It's important for us to be careful about what we throw out. As the earth's population grows and we all accrue more stuff over the course of our life, waste is a major environmental problem. By cutting down on how much stuff we use and how much waste we produce, we can have a really positive effect on the environment. We can actively help the environment by reducing, reusing and recycling. One of the ways people are helping the environment is through sim only phone plans. We produce about a billion phones every year, and as we upgrade to the new model or switch providers, we throw out millions of handsets. While handset manufacturers are becoming better and better at reducing the harmful materials in phones, many handsets still contain material that is bad for the environment. It is therefore important that we reduce the number of handsets being wasted. Sim only plans allow a person to change provider and get a new plan without getting a new handset. So instead of throwing out your iphone 5 to switch providers, just change your sim card. This not only helps the environment by cutting down on waste, but it also saves you a good bit of money. As a bonus, sim only plans are generally cheaper than handset plans, since with the latter you're paying for the handset too.
With the iPhone 5, Apple have taken a lead in reducing the amount of harmful chemicals in their phones. Still, it is a good idea for users to try to re-use the handsets through sim-only plans.
Of course, sim-only plans aren't going to save the planet all alone. It's important to use green energy, recycle and cut down on waste generally. But it's a good step in the right direction.
