Hi All,
I was wondering if I could use my unlocked 8525 with Verizon's net work if I switched to them? I'm not sure about compatability of the phone with Verizon's voice and data services and was wondering if anyone knew.
Thanks
I dont think so. Att and verizon use two different technologies. Att uses GSM and Verizon uses CDMA. Im almost certain tho a phone that is based on GSM cannot be used on a CDMA network. The phone will work on TMobile or USCellular. They use a GSM based technology. Verizon Sprint and Nextel all use CDMA. If i am wrong and you can use the GSM based phone with Verizon CDMA then someone please correct me. But i am pretty certain you cannot.
OK,thanks. Thats what I thought
Verizon does not have sim cards, is that correct?

Not that I've ever seen.
I know sprint phones have sim card slots, but they are not used, at least in the USA.
My guess is that CDMA phones can be used in the same way as GSM phones as far as switching sims to use different carriers, but the CDMA carriers in the 'states don't use that functionality (probably to keep a tighter grip on their sucke....customers and wring more money from them through phone sales/upgrades and extra services, like a data service to put on extra ring tones )
I know that I don't know much about these phones, but what of the setting inside of Settings/Personal/Phone/Band where you can select WCDMA as your network type? I've got an 8525 and it shows as an option, but I just don't know if anyone's tried it before.
CDMA and GSM phones are totally different. The only SIM based verizon phone that Ive seen its the Blackberry 8300 its world edition soo it can bu used through a cdma and also a GSM carrier. I would be interested if anyone knows how to say make a sprint phone capable of being on verizons network. That would be something different.
actually a sprint phone is capable of being used on verison network any cdma phone is. in short the way cdma works the subscriber info is assigned to the phone's esn by the carrier so only the carrier can change your phone with gsm the sim (Subscriber Identity Module) holds the subscriber info and it is assigned to a sim card id not a esn (electronic serial number) so all you have to do to get a sprint phone to work for verizon is get verizon to let it (GOOD LUCK WITH THAT) you would have better luck the other way around verizon is the pickiest co out there when it comes to network integrity and security issues they seem to think that letting people use any phone they want could somehow hurt their network

WCDMA is 3G. 3G on GSM systems is essentially a CDMA standard, but not the same CDMA as Verizon uses. It is not compatible.

Hi
my sister bought from US a verizon xv6900 and now I want to use it in a different country?is it anyway to remove this cover on slot and insert a sim in it or the sim card slot is not working for this device?
thank you for your helps.
No, there isn't. An xv6900, and most phones on Verizon's CDMA network, do not use a SIM card. You will not be able to use this phone in Europe. There are no Verizon compatible networks there. Some of Verizon's phones have both a CDMA and a GSM radio in them, so they will work on both types of networks. The xv6900 is not one of them.
Verizon uses a cellular technology called CDMA, which is completely incompatible with the technology used in Europe, GSM.
ok....bad news
thank you very much...
i have HTC Touch Sprint I need program to unlock sim to cdma
I am pretty sure CDMA carriers do not use SIM cards. So I do not understand what you want to do with a SIM card.
You cannot use a SIM card with the Sprint Touch.
Ok, so i was explaining to my lil sister about sim cards, and as i was saying how only Verizon worldphones had sims, i realized that you could, in theory, put a Verizon 4g sim into a 3g worldphone, and.... what would it do? I'm a little hazy on how exactly Sim cards work, but would it be possible to artificially "create" a 4g phone using a 4g Verizon sim?
EDIT: ok, since there are no answers, i realize this is a noobish question, but does the sim card contain the actual 3g/4g/whatever radios, or does it just "enable" them?
The sim card contains the customer account information, so once you lock the signal verizon knows how to properly bill you for your usage.
4G sim cards are different than 3G sim cards although they are in the same format. You can't just swap your Droid 2 Global Sim card and expect to work in your Droid 3 or vice versa becuase the ESN is what is tied to your number, the sim card is just there for roaming purposes (i may be wrong on that one), but i know that even on the global phones, you must have the sim card inserted in the phone to be able to get service with verizon.
The 4G sim card works more like a REAL (GSM) simcard you can swap your sim card into another 4G device and your number will transfer.
Here is another difference, the same sim card on global devices can be reused like you can go to your account and transfer your phone to another account without the need for another sim card. The 4G sim cards become invalid once they are deactivated and you will require a new blank sim card in case you want to activate your phone number again (this usually happens when you switch from a 4G device to a 3G, then move back up to a 4G device), they work much like most GSM sim cards work.
So in sumary, the 4G sim cards works more like a real sim card.
hi guys,
have a nice day
please help and tell me how can i use a cdma sim card working on my samsung s4 sprint sphl720
,
because i had unlock the gsm card and make it work and now i need to unlock the cdma sim card to work
also i had to unlock the cdma and change spc to 000000 and confirmed with getmymsl program that the spc is 000000
also i add my country prl and the signal is good
the problem that when i put in the cdma sim card it doesn't work at all even on the cdma network or lte/cdma network and i don't know what should i do to make it work
my rom is 4.2 and my modem is mdl
my second question is how to add a language on the phone.
thanks and best regards
There is no cdma sim card. It is a cdma phone there is no sim for that. The sim card that is in the phone is for LTE and GSM.
hi friend thank you for your answer but there are cdma sim cards available in some countries except us.
and I know one of my friend use a cdma sim card in the s4 sprint and working good just like verizon phone . it accept cdma sim cards
but the problem I dont know if I should program first or unlock it first.
so I ask you guys to help to find the way to use cdma sim card on the phone.
thanks
I'm pretty sure cruise is right here... No such thing as a cdma sim card.
