The Difference between analog and digital phones:

1. What's the difference between analog and digital phones?
Analog phones operate on an older and less effective technology. This technology doesn't scale well and is more costly. Analog service is not compatible with numerous new features.

Digital phones are lighter and more compact and have a longer battery life. When we are inside of a calling area the quality is better than analog. Digital phones support new features like caller ID, text messaging or wireless Internet services.

A Dual band phone is a phone that can operate on an analog and digital service.

Lithium-Ion or Li-Ion batteries have the longest life. They also happen to be the lightest in weight. The two pluses means there is minus attached, which is price. A li-ion battery will always be the most expensive type of battery available.

4. What's the difference between the Stand-by time and Talk time

we phone is in standby mode when we phone is on but we aren't talking. The power consumption is minimal and the phone can stay in this mode for a longer period of time. When we are using the phone we are using talk time. This consumes battery power at a much quicker rate. wer battery life will be somewhere between talk time and standby time

5. What is a roaming charge

A roaming charge is when we make a call from outside of our calling area. Our calling area is defined by plan local, regional or national.


6. What are peak and off peak hours
Peak hours are during the day when the cellular networks are very busy. These minutes are at premium and your plan will typically include the smallest amount of these. If we use more than your allotted peak minutes they will be billed at a much higher rate than off peak minutes. Off peak is the exact opposite of peak time. Each cellular provider has their own definition of off peak.

7. What are anytime minutes

Anytime minutes are simply put minutes we can use anytime, peak or off peak. On most plans we will use anytime minutes first.

8. Do I pay for the call when someone calls me

Usually yes. we are billed for the airtime when we receive a call. However some service providers are offering unlimited in network calls.

9. Should I buy a cell phone or look for a free cellular phone

Free phones generally speaking don't have the latest features, they are anywhere from 6 to 12 months behind. Also, free cell phones generally come with longer contracts. But, it is still possible to get a great deal on a free cell phone.

10. What to do if we would like to upgrade/downgrade or cancel yourr service plan

we can usually upgrade to higher plan without any cost. Some may force us to extend the contract for 1 to 2 years from that point. Downgrading the plan is often times not an option and when it is there is usually a penalty or fine.
