Unless I misunderstand your question, you can use either version of the S4 Active with AT&T prepaid "out of the box". You don't need to unlock anything.

a friend of mine just bought a new s4 active. she was/is on a business plan on her family account. they are no longer going to use att for service. so she is stuck with this phone. she wants to do a prepaid plan with att. is it possible to make a regular service phone a prepaid phone. if so how and someone please point me in the proper direction.

You are going to have to have ATT unlock it

Umm, why? I'm not arguing; I'm just curious, since my experience was different.
I have an "extra" i537 that I got from AT&T when we signed up (signed up 4 lines on contract and got all new Actives when I did, but am using one of my SIMS in a different phone). It was brand new out of the box and, I assume, SIM locked to AT&T. When a friend was visiting from Europe I let him use the i537 while he was here. He walked into AT&T with it, bought a pre-paid SIM of some sort, stuck it in the phone, and started using it just like that. Never had to unlock anything, or at least never told me that he did...

she tried going directly to att and they failed. so i will give it a try when i get my hands on it. thanks for the help people. any additional horror stories or advise would still be greatly appreciated.
thanks again

I just did exactly this for a customer. Just insert the go SIM. No unlock required for gophone

I have a at&t locked active I traded a guy my note 2 for. No unlocking needed for me to use my net10 sim card in it. You shouldn't have to unlock anything to use it on prepaid.

Yes exactly but I thought that was common knowledge of the use of prepaid sim services. Sorry for not specifying.

thanks for all of the help. after att would not give me the code for the phone i went online and found sim-unlock.com and paid for the code. i inserted the straight talk sim card ( its what she ended up going with.) and it didnt ask for a code. but only had 2/3g connection and was only able to make calls and text. so i inserted my verizon card and voila it asked for the code. entered the code and restarted with the new card and i now have 4g and data. thanbs for all of the help

Activating a tmobile n6. Then move to Verizon.

Well would Verizon blacklist or whitelist the I.d. number? My sis Wil buy it then activate it then just give me the phone.
Just worried about Verizon blocking it later on

A T-Mobile sold N6 will most likely not be able to work on VZW. See this thread for more details: http://forum.xda-developers.com/nexus-6/general/cdma-carriers-buying-nexus-6-consider-t2922642

The only sure way it will work is if you already have a nano-SIM. If you currently do not have a nano-SIM, and plan on getting once you get the T-Mobile N6, that is what no one has tested yet.
But droid-life already did the test, the T-Mobile N6 worked with a Verizon nano-SIM just fine.
Best way to do this:
1. Call Verizon and order a nano-SIM over the phone. If they ask for what device, say you just ordered a Droid Turbo from eBay.
2. Upon receiving the SIM and the N6, go to verizonwireless and login. Click on 'activate a device', choose 'device that has never been on verizon', enter your current phones IMEI (not the N6), then the SIM ID off the nano-SIM you just received.. The SIM will now be active, and your current SIM in your phone will deactivate.
3. Insert the nano-SIM into the N6, and you will have a working device.

Can anyone else confirm this? I have a t mobile account and I'm planning on buying it on my line most likely ordering it because they don't have it in store and then giving it to my cousin on his verizon account.

It has been confirmed in a different thread already. The guy got the phone yesterday from T-Mobile. And it worked on his Verizon account, he is currently using it on Verizon, it has LTE and 3g and all that stuff, just like a Verizon phone would. He also tried his friends ATT SIM, and the phone worked as would a ATT phone. Its in a thread in the general section somewhere, good luck finding it.

CDMA unlock Verizon Note 8 for Sprint?

Is there such a thing as CDMA unlocking? Samsung said that it is carrier-locked to Verizon. Verizon said they no longer lock phones. I could not get it activated on Sprint. They do not accept the IMEI.
Is there any way to make it working on Sprint? Please help. Got stuck with a phone that can not be used. Thanks

Verizon phones are all carrier unlocked. I'm using a Verizon Note 8 on T-Mobile right now.
Couple questions:
1. Have you double checked to make sure the IMEI is clean and clear? If its blacklisted on Verizon, it won't work on any US carrier.
2. Do you have a nano SIM from Sprint that's already activated?
3. Have you tried flashing either the unlocked firmwareor the Sprint firmware on it?

Thanks, Mr. Orange645
The phone was bought brand new a month ago from Best Buy , and used on Verizon for a month. Phone paid off and no contract. IMEI should be clean. I did a check on Ting with the IMEI , and it can be used for GSM.
I have two nano sims from Sprint, both activated and un-activated. The problem is that Sprint can not add the IMEI to their system. I called Samsung and gave the IMEI, and was told that it is carrier-locked to Verizon. I wonder whether there is way to do CDMA unlocking.
I did not try to flash unlocked ROM. I think that IMEI on sprint network is the first step.

So you have a nano SIM that's already activated with Sprint? It's in a Sprint phone right now and has service?
If So, put the activated SIM in your Note 8 and see if you have service.
Sprint shouldn't have to activate your phone, just the Sim. That's how you can buy the Unlocked version from Samsung.com and stick your Sprint SIM in it and have service.

Sprint uses CDMA, and have to add the IMEI to their system to make it work. Also tried the activated sim, with no luck.

There is no "CDMA unlocking," it's either carrier unlocked or it's not. And ALL Verizon LTE Devices are Carrier unlocked.

Have you tried simply factory resetting the device first and then booting up for the first time with the activated Sprint sim in.

Maybe try flashing Sprint firmware?

IMEI is hard-coded. For CDMA, it must be added into Sprint systems. Unless GSM, only a SIM is necessary.

Did Sprint not provide some sort of reason/explanation as to why they are unable to add the IMEI? If they can't do it, surely they can tell you why.
CDMA networks are finicky -- Sprint's in particular -- when it comes to bringing over other carrier devices (even ones with compatible hardware). Some good info in here:

I believe someone is giving you false information. You should be able to place an activated SIM card into the phone and start using it. That's how the unlocked Pixel, Pixel XL, Pixel 2, Pixel 2 XL, Galaxy S8, Galaxy S8+, and Note 8 all work. You buy them unlocked and use them on whichever carrier you want, including Sprint. That's how my Nexus 6 worked on Verizon, before I switched to T-Mobile. Verizon also uses CDMA, and they didn't have to add any IMEI into their system. You just put the activated SIM into the phone.
I could take a Verizon SIM and put it into my T-Mobile S8+ right now, and it would activate and get service.
But to answer your original question again, THERE IS NO SUCH THING AS CDMA UNLOCKING. The phone is either carrier unlocked, or its not. And the Verizon Note 8 is 100% carrier unlocked.
I beginning to suspect you bought a Note 8 with a bad IMEI, if you got it used.
EDIT: I MAY BE WRONG (don't tell my wife, she never hears me say that)
After doing some research on Reddit, it looks like others ran into the same issue as you. The unlocked version and the Sprint version will work, but none of the other carrier Note 8s are eligible for BYOD. Which is stupid, since they are all exactly the same hardware.
I'd try this:
Use ODIN to flash either the Unlocked 950U1 firmware, or the Sprint 950U firmware. Then place the Sprint SIM card in the phone to see if it activates upon start up. If it doesn't then you may be hosed. If that's the case, sign up for T-Mobile. LOL.

Thanks all for the useful information and help. The error they encountered is that they could not load the ESN to the Sprint PLBL database. They got error like incompatible, or unsupported device etc.

Sprint will not add other carries phone to their system. If IMEI is from Verizon it will never work with active or inactive SIM. Only way if it was factory unlocked phone bought from Samsung.

Did anyone find a solution to this? Moved to Sprint BYOD two days ago with my Verizon note8 and it won't work. The phone keeps asking for a Verizon since. I am at second Sprint repair center as I type this. Please tell me it can be fixed. Thanks.

I am in the same boat, Paid off my wife's Iphone7+ and my Note 8 with Verizon and then tried to BYOD with sprint and they are unable to activate. Verizon informed me that their devices are 100% not locked and Sprint has no clue.

You could try other carriers like straightalk or tmobile maybe even metro pcs but it will not work with sprint. They are a pain and don't allow other carrier phones on their network.

I purchased a Verizon Note 8 , which was paid off and unlocked. Successfully activated on Sprint using my existing Active Sprint sim card.
Everything looks good, just one major issue, I am stuck with 3G internet. Still not able to get 4G LTE on Sprint.

you need to enter sprints apn bro then you will have 4G.

I have the reverse issue. I have the opportunity to get a good deal on a Sprint Note 8, but I want to use it on Verizon. Assuming the device is not blacklisted, would there be any issue with this? Buying a sprint-branded phone and using it on Verizon's CDMA network? Are all the bands the same? I get 3 checkmarks on willmyphonework.com (but they didn't have the Note 8 yet, just the Note 7)

AT&T Note 8 to Verizon

I'm having an issues with a Note I just got. I'm looking to switch it from AT&T to Verizon.
I went through AT&T and got the unlock code, put in the Verizon sim and entered the code. After that I went to switch over the phone on Verizon, but they said that my device was not compatible with the Verizon network.
From what I'm aware of, unlocking the phone would work. Has anyone else had an issue with this? Or do I have to go through trying to flash a Verizon firmware?
Model: SM-N950U
Baseband: N950USQU2BQJA
Android 7.11

As long as it's unlocked the device will work on Verizon, but as the phone originated from AT&T, Verizon recognizes the IMEI as not compatible. If you have another verizon device you can activate that one and do a SIM swap.
You may be able to flash the Verizon firmware over, but Verizon still won't activate it on it's own as the IMEI will remain the same. You may be able to get them to add it to the approved list, but that's up to them.

So if I were to swap over this phone from another one (an S7 that is currently on Verizon to the Note 8), it should work after being unlocked?

Yup. Pop in your activated VZW SIM card. I would also recommend flashing either the VZWfirmware, or the unlocked 950U1 firmware. ,

Could you link me for getting that firmware? I got in contact with Verizon and they said...
I am showing the information as follows: users must have software version of NRD90M.G950USQU2BQK5 or NRD90M.G955USQU2BQK5 before they disconnect their service with the prior carriers (AT&T, T-MO, etc). It also goes on to say that Samsung is working on a workaround so that devices do not have an activation issue but there is no specific date or information that has been resolved.
Would the firmware update fix that?

Check the carrier switching thread for answers. If you don't find answers by searchingfirst, then I would suggest posting your question there.
As far as links for the firmware, check sammobile.com or updato.com.

The current active Verizon sim you have. Place it in the Verizon S7 and give the S7 imei to Verizon to get service. Them once your S7 is fully operable remove sim and put it inside the unlocked note 8.

This is partly true...At&t is GSM based network and Verizon is CDMA. Not shure on which frequency at&t phones can woark on Verizon network, is it only 4G or?!

How long did it take them to add the IMEI? They told me 72 hours and today would be 72. I guess they are taking their sweet time....

Switch to SIM card?

I have an at&t version that is off lease. The phone was paid for so I kept it and basically been using it as a mini tablet on my home WiFi for the last year.. it still works fine
Is there anything I can do to make it work off a Sim card?

Take any SIM from a phone you already have active, place it in the Nexus and Viola!!!

If you want to use the phone on a carrier other than AT&T your going to need to unlock the phone first. You can request an unlock code from AT&T here.

Thanks, but I have since found it was with Sprint.
Thanks for your help. I've sense discovered it was with Sprint. You wouldn't happen to have a link for them would you? TIA

If it is on Sprint it should already be unlocked. AT&T was the only carrier to offer the Nexus 6 and therefore it was the only locked version.

That's odd. This is a Nexus 6 and it was on Sprint. It hasn't been active for over a year but the carrier still says Sprint.
Will the internal antenna allow it to work on a Tracphone (generic prepaid Verizon network) sim?

I'm not sure about it working on Tracphone but my gut feeling is that it will. The Nexus 6 worked on Verizon so that shouldn't be a problem but I'm not sure if the APN settings for Tracphone will be there or if you will have to manually create a new APN for them.

So, the phone will "remember" its last carrier until you pop in a SIM. Should work just fine.
