i have a MPX200 that i would like to unlock so i can give it to my freind. how do you unlock a cell phone, more specificially the above mentioned? someone told me you have to use a certain device? or is their a code? im willing to pay a reasonable amount to get this unlocked, or get a code.......whatever.

if you dont know, dont post..........but if you do, please!
its on the cingular system.

i know some people on here worked for cingular, i thought i would see what kind of answers i could get

 

What provider is the phone going to be used on?
If it is cingular then all they need is a new sim card.

 

I was gonna say use the "search" button, but I found the info.

or you can go to just about any young person who works at a cell phone shop . small one preferably. and pay them 20 and they'll do it.

 

its really easy, all you need is a data cable and the software that comes with it... i work at a cell phone accessory shop and we cant do it because we dont have a comp.. but head on down to any little cell phone shop and they should do it for like 20 bucks.

 

im lost , and i've heard this around ..but

what does it mean to unlock a cellphone ?

 

means that... say if you have a cingular phone, and you have t mobile service, that means that you have to unlock the phone so that you can use a t mobile sim card in your cingular

 

yes, its on the cingular system..........and it does not just take a new sim card, the phone itself needs to be unlocked.
it will be used on verizon

 

call your provider and simply tell them that you are going out of the country for a few and want to use your phone while you are out there.

cost = $0

 

yeah, i was told to do that.........im going to try it

 

Can I unlock a erisson phone, to use on the alltel or verison network? Does anybody know. Because those two carriers are so behind on technological advanced phones with talk times of more than 250 minutes.


I want a erisson or (w600) or something with at least 500 min talk time, for one of these carriers......... ALLTEL or VERISON..... So can you unlock phones for these too.? With out going back to CDMA style phones?

Who knows?

 

Some quick info about using phones across providers...

The digital networks are CDMA (code division multiple access), GSM (global system for mobile), TDMA (time division multiple access), and iDEN (integrated digital enhanced network). The advantage of CDMA is that many CDMA phones incorporate analog backup for roaming in areas where a digital signal is unavailable. Many GSM phones provide coverage in other countries, which could be a consideration if you travel for work or play. TDMA is an older system that’s no longer widely used, while iDEN is used almost exclusively by Nextel.

Verizon: CDMA and analog. However, Verizon offers analog access on few of its new phones, which could mean less coverage in some rural areas.

T-Mobile: GSM only. Many phones can be used outside of the U.S.

Sprint/Nextel: Sprint uses CDMA but can roam using analog. It may provide the best coverage in rural areas because most of its phones remain analog-capable. Nextel uses iDEN only. (Sprint will not generally allow turn up of CDMA phones not supplied by Sprint even if they will work on their network.)

Cingular: Primarily GSM, some TDMA and analog. Many GSM phones can also be used overseas.

I personally still use an older Sprint analog-capable CDMA phone with 450-480 minutes of talk time or a few weeks of standby on a charge. It has served me well, especially when out in the more 'rural' areas of the US of A and Canada.

 

Something to note: A phone designed for one network (like GSM) will not work on a totally different network (CDMA). So, if you have a Cingular or T-Mobile phone, you can't use it with Sprint/Nextel or Verizon. Sprint and Verizon can be used on each other's networks, but you may lose certain features on your phone. Cingular and T-Mobile are compatible, but again, you may lose some features. TDMA isn't really used much anymore, and finding a carrier that actually lets you purchase a new plan on that network will be difficult. It used to be pretty good, but has been in the process of being phased out. Analog will also be phased out in most areas.

Also, GSM phones use SIM cards. The phone won't work without one (except maybe to 911 and the operator). CDMA, TDMA, and I believe i-DEN do not use SIM cards.

Good places to get info about cellphones and service providers, check out www.wirelessadvisor.com and www.phonescoop.com I also hear that www.howardforums.com is pretty good.

 

thanks guys for all the info.........

 

OK, not meant to jack your thread but being this is a phone related question I was going to post, my wife and I are looking for a new cell phone for her. Being she's from Japan, she'd like to use her Japanese phone if possible. I heard there's ways to mod it to make a Japanese phone to work here in the US. Any information would be great.

Thanks.

 

no your not jacking the thread,.........yet. Super mod, good, post,...........its like I know this, but never could post a reply like that unless I cut n paste it.

So thanks.....

But........still, unlocking phones for The alltell or good GSM phones to verison.

Grant it I should start my own post, and so should the guy before me, but there room here for it, or other stuff with phones.............................

Hey mods, just think if you had to police a phone site and put those into the correct forums................... ahh well I guess its probably the same difficulty as a tc xA corner carvers ICE power hungry post too?

 

well the phone i just ordered a amotorola SLVR is from europe and is unlocked, so i assume it would be the same process, and have the phone your wife has unlocked, i would assume it would work

 

Tomas is correct only thing wrong is cingular no longer uses TDMA as of novemeber I believe...and it is possible to get a GSM phone to be used on a CDMA network but once its done you have lil to none support for it and 9/10 the phone cant be converted back. And you usually have to know someone that is a tech that can do it.

 

I know they have quad-band phones that support both GSM and CDMA, but I've never seen a GSM phone working on a CDMA network (or vice versa). They work on different frequencies and use different protocol. I don't see it being a simple chip mod or just a software upgrade.

 

Yup - with new wheels and tires...

Yeah, Peteyd, Cingular set a goal of changing over everything from TDMA by then, but I don't know for sure if they made it - and of course a lot of their older phones that no longer work on their networks are TDMA phones that might be for sale...

For those still unsure: the phone MUST use the same bands (800MHz, 900MHz, 1800MHz or 1900 MHz) and protocal (TDMA/GSM/CDMA/iDEN/Analog) as the network it connects to or it WILL NOT work.

Some phones are built to handle more than one type of protocal, most handle more than one band, but I don't think there are ANY that are "universal" - though that might be nice... (Closest I've seen are a few "quad band/tri-mode" models with CDMA, GSM, and Analog capability - essentially three separate phones in one case.)

It would be nice if the Japanese phones would work on US networks, but generally they won't, Orataro - they use slightly different bands and protocols. (There are some of the Japanese phones I'd love to have available here, but we only get about 20 nearly identical designs, and none of the neat ones - see http://www.tijil.org/blog/?p=12 and http://www.tijil.org/blog/?p=6.)

Bottom line is I guess I'm one of the "odd" customers who just wants a phone to be high quality and to reliably complete calls - I don't need a DigiCam/Internet/SMS/Audio Recorder/MP3/FM/AM/TV/Flashlight/Wireless Modem/Walkie-Talkie/PDA/VidCam/GameBoy, just a phone...
