Can CDMA phones (such as for verizon) be activated, then SIM card transferred to another phone then activate the phone again with a different SIM from a different carrier or does the ESN for the physical phone get registered to the carrier and will only work with that carrier's SIM?
Basically, I want to activate a BYOD phone for Xfinity that they won't activate because they don't support it but I know the phone will work so I was going to buy a used Samsung S8, activate the SIM, transfer to the other phone then resell the S8.

You might be able to do part of that. If you use a Verizon device to activate a SIM, in theory, you could transfer the SIM to a different device to activate that device on your Verizon account. But you would not be able to activate the Verizon device with a SIM from another carrier unless the Verizon device has been carrier unlocked, otherwise, it is locked to Verizon only and will only work with a Verizon SIM on the Verizon network.
To do what you are doing, you could get an unlocked phone that is supported by Xfinity, then activate that device with a Xfinity SIM then put the SIM from that device in the device that you are trying to activate. After you're set, sell the dummy device that you used to activate the Xfinity account/service/SIM.

I unlocked my MyTouch 4g (Glacier) and I want to use my Verizon sim card in it but it does not detect Verizon in the network operators. How do I get verizon on there? Is it possible? I thought unlocking it would allow me to do this.

Verizon does not use 'SIM' cards
as 'SIM' cards are used for GSM networks and Verizon is a CDMA provider

I did google this extensively. The phone that I have here is on the verizon network and has a sim card. Why would I make that up?

Verizon is a CDMA network. The SIM card is there because the phone you have also has a GSM radio for traveling overseas. However, just because it says "Verizon" on the SIM card doesn't mean your phone connects to Verizon when you roam. It's actually connecting to Vodafone when you're roaming in most countries. That's what the SIM card slot is for. Now if you unlocked that phone, you could use it on T-Mobile or AT&T if you set it to GSM Mode.
That Verizon phone will work in the US and Canada whether or not that SIM card is in there. It's impossible to get a GSM phone (your MyTouch 4G) to work on a CDMA network (Verizon).

Thank you for the real explanation and not being a jerk about it, as I did not know this.
It sucks that I cant use it but now I know.
I'm moving to straight talk soon, and on their website when you choose a sim card you can pick either an att sim or a sim for unlocked phones. What is the difference. I thought all unlocked phones work on att and vice versa.

Since you never got an answer just choose the AT&T SIM, that way the phone doesn't need to be unlocked if you are using a normal AT&T device.
So any overseas unlocked device will work on ATT? Like an international hox and sgs3?
I am unfamiliar with StraightTalk and what it is, but generally an AT&T sim card only works on AT&T and an unlocked phone works with any sim card ready carrier, which would probably also include AT&T. I think you then need to go get the sim card from the carrier, or at least have it activated by them.
I just opened a brand new (not activated) Verizon SMG920V. I thought these phones were unlocked for international use.
When I put a Rogers Canada SIM I get the "Non Verizon SIM, Activation Required" message.
The only options given are to use WiFi and to Emergency Calls.
What should I do to use this phone with a foreign carrier?
It unlocked for GSM. If your frequency's are supported put it in Roaming mode and the right APN in, it should work.
Hello,
I have called Sprint many times, after they keep telling me it is unlocked domestically and internationally, I finally gave up. The phone simply says to contact sprint to unlock. I have no idea what to do. When I press UCCI Unlock it gives me an internal error(407). I tried flashing unlocked firmware (U1) But it does not work on that either. Tried booting up with T-Mobile sim inside, still same result. What to do?
Please help!
Is Sprint GSM? I thought it was CDMA.
T-Mobile is GSM.
What is the message your phone displays when inserting the T-Mobile SIM card?
As you know, Sprint is a CDMA network and T-Mobile is a GSM network, but the S8 supports both types. but you need to make sure the SIMs are both activated and the phone doesn't asking for an unlocking code.
Also, check if your phone's IMEI is clean in sprint database http://imeipro.info/sprint_imei_check.html
I purchased the India international version of the Nex 8GB 128GB. Sprint will not add the IMEI to their database so the phone will never be able to work with them. When a sim card is inserted you can manually select the sprint network. It will show full 4G LTE and then will kick you from the network since the device is not activated through them. It will just keep trying to connect with no luck. I haven't seen other threads about the phone being activated on Sprint. It does have the LTE Bands to connect but Sprint will not allow the device on their network as they don't support international phones.
what about their voice cdma

It will not work on sprint at all because their system does not support adding the IMEI and so it will never be able to activate and use any of their network.

you are correct
Solution: switch to another carrier.
