i recommend through a phone carrier because you can get better advice and choose the phone that is best for you. The service is also better.
A branded cell phone is a phone sold exclusively through one carrier. The cell phone will usually have the carrier's logo/brand on it.
You can purchase a new blackberry phone through cellphone carrier sites such as att or verizon. Also sites such as ebay and amazon sell them as well. You can also buy them at brick and mortar stores.
Depends on your carrier i would go to used phone store if your out of contract of get them online off ebay or amazon
You can get your cell phone unlocked through the cell phone carrier you are subscribed to. For example, if you are with Wind Wireless, there is an option on the website to unlock your phone.
No. Each carrier has allowed cell phones for their carrier. If you have a GSM carrier though, you can buy an unlocked phone to use on that carrier even if the carrier doesn't support the phone. All you do is move your sim card.
The best way to find more information about one's phone is through the carrier or store at which one purchased the phone. The official website of the carrier or brand of the phone is another great way to gain information.
You can get a replacement battery from an online store such as amazon or locally from any of the cell phone stores in your area. It doesnt even need to be the same carrier as long as they stock the same phone.
I'm not sure of the context of your question, so I will assume you are asking if you can activate a cellular phone in the US, as opposed to activating a US Cellular phone (which is a wireless network in the US). Here are the different scenarios on activating a cellular phone in the US:Activating a carrier-based phone with the same carrier--you can activate a carrier-based phone with the same carrier, even if the phone has been inactive for a long period of time. It is functional provided it can connect to the current bands in that network.Activating a carrier-based phone with another carrier--if the phone is locked (tied to a particular carrier), it will not function if you attempt to activate it with another carrier. If you are able to get the phone unlocked (either thru the carrier, manufacturer, or on your own), it might work with another carrier provided the phone can run on that other carrier's network bands.Activating an unlocked phone with any carrier (traditional and pre-paid)--most unlocked phones, and this is assuming they are designed to be used in multiple bands in the US and/or elsewhere, can be activated on most carriers.Activating a carrier-based phone with a pre-paid carrier--it is possible to activate a carrier-based phone with a pre-paid wireless carrier, assuming that carrier has bands that match what the carrier-based phone had previously. An example is the pre-paid carrier Straight Talk, which utilizes bands from the four major wireless carriers (AT&T, Verizon, T-Mobile, Sprint).
Online you can buy a cellular phone amplifier at Amazon. Offline or online try Best Buy or another electronics retailer. Also try a mobile phone store for a specific carrier.
Almost all cell phones are attached to a carrier and so can only be reactivated with that carrier. But if the phone was reported lost or stolen, the carrier won't reactivate it for you. A little investigation is in order. First try to determine the mobile carrier the cell phone was registered to. The name of a carrier--such as T-Mobile, Sprint, AT&T, or Verizon--might be printed on the phone or may come up on the opening screen when the phone is powered up. Now look up that carrier's toll-free phone number. Now, with the phone off, remove the phone back and battery and look for the phone's serial number, or ESN (Electronic Serial Number). Next call the carrier and work through the menu until you get a live person. (Often if you select the "cancel my service" option, you'll be connected to a real person.) Explain that you've found a phone and give them the serial number. The carrier can tell you if the phone has been reported lost or stolen or not reported at all. From there you can decide what to do with the phone.
Answer tones can be purchased on most cell phones under the cell phone online menu.Depending on your carrier and type of phone will depend on the price you pay.
4G refers to the carrier not the phone maker ... and the carrier for that phone does have a 4G network...
