2G Phones are phones that use second-generation wireless technology that is “digital” in comparison with 1G technology that is “analog”. When 2G was first introduced, the three main benefits it had were that conversations were digitally encrypted, the efficiency of the system led to increased cell phone usage and it facilitated data services such as SMS (Short Message Service) on mobile phones. Newer technologies have entered the market since then, such as 3G and 4G, although 2G is still quite popular in certain parts of the world. Listed below are a few questions answered by the Experts on issues related to 2G phones.
What is the best way to do a soft reset on an iPhone 2G that isn’t charging?
This is a very simple process. Press the power button along with the home button and hold them down for a while till the phone screen comes completely black. As soon as the apple logo appears, release the button. Charge it and check if it works.
Besides setting an iPhone 2G back to factory setting what can be done when it has problems making calls?
One of the simplest ways to tackle this is to sync the iPhone with iTunes and make sure that all the available updates are downloaded and installed. In most cases there should be about 10 to 15 updates for 2G. Once all the updates are installed, it should sort the problem out.
What is the best way to locate the firmware on a 2G iPhone or take it off emergency mode without a SIM card?
Typically, the only way to get it out of emergency mode would be to activate it using a valid SIM card. Get a SIM card from someone who has the same network provider and insert it into the phone. Once it is activated, remove the card and the phone should continue working till updates are installed.
What is the steps to get an iPhone 2G to switch off?
Case details: Have tried pressed both buttons together to try and reset it
To get the phone to reset, hold both buttons down at the same time for a duration of about ten seconds. Release the buttons the moment an apple logo appears on the screen. Once the phone restarts, it should work normally and switch off when needed.
Can 3G be disabled and then use 2G to minimize radiation on a Blue Earth phone since the radiation levels are low?
Case details: Service provider – AT&T
Generally, since both the 850 and 1900 MHX bands are used by AT&T in the United States for 2G as well as 3G there may not be a huge radiation difference if the two bands are compared.
In some cases, the power in the phone may need to be increased to compensate for a poor signal and pick up a 2G signal in places where a 3G signal is available but has been deliberately switched off. By doing this, the radiation levels would automatically go up.
A better option would be to change the way the phone is used. For example, do not place it to the ear. Instead, use a wired headset to lower radiation. Remember that Bluetooth is not helpful either since it is another device that uses radio
There are advantages and disadvantages to using 2G depending on the cell phone usage and needs. While a few questions regarding 2G phones are discussed above, there could be others that are specific to each case.
