A:Answer Hi katmack, Thanks for your interest. If you look at our carrier compatibility list here: https://www.motorola.com/us/carrier-compatibility, the Motorola Edge is compatible with Spectrum Mobile (MVNO of Verizon ). However, we can't guarantee if Wi-Fi Calling will be supported as this feature is carrier-dependent. I would still suggest contacting your preferred carrier to check if the phone will work using their service. Lastly, you can add numbers on your keyboard by adding "Number row" under Keyboard preferences.. - Mike
