Hi, i've maybe a stupid Q... does this phone support the sim card???
http://www.anumex.com/pictures/2557923-1.jpg
because I read that there are special cards to lte...
can someone guide me please.
thanks for taking the time to read

This phone takes a standard SIM card just like other AT&T phones. It's not an LTE device.

This phone uses SIM Cards only..
Sprint version is CDMA.

Oh! Thnx For your fast Answers...
i say that because i see someday a table that say somthing about a lte chip x.x!!
ok, i hope to be in this subforum soon!

hm,
the Elevate 4G LTE Mi-Fi at work has the same '4G' sim that HSPA+ phones have.

LTE SIMs (technically called a UICC) are designed to be backward compatible with 3G and 2.5G services.

How do I findout if my phone is CDMA

ok guys I feel that I'm asking the dumbest question of all but I do'nt know how to check if my phone is a CDMA devise or a GSM... Can anyone explane to me the basic differences in a couple ot brief sentenses...
go here http://www.wisegeek.com/what-is-the-difference-between-gsm-and-cdma.htm. this will explain it
Thank you I read a thread that said that CDMA don't have sim cards... GSMa do have Sim cards and that was the main differense.

Different technology in a number of ways. Most of these are not visible to the naked eye. CDMA doesn't use SIMs, but some CDMA devices also have a GSM radio so have a SIM for that. This doesn't apply to the Touch Pro (but probably will to the Touch Pro 2), but if you're not familiar with the device specs the presence or absence of a SIM slot alone won't tell you if it's a GSM device or not. There are other non-GSM technologies besides CDMA, too, so it can get a bit complicated. With a TP, though, checking for a SIM slot will answer your question about whether you have a CDMA unit or not.
If you currently have service, you can also tell by your carrier.

[Q] Does Thunderbolt have a SIM slot?

I've been told that LTE is GSM tech and requires SIM card. HTC is LTE capable device. Can anyone tell me if the Thunderbolt does actually have a SIM slot? or I just have bogus information from people. Thanks.
yes the Thunderbolt requires a sim card
Yes

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).

[Q] Sim card support?

Looking at pictures of the Rezound, it looked as if it has sim card support, is there any known way to root/unlock the phone to use on T-mobile/AT&T?? if so i need one...
no the sim card is for LTE only. Sorry! It doesn't have GSM or HSPA support. Only CDMA EvDo 1xRTT and LTE
Ah bummer. Well ill definently have to consider virizon instead of tmobile when i get my own contract
Sent from my SGH-T959V using XDA App
Excuse my ignorance, but just trying to sort this out. Realise it uses an LTE sim card, but as I live in China was hoping to put in a china telecom sim card and use it on their CDMA2000 network (which it does support).
This possible? Thanks in advance.
The sim card is solely for LTE if that helps. It may be possible to flash it to their network but I cannot answer a yes or no
It depends on the spectrum your LTE network uses. The phone should function CDMA only if you or your carrier know how to flash it correctly. Verizon uses a special LTE spectrum range they bought from the FCC known as C-Class if I remember correctly. It was sold after the US went from Analog to Digital TV. There were A-E Class Spectrum and C apparently was the best for whatever reason. I don't know to say anyone on here would know any more info than that in regards to the frequencies.
Thanks, I don't know how to flash it and I assume my carrier probably doesn't know how to or want to either. Shame. Really wanted this phone. It is being sold on taobao here (Chinese ebay equivalent) so maybe a solution will be found in the future.
There is a program called CDMA Workshop that most places in the US use to flash CDMA phones from major carriers to pre-paid carriers. I am sure someone over there could do the same. I lived in South Korea for 2 years, the stuff they could do was ridiculous, and I know China is the same. Actually, my neighbor is from China and is pretty tech Savvy too. I will text him later as he was just in China a couple weeks ago.
He said his girlfriend was able to bring her iPhone from China and have it flashed. Should work the other way around. As far as LTE though, beyond me.

[Q] World phone capability

If the qualdcom processor on the EVO is ment to support LTE which in turn uses a sim card shouldn't that make the phone a world phone I know it is suppose to have an embeded sim. But my true question is will we be able to reporgram the sim once we get root or will write have to go with more of a hardware mod if we wish to make it a world phone.

Sprint uses embedded LTE technology to my knowledge, so its not like on Verizon where there is an LTE sim card. Also, this phone is a CDMA phone, and therefore does not have a regular sim card slot (Like phones on ATT or TMo). No software modifications will change this, and I highly doubt that anyone could even attempt to make a hardware modification to make this phone a world phone. Also, and LTE sim card is not the same as a regular sim card, as they perform different actions (access to LTE and the rest of the network is seperate).
Yeah I was thinking that it does not have the slot the thing is that the processor does support gsm also I was kinda hopeing it was like the rezound it is cdma phone on Verizon. It was found out that just by removing verizons LTE sim card and adding a gsm one it allowed the phone to work as a gsm phone.
the evo lte does not have the GSM and HSPA+ radios to be a world phone
When I preordered, the rep told me it was a world phone. I didn't think she was right but I didn't say anything.
Yeah i read the same post on Engadget i think. What a bummer was hopping it was since it is rocking the same processor that the at&t one (correct me if im wrong). Plus like i also stated was hopping it was like the HTC rezound on Verizon that with a experiment it ended up working. O well .... still kinda wanna take it apart and try wouldn't be xda without some experimenting or moding.
My friend has a Droid bionic which wasn't supposed to have GSM support, but it did through some hacks on rootzwiki and using a T-Mobile sim card. I think that the s4 includes a GSM radio, so its probably possible at least if the sim card can be accessed. Lte is GSM based so it is likely that GSM support is there if software is modified like it was on the bionic.

Sure, you can use it anywhere in the world that has a compatible CDMA network.
Many identify world phone with GSM radios (which the Evo 4G LTE does not have), but CDMA (which it does have) does work well for roaming in Asia.
I've roamed with my Evo 4G across Japan, Korea, and China for both voice and data. There's a full list of countries with CDMA roaming on the Sprint website. As soon as you arrive in country (if roaming works), you receive a free text with the rates and instructions on how to make international calls.

Will rogers/Bell SG3 imei be on ATT database ?

basically i wanna know if the bell/rogers i747M imei would show up on att imei database ?
i wanna use the non-smartphone unlimited data with it if possible
also whats the diff between the i747 and i747M ? only software ?
if you're trying this in order to use LTE, it won't work. you'd need an LTE simcard in which case AT&T will know you're on a real smartphone.

You actually don't need an LTE sim card. The HSPA+ sim cards that was previously used still picks up a LTE signal.
