to unlock your phone you use voice activation
It depends on the service provider. Remember, Nokia only manufactures cell phones; they don't provide cell phone service.
idk i have 2 cell phones. 1 is for picture and is not activated and another for full time usage. on my non active cell phone i have gotten a voice mail but could only check it on my active cell phone
You can't only on sprint or Verizon have mp3 built into their phones.
All the cell phones are working in DC only
Yes, there were phones. No cell, and only a dial type of phone.
Not all cell phones have GPS tracking chips. The only ones that have tracking chips are the smart phones, such as an iphone.
Cell phones chargers only match certain cell phones because it is a way for the cell phone company to make more money by forcing the customer to buy the corresponding phone charger.
Cell phones have only existed since 1973. See the Related Link below.
No
Not many cell phones have a hard disk installed in them. I can only think of Samsung SPH-V5400 and SPH-V7900.
Voice Activated Dialing (VAD): Being able to dial out on a cell phone or in-line phone via a voice command. There are phones that can be answered via voice, but others require activation of a switch (either remote or in-dwelling) before dialing out. VAD would allow a high level quadriplegic (someone who can only move their head due to a spinal cord or brain injury, but can use their voice) to dial out on a phone for emergency access. Evidently, there is a model of Blackberry that has the capacity to dial out via a voice command, but I have not seen or used it personally.
no, they are not, only phones who have the android system. For example, apple doesn't have android but most of the htc and samsung phones have android.
