I also use it with a group of hams on cello, excellent RX and TX sound, much better than a cell phone speaker. It came quickly from Arizona, the instructions are for another radio so it took me a while to get it working. For $60 it does what it's made for, just Zello. A good buy if enough. For some people who doubt our ham radio reports, my FCC license is KA9JYO.
