Any suggestions?
No point in buying a cell phone you don't want. You could get a cheap GPS bike computer instead, e.g:
Amazon.com : Bryton Rider 310 GPS Cycling Computer (1.8" display, 310E - Base Model) : Sports & Outdoors
Benefits are that you get everything you want, along with much better battery life and no monthly fees.
