Now here are some things you need to know on how to go about getting your "Cool Asian phone"
But before i go on, Im not responsible for any way shape or form, Im providing this info to use at your own risk. Im not responsible for any injury
What is an unlocked phone?
Unlocked phones are like a region free phone, you can use it anywhere in the world.
Where do i get one?
You can aquire one very easy now adays through the internet and various websites.
Make sure first of all the web-site is legit. But i reccomend going to cell phone shop at your nearest asian/china-towns etc. neighborhood. They most likely will have a wide arrange of phones.That way they can demonstrate the phone there make sure it works. I hear a couple of horror stories from people who ordered their phones on-line and recieved "bricked" phones (Bricked is a term used when some one is unlocking a phone and the process fails. the phone is screwed, it wont be able to function at ALL.
wont be able to turn on or off. like the quote "useless as a brick". so becareful.
How much do these phones cost?
Depending on where your getting the phone from,and how much you want to spend.
I have seen these phones range from $150 to $400.
What service providers can i use my phone with?
Which companys work with my unlocked phone?
Does my provider suppor these phones?
As far as i know the providers that use GSM phones are AT&T/Cingular (they are now one co.) and T-Mobile. As far as my knowledge goes, and all the research i have done
up to this point, ALL GSM phones are unlockable and usable with these US providers.
***If you use Sprint, Nextel, Verizon and any US based company you DO NOT have a GSM phone. You cant use an unlcoked phone with these service providers.****
What is a SIM card?
SIM Card: Subscriber Identity Module card
This basicly your ID card for your cell phone service provider, it has your service number, phone book etc. all that
data is in that little chip.
What is GSM?
Global System for Mobile communication
What is the diffrence in GSM or CDMA?
This may get a little confusing but ill explain it in the best way i can.
GSM carriers: Cingular Wireless, recently merged with AT&T Wireless,
and T-Mobile USA.
CDMA carriers: Sprint PCS, Verizon and Virgin Mobile.
(There are also several smaller cellular companies on both networks.)
Now just so you know GSM networks totaly own the world market.
This is where you implement choice, say you live in the USA, and you go out camping and your provider is say, sprint.But sprint covarage area does not give you signal where you are camping. But people with T-mobile phones do have signals in that area. So spring doesnt have service there but you suddlenly get a signal, but instead your phone saying sprint, its verizon. It called piggy-back networking. Even tho provider company is diffrent, the signal remains the same. Take a look at the service procider coverage area.
to put it in short, its covarage, thats what it means.
CDMA:(Code Division Multiple Access): A technology for digital transmission of radio signals between, for example, a mobile telephone and a radio base station. In CDMA, a frequency is divided into a number of codes. All tho there is no limit to how many users are on one connection tower, it does limit quality in the call, hense static, dropped calls.
***Notice that some of the GSM have digits next to them. (for example: GSM-900, GSM-1800, GSM-1900.)
Thats a digital network (working on that frequency) like a radio station signal.
How do i know if the phone is unlocked? .
There are serveral ways to find this out.
1. You can get your tech manual and punch in the program code that takes you to see your version of phone and you will see the part depending on what phone you have, each prosess is diffrent. it will show either "locked" or "Unlocked" next to the phones internal ID.
2. Ask one of your friends with a GSM phone sim card (make sure its a diffrent provider than yours). swap the card from their phone to your phone, turn it on.
If it has all his/her info and works it is unlocked.
****If it gives you an error screen and doesnt work or turn on then you dont have an unlocked phone****
How do i unlock my phone?
You can do it if you have a GSM phone, its like punching in a code to your phone.
Refer to your tech manuals or search on google to find out the specific steps to doing so.
Is it legal to unlock cell phones?
You bought it, payed for it. So you have every right to do what you like with YOUR cell phone.
This is somewhat not done and doesnt include all the info i will like it to have. But I will finish this up and clean it up in the near future.
