Getting my droid 3 from ebay tomorrow. Do i need a sim if im just using it in u.s.?
It isn't the question but the way its asked.
That depends on what you intend to do with it. For most users, no.
No I have my global sim card out and it does not require a 4g sim either because... well because its not 4g.

That's not a stupid question. You need a sim card to use it in the US as well.

This is a Verizon phone and Verizon has never used sim cards because they are CDMA. The sim card slot is for GSM signals in other countries, since US based GSM providers like at&t and t-mobile are blocked on this.
Thanks for the replies. It came with one....but as I found out, its not needed for U.S. operation. BTW....loving the phone(even without root).

Apparently they now carry 4G SIM cards to allow access to their LTE network (see here). The details are a little sketchy, though, and I wouldn't bank on it working.
If you're really interested in doing this, I would suggest going directly to a Verizon store and speaking with someone there. Maybe even see if they'll let you test it out (probably not, but it can't hurt to ask).
The only other Verizon sim cards I found were international ones that allowed roaming on Vodafone's network. Since Verizon in the US uses CDMA for its non-4G network, SIM cards don't work. With a non-4G SIM card you would end up piggybacking on some other carrier's network.
That's my understanding, anyway.
Okay I have a droid incredible 2 it got damaged but it has a sim card its not 4g either so yeah

That's one of the international sim cards, which basically just lets it hop on GSM networks internationally when it doesn't have Verizon's US CDMA network.
So you mean its not possible
Sent from my SAMSUNG-SGH-I897 using XDA App
I can't say for certain. You would need to talk to someone at Verizon and ask them if their international GSM sim cards work here in the states.
My guess is that they'll tell you it will work, but since you would be essentially roaming all the time you're using it, it would be either costly or they wouldn't do it. Again, I'm not a Verizon employee, so I can't say that's 100% accurate, but that's my gut reaction.
Yeah ok makes sence my incredible 2 can only go into safe mode thats why I ask this

Yes but verizon is so protective you have to have them activate it through the phones imei

Unfortunately verizon does not like you to be able to use at&t on there global phones so afaik there's no way to make it work.
Ok I searched and didn't have any luck with what is prolly a really dumb question.
I understand that these units take a SIM card for the 4G LTE. My question is if this is compatble with ATT or T-mobile. In other words, can I have a 4G T-Mobile SIM card and put it in this phone and get data? Can I put this SIM chip in a t-mobile phone and get data on it? Same with ATT.
Thanks!
No.

I use unlocked D3 but this device is 512MB ram also there is no official ICS(no flash reader, no camcorder). If I can use D4 on gsm network, I'll upgrade!

Yes you can, but currently only with the leaked ICS firmwares. The stock gingerbread firmware does not allow it. Supposedly the official ICS firmware is due in Q3 2012
I made a thread here with instructions on how to do it http://forum.xda-developers.com/showthread.php?t=1766479
Will this work if the droid 4 has a bad ESN?

Should be, the esn is usually used to activate cdma, for gsm you only have to activate a sim card and put it in...

Almost the answer I was looking for.
So could someone confirm this:
Bad esn doesn't affect calling via a SIMcard?
I know it's a very old thread, but worth trying..
ESN's and IMEI numbers are used for GSM phones(AT&T, T-Mobile and now Verizon also). MEID numbers are used with CDMA phones(Verizon,Sprint) and just because the phone has ics or jb doesn't mean it's unlocked. You still have to install a different sim card and put in an unlock code which you can get from Verizon if you are with them or pay for it online somewhere. Once the new sim card is installed into phone and the unlock code is entered, the phone will state that your device has been unlocked. Unlocking phones is mainly for overseas use outside of the US. I have much experience with this as I served in the U.S. military for 10 years and I took my old phone over with me. Upon arrival in the new country, you set up cell service with a GSM provider, install their sim card and viola! Hope I could clear this up for you guys! Not trying to sound mean, just informative.
EDIT: Bad ESN's or MEID's can be a bad thing but some can be changed or flashed over with new one's from third party service providers like PagePlus Cellular, etc.

I may be spending a long time in the UK before my 2-year contract is up (study abroad). If I leave the country for an extended period of time, will Sprint unlock my One so I can use a local SIM while I'm there?
No because that sim card isn't for gsm networks its just for the lte on sprint. The way lte works it requires a sim card to work

I thought the HTC One was the first Sprint phone where you can take out the UICC (SIM), the rest, i.e. the SGS3 and EvoLTE, have an integrated UICC. So the EvoLTE does have a SIM, its just tucked inside where you cant remove it (not without modifying the unit itself anyways).

That I'm not sure about. It's above my understanding lol. I do know I don't have a sim card I can take out and the HTC one is an international phone but I guess the world bands aren't up and running yet.

Its internal. All Sprint LTE phones need a UICC. Check your about phone settings, your ICCID should be your UICC.

It does have a sim card in it, that is why there is a sim card punched out in the package. If you have a sim card ejecter, you would put it in the tiny hole next to the sim tray and it would eject the sim card out.

The EvoLTE has an internal SIM, youre not gonna see it. The first Sprint phone that has a swappable SIM is the HTC One. The SGS3, EvoLTE, Note II, LG Optimus -among others- all have a SIM inside of them.

That's not 100% accurate. Before it started with its LTE upgrade, Sprint did offer some phones that had swappable SIMs.

Alright, let me fix it: the first LTE phone with a removable SIM is the HTC One.
http://www.pcmag.com/article2/0,2817,2417502,00.asp
"This model of the One supports Sprint's 3G (CDMA 800/850/1900) and LTE (1900 only) networks, along with GSM/EDGE on 850/900/1800/1900 and HSPA 14.4 on the 1900 and 2100MHz bands. That means this phone will roam internationally at 3G speeds. In theory, you could unlock it to work poorly on AT&T's and T-Mobile's networks, but it wouldn't be able to take advantage of fast speeds on either. "
It wont work in TMobile USA. It doesnt have the 1700 band.

That information may not be correct. According to the FCC filings there is no mention of the 850/1900 GSM bands.

Hey there. I got this new moto x and have been holding off on is upgrades until I can get my bearings on what I need to do to ensure fully unlocked and customizable phone in the future as I caught wind of issues doing so post kk. Twice now my Sim has stopped working. Wondering if this was a known issue or if I need to investigate prior to visit the warranty
Thanks in advanced for any feedback.

Just understand that if you really have an XT1053 on ATT, it doesn't support all the bands ATT uses for LTE so you'll fall back to HSPA

Right, the missing LTE bands shouldn't cause total loss of service.
For ATT there is 4G HSPA and 4G LTE.. not sure how the GSM varients report each. And the XT1053 does support the primary LTE band ATT uses.
Hey there,
I had the same issue. Got a XT1058 and am using it on T-Mobile. I kept loosing signal completely. Sim Card not recognized.
The problem I found is that if you are using a sim card that has been cut to fit the tray will cause signal loss issue.
Went to T-Mobile got a new sim card and been using it without a problem.
Let us know if this helps you.
