Technology moves so fast it seems like you are always upgrading your cell phone. Rather than clutter up your junk drawer at home or worse, the local landfield. Recycle the old phone and charger which leach dangerous toxins like mercury if you toss them into the trash.
T Mobile accepts phones for all carriers to recycle and if you don't want to go to the store go to t-mobile.com/handsetrecycling to print out a prepaid label and mail it rather than trash it.
Also, several nonprofits such as the Partnership's Family Violence Center accepts phones on behalf of its clients at 1800 McCallie Avenue.
