Also own a Motorola Edge 40 Neo. Ofcourse it’s not the best Phone on the Market but it is quite fast and has plenty of battery capacity. I think if you buy it on a Sale it get’s you an awesome bang for your buck.

Are you using a different Tetra than anyone else? Because every radio i have used takes at max 1-1,5s to establish communications?
