Which version TP2 can I buy?

I'm planning to buy an TP2 from ebay but I couldn't decide which version(s) are compatible with my country's cellular networks. I use Vodafone in Turkey and Vodafone uses GSM 900 and UMTS 2100 bands. I read the forum a lot but I got very confused.
I'll use both UMTS and GSM networks because the UMTS covarage is limited in Turkey so far. I'm looking for Sprint or AT&T versions but I didn't understand if need to unlock these devices or not. In a thread I read that Sprint is unlocked for GSM networks but the same thread didn't mention anything about UMTS band. Please make suggestions to me.
I hope that I could explain my concerns clearly.

That should have the information about which phone you need. You can always unlock the phones, so make sure it has the correct GSM/CDMA networks and you should be fine.
*edit*
I should have mentioned this before. Sometimes carriers are really picky about which phones they will activate, make sure that Vodafone will activate the model TP2 that you get.

The Sprint TP2 will work for you in its stock configuration.
It supports GSM 900, GSM 1800 and UMTS 2100 out of the box and it is NOT SIM locked. Basically all you'll have to do it pop in your SIM card and go.
Now, you will still have to register the IMEI with customs (assuming Turkey still has that stupid ass rule) so it doesn't get blocked from the network, but aside from that you're golden.
If you get the ATT version it will also work, however it will be SIM locked out of the box and you will have to unlock it to use it. The same is true of the Verizon TP2.

I read that thread 3 times But the the explanations about GSM does not contain UMTS band so i need to ask. Thanks for your reply.

Thanks. This was the exact answer I expected to get.
On ebay i found a Sprint with bad ESN. In the descriptions it says that it can be used in any networks other than Sprint. Can I use a phone like this in Turkey with confidence?

Yes. A Sprint Touch Pro 2 will work just fine with a Vodaphone SIM so long as your local network is one of the three frequencies that I listed.
You only need to replace the Radio ROM if you want to use it on US GSM frequencies.

Thanks gamescan. Does a bad ESN phone be a problem for me?

Bad ESN means that the phone has been banned from its home network.
This usually happens because:
1) There is an outstanding bill that was not paid
2) The phone was reported lost and claimed on insurance
3) The phone was stolen
If you are using it on another CDMA network or on a GSM network, the bad ESN will not impact you (aside from possibly in a karmic way).
If it does have a bad ESN you should get it pretty cheap.

Verizon DROID 2 to GSM 1900/900 Optus Network?

Hey Guys, I'm interested in getting one of those R2D2 DROID 2 phones and I wish to use it on the optus network in Australia.
I believe optus uses a dual band 900/1900mhz ?
Some questions I have are too people that have tried this already.
Will the 3G data work on this phone?
How difficult and what modding needs to be done on this phone to get it too work?
Thanks for the help peeps : )

Let me get this straight.
You're asking whether you can use DROID2 R2D2 (a CDMA-only device that supports CDMA2000 and 3G CDMA 1x EV-DO Rev.A) on Optus's GSM network operating on 900/1800MHz bands with 3G UMTS/HSPA?
So, you want to use a pure CDMA device with no GSM support whatsoever on a GSM network, right?

Hardware wise this is almost identical to the milestone 2 right? I've heard that in other countries with the Verizon phone roaming is enabled so it would work with other networks? Excuse the noob question. How is cdma different to GSM?
Sent from my U8160 using XDA

CDMA is one standard. GSM is another. There is almost nothing similar between these. Here's a question: how do you fit a GSM SIM card into a DROID2 R2D2? It has no SIM card slot.
Verizon CDMA devices can roam on CDMA networks.
Verizon Global phones can use GSM networks, because they have a GSM+CDMA transceiver in them.
The DROID2 (and the R2D2 variant) isn't a Global device.
The DROID2 GLOBAL is.
Please refer to http://en.wikipedia.org/wiki/CDMA2000 and http://en.wikipedia.org/wiki/GSM so that you can stop asking these… weird questions.

How is it a weird question?
Some have modded/flashed the DROID 4 which is CDMA phone to work on GSM.
I am merely asking if its possible or if anyone's tried it.

DROID4 is a Global device. It has a CDMA+GSM+LTE transceiver.
DROID2 doesn't.

Verizon GS3 "World", "GSM", or ???

The GS3 Verizon is a CDMA device. Supposedly it has GSM compatible radios too. It's supposed to be able to work on GSM networks after a software update coming soon. Does this thing have a sim card slot? I don't see how it would work on GSM networks without it. Does anyone know how this works?
I'm hoping to use it on Verizon in USA, but on Telcel while in Mexico BUT with my Telcel sim. I realize my hopes are slim but if there's a sim card slot maybe it's possible???
Thanks.

It has a SIM card slot for the LTE. Unsure about compatibility though.

Actually, I have an old Verizon Motorola Z6c World Phone here that I bought in 2008. It has a Verizon sim card inside.
Z6c Specs say:
2G Network GSM 900 / 1800
3G Network CDMA 1xEVDO (800 / 1900 MHz)
Anyway, there's no LTE involved on the Z6c back then. SO apparently the GS3 will need the sim on non CDMA networks. I just wonder if the software experts here can make it possible to use the sim only at certain times and at the same time unlock the phone.
A lot to ask but will be a huge feature if done.

I said earlier that I wasn't sure about compatibility, but I'm starting to believe that this is not possible, as the Verizon version lacks the proper GSM/HSPA+ radios. There's a model comparison chart that you can expand on the Wikipedia page. Software probably won't be able to pull the miracle you're asking for. Sorry

Maybe this will help? http://androidcommunity.com/verizon-may-enable-global-roaming-on-lte-phones-soon-20120518/ from what I gather LTE is based off of GSM and its just a matter of unlocking the GSM bands on the phones.

The SCH-i535 did recieve GSM certification for bands 850 and 1900. No HSPA+ though.

Yeah, I don't think the current specs out on the GS3 are totally complete. If the phone is admittedly needing a software update to allow the GSM roaming then they can't just put those bands in the specs with no caveats.

Rogers Razr HD XT925 on Verizon?

Based on what I have read, given that the Rogers XT925 operates on the following bands:
Rogers version is GSM/UMTS - 850/900/1800/1900 and LTE : BAND 4 (700) and BAND 17 AWS (1700)
It is therefore impossible for it to work in the USA on Verizons network on either CDMA (which the phone does not support) or LTE (which it supports but the wrong band, Verizon supports 700 Band 13)
Can anyone confirm this? If it is possible to operate this phone on Verizon please let me know. I have a Verizon account and an AT&T account and the phone works on the AT&T account, but not the Verizon. My problem is that AT&T has recently blocked the IMEI on TWO of my Rogers phones that I travel with, with no explanation other than that they are being recognized as 2G phones and cannot get service on AT&T (which is BS, because I can roam with my Rogers SIM from my Galaxy S3 onto AT&T just fine), so AT&T is clearly blocking IMEI's of phones that come from other providers and are unlocked. I cannot see how this is good business for AT&T, or even legal, and I imagine one day there will be a class action suit to stop this practice.
My two cents...

Yes some friend have same problem as you ... have a rogers simcard ... use a little on the ATT network ... switch to ATT simcard ... and phone don't work ... really a strange issue ...

[Q] wcdma phone on straight talk cdma network. please help!!

Hello! I have been at this for a week now.
This is my situation, I bought a fully unlocked dual sim wcdma phone (Mpie 909T) running 4.4.2 KitKat.
I want to use this phone on my straight talk plan, but I only get service from Verizon wireless where I live.
I did some searching and found that I could use a R-UIM card to pick up signal from Verizon BUT I can not find where to buy one at (unless I buy bulk for a couple hundo). So I'm at a loss. I didn't realize that I didn't get service from at&t or T-Mobile till I got the phone and went to the straight talk site and it told me to buy a sim card activation kit, (checked on AT&T site to make sure I would have service and it showed that I would)... so I went and bought the kit only to find out that they actually don't have service out here. ? so if there is no way to find a r-uim card, would there be a way to change the radio frequencies in the phone? But I would also need a MEID # to activate on straight talk CDMA (Verizon towers). Or can I get one of those sim read/writer kits on eBay and program it to work?
I have not rooted the phone yet.
PLEASE HELP!!! I love this phone!!
I've been using the phone via WiFi from my old dx2 that's currently active.

Sadly, you cannot access a CDMA2000 network like Verizon's from a device that does not have a CDMA2000 transceiver. CDMA2000 is technologically incompatible with GSM and UMTS (sometimes called WCDMA). There are some dual mode devices, but Verizon explicitly forbids non-Verizon devices on their network. Even if you could somehow get a RUIM for Verizon, and their blessing to use it, your phone would not work unless it specifically has a CDMA transceiver in it. (remember, CDMA and WCDMA are not the same)
You need a device that supports not only the right technologies, but also the right frequencies. Most Dual-SIM phones are based exclusively on GSM and UMTS/WCDMA, and often operate on frequencies that are not comparable with US GSM operators. AT&T operates on GSM850, GSM1900, UMTS850, UMTS1900, and several bands of LTE. T-mobile operates on GSM1900, UMTS1700, UMTS1900, and several bands of LTE as well. However, most networks outside the Americas use GSM900, GSM1800, UMTS2100, and LTE800, 1800, and 2600.
You can use a site called GSMArena to check which bands your device has. If you want to use a CDMA carrier (Verizon, Sprint, and many rural operators in the US), you generally have to buy a phone with their branding or one of their partners.
Sorry to be the bearer of bad news

I have similar question. Since I am currently using ST with a Verizon phone ( CDMA) could I buy a new phone to replace current one ? And does it need to be another CDMA phone? And what is LOCKED/UNLOCKED have to do with it ?

This is a very large problem. I am in the same boat. Up here, we have Verizon,and ATT. that's it. My first phone here was ATT. worked great in town. As soon as I got to my house dead.,... I bought a Nexus 6 popped the Verizon SIM in it called straight talk they registered me on Verizon's network and boom Full LTE, and VoLTE. My issue now though is I want to try other devices and it seems that the N6 is literally the only non branded phone I can use. There are some awesome new Chinese devices I would love to try and on paper have the correct signals but still claim no Verizon. I am frustrated and stumped after weeks of research and conflicting reports. Does anyone know what is going on? Thanks in advance
