Smartphone and Mobile Plan ($50-$100 for phone)

I already have a tablet for everything high end just need a Samsung galaxy s1 equivalent cheap Android smartphone for accepting calls and sending texts and downloading some apps for traveling and GPS etc on the fly.

Budget max $100 preferably around half that.

Doesn't maybe need to run the latest YouTube 1080p videos and games but stuff like maybe messenger for Facebook and gmail and uber and mobile banking and google maps for searching for restaurants and etc would be great.

Basically a phone from 2011 or around that spec.

I guess good battery life and removable battery would be ideal at least a few days per charge.

NFC would be an extra but definitely not needed for stuff like using opal and paying with Android pay or whatever other stuff nfc is being used for these days.

Don't care about the camera or speaker quality won't be using it for that at all I have a tablet for WiFi Skype calls and listening to music viewing media.
