I am not sure I understand what you are saying but you will have to get a new sim card, one that supports lte.

You can use the same SIM card. You just won't get LTE.

If you have LTE in your area then yes. Go in and say you need a new sim card. They will probably charge u a nominal fee

ATT shouldn't charge for new sim - only if it is not a corporate store.

U do not need a diff sim if u have the 4g already ....I came from inspire and didn't have to change my card and my LTE works

Hm. I came from an Inspire and couldn't get any data til they gave me a new SIM...which confused me, but I didn't have data with my old SIM, then I had data with my new one...so I didn't ask too many questions

I came from an HTC Aria and had to get a new SIM, something about it being provisioned for LTE.

This. AFAIK, the new SIM card allows you to use the PTA APN, at which point they put you on the LTE "equivalent" of your current data plan.

I think it has something to do with how new Ur card is mine didn't have to be changed just he had to provision it that's it

Confirm need to switch sim or can you alter APN settings on phone to pick up LTE?
So, I went from a galaxy s2 with unlimited data plan, very expensive, but my SIM won't pick up LTE when put it in my new Htc Vivid....so are you saying I have to have a new LTE SIM?
Will AT&T give me one as I would think they want traffic to move over to the LTE service if I am already paying for an unlimited plan?
Anyone run into this?
I cannot change my plan to anything more expensive as it is a corp plan but it is already an unlimited voice data plan....

Is it unlimited data as well? I was under the impression that lte was for data and phones calls switch back to a lower network setting. If it is unlimited data you would need a new sim to take advantage of the lte. They should not charge you for the sim, I got it for free when I upgraded to the vivid from the captivate.

That is the case.
When they provision your plan, they put you on the LTE equivalent of what you already had. No change in price or terms or anything. You just have Smartphone Unlimited LTE instead of Smartphone Unlimited or whatever it's called.

Hi all, you were correct, ATT store gave me a new LTE capable SIM, the weird thing is that the only APN setting on the phone is called PTA....and won't give me any data connection at all, I am NOT in a LTE area now but I would think it would revert to the system that is available, 2g,3G or Hspa?
I added another APN but does this mean I have to manually switch back and forth when I get into an let area? This seems ridiculous?
Any advice I would appreciate?
Is there one APN setting that will do it all?

Other question. I am on infuse 4g (4g sim card in it) wonder iif I get other phone from Verizon or T-Mobile that has 4g and unlocked. Will I get 4g speed from them or what??
Thanks

hi, Infuse is a GSM phone so no Verizon....
As of now...tmobile sim might work but would only get you 2g...and you have to do a SIM unlock...tmobile 3g only works on 1700 band and Infuse has 3G bands of 850, 1900 and 2100 (UK band).....
Now, article today mentioned tmobile might open 1900 band on their hspa+ network but it is later this year and again you would have to SIM unlock...hspa+ is a pseudo 4g...it is not LTE but much faster than typical 3G,...that could work for ya...
Hope that helps.....

Data-only SIM cards?

Now that we can SIM-unlock our Sprint HTC Ones, I've been curious about buying a prepaid a T-Mobile SIM to use when I can't get LTE or decent 3G. My friends on T-Mobile get great HSPA speeds (even when it's just HSPA 14.4) around Chicago, usually in places where my data sucks.
Ideally, I would like to pop a T-Mobile SIM card in my phone, but still receive calls and texts on my Sprint number without setting up some kind of forwarding service. Unfortunately, I suspect that SIM cards don't work in this fashion, though I am hopeful because the removal of the SIM on the Sprint HTC One simply cuts off support for LTE (probably because the only purpose of the SIM card in the Sprint HTC One is to authenticate LTE, but I'm not totally certain).
Alternatively, could I jump between my Sprint service and T-Mobile service if I installed a T-Mobile SIM by using the *#*#4636#*#* menu? Say I chose "EvDo Only," would I connect to Sprint 3g and get calls and texts on my Sprint number and simply select "WCDMA Preferred" when I want to use T-Mobile's HSPA network?

On paper you should be able to connect to HSPA 14.4 on 1900MHz or 2G on 1900MHz. In actuality I don't know but there have been several other threads discussing similar topics. Here's one: http://forum.xda-developers.com/showthread.php?t=2386408

When I tested my T-Mobile sim, once I went into mobile networks and selected it, my phone number and my sms was thru the T-Mobile. So I don't think it will work as data only by default at least not saying that it is not possible, just sharing what I experienced.

Oh, this I know, thanks though. Actually, I was telling someone else just that earlier today:

The Sprint HTC One ONLY supports LTE on band 25. There are currently no carriers in the world other than Sprint that supports LTE on this band.
http://en.wikipedia.org/wiki/List_of_LTE_networks
EDIT: Oh, and the Sprint HTC One supports HSDPA on the 1900/2100 MHz UMTS bands up to 14.4Mbps, which is is slower than a lot of HSPA/HSDPA speeds available now (21.1Mbps and 42.2Mbps), though still more than fast enough for browsing or even streaming.

So you can leave a T-Mobile card in there and just switch between Sprint 3G/voice as well as T-Mo 3G/voice at will? That could be useful; for example, my favorite bar is a total dead zone for Sprint data, but T-Mobile flies. When I know I'm going there, I could pop a T-Mobile SIM, switch to that to check websites and whatnot, but switch it back to periodically check my text messages, right?

That I am not sure. I only tested with a friend's sim card from his nexus 4. With the Sprint sim card removed I was still on sprint cdma but once I went into the available GSM networks and chose T-Mobile, it registered and I was no longer on Sprint at all and it shows GSM icon up where my signal is at. Made a phone call and phone call came thru under my friend's phone number instead of my Sprint number. I'm not sure about sms I did not really played around with it long enough as I was just testing if the unlock really worked.

yes it work

Hmm... I might just stroll over to a T-Mobile store today, activate/pick up a SIM for $10, and spend another $3 for the daily pay-as-you-go plan. 200MB for $3 isn't bad if you need it in a pinch...

I've heard of these issues, does it happen if you stay in the same spot? Have you tried different modes in the *#*#4636#*#* menu other than "WCDMA Preferred"?

Just an update: I went to a T-Mobile store over lunch to buy a SIM. I was prepared to drop the $10 for the SIM and $3 for the day pass, but it turns out I would need to buy a $10 minimum plan first. >:-\
I'd rather not spend $25 after tax just to see if it works. I'll ask my friend on Sunday if I can try hers. Hopefully I'll be in an area that's covered in 1900/2100MHz.

Once ur SIM unlocked it will work with any SIM card ur just limited on the antennas the phone has. Our phone supports voice 3g and minimal 4g on domestic carriers. The 4g has to be on 1900/2100 mhz in order for this phone to pick it up

Ehh... Not really "4G" since the Sprint HTC One only supports LTE on 1900MHz band 25. T-Mobile uses 1900/2100MHz for HSPA, and the Sprint One only supports 14.4Mbps on those HSPA frequencies (much slower than T-Mobile's phones support).

I see what you're saying, and I think that you're right, but their HSPA network (which they suddenly started calling "4G" strictly for marketing reasons) is significantly slower than most LTE networks. Only phones that would run on HSPA 42.2Mbps would give Sprint phones a run for their money. HSPA was never classified as even being a pre-4G network by the ITU. I think that only WiMAX and LTE hold that distinction. Anything that's HSPA but marketed as "4G" is a lie.
Sent from my Sprint HTC One

If you're in a Sprint 3g only area then t-mobile if on 1900 hspa is still faster. If you integrated your sprint number with Google voice the you can still get your sprint text messages from the Google voice app and use an app like talkatone or groove ip for voice over ip

So I am not intending to get into a large debate about the HSPA ver of 4G vs the LTE networks other than to say that the top four carriers are not really using LTE to its truest potential because they're limiting backhaul connectivity to keep costs down. So that LTE network you're connected to doesn't have the fastest ethernet connection it should so in many cases it is "possible" for 42MB HSPA network to actually be faster in its actual deployment.

[Q] Moto X Republic Wireless

Hi. Greetings to all
I'm from Malaysia, and I'm interested to buy Moto X from RW since it's cheaper than DE. And I'm sure it's locked, but does it support GSM network? On wiki it writes unknown. Before, it used to share the same column as Sprint

Since RW uses Sprint as its network, the Moto X you buy from them would be CDMA.

The phone is CDMA but it does have a SIM slot. So I'm wondering if it's possible to use with a GSM carrier. Or how to even root this phone.

The sim card is for the lte.

That's the thing. Is it really CDMA? If I'm not mistaken, a CDMA phone doesn't use a SIM and doesn't even have a SIM slot. So, what's the SIM slot for? If one can put a SIM card, shouldn't it mean one can also use the GSM network? No?

Sure, LTE is the reason for SIM.
CDMA is a single-band network (hence why previously you could not talk and surf the web simultaneously). In order to connect on the LTE frequency, the SIM (Subscriber Identity Module) card identifies the phone for registering on the network.
Sprint uses 850Mhz for CDMA and 1900Mhz for LTE.

Every LTE phone uses a Sim. Because LTE is for one thing a gsm technology.
The republic wireless moto x hardware probably does support normal non LTE gsm as its the same hardware as the sprint model . that said its probably boot loader locked and firmware locked to not support gsm . they are not that dumb to let people buy the phones to not use on their network .

[Q] Nexus 6 3G/LTE issues

I have a Nexus 6 that I bought from Motorola.com and am using it with an activated nano sim card on Verizon. Previously I have had no problems with getting signal (LTE or 3G) but now that it just updated to 5.1.1 I can only get 3G when network settings are on "LTE/CDMA" and I get LTE when set on "LTE/GSM/UMTS". I am in an area that has pretty strong 4G but cant get it unless I change the setting. Has anyone else had a problem with this? Also I am open to suggestions for alternate ROMS that have been found to work well on Verizon. Thanks.

Verify that you are using the correct APN. However, I believe the correct setting for you would be LTE/GSM as Verizon is a GSM carrier.

LTE/CDMA works fine for me on Verizon.

Verizon is not a GSM Carrier. They are CDMA just like Sprint. The only reason both companies use SIM cards is for LTE only.

Thanks for clarification! I thought AT&T was the other CDMA and the rest were GSM besides Sprint. Again, thanks for setting me straight.

AT&T and T-Mobile are GSM, Sprint and Verizon are CDMA. Just for future reference.

Using an Unlocked Factory Image on Verizon

I have a Nexus 6 that has the Verizon image on it and would like to know if an unlocked Nexus 6 would work perfectly fine on the Verizon network or will I have to keep the Verizon image?
In other words can I use N6F27I instead of the Verizon specific N8I11B and if I do will I still get complete coverage on all of the Verizon network?

You can use whatever nexus 6 Rom you want, with or without a locked bootloader. So yes it will still work on your network
Sent from my Oneplus 3t

But will it work utilizing all of Verizon's frequencies and network?

Yep, because the bands are all preset at the factory. The version of Android you throw on the N6 has nothing to do with it.

So would there be any advantage or disadvantage of using the Verizon version?

That's something you're going to have to find out for yourself. I'm not on stock.

I use an unlocked AT&T N6 that I removed all the AT&T ringtones, bootup chimes etc. and have no problem using it on Verizon. The only Verizon app I use is "My Verizon" to pay my bill and it works without a hiccup.
