[Q] Changing CDMA - Thunderbolt Q&A, Help & Troubleshooting

I recently messed up my HTC Incredible and thinking about getting this phone off ebay/craigslist. My question is, is it easy to change the CDMA from phone to phone? I wasn't able to really see any instructions online specifically for these phones. Also, am I obligated to get a 4G enabled on the phone from Verizon?
Thanks

Yes and yes.

Thanks - are there any tutorials on changing CDMAs? I'm having a hard time finding anything through Google.

What exactly do you mean by "changing CDMA's?" Do you mean switching the phones out on your line?

Yeah - I want to switch my line from the old incredible into a new phone. Should I just go to Verizon and have them program the new phone?

CDMA != GSM
I believe you might be confusing swapping out a SIM card for transferring your number to another phone. You can get the phone off of eBay or CL, go to your local VZW store, and just have them transfer your number to your new phone. I believe the TB should come with the 4G LTE SIM card (has nothing to do with a GSM SIM card). If not I'm sure when you go to VZW to activate the phone that they will give you one there.

I'd recommend going to Verizon because you need to get a SIM card to activate the device anyway. Head over there and tell them that you're switching your DInc out for the Thunderbolt and that you need a SIM for it. They can activate it on the spot for you.
Even if he did get a SIM card with it, that SIM is not tied to his number. I'd still suggest going to Verizon and letting them handle the situation.

As someone who just purchased a TB this way I can confirm: just walk into a corporate Vzw store and they'll give you a new sim (free) and activate your phone.
Kind of annoying having a sim like that, we used to be able to change equipment on he fly through Vzw.com or over the phone.

VZW's 4G phones still use ESN numbers too. The sim is just to get access to the 4G network. You will want to make sure the phone you are buying has a clean ESN number. If VZW has it flagged as stolen or something, they wont activate the phone for you and there's nothing you can do.

can you switch between phones when you want

my thunderbolt similar just went bad when switching between my thunderbolt and incredible. I did not hit *228 on my thunderbolt which makes your similar bad. the tech support Guy said once you activate another phone, the similar goes bad. is this true? if not l, what's the easiest method to do this?

My guess is he means Sim [card] and it's autocorrecting to similar
To OP: You're stuck, at least as it comes to your 'bolt, for the time being. You CAN activate another phone on your plan (like your inc) but the only phone on VZW that uses a sim right now is the 'bolt, so you will have to take it in and get a new SIM card, or have VZW send you one.
I don't have personal experience, as I haven't switched back from the 'bolt to a non-LTE phone yet.
So with the new SIM card, it is my understanding there is no need for activation anymore, correct? I had to have my first 'bolt replaced due to mic issue, and when I popped the SIM in the new phone, it just worked. I have never activated it. Any info if this is the case with all phones that will have a SIM. If it is I am so totally getting an Xperia play, if it has a SIM slot.

Right - the SIMs, as they stand, are interchangeable between 'bolts. No more activation or other things, but it won't work with just any phone - it has to be a Verizon network phone because the tech for 4G is different (it's not like when people could swap sims between ATT and TMo phones) - so, right now, since the Thunderbolt is the only 4G phone on Verizon, swapping SIMs will only work with other Thunderbolts
VZW explained it to me this way .... when going from a 4G LTE device to another 4G LTE device there is no activating anymore, you simply drop in your sim card. But, if you activate a non 4G LTE phone on your account that will deactivate your sim card and will require you to return to the store for a new sim card. This was in response to me asking them if I could switch between my Droid and Bolt.
For once VZW was very helpful in store. I normally don't go to the brick and mortars but being new to 4G I had questions I needed answerd.
The SIM doesn't get "destroyed" and can be re-used.. but... you have to call Customer Service for them to enter the SIM number...
here is what I did...
When I first got my TB, VZW was having network issues, and it took well over an hour for my "activate device" request to "clear the switch" and the TB to become active.
Having intermittent data issues over the next week, I decided to swap back to my INC, wait, and later return to the TB... I thought maybe due to the network issues, the TB didn't get all its programming info "over the air" or something.
When trying to return to the TB via the Activate Device link on the My Account web site, after entering the MEID/IMEI... I got prompted about needing a SIM... so I enter the SIM number and got...
"The SIM associated with the SIM ID you entered cannot be activated at this time. Please contact Customer Service at 800-922-0204 for assistance."
CS rep couldn't help... she had me on hold while she got Tech Support...
They had to manually add the SIM number back on the account.
Moral of the story... if you activate an LTE device and remove it from your account to use a 3G device.. you'll have to call back in and manually switch devices if you want to go back to using the 4G device.

The real reason you can't put your SIM in an ATT or Tmo phone would be the tech. ATT and Tmo use the GSM/UMTS/HSPA (3GPP) family for "2G"/"3G"/"3.5G" where as Verizon uses CDMAone/CDMA2000/EVDO (3GPP2). SIM cards are only on Verizon now that they're using LTE which is the next step in the 3GPP family but not quite 4G. Any phone made for AT&T or Tmobile is a "GSM" phone using the 3GPP family radios which are incompatible with Verizon's 3GPP2 network (towers). On top of that, they all use different frequencies. That's why unlocked iPhones can only use "2G" on Tmobile.

Were they able to re-add your sim to the account? I had a Thunderbolt which I traded for another phone, and switched to a couple of 3G phones in the interim. The Verizon store person told me my sim would be good for 90 days if I got another Thunderbolt. So I did, popped in the sim, and called support to switch over from my Fascinate to the new Thunderbolt. They got tech support on the line, and I was told that switching to a 3G device from a 4G device causes the 4G sim to be "retired" and that I needed to have them send me one, or go pick up one at the store. So the story was different from what happened to KidJoe and I wonder what your experience was.
A couple possible reasons why my situation was different: It was not the same Thunderbolt the sim was originally in. Also it's possible in playing around with the new Thunderbolt, I may have done a *228 just to see what would happen. Someone else suggested that would tank the sim.
I plan to go the store tomorrow and see if they can resuscitate my old sim, or if they give me a new one.
I had activated my thunderbolt when I got it with no problems. I decided to switch back to my incredible for a day and the sim was deactivated. Vzw gave me the run around between going to the store and calling customer service for a few days then they finally said they would have to send me a new sim because as soon as I switched to the inc my sim was "retired".

Yes. They were.
I did my switches only a few hours apart... (i.e. switched to INC, waited an hour, switched back to TB). And used the same phone and SIM. Not sure if that had anything to do with it.
There obviously is an inconsistency in VZW's system somewhere... the message you get when using "Activate Phone" on the my account web page to switch away from the TB says the SIM will be deactivated after 90days. But its being deactivated IMMEDIATELY. Either that message needs to be changed, or VZW's system isn't set up correctly.

LTE sim cards?

Ok, so I'm totally used to CDMA, obviously, but I've lived abroad and appreciated the beauty of just swapping SIM cards in when you're in a new country.
Is it possible to just swap SIM cards like GSM cards, or do you still have to call Verizon to activate? The reason I ask is, my father and I were going to swap Thunderbolts, but I didn't have time to call Verizon and do the ESN swap thing. Could we just have swapped SIM cards?
SIm card
SIM cards are for GSM technologies.... Verizon LTE is a GSM tech... And yes thats the theory, with Verizon announcing some day you will be able to use other networks LTE SIM cards in VZW phones. Sim card in your fathers phone gives you access to his google account and contacts.. unless you have transferred all google contacts to your SIM card.
It will only work with the sim you are given for the TB.

Got it. So the SIM is tied to the ESN somehow? Either way, they don't work like GSM sims.
they would most likely if the phone were entirely gsm, but since it's not. Like if you ruin the one you have, the only way to get a new one is directly from verizon and they can only be activated for the phone they are first put into.
dude no one here knows what they are talking about. if you swap sims with your dads phone then it should work fine. the phones will activiate with the respective phone number tied to your sim card. that is how you activate a replacement device as well. i just took my sim from my old phone and put it in the new phone and that is it. works JUST like GSM

If that was true, I wouldnt have to replace my SIM card both of the times Ive sent my phone in for repairs. My service is still on, just switched to a different phone. The verizon rep I spoke with yesterday(One of the few that actually know what she was talking about) confirmed that the moment that a phone gets disconnected the sim card gets retired. I dont know why, and I dont understand it, but thats the way VZW is rolling with it for now. As long as I dont have to pay for it, IDC. lol.

that must be because whoever is disconnecting the phone is killing the sim also for some reason. i have used the same SIM card in 2 thunderbolts and a samsung charge.

That's just it. That rep doesn't know what they're talking about. If you get a replacement TB, nothing should be changed on the account - no phone gets "disconnected." You simply move the SIM to the new phone. Sounds like that rep thinks it should be like a CDMA phone, where the account is changed to reflect that the phone's ESN has been changed when swapping phones.

Did you activate an old phone while waiting for repairs? That's really the only way your SIM would be deactivated.

I did. Im still unsure of why they retire my sim though. All in order to send me another one that will sit here till my phone gets back. Why not just put it on hold or put it on temporary hold?
Sim cards work in any phone that will take them.
Just to put this one to bed--they work just like GSM SIM cards. I swapped my SIM between another Thunderbolt and a Charge, and it worked perfectly every single time.

UNLOCKING for use aboard

Hi everyone,
I see that the Droid Incredible 4g does support sim cards, I was wondering is it microSIM like the IPHONE or regular SIM. Also, since Verizon doesn't give out unlock codes, is there anyway to get my phone unlocked myself so I can use a prepaid sim when i travel abroad? Thanks, any hlep would be appreciated!

It's microSIM. Don't know about unlocking it.
I've heard mixed news on the unlocking process. I've heard if you pressure them for the unlock code they will give it to you. (tell them you are going out of country etc). I've also heard that they don't give them out. (which I don't believe because people have received them before). Other than that, there are companies that charge you $15 and they'll send you the unlock code.

I got off the phone with Verizon Global Support and apparently the DI4G is not locked and you are free to use a 3rd party sim card. Same is true for Droid RAZR and MAXX.. can someone confirm this? I do not actually have the handset.
I read the same thing but with the question posted here I figured it wasn't true.
From the GSM thread in this section:
Brooose said:
I was curious because I heard that the Droid Incredible 4G has a GSM radio in it so I did an experiment. I used a T-mobile micro SIM. I used the 4GLTE switch app for the Thunderbolt to access the hidden menu and I changed the radio mode to one that included GSM/W-CDMA. I popped in my T-mobile SIM and, presto, I got a T-mobile signal. I tested and I was able to make and receive calls and text messages. I had to manually set the APN for data to epc.tmobile.com and now I have EDGE data. I am sure an AT&T Sim will get HSPA+. The GSM appears unlocked now but hard to access. I am afraid, however, that once Verizon releases the update to make GSM roaming available, that it will be locked. Anyway, for now, you can pop in a GSM SIM and use your phone native.

VZW has unlocked the majority of there 4gLTE smart phones. It is a new thing they just started doing to get a bigger hold on the global market that att has had for the longest time. So if you have a VZW 4g LTE phone and you are planning on going out of country all you have to do is call customer care, and ask them about the support and they will set you up with either a global SIM or you could use a prepaid SIM purchased in the country you are traveling to. I am a customer service rep at a local call center in Utah, we just had training on this subject last month.

They're not locked, but they're not "officially" globally capable either. I imagine in their global updates they will be locked to Verizon's official roaming carriers and you'll have to request an unlock code

Not sure how anyone can help you here. If you're not a Verizon customer then Verizon can't unlock them for you. Not sure what their policy is on unlocking 3g phones either.
Update: Pulled this from the web.
Verizon has confirmed (here and here) they WILL unlock the SIM on the iPhone 4S, allowing for use of local SIM cards while traveling abroad (no word yet on whether this will allow for use on AT&T and T-Mobile.) This is different than the jailbreak unlocking method; SIM unlocking through Verizon is permanent and will not affect your warranty in any way.
1. Meet the following requirements:
* Must be a Verizon Wireless customer.
* The iPhone 4S being unlocked must be active on a Verizon Wireless line of service.
* The line of service must be active at least 60 days.
* The line of service must be in good standing for the past 60 days.
* Only one SIM Unlock per line every 10 months.
If you don't meet one or more of the above requirements, call anyway. You may still get lucky.
2. Insert a foreign SIM into the SIM card slot on the side of your phone (only required to confirm that the unlock is successful.)
3. Call 1-800-711-8300 (Verizon Global Support) and ask the representative for a SIM unlock. Occassionally a representative may not know exactly what you are referring to; make sure you are not transferred to a different department. You are in the right place. Explain that they should have a walkthrough on how to do this, and that it allows for the use of local, non-Verizon SIM cards while traveling abroad.
4. Get confirmation from the rep that the unlock has been applied to your account, then check your phone to make sure it recognizes your SIM and can connect (if successful it will roam on AT&T, assuming you are calling from the USA.) You will NOT see an unlock confirmation in iTunes as that is for a factory-applied unlock only.
5. Enjoy your new unlocked iPhone 4S!

The iPhone 4s I have got clean ESN. Someone has to put it on his line and call up Verizon to unlock the device for international use. Need to tell them that he wants to use it with a local sim card of the country where he is travelling to. All the time, the device is resting here, powered off. So that there are no charges incurred to the person who is doing this favour to me.

Would be really hit and miss for someone here to do that. The 4S is a 3g phone, activating it on our lines would require someone to go in store and get a sim swap. And even then, with the rules posted above, they probably still wouldn't do it.

Nope you don't need a sim swap. Just need to put the MEID of my device on your line. Once you do that my device gets 'active' on your line and then a call need to be made to VZW international dept or a live chat can be done, telling them to unlock the device for international use.
While you do the device swap on your line they may ask you to put the data plan on iPhone 4s which is mandatory to have. Ofcourse, I'll be more than happy to pay any expense.

Thats understood. But putting a 3g device on your line, deactivates the 4g LTE card. They cannot be reactivated, you have to go in store to get a new LTE card.

I have an HTC Rezound, and I'd heard it was unlocked.
I'm abroad in the UK (Scotland) but when I put in an international sim card it says the sim card is unrecognized, and I can't get any signal but I can turn on mobile network I just can't access it (no signal). I messed with the APNs (using my network in the UKs suggested settings) but I can't seem to get it to function.
I know that the phone itself says it only offers CDMA and LTE but I was wondering if there was a sneaky way to get to the GSM capabilities of the phone that aren't in the menu.
I tried
*#*#4636*#*#
and when I hit the final hash tag the phone just acts like I just opened the dialer app

I don't know about the Rezound, but on our phone, since the latest update, you could change the setting under Settings -> Call -> Preferred Network to Global. There's also an option for GSM/UMTS.

Try something like SWITCHIT - 4G LTE TOGGLE -- it fires a different intent that gets you to the magic phone info page that *#*#4636*#*# is supposed to send you to.
On my Inc 4G, this lets me use AT&T's network in the US (with an appropriate sim). I haven't tried it abroad.
I tried it abroad. No restrictions. 2.17.605.2.710RD is needed

Confused, I have Samsung galaxy Axiom and....

it is from us cellular if you ask me its the s3 mini anyways itsa cdma phone that has a sim slot which has a card in it for us ceullar. now im confused the phone specs say its cdma only but with a sim card that makes me t hink its gsm global(locked to any us gsm providers im sure) and cdma so I would assume it will work with say cricket wireless.
I am leaving u ceulluar and would like to use the phone with c ricket wireless and being its a cdma phone im surei could it is just that sim card confused me.
I know on phone in past cricket can take your imei i think it is and use a tool over the phone to convert it to propperly work on their network.
So basically anyone know if this phone can be used with cricket? is it locked? do I ahve to flash it. if the gsm part is locked that wont matter since i will only be ising the cdma part. here is the link to the phone on us cellular

Edited: The sim card has your programing for CDMA & 4g/LTE access. Just took mine out and it has zero service without it. I would guess as long as you put it in another compatible phone you would get service.
Hoping someone will figure out a simple rooting method, but doesn't appear there is a lot of interest yet.

Thanks but nah not what I was wanting, i wanted to be able to use the phone on cricket but since they dont use sim cards since their phones are cdma was why I was confused that this one has a card since usually only GSM phones use those. so im guessing I wont be able to use it on their network if they added it..I know they can convert certain imei's over the phone with a tool they ahve with cricket support but have not tried that yet.

So, just wondering, would the Samsung Axiom work on T-Mobile or AT&T ?
yes and no
The R830 by U.S cellular is a CDMA phone. now ah days having a sim card slot does not symply mean its GSM ....TMobile....GSM ALL DAY. ATT GSM all day. Vzw,sprint, uscellular...CDMA. the Sim card in question is a 4glite. it controls the 4g side and basically activates the phone upon new activation. the question is: WELL THIS PHONE WORK ON CRICKET? Answer...yes...I put one on Pageplus by just activatiing the imei and then OTA...but I'm having trouble with the DAta side... cant get data or MMS (picture messaging) to work..talk and texts works fine.....Now im on to figuring out how to get this thing into DiagMode without rooting it Oh yeah.....try activating your Imei on cricket and then star code it. . if it asks you to press 1 or 2 but you dont see a keyboard,....thats okay...just let the lady run her mouth until the music starts playing....when its done the phone will restart and you'll have talk and text

No, your phone will not work on either. The sim slot in question is for 4glte, all 4g phones will have this sim slot. A GSM sim will not provide any functionality at all.

Was anyone got success in enabling the data ???

Does anyone know if the imei number on a sprint htc one will activate on at&t ?

Does anyone know if the imei number on a sprint htc one will activate on at&t ? Or will at&t not acknowledge an imei from a sprint htc one ? As a sprint htc one has both an esn and an imei number. Just curious if at&t would allow the sprint imei number on their system ?
No it will not. Sprint is an entirely different beast of a phone. Plus, from what I understand, they don't possess the needed tools to unlock the phone even if it could be put on AT&T's cell bands

It's not a question about working on at&t because it's documented all over the net that it will, as you get talk, text and HSPA 4g data you just don't have the ability to receive LTE data. The sprint HTC one does have a imei number my question was will at&t accept that sprint imei number or does it require a different imei number one from an at&t phone ?
In that case, if it's documented all over, then your answer should be in there. Honestly, AT&T's main service relies on the SIM card, not the IMEI like Sprint or Verizon, so if the phone reads the SIM, you should be good to go. You just need to sim unlock the phone, which is the biggest issue you're going to have. Everything I read on the net is that Sprint does not currently have a SIM unlock mech built in, see http://bit.ly/RLoHko

Yes it does but if they do not distinguish it as a good imei for them then in a matter of time they may deactivate the SIM counting it as a bad imei because it's not one known to them. I have done imei tests to see if they show it's a good imei and they come up unknown like they at&t don't recognize the sprint imei number so it's more that just throwing an at&t SIM in and thinking it will just work forever because they may turn it off because they don't recognize the sprint imei number. There are methods on the net to unlock the sprint SIM there is even an app on play store for unlocking the SIM on a sprint HTC one.
I don't know what to tell you then. I've used a number of non-AT&T phones on their network, from the international S3, to unknown knockoffs, with out an issue. Honestly, sometimes you have to be the sacrificial lamb and try it out. Or, you call up AT&T to ask them, and let them know your intention, alot of times, they'll be really helpful. All in all, just my 2-cents

We have gotten off topic, this was in no way asking if it can be done, because it's documented that it can be. it's just not talked about weather the sprint imei number will work. Its about weather at&t will accept the sprint imei number.
Please only respond to this posting if you have personally used a sprint HTC one on at&t or if you have direct knowledge of someone that has. This post is not in any way asking if it can be done because it can as there are videos on the net of sprint HTC one phones on the at&t service. So please don't post trying to say it can't be done.

People with the Sprint M7 had no issues using AT&T or T-Mobile, so I don't see why that wouldn't be the case for the Sprint M8. If you're SIM-unlocked and your IMEI isn't bad (like those on phones reported stolen), I'm not sure what the problem would be.

One might think that but on a test of my sprint imei they done recognize my imei number that is why I am asking for someone that has done it. I do not want to switch to straight talk at&t and have problems because right now I am flashed to a Verizon mvno but only get 3g which I had the flash done professionally and if I just try and have problems I will have messed up my flash as the data passwords would probably need to be programmed once again and the whole time my phone would be down. So I would like to have all my ducks in a row. Verizon 3g just totally blows at&t's HSPA is way better faster 3, 4 or 5 times faster or more. And I hate Verizon with a passion they are the worst company in the world they think they don't need to complete like they think they own the market and they deserve more money than anyone else. I wish they would go out of business for being such blood suckers.
CDMA device on GSM network? Wtf?

Yes it's called a world phone they have made them for many yeas even the HTC rezound was supposed to have been a world phone. So they could be housed internationally ie most of the world uses gsm.

What do you mean "on a test of my sprint imei they don't recognize my imei number"? You called AT&T and asked them to check it? They might not recognize it because it wasn't an AT&T phone to begin with.
I would flash back to Sprint, perform a SIM-unlock then pop in an AT&T pre-paid SIM. If all else fails, just flash back to the Verizon MVNO.

No on an imei check web site it was like the imei number was not recognized. If I call at&t they will ask what kind of phone it is and if I say sprint htc one they are going to say no they cant activate sprint phones on their network.
I dont need to flash back to sprint that would not make any difference, now yes I might have to unlock the sim, but my post was not asking about how to do it all because I know all that.
My question on this posting was will at&t accept the sprint imei number, and I dont want to screw up my straight talk verizon flash to find out because if at&t does not accept it then my flash would be messed up and I would have to pay the guy again to re do my data passwords again and he is very busy and can take a bit, but in the meanwhile my phone service would be off.
So just trying it blind is not an option because it may cost me money and time with my phone service being off.
Possible solution
On att's network the SIM card is all that you need to get service up and running, the IMEI on the account can actually be wrong and your service can still be working. You can drop by a store and have them issue you a new SIM card and either let them activate it or call customer service and give them the ICCID. It doesn't answer your question but given the phone will accept the SIM card and the antenna can communicate on the carriers bands you should be fine.

No the imei number makes all the difference in the world if they dont recognize it they may turn it off like a blacklisted imei. Its all about at&t accepting the sprint imei number if they chose not to you could put 100 sim cards in and it wont matter because if they as in their system does not like the sprint imei then they will lock the sim card out everytime no matter how many sims you use. Its not about the phones capabilities its about at&T allowing the sprint imei number on their network.
Problem solved I tried my sprint imei number on the straight talk web site and it shows good for gsm straight talk at&t service. So I will be buying my activation kit at walmart today and I will be getting gsm straight talk at&t service unlimited talk text and data for $45 a month and it includes LTE data even though my sprint phone wont get LTE still at&t HSPA is still a lot faster than lousy verizion 3g data, and unlimited data through them is a 3 gb a month cap and if you go over you just get throttled oh well, which I never use that much data anyway.
Question. Did you pay full retail?
If so why didn't you just buy the developer edition if you going to use it on GSM.
Or sell your Sprint version and just have to add maybe $150 or more for a unlocked m8
