You can actually get by pretty well if you live where there is good WiFi coverage. Once your contract is up you can use it as a WiFi only device. You mentioned you have an Android, and I've used a spare Android phone without contract for a couple of years as spare phone. To be able to text, IM, voice call, etc. pretty much requires that you use Google's services, but I assume that isn't a problem if you have an Android smartphone. There are a lot of VoIP programs on Google Play only let you make calls to other people with the same app, a la skype, but there are also some that can be used to call anyone. With one of these you can use a Google Voice account to make free calls over WiFi to whoever you want. I use GroveIP, but I also know a few people who use Spare Phone - VoIP Voice Calls. There are others, but those are the only two that come to mind at the moment. It seems that different phones work better with different VoIP apps, so you might have to try more than one. They cost a few bucks each, but that pays for itself in about 2 days off contract.
