Sprint LS970 use on AT&T - Sprint LG Optimus G

I am pretty sure this was asked before but either the search in here nor in Google gave me a proper answer. Is is possible to make this phone work on AT&T? It uses Sim cards and is able to be used in Europe. But I also know American carriers like to block the Simcard use on those phones within the USA. So is it possible to use this phone on AT&T?

The sprint simcard is cdma for 3g while att is gsm. Plus the sim card for sprint phone is soldered in so unless you know how to do that...

Yeah kinda. But I was thinking it would be easier then that. So when u take it over to Europe u couldn't even put a simcard from Europe in? That kills the function of being a world phone.

T-Mobile / Simple Mobile / Galaxy S3 ?

Until recently I have been with Sprint. And I am located in South Florida.
I am considering going with Simple Mobile as I'm told that T-Mobile has one of the best data speeds in this area. And I want to get a Galaxy S3 as the phone to use with this service.
Can anyone here advise as to whether this would work with Simple Mobile (I called them but they won't say anything only that they don't don't support it - meaning they don't sell it so don't bother them), at what speeds?
I also assume that I must get the T-Mobile version of this phone. That seems quite difficult unless I want to pay a big premium to T-Mobile, who charges much more than say AT&T for their version. So if anyone has any suggestions where I can get one (I would prefer a store, not eBay)?
Thanks
try the xda marketplace
edit: nvm just saw you dont have enough posts.
I read that the Sprint variant of the S3 would work on T-Mobile. You just have to unlock the phone I believe.

I remember negri sells the phone for $599 unlocked. That's the cheapest I've seen for the TMobile version. It's not cheaper by much but it's unlocked and you may save on taxes.

Sprint is cdma and T-Mobile is GSM. How are you going to stick a sim card in that sprint phone?
Sent from my SPH-D710 using xda app-developers app
My wife is using it on Simple Mobile. It works great.
Simple Mobile is a Mvno of t-mobile so you don't need to have an unlocked T999. Just change the apn. A's far as speeds. I live in Central Florida and I get the same speeds as t-mobile. I recommended. As far as where to buy the phone. I went to t-mobile and paid $599 for it. Haven't really seen it cheaper.

It does have a sim slot but it's not user accessible.
It's hidden behind the plastic under the battery.
Sprint has taken this approach with all there LTE devices.
The only exception may be the Photon Q since it's touted as being a global device.

Anyone try using the Verizon micro sd/sim daughter board on sprint sgs3?

The sprint version does not have an external sim as you all know. My question is if you take the phone apart the sd reader is detachable. has anyone attempted to plug in a Verizon micro sim/sd reader daughter board into a sprint device and see if it would read the sim? I know it's a stretch but might be worth a shot to get working gsm...

Even thought the 4 carriers have the same specs it doesn't mean they all support the same bands.....

Sgs3 work on verizon ?

I have the chance to buy a sgs. Could I unlock it and have it work on Verizon's network? The sellers insists it could with the right APNs. Can any one enlighten me?

If the phone is manufactured for Verizon, like it says verizon on the device, then yes it will. However, if its a T-Mobile or ATT SGS3, then NO it wont work. ATT and T-Mobile SGS3 doesnt have CDMA bands.
If its a sprint SGS3, then yes you can unlock it to work on Verizon. Hope that clarifies things for you.
It doesn't have the right 4g bands?

That is correct there is complete incompatibility between the carriers cdma vs. gsm, CDMA is more frequently used here in the us its a older technology and GSM is more world wide the only phone i really seen that carries both bands are the iphone 4s

Any phone that sports the "global" tag will work on any carrier. Such as the "Droid 2 Global" and I believe that there is actually a worldwide variation of the htc one x or one s as well.

I heard the Verizon S3 is supposed to be "Global" however, remember that T-Mobile is special and uses that 1700 mHz aws frequency for 3g therefore global phones wont get 3g on tmobile. Like my Sprint Touch Pro 2 for instance

The only "global" phones that have CDMA bands are Verizon and Sprint phones in the US.
Why would a GSM carrier put GSM bands in their phone when you can use a GSM phone overseas already?
I'm not talking about overseas, I'm telling the op a global phone would work on any carrier...

But they won't. A global phone from AT&T or T-Mobile will not work on Verizon or Sprint. A Verizon or Sprint global phone is also not likely as the other carriers will not activate it. However it is much more likely.

I hate to burst your bubble, but your most definitely wrong. Most Gsm phones for the United States will not work overseas, its just the "name" of the US network. CDMA works transparently with TDMA. If you know anything about APNs and cat radios then you'll be able to figure it out.
I have personally cracked verizon for AT&T and vice versa.

So I can use a UK phone here, but I can't use an unlocked AT&T phone in the UK? That makes no sense. So why do people overseas buy unlocked phones from the US? So they can use them for paperweights?
The difference between GSM here in NA vs the rest of the world is the frequencies used:
Most of NA and SA use 850/1900 while the majority of the planet uses 900/1800. http://www.worldtimezone.com/gsm.html
So if you want to use a phone from the US overseas it must be at least Triband or quadband (more common).
For 3G to work outside the US the phone will also need the 2100 band.
Hope this helps.

Lol, GSM phones can be used worldwide. The only real big place that uses CDMA bands is inside the USA, almost everywhere else is straight GSM. Funny how people buy US phones from overseas, and never once have complained that they don't work. But I'll definitely take your word for it.
But since you supposedly can make an AT&T phone work on Verizon, mind getting me a Galaxy Note that works on Verizon? Unless of course its not possible, which its not.

[Q] Verizon lte 4g Samsung Nexus sch-i515

Hi guys new to the forums i did alot of searching and researching but just cant figure out a solution. I purchased this phone as a replacement to use in canada on the bell mobility network when i first recieved the phone i went to bell and tested with there sim card and the phone would not connect, so after being dissapointed i went home and downloaded and installed the Nexus Root Toolkit v1.6.1 and unlocked and rooted the phone hopping this was my solution after this i headed back to the bell store and tested again still no luck I am hopping someone has any ideas for me i really would like to get this phone working
thanks
From what I understand, Bell is a GSM network correct? Well, Verizon is a CDMA carrier. The SIM card in our i515 is only for LTE. That's it. It won't work on Bell, I'm pretty sure you need an unlocked GSM Nexus for that. Someone correct me if I'm wrong.
Bell Canada is not a CDMA carrier, you bought the wrong model, research first next time.

if its not from their website, uh yeah... they're pretty much GSM only from what i know of them

No... The CDMA Nexus will only work on Verizon. I believe some of the very small carriers will work but don't depend on it. I think Rodgers may have a chance, but VZW is very tight about its phones

You could probably manually program it with the tools autoprime posted here in general for 3G, Talk, and Text but you'll never get LTE on it.

Its all about what frequencies the phones radio has. My old incredible 2 had a different radio and could go to cricket, yet my nexus can't get to any other because of the fact that there's more than one CDMA frequency.

Can i switch to a Japanese carrier?

I see this as unlikely, but would i be able to bring my phone to japan and place it on one of their carriers? Ive read they use cdma, but how much does that matter when it comes to radios or bands? I just bought this phone and found out a week later i will be moving there in november. Not too happy about this since i paid retail for this beast.

It's called unlocking and basically unlocks your phone so it can use any carrier. Now it's illegal in the US but call up your provider ask and for the unlock code anyway. Say you have to go there in a couple of day and you need to use the phone. Normally they'll give it to you via email and the instructions are included in the email. All you would have to do after you unlock the phone is replace the sim card and you'll all good to go. Now don't go online and buy the unlock codes from websites because most of them are scams and even though some might work, its not worth giving them your credit card number and then be in deep yogurt. Hoped this helped

You can probably get kddi mobile in japan to add your esn for you. I'm almost positive they use the same 3g frequency as sprint, however I doubt you'll be able to get lte.

If kddi won't add the esn, you could get a cheap phone thru them and flash your note with cdma ws or find another mvno that will add it. Now that sprint and softbank are looking at a partnership I think softbanks carrier's will accept sprint phones for Americans that come over without too much hassle. Japan has a large cdma network (largest outside of US) and use the same frequencys and sprint as vzw so 3g should be no problem and neither should finding someone to add your esn over there. They're pretty good about letting Americans use their own devices when they come over.
