I had some notice, and a more up to date rugged and waterproof phone is on the way, but until it arrives, hopefully wednesday, I am using this:
At least, it allows me to make calls and get texts.
I had to spend about an hour on the phone with Sprint tech support to activate the phone, because it is too old to do hands free activation.
Sprint was fine, it just took a while to escalate to someone who knew that the heck was going on.
