How to Get a Free SIM Card

1. Contact your cellphone service provider if your SIM card is damaged or no longer functions. You can visit a store, go online or call the service provider. If you have lost your phone, contact your cellphone service provider to get a replacement phone with SIM card.
2. Ask for a new SIM card if your phone still works but the existing SIM card is not working. If there is no sign of water damage, the company will send a new SIM card to you or install a new one in the store.
3. Purchase a new cellphone handset from your service provider. While it will cost money to purchase the new phone, you will get a free unactivated SIM card inside the phone packaging. If you want to add a new line to your existing plan and your cellphone service provider offers SIM-enabled phones, you will get a new phone with a SIM card that is ready to be activated. The cards are included in the cost of the phone or plan.

How to Triangulate a Cell Phone

1. Turn on the cell phone. A live cell phone is in continual relay with surrounding cell phone towers to ensure the strongest signal, meaning the phone must be on to send a signal.
2. Note the location of the signal tower receiving the strongest signal. Draw its coverage radius. You now have one point with a circle and know that the phone is located somewhere within that ring.
3. Add a second tower's radius and location receiving a signal from your cell phone. The overlapping between these two spheres narrows the choices your phone is located to two points.
4. Place the signal strength of a third tower receiving a signal from your cell phone with the other two. At the point where these three orbits intersect you have the location of the cell phone.
