[Q] Using Vibrant on Sprint - Vibrant Q&A, Help & Troubleshooting

I did a search and could not find the answer..
Here's my question:
Would I be able to use the Vibrant on Sprint's Network? Would I be able to utilize Sprints 3G, HSPA, HSPA+(not sure if Sprint has this), and 4G network?
I currently have T-mobile and thinking about switching over.
Thanks

Sprint is CDMA, doesn't use a Sim Card
TMobile is GSM, does use a Sim Card
You may unlock your Vibrant and use it on AT&T but not Sprint

Thanks for the speedy response!

It sure does.
Can we swap the SIM card between phones without activation? If yes, I will be VZ customer soon.

as long as the other device is an LTE device and is certified to work on the VZW network then yes

Isn't it LTE just for data, what about voice?

What difference does it make, it is not like they charge $35 everytime you activate new device.
My understanding is that LTE is just for data and will be that way for years and for the voice you'll still need to activate the phone (cdma radio).
would swapping the sim work for traveling outside of the country? for use on vacation is why i'm inquiring.
don't think so as it doesn't actually have the GSM radio needed to support it. You can roam in one of the few countries that offer CDMA though.

Nope. I think you are confusing LTE with GSM. My solution for calling the states when abroad is WIFI calling with Google voice and Sipdroid. If you need to use the phone as a GSM you'll need a GSM capable phone. Verizon does have few global/world phones with gsm radios but not very good choices except maybe the coming-soon DINC2 but it wont be 4g I think.

The SIM is only for the LTE radio. It only supports data, not voice. And it only supports the 700 mHz band. As far as I know, the US is the only country using that band. And it's most likely locked to Verizon. So, lots of obstacles to using it overseas.
The sim stores all your information on it...3g 4g 1x..without the sim you can only makr emergency calls. So the sim stored more than just the 4g information for your phone to work.
Yep VZW is using a CSIM application by storing all your CDMA credentials also on the SIM card. Think of GSM but the 1X voice protocol is CDMA.

In other words, probably if you go to a country that has a CDMA network that supports RUIM cards (SIM cards for CDMA), you should be able to pop it in and use it like any GSM customer can with their phones on any GSM network.
As far as I know, only India, Japan, and China have the RUIM support implemented.
When the bionic comes out you can just switch your sim card to it and go.

Oh, too bad. I am a phoneholic and change phone very often (sometimes once a month).

short answer: no
long answer: read the other posts in the thunderbolt forums for similar questions.
Side note: there are some verizon phones that are "world phones" that have sim cards in them. The droid 2 I think some of the blackberries do. I would return and get one if you can.

different type of SIM card. Thunderbolt has one for 4g only. Verizon uses CDMA for 3g and LTE for 4g, and probably some other band for voice. ATT uses GSM for 3g and HSPA+ for 4g. So they are completely NOT compatible.
ATT will be eventually going to LTE, but they could be dicks about it and choose a different frequency of LTE than verizon to prevent people from switching networks (since there's more than one to pick from), thus making it incompatible still.
Currently, all voice is CDMA on verizon still and data is CDMA as mentioned if it's 3g and LTE if it's 4g (which is what the sim card uses as it is the next incarnation of GSM). Next year they will be transitioning to voice over LTE.

Straighttalk on Vibrant!! Diff b/w Straighttalk Tmobile sim & AT&T sim?

I am thinking of switching to Straightalk $45 unlimited everything plan for my Vibrant (unlocked and rooted). I am wondering if anyone here is using Straightalk on Vibrant. I hear people talking about
‘Straight talk Tmobile sim’ and
‘Straighttalk AT&T sim’.
This might be a dumb questions but What is the difference between the two? Do I have to request a ‘Straight talk Tmobile sim’ in order for it to work with my Vibrant. Will I get 3G speeds and not edge? I also hear that MMS don’t work but I m not too concerned with those since I don’t use many.
I would love to hear from any straighttalk users on Vibrant!!
Thanks
Straight talk is an MVNO (mobile virtual network operator). They use different carriers. You need to specify which carrier sim you need per your device in order to get 3g data speeds.

So I need to tell them I need Tmobile compatible sim for me to get 3g on my vibrant?
You can get either t-mobile or at&t sim. They both will get 3g on vibrant. Vibrant has att 3g combatiable bands. Go with the compant that provides better coverage in your area.

Thanks. Its good to know that Vibrant gets 3g on either ST ATT & ST Tmobile sim.
I would double check that AT&T is using bands for 3g service that are compatible with vibrant. I know that the AT&T captivate doesnt work on T-Mobile 3g service.
What you don't know could fill a book.

[Q] Will ATT One work on Sprint network?

Long story short. Will a HTC One AT&T work on the Sprint network? Google has Sprint to AT&T, but not the other way around. I read about different bands and 4G and all that, but simple yes or no, will it work and what will work...

Sprint Phones do not use a SIM card. So any phone that uses a SIM card will not work on the Sprint network. The One uses a SIM card.

Can I use a verizon sim card on my at&t s6?

I've read somewhere that the two LTE networks are compatible, but I cannot get the Verizon sim card to work on an AT&T phone.

This happens because Verizon is a cdma network, at&t is a gsm one, verizon uses lte only for data, and the at&t phone doesn't have cdma hardware
