Comment 5 for bug 1098685

We are also seeing multiple instances a day when users don't select their carrier even though they enter their cell phone number in the SMS notification area. Right now they are leaving it as the default, which is the first entry alphabetically.

I would like to propose that the carrier dropdown be set to a blank entry or a "Choose Carrier" entry when no user default is set. Along with not allowing the hold to be placed unless both pieces of data are entered.

Is javascript form validation frowned upon for something like this, or would that be a reasonable route?
