[Q] 4G, Prepaid?

So I had a Droid 3 on Verizon on a prepaid line ($95 for 450 talk, unlimited text, and unlimited data) but that was 3G.
With the gNexi coming out, I was wondering if I would even be able to use it's 4g capabilities on my prepaid line? I'm obviously going to buy it at full-retail price but will the 4G even work or will I be stuck on 3G all the time?
I can't do contracts...
Should I wait for T-Mobile to get it and use their 4G prepaid instead?

I'm unsure if VZW has a LTE prepay service. That's something you have to look into separately. My guess is they don't. Unless they explicitly say that your prepay covers LTE I would expect to only get 3G.
As far as switching to a different carrier no one can tell you which is better. Its all about where you will use the phone and its your call.

I just did an online chat with a VZW rep, here it is:
Please hold for a Verizon Wireless sales representative to assist you with your order. Thank you for your patience.
You are now chatting with 'Kiara'
Kiara: Hello. Thank you for visiting our chat service. May I help you with your order today?
You: I was wondering if 4G phones like the Droid Bionic are eligible for the Prepaid Smartphone plans???
Kiara: I do apologize for the inconvenience, although the Bionic is not able to be pre paid
You: Are their any 4G phones available for the Prepaid plans?
You: And/or can you tell me if there are any plans to offer any???
Kiara: I do apologize although at this time there are not
You: Ok, thank you for your help
So, looks like you can't, at this time, use a 4G phone on their prepaid plans.
I currently have a Nexus S on T-mobile's $30 month prepaid plan (100 mins, unl. text, unl. data*throttled after 5GB), and I love it but I don't use my phone much for calls... I plan on getting the Galaxy Nexus and using it on this plan once it's available.

Yeah it looks like I'll have to wait for the galaxy nexus to drop on TMobile
WoW this sucksss.... It probably won't even come out until late December...
Maybe I should just import? No idea how it works but I want my nexus asap

Look on the bright side... t-mo plans are cheaper than Verizon. So you'll save money if you switch. But then again tmo reception around your area would play a big role too.

Yeah I looked into it and Tmobile is way better than Verizon. I live in NYC so reception shouldnt be a problem at all. Now I'm just trying to figure out if I should import the 16GB model or wait for the 32GB US model :/ bleh ... I wonder when Tmobile will be getting it

If you have T-mo service in the area then its sooo much better. Just wait, don't import. You'll probably have to buy it unlocked (probably best buy, just like Nexus S) but you'll be better off for it. You don't want to sign a 2year for a Nexus on VZW and get blocked tethering and crap on it.

its all up in the air. As I said above ^, they might not "get it" officially at all. Might have to buy unlocked from Google/Best Buy.
But the winner is that the T-mo plans can be as low as 1/2 the price of VZW.

Actually they have a $30 Prepaid plan with 100talk/unlimited text/ and unlimited data (5gb of 4G) -- available only on new line activation.
Btw can you clarify the "unlocked from google/best buy" part? Would I still have to use a sim card if Tmobile wont officially sell it

yea their prepay options are pretty epic. 100min is a bit low for most though. I was just referring to their postpay options that are pretty cheap too. I've looked into moving from my EM+ no-contract plan to a prepay lately actually.

Well if you want my opinion I think they'll end up just selling it exactly like they did with the Nexus S. They sold it online, and they offered it via Best Buy unlocked. You'd buy the phone, then buy your service and get a SIM card from AT&T or T-mobile (or Simple Mobile, or whatever) separately and plug it in. The GN is pentaband HSPA+ and will work with pretty much any SIM in the world.

Speaking from personal experience, the problem with T-Mobile in NYC is that as soon as you are a few feet below ground level, you lose signal. When you can get 5 bars, it's great, T-Mobile probably has the least congested network of anyone, and you enjoy superb 3/4G speeds. But you will be frustrated by how spotty the coverage is. Go 20 miles North to Westchester or 20 miles east to LI and you'll often find yourself exiting buildings to get a signal.

Lol that's alright I don't leave the city anyways. What I am wondering is what happens when you deplete your limited use of the 4g data (I'll get 5gb). Someone told me that you get bumped down to EDGE(2G) speeds, but I thought you only go down to 3G.

As I (and many others) explained in the other thread about T-mobile:
- You get 5GB of data, that's 4g/3g/2g.
- Once you use all 5GB in a month, you get throttled.
- Throttled speeds are in the range of what EDGE is, even though your phone still says "3G" up in the status bar.
- Once your billing period ends, you get a new 5GB batch of data.
There's no discerning between 4G and 3G by T-mobile. HSPA+ is just a fast version of T-mobile's 3G network. Its not separate.

Just curious has any one looked into metroPCS they say they allow any cdma phone on their network and they have lte. There speeds may not be the greatest and not the best coverage but the price is spot on and unlimited!

Don't think it'll work. You'd have to unlock it somehow, and even then I think theres going to be inconsistencies with the LTE frequencies they use, etc.

I thought that all nexus devices where unlocked developer phones. also i just talked to metroPCS and they did say hardware wise any cdma ohone will work and so will the LTE but, there might be a problem with software incompatibilities. but if that is true i would think our fellow xda members would figure out how to fix any software problems

It won't be unlocked from the factory because 1) its CDMA/LTE with VZW specific bands, and 2) its being made to order for Verizon to subsidize it (which means they will SURELY dictate that its locked).
The Nexus devices have historically been sold full price without a carrier subsidy (and therefore are unlocked) because google wants them to be used anywhere in the world with any SIM card. This is different because there are carriers involved from the start (and the device is CDMA).
Also, I'm pretty sure the LTE won't be interoperable between the two carriers. Verizon will have their own proprietary network stack for use with their LTE service, and it uses slightly different frequencies from other carriers for LTE, specifically so that their devices won't be interoperable with other networks. They want you to buy a VZW phone and stay on VZW (dirty play, but that's how they roll).
Hope that clarifies things a little bit. Now no one knows for sure how much of the issues can be fixed with new firmware flashes, so I guess we'll see when it comes out. For example I know a lot of people use Sprint and Verizon phones with different custom firmware to run on networks like Virgin, Boost, and Cricket in order to cut down the monthly bill.

well lets just hope some one out there can figure out how to make a phone like this run on a reasonabale priced carrier well other than t-mobile

How likely do you think an ATT Nexus is?

which carrier do you think is better......

At&t is the least "Android friendly" carrier so I would kind of be surprised. I know in the 3+ years I had them I hated every minute of it. I am soo happy with VZW and will never go back. I also know that this is only my experience and reception differs through out the country, but in Northern AL VZW is the only carrier worth having if you actually want a working device - I have full coverage and LTE almost everywhere I go. With At&t I had a bar and edge. Doesnt At&t have LTE in like 12 major cities only? What is the point?
EDIT: Yes VZW is more expensive but its worth it to me to actually be able to use my phone.

I didn't think att was so anti android. They had the atrix. A killer device and came out eons before (10 months?) the bionic, the all but brother to the atrix, and they have their own S2 and S2 lte. Even a nexus s. I'm not butting heads intentionally. But I also know in north jersey (15 miles from Verizon HQ) my hspa+ smokes Verizon 3g usually 3megs to .75. And call wise no body in my area has att problems. BUT I do hear about them from other locations. But I digress. I don't see why att is android unfriendly and why we should give up on lte from them just because its new. They have 1/6th the coverage Verizon has which is good for such a small time its been out. Also the lte switching on att kills lte when not in use and vice versa. Tremendous better savings vs big red. Just my thoughts

For the longest time, they locked down sideloading of apps. Thats pretty damn Android unfriendly.

I was under the impression that Verizon did too. Am I wrong?

Nah, Verizon never did that. They like to bloat things up, but they do not lockdown sideloading or anything like that. Nor do they use CIQ like Sprint does on some of their devices.

AND THEN.. You have AT&T disabling HSPA on their Android phones but leaving it enabled on the iDevices, all the time marketing their Androids as HSPA CAPABLE. They are unethical liars.

VZW never prevented sideloading.

well i appreciate the clarity, i guess as having a decent selection of androids to me made me feel that way,
ANYWAYS do we have any input on the topic? i feel like some people dont care, but we are talking about an awesome phone being offered to people at a lower cost, sim card use in america with a faster radio and possibly more storage, and a 1 year warranty in america, im not sure if att would even have the ability to hamper the nexus experience with this so does anyone care or do we just want to hate ATT?

T-Mobile.. cheaper, allows tethering/hotspots, no android restrictions... dont know why people put up with att and verizon

I pay the premium to actually have reception, Tmo & Att have none in my area.. VZW has reception everywhere, and LTE everywhere too (in my area). VZW doesnt have "Android restrictions", and Ive never paid for tethering on any carrier nor will I - I get that for free.

Because T-mobile's service is garbage in a lot of places? Because they have unlimited data on Verizon? Because Verizon actually carries the Galaxy Nexus and there is no trouble getting warranty support?
There is actually a no service area for T-mobile within city limits here.

Can we use AT&T 4G LTE on these? Is the radio physically there?

I'm debating between the T-Mobile and AT&T versions of the SG3. I'm currently planning on using a prepaid T-Mobile service but I can see myself in the future possibly switching to a postpaid AT&T plan.
If I buy the AT&T version I will be stuck on EDGE when on the T-Mobile network. No one has gotten T-Mobile's HSPA+ or DC-HSPA+ to work on the AT&T version of the GS3.
If I buy the T-Mobile version I won't have the option of using AT&T 4G LTE if I choose to go AT&T in the future.
So: does the T-Mobile GS3 physically have the AT&T 4G LTE hardware, and could it be activated?

I looked into the exact same thing before taking the plunge. Apparently, even though they have the same hardware, there is a trade off no matter which one you choose, so short answer is no. (But who knows,there are smarter people out there who may prove me wrong...)
I can tell you why I went with the T Mobile version if it will help with your decision...
1. TMo ver will work with HSPA on both TMO and ATT (As you pointed out, the ATT will only get EDGE on TMo)
2. I previously owned 2 LTE phones and battery life was horrible. Giving LTE up was not that difficult for me since the trade off was batt life
3. HSPA speeds are enough for my uses (You will rarely ever get advertised speeds with either HSPA or LTE)

Got it. Thanks. Even if I go with AT&T I might not even want to use their 4G network since it hogs battery so much? I've currently got T-Mobile and the fastest I've ever been able to clock is a measly 5mbps. A far cry from even the "slow" 21mbps speed that HSPA+ advertises.

Also, ATT may or may not have LTE lit up in your area yet. You may be waiting for a while. I had an HTC Thunderbold and a Galaxy Nexus on VZW for a few years and it was only towards the last 3 months of my VZW service that I began to get LTE lol HSPA is much more widespread as of right now on ATT

Unlocking T-Mobile for AT&T service

hi everyone:
I have been looking via numerous thread online on many Android forums especially here and have been unsuccessful for the past 2 days now. So I figured I would need to create a thread and finally give in and ask for some help. I have a T-Mobile Samsung Galaxy 3 phone and I need to unlock it so that it will work on my AT&T service. Now i understand about rooting the phone and being able to play with themes etc, but its not that great if I can't use the phone itself.
Now without coming up with some kind of answer I must have watched about 40 youtube video's hoping to find out some kind of information. Mostly what I got out of it was numerous website that offer unlocking for phones at a certain price.
unlockcodesource(.)com
unlock2go(.)com
mobileunlockcodes(.)co.uk
Has anyone ever used any of these website or can someone give me some good advise on how I can get this phone unlocked please/
~Aqua

I think the toolkit stickied in the development forum has an option to SIM unlock the GS3. I have not tried this, and do not know if it works, but if the option is there, you might want to give it a shot.

If you're on contract with t mobile and your account is in good standing with them. Call them tell them you're going over seas and need to unlock your phone so you can use it. They will send you unlock code ... then pop in an att sim card and it will prompt you to enter the unlock code t Mobil gave you. Done

OK thank you. I followed your instructions and they said it would take up to maybe 24 hrs for the phone to be unlocked. If it isn't unlocked than she said to call back with the conformation number she gave me. If that doesn't work than they would have to give Samsung my info and could take up to 14 days. She said when you buy phones almost all stands and corp stores have already unlocked phones.
she also said it would be auto unlocked for good. Can they lock the phone back up once it is be unlocked?

edited: Once I have it unlocked ( if all goes good ) do i use the same APN settings that I needed to put into the phone in order for my phone to work on the AT&T network as I did with my S2 that I got unlocked ?

Don't they use different frequencies for HSPA+
You would be relegated to edge speeds, correct me if I'm wrong

The T-Mobile S3 has the 850/1900 3G bands so it will work on AT&T's 3G network. It will not get LTE though.
You can unlock either by paying for a code from the various resellers online or requesting an unlock code from T-Mobile if you have an account in good standing with them. If you can't get the code from T-Mobile I suggest searching 'T999 unlock' on eBay and you'll find some good options.

The tmobile galaxy s3 will work on the ATnT HSPA+21 frequency. Same frequency the International version runs on for that network.

Edge network and 3/4G Question
I found an excellent place so far on eBay for buying unlock codes. they have almost 3800 sells with a 99% positive feedback. Great customer service. The guy answered numerous questions of mine and made sure i did everything correctly. Payment was $24.95 US, so hopefullly everything will go good.
He was talking about being on something called an " Edge " network which is a little slower, but he said you won't notice a difference between your unlocked S2 and the unlocked S3 now. Right now my S2 says I have 3G service when I use it. I dont understand how i had a inspire4G, what is the 4G for if AT&T only gives you 3G service? And where I am in United States I should have 4G service no matter what. I'm confused on that.,

Edge is 2G speeds, which are substantially slower than 3G speeds. IMHO, 3G speeds are livable, 2G/Edge is not.
Different phones have different radios which work on different frequencies. Some phones are not compatible with other services at all, and some will work on other carriers but often not at optimal speeds.

So than why would someone suggest that I would get "edge" instead of what i have now? I'm getting 3G now with my T-Mobile S2 unlocked on AT&T, but now I'm going to have an unlocked S3, why wouldn't it be the same?

Because the radios in the devices are different.

Because he/she doesn't know what he/she is talking about. You will be fine with a T-Mobile S3 on AT&T.

That's what I said earlier in not so many words.
Voice willl work fine you will not see HSPA+ speeds on At&t with a T-Mobile Galaxy SIII.
If the T-Mobile SIII has the hardware capability to support the At&t HSPA+ bands you would need modified radio software to unlock this ability.
I believe this was done on the Galaxy Note to tun on T-Mobile HSPA+ network before it was officially launched on T-Mobile.
kmdub I believe your the one that's wrong.

I unlocked my t999 and am using an att straight talk sim getting HSPA speeds. Going to switch back to tmobile prepay because it is way faster than att HSPA with better latency. Although coverage may be lacking, i may just switch to an att ST sim.
To answer your question, a Tmobile S3 will work on ATT HSPA+ network with the HSPA+ Speeds of up to 6-7mbps in NYC area. The average I've been getting is around 2-3.5 mbps. With the tmobile prepay sim I have, it's usually around 2-18mbps down in NYC area.
The T-mobile S3 will not work on the ATT LTE network because it lacks that radio (or so they say for now); there have been other threads suspecting it's just a matter of flashing the right radio to "turn on" the ATT LTE radio. However, if all you want is HSPA+ speeds, rest assured it will work fine.
The ATT S3 is lacking the AWS bands for TMobile so it will not get the HSPA+ on Tmobile.
Best regards.

radio issue
First off, I would like to thank everyone who has been helping me along with my issues with my phone. I appreciate it a lot and I'm picking up more knowledge more and more everyday from you guys and reading heavily on the forums.
if the hardware in the phone doesn't support HSPA+ 1) will i have to root the phone and 2) change the radio? And 3 ) if I change the radio does that mean I would need to install a custom ROM i order for it to work properly?
Also, from one of the post they said "The T-Mobile S3 has the 850/1900 3G bands " - of that is true will than I should be able to have the 3G speeds correct?
I really hope I am not making some people angry, I'm new to this and trying my hardest to understand everything so I don't make mistakes. Please bare with me. Again, thank you so much everyone who has contributed so far. I still have a lot to learn. The reason why is because I just don't want it to work ( I do, want it to work ) but I want to understand why everything is working they way it is and I've over the past almost month have been picking up a lot of knowledge. Can't wait to hear from you guys

kmdub I believe your the one that's wrong.

No, actually, you are wrong. The T-Mobile S3 does not need any modification to work properly on AT&T's HSPA network. Seems you are confusing something else with frequency. Quit spreading bad information.
OP: Don't worry about it. Some are making this way more complicated than it needs to be. As said before, if you have the T999, you will be fine on AT&T's HSPA network without any modifications (other than an account...lol). Just get the phone SIM-unlocked, pop in the right SIM, you are good to go. Seriously, it is that easy.

Well there it is, I stand corrected!
I had no idea the T-Mobile SIII supports At&t HSPA+ bands.
Is the same true to all T-Mobile HSPA+ phones?

Sorry for any issues, just learning
Hi everyone,
thanks so much for the info. Will the S2 I needed to put in certain APN settings inorder to receive MMS ( picture ) via texts. Do i use the same settings for the Samsung Galaxy 3?

I too have learned from this thread

[Q] on AT&T, which carrier N4 should I get?

Well after the fiasco with owning an AT&T Note 3 and rooting, bootloader, etc. I'd like to not make the same mistake with the Note 4.
Which carrier Note 4 should I get for unmolested use on AT&T? Will the Verizon version have a sim card and LTE? Or is the Tmobile version better and does it have all the bands? I'm hoping either of them will have unlocked bootloader and also be unlocked from the carrier, and of course be rooted.

T-Mobile would be the one if you are going to get it from a carrier, however your best bet might be to get the factory unlocked version see link below.

****UPDATE**** 09/15/2014
It has been brought to my attention by another forum member that the international version of The Note 4 may not work properly with 4G Data. Please confirm before buying.

Sigh....that's getting pretty pricey for a phone. I've been planning on getting at TMO. Not sure what I'll end up doing, but not sure I'll be putting out 900 for a phone.

T-Mo is the only one you want to get for an AT&T plan.
Stay away from SPR, VZW and all International phones.
See my sig.

If you got 4 carrier where you live, I would choose T-mobile. Cause its SIM and thats the world and their prices are awsome! Why pay more?

AT&T and Verizon also use SIM cards... He may want to pay more because T-Mobile has crap rural coverage.

I don't think that the international version will support T's LTE frequencies? You will be limited to 3G on this version.

Very true on TMO coverage--that's why I "had' to move to ATT
Will wait and see if the TMO one runs well on ATT, in case I want to continue to flash roms--

I'm not seeing where Tmobile is really much cheaper. Comparing my plan, they are $10 cheaper total, for 2 lines. With the amount of reception I'd lose with them it's in no way worth $10/month. All this promotion that they do, when they just need to put all their money into their network.

It's not that T-Mobile's coverage is bad, its the fact that their signal goes about half as far as AT&T's if that. They also need more towers in an area to ensure good coverage. AT&T's 700/850 frequencies can travel a lot further than 1700/2100 and penetrate buildings much better.

I was hoping they improved from 18 months ago. Sounds like they haven't. I was half mile off I75 in a decent size town and couldn't make a business phone call. That was it for me. That was before tmo lte in my area, so maybe it is better. But, I have good lte and at least some some signal were ever I go. Not bashing anyone, it is what it is--
