Is it possible to a CDMA diamond work on GSM?

hey guys, my friend bought me a diamond in canada which works on CDMA network, and where i live there is only GSM network...
is it possible to unlock it somehow?
if anyone knows please help me.
thanks.

Nope, not a snowball's chance in hell. CDMA phones don't use SIM cards, nor will they ever support the insertion of a SIM card, so it'd be useless on your network. Sorry.

You are partly wrong on this about not using SIM card at all. Yes, CDMA phone will never work on GSM unless, there's also a slot on the CDMA phone for SIM card, like some of those international phone sell by Verizon and sprint awhile ago. Now, there are some CDMA phone that are selling in China that actually use something similar to SIM card, called USIM. Hell, even the KDDI au from Japan use SIM card, and they are CDMA network too...

thank you guys that was helpfull

the phone is SIM unlocked; you can use on any GSM carrier.

Refrase...

I'm almost positive that you should be able to pop in any sim card, pre- or post-paid, and it should work...

i just tested it with a nextel chip with a plan but no data service and i still get no bars??? i will try to put up some pics....please help if ya can...thanks

As far as I know Nextel doesn't use GSM networks it has it's own iDEN network, I don't know what the difference is, or if it should work with a GSM receiver but I can't say I'm surprised it doesn't work. Also from what I've heard, the phone has only received FCC certifications on T-Mob and AT&T for the phone you have, Verizon passed separately. Again, don't know if this helps, but I'm not shocked it doesn't work. Your phone is carrier unlocked, it came that way from HTC and unlocking the bootloader has nothing to do with which carriers it will work with.

no all i did was i bought it on a tmobile network through google then i had unlock the bootloader then rooted the phone now is there a way to use differ carriers??? i did not buy it unlocked......from google.....so is there a way ?

Dude... your question is moot! The phone, even if bought on a T-mobile line, IS NOT LOCKED TO ANY SPECIFIC CARRIER! You can pop in ANY GSM SIM CARD, and it will work. I bought mine on a T-mobile upgrade... but I can throw in an AT&T, Rogers, Fido, Vodaphone, etc., SIM, and it will work just fine.

o okay will try it out with att thanks...

[Q] got a d3 today but issues about country

hi today my bro purchased a d3 which is not activated its a verizon one....so the seller told him that he can activate the phone from his verison sim and then ask them the unlock code to use it outside of usa...
so my bro is gona send me that phone to india so is it gona work or we screwd up lol...
or is there any possible way to make phone work phone is stil in usa and now what shold be done ?hope it works in india

What GSM frequencies does your carrier use? I think the only restrictions on GSM are US carriers/
Sent from my DROID3 using XDA App

freq
GSM 900 5 carriers
GSM 900/1800 these i found from google.. here i phone 4 works
and the bands of i phone 4 and d3 are nearly similar i think
i phone 4 -GSM/EDGE 850/900/1800/1900 UMTS/HSDPA/HSUPA 850/900/1900/2100
d3-GSM 850/900/1800/1900 (Quadband) HSDPA 850/1900/2100
i hope it works...
and one more thing the phone which my bro has is still inactive the seller told tat he called up verizon and took unlock code and inserted it in phone but m not sure he did ....becoz if he did then how is phone still unactivated so m kinda so confsued...hope some one explains me...

I'm going to assume you are not in the U.S. due to your English. If your local carrier has provided you a SIM card, just plug it in the Droid 3 and see if it works.
If the phone is locked for foreign carrier and requires an unlock by Verizon, then you're screwed because you won't be able to call Verizon to unlock it for you (being that you're not in U.S. and not a Verizon customer).
As for calling Verizon to activate the phone, that's for Verizon customers in the U.S.

i dont have the phone yet my bro will receive in two days.and then he will send me. so how can he check weather its unlocked or not?...the seller told us tat he have put up the unlock code and even has given the unlock code...
but i doubt becoz the phone is not yet activated...the phone is still in shipping my bro will receive it in 2-3 days....
so my questions are
1)what sim card should he use to check there in usa
2)the phone is not activated so is it necessary that my brother activate that phone with his number? or without activation can a phone be used with a gsm service sim card.....
3) and i am confused can a phone be unlocked without phone being activated?

1) Phone will not work on GSM in USA no matter what SIM card you put in. Your brother must really try to unlock it before he sends it over to you since some cannot be unlocked without Verizon providing the code and you may be stuck with a non-unlockable phone (useless). Get your brother purchase unlock code online and try it (by inserting any non-Verizon sim card inside). If phone unlocks you are good to go. If code doesn't work, he either needs to have it activated on a non-new postpaid account that has been in good standing for at least 60 days and request Verizon to provide the unlock code, or to return the phone and try another one.
2) no activation is needed if you are going to use the phone on GSM outside USA
3) phone can be unlocked without being activated with Verizon, but this might be a tough thing to do since Verizon altered intentionally unlock code of some of the handsets.

He should use an international SIM card to check.

I can't tell you if activation is needed. I've had an iPhone 4S (Verizon) unlocked, but it was already activated when I proceeded. Verizon did require me to tell them the phone number for the phone I wanted to unlock, so it might have to be activated.

This seems to be same question as #2.
I called Verizon and told them I wanted to unlock my wife's iPhone 4S for use in Taiwan. They forwarded me to the global department, and the rep told me to hold on the line while he unlocks the phone.
After he said it was unlocked, I tried my wife's sister's international SIM card in the phone. The phone didn't ask for an unlock code, but the SIM card did, since the sister had set a code. She knew the code though, and after putting it in, the SIM was accepted. We won't know if it's for sure working until she brings the phone to Taiwan, but it appears to be working.

I think that goes away if you put in a SIM card.

[Q] Bad esn droid 3 global

hi. if my droid 3 global has a bad esn, can i use it with the verizon gsm sim i have?
thanks

No you cant. The sim card is for global once you travel out the US. If you can get the device sim unlock from Verizon, I would just sell the device to someone International and buy another phone after that. Once a device has a bad ESN, the device is not usable by that carrier until the device is cleared of.

actually, the verizon sim does work in the US. right now, i am on a laptop using it. i can get an unlock code if i wanted to also. and what i am thinking is that only cdma uses ESN. if i use the verizon sim, wouldnt it work anyways? because sim does not use ESN.

You are correct, only CDMA uses ESN. GSM modems uses MEID

Exactly. So can it use the verizon sim instead, and still work?

Wait a second. Lemme get a couple things straight:
1. You have a VZ D3.
2. Your ESN for your D3 has been blacklisted or blocked in some way.
3. You're getting service on your D3 despite your ESN being blocked?
VZ doesn't have a GSM network, so the SIM is completely useless in the states, because you can't use the UMTS radio as VZ has blocked US carriers (unless you've flashed with the Chinese ME883 rom, which updates the radio firmware so you can use it on AT&T / T-mobile (2.5G only). If your ESN is blocked, you shouldn't be getting any service at all.

No, if the ESN of the device isn't working at all, a SIM card isn't going to be much good. All CDMA devices (re: phones, mobile broadband modems) use ESN/MEID to authenticate the device for service, NOT IMSI, which is what the SIM card provides. The D3 won't be able to work even with a valid Verizon SIM because it doesn't use that at all to authenticate. The IMSI/SIM is only used while roaming on GSM networks.
In a nutshell - GSM uses IMSI on SIM card for service. Sticking a Verizon SIM card in will do nothing for the D3 because the ESN/MEID is still bad.

I'm guessing you can only use a non verizon sim card outside of US if you're unlocked, or flash the XT883 rom instead

i think eXecuter means... "GSM models use IMEI", by all means, MEID is just the code of newer generation replacing ESN (since ESN is exhausted)

Trouble getting a data only sim card to work

I have a verizon htc one m7 running a custom rom. I'm currently in Japan and decided to get a data only sim card. Registering on the site was fine, but when I put the sim card in the phone says that it is a non verizon sim. I've put in all the APN info and I think everything should work but it isn't. I've been looking for a solution for quite a while now but with no luck.

You will need to get the device sim unlocked from the carrier.

I just spoke to a VZ rep and they said I didn't need to get it unlocked in order to use it.

If you put in a sim and it tells you it is not a Verizon aim then it is locked and they have no idea what they are talking about. Which I hate to say is not uncommon for customer service people.

Just tell them you need it unlocked to be able to use international SIM cards.

Verizon HTC one comes sim unlocked out of the box. You must change the network type to global. On most stock based ROMs, it is set to CDMA/LTE only by default.
You must also double check that the carrier you are using utilizes the frequencies that the Verizon one supports. Below is the GSM bands the Verizon one supports:
UMTS/HSPA 900/2100MHz,
GSM/GPRS/EDGE 850/900/1800/1900MHz
The verizon one does not support WCDMA or AWS LTE.
