See one of the getting started examples for learning how to detect if a phone number is enabled for SMS. Here is the code snippet in Node JS.

async function read_extension_phone_number(){
    try {
        var resp = await platform.get("/restapi/v1.0/account/~/extension/~/phone-number")
        var jsonObj = await resp.json()
        for (var record of jsonObj.records){
            for (feature of record.features){
                if (feature == "SmsSender"){
                    return send_sms(record.phoneNumber)
    } catch(e) {
