How much that cell phone? - LG GD510 Cell Phone

I'm assuming that your cell phone works fine.

Your cell phone gets its signals from cell towers serving your cell phone service provider, e.g. Sprint, AT&T, Verizon, T-Mobile.

If you are in a building or elevator, your signal can be weak. Try going to the edge / side / top of a building, like by a glass window to see if the signal is stronger.
Or if your cell phone service provider (phone company) doesn't have a cell tower close to where you are, the signal can be weak or nil.
You can find out your cell phone company's cell tower coverage areas ...by checking their website. If you are at locations where your cell phone service provider has good coverage, you will get stronger signals. Otherwise, expect to get weak signals.
Yes, it's always prudent to check which cell phone service provider has good cell (tower) coverage in areas where you are (using your cell phone) most of the time, and subscribe to that company's cell phone service.

If your mobile phone is lost or stolen you can inform your cell phone provider with your IMEI number. Your cell phone provider can then put the serial number on a shared database. This list stops this particular phone from registering on any network and will be useless for anyone even if the mobile phone's SIM card is changed. It is not possible to trace your cell phone, even if you had setup a tracker program on the phone, it can only give the location of your cell phone in the coverage area where the cell phone transmitter tower is located.
Your best bet is to ring your cell phone and hope the person who answers your cell phone will return your phone to you.

A mobile phone jammer is an instrument used to prevent cellular phones from receiving signals from base stations. When used, the jammer effectively disables cellular phones. These devices can be used in practically any location, but are found primarily in places where a phone call would be particularly disruptive because silence is expected. A cell phone signal jammer is used to stop nearby cell phones from sending or receiving signals to and from the cell phone tower. A cell phone works by communicating with its service network through a cell tower or base station. Cell towers divide a city into small areas, or cells. As a cell-phone user drives down the street, the signal is handed from tower to tower.

Cell phone jammers block cell phone use by sending out radio waves along the same frequencies that cellular phones use. This causes enough interference with the communication between cell phones and towers to render the phones unusable. On most retail phones, the network would simply appear out of range. Most cell phones use different bands to send and receive communications from towers. Jammers can work by either disrupting phone to tower frequencies or tower to phone frequencies or both.

Cell phones are full-duplex devices, which means they use two separate frequencies, one for talking and one for listening simultaneously. Some jammers block only one of the frequencies used by cell phones, which has the effect of blocking both. The phone is tricked into thinking there is no service because it can receive only one of the frequencies. The jammer also stops Internet use through Wi-Fi network and even blocks Bluetooth connections. The cell phone signal jammer also puts an end to text messaging, so students cannot SMS each other, while the teacher is trying to teach.

Interestingly, jammers are life saving devices for military. Terrorists use cell phones to trigger explosives. Army can use a jammer to make mobile phones go dead, so that army technicians can deactivate the bomb.
