The best and cheapest 3g network in the USA?

Hello, I am going to visit USA in August for 1 month (many states), could you please advise me, which 3g network is cheapest for SMS (foreign SMS too) and 3g Internet (well, probably unlimited or best for Android heavy usage)
Thanks for attention
Read that AT&T has the best 3G coverage, but it's pretty expensive - 5 gb for $40, am I right?
P.S. Not sure if I chose correct place to post this thread
For no plan prepay you best bet is Tmobile. 3G coverage in almost all real cities. Edge in most small towns, and G everywhere else. I can get internet anywhere with it just slow internet if I'm in the middle of nowhere driving state to state. They have a data only plan for $38.99 a month unlimited(10GB). Or 500 anytime minutes free nights and weeksends, unlimited txt and unlimited data(10GB) for $59.99. If you go ATT you will have to run a credit check even to get 1 month of service and even then they don't have any data only plans so your bill will most likely be the 39.99 + $30 for 2GB data, + tax's which run around $10.
Thank you very much, in this case I'll take T-mobile unlimited data plan then
And maybe keeping second (old) phone with old sim card in roaming
Which plan do you think it is better to take for my sister if she doesn't use the internet at all and just SMS?
and are this unlimited SMS work if you send them abroad? I mean are they still free?

uh... just make sure that your phone supports Tmo's 3G bands (probably not)... 1700 AWS, not 2100 (i.e. UTMS 1700 not UTMS 2100)...
Yep, T-Mobile would be your best bet
Check out Simple Mobile.
They use T-mobile's network and offers $60 for everything INCLUDING unlimited international text message. If can get good T-mobile service in your area, you might as well sign up with them to save bunch. The only downside is you have to have a unlocked or T-mobile compatible GSM phone in advance as they don't provide subsidized phones.

Again... don't expect such phones to work with Tmo's 3G... you'll be stuck with EDGE...
You'll need the Samsung Vibrant if you want Tmo's 3G to work in the US... or a Behold II or MyTouch... plus Tmo has funky rules for Android phones on prepay (or not)... you may need to do their FlexPay ...
there's a good chance that you'll have to go with AT&T prepaid... given what you're planning...
Your Euro phones probably won't work with Tmo 3G but you very well might pick it up some places. Many many many people have picked up 3G on tmo's US network with INTL unlocked phones. One of the bands matches, the other doesn't. So it depends on which tower your near.

I believe what you say is incorrect. Not only are the frequencies around 2100Mhz different between Tmo's 1700/2100 (UTMS1700) and UTMS2100 different, but UTMS1700 *depends* on the 1700Mhz for uplink, so you can't even create a connection.
Actually...certain Asian phones operate on the same frequency bands as T-Mobile...but good luck getting your hands on one.

Confused
So, I am going to buy Samsung Captivate
It's UMTS 850/1900/2100
If I unlock it for any sim and put T-mobile sim inside, 3g won't work?
I should use AT&T then? I saw at the web site that there is a 5 gb data plan for $60
I don't really want to buy T-mobile Samsung Vibrant because it's easier for me to buy international version then, but I don't really like how it looks.
And just one more question, I am going to live in Singapore for 1 year soon, does anybody know if 3g will work with Captivate in Singapore?

This is correct. Tmo runs on a special band so only Tmo branded phones, and some "asian or INTL" phones can use tmo 3G. ATT 3G is US standard and can be used by most phones, but ATT doesn't have any unlimited dataplans anymore. They don't have any prepay dataplans, the only data only plans they offer are for the ipad. So your gonna pay much more, but ATT will give you better 3G coverage, but slower in the cities compared to TMO. TMO actually is beating out sprint 4G in most area's, but its coverage is spotty and only in large cities. I would go tmo and buy a throw away phone when you get here. Or get a tmo phone for the trip, then actually spend real money on a phone when you get home. You can get a TP2 for around $150-$200 here, and HD2 for $250, then you can ebay it off when you get home or sell it real quick on CL before you leave. If you haven't tried it the TMO HD2 is a beast.
well, I wanted to use tons of android apps using 3g internet, but in this case I should just use EDGE... don't want to buy special phone for 3g or something like that...
it seems that I have a choice between 3g with AT&T for $60 (5 gb) and T-mobile EDGE for $40 (unlimited data) ?

well you could get 100MB of data on AT&T for $20... but perhaps that isn't enough for you... seek out Wifi whenever possible? (that's what I do when traveling outside the US...)
or live with Tmo EDGE, which really isn't that bad and some would claim that you may be dealing with EDGE or EDGE-like bandwidth on AT&T as well, depending on where you go and congestion (hoards of iphone users)...

Is there any GSM choice except AT&T & T-Mobile?

Is there any GSM/WCDMA mobile telecom carriers besides AT&T and T-Mobile?
Verizon, Sprint, Virgin Mobile, Cricket, Straight Talk... They are all CDMA/CDMA2000... But I do not want to throw away my Samsung Galaxy S phone, which worth nearly $500 and only supports GSM/WCDMA network. I really wan to get rid of AT&T, so does T-Mobile

At&t and T-Mobile HSPA+ can run same device?

I know how At&t are gonna have HSPA+ 4g, I'm confused about the new devices they're gonna have that support HSPA+. Are they going to be able to connect to HSPA+ on T-Mobile's network.
So for example, I buy an unlocked HSPA+ tablet from AT&T, straight from their store. Is it going to be able to use T-Mobile's HSPA+ network if I put a T-Mobile SIM card inside?
Also, one last question, if I use T-Mobile's SIM card, do I have to do some special stuff to get it to work on their cell network? Like how you have to unlock an iPhone for it to work on T-Mobile?
Thanks

Hello,
Unfortunately you will not be able to use HSPA+. HSPA+ is just an extension/revision of the current 3G. Effectively it is also called 3.5G/3.75G in some reports. They use the same 3G band of each respective company. The At&t tablet would work on 850/1900 band and T-mobile will work on their AWS (1700) band. So if you bought an At&t tablet, you may need to get it unlocked, not sure if they lock the sim on tablets. At best you would get Edge service with a T-mobile sim.
thanks man, argg
do you think it's worth it to change to at&t because I just heard of the Motorola Atrix and it sound PRETTY BAD ASS!
I don't know since people I know are always angry at AT&T for their service either..

NP. I have had every major carrier offered in the US. I have had at&t, t-mobile, and sprint within the last year. I had verizon a while ago and dropped them because they could never get my bill right. Honestly, the service is about the same. The question is how is the service in your area. I mainly stay in my area about 90-98% of the time. I live in a major city so all carries have great service. But I have stayed with At&t for the last few years. Every time I go to another carrier I kept my at&t service, go figure. So I would just look at coverage to where you travel the most and go with a carrier that will give you the best coverage for the best price. Do i prefer a carrier over another, yeah. I like GSM carriers better because I do like to surf and talk at the same time. Sprint can do this if your in a 4G coverage area and have a 4G phone. Verizon is a no go with this feature until they release their LTE phones. But At&t has a better coverage footprint than T-mobile that is why I stick with them. Hope it helps.
Wondering a bit about this too.
I have service through Bendbroadband using a HSPA+ SIM with USB modem Dongle by bandluxe. The service is stellar on the speed, but I can't use the dongle with everything (iPad), so looking for alternate routes before i decide to move to a different provider.
I noticed that the CTO of the company said in a comment regarding their service that any unlocked UE that supports HSPA/HSPA+ in the AWS band could be used, but also had an unclear reponse on cell phones with HSPA+.
I have a Huawei Comet (unlocked), it lists the same AWS Bands compatible, but says HSDPA (which I thought HSDPA + HSUPA = HSPA+ but at higher speeds, correct me if I am wrong), and has hotspot tether that works with tmobile web service no problem.
I plugged the SIM in, and it updates the bar with BendBroadband but I get no data. (might need to provide the IMEI or something)..
Curious if you think it should work, before i go knocking on their doors.
Some other specs:
the mytouch 4g (HSPA+) lists the bands as:850 MHz;900 MHz;1800 MHz;1900 MHz;UMTS: Band IV (1700/2100)
The comet is listed as: 850 MHz;900 MHz;1800 MHz;1900 MHz;UMTS: Band I (2100);UMTS: Band IV (1700/2100)
I am fairly sure the comet is HSPA+ but not advertised that way.
According to comments on the site, Bendbroadband technicians do not actually support moving of the SIMs. Bummer.. trying to keep my business local.. Bumping and moving to Tmobile once the month is up.

[Q] Will these Sprint phones work on Verizon?

I'm sick of my Sprint service dropping calls and would like to switch to Verizon. I can stomach the ETF, but new phones aren't in the budget for now. I have a Motorola XPRT and an HTC Evo 4G. Can these be activated on Verizon's 3G network? Would I need to root / install CyanogenMod? 4G isn't a priority.
Thanks!
Verizon won't enter the ESN into their billing system. You could get a prepaid from verizon then use CDMA workshop to copy the settings to your Xpert BUT cdma workshop will cost you 108 bucks.
you MIGHT be able to use the EVO 4G but you will not get EVDO data to work from what I have been reading.

Captivate now works with T-Mobile 3G (in selected area?)

I guess some people might already know this, but I want to mention it anyway in case .... someone wants to save money by switching T-Mobile.
I am in Miami area. I bought a Captivate for my brother a while back and unlocked it. He visited today so I tried on my T-Mobile Sim card and it works with AT&T HSPA with no problem. The device is running SlimBean 2.9 with no baseband changes. No data roaming enabled.
I guess this is due to the 1900mhz band that T-Mobile leased from AT&T after the failed buy out. I don't know specifically what other area 1900mhz are available. I remembered earlier this year I had an international Galaxy S3 and it only got EDGE on T-Mobile, so this has been a recent development.
It appears to be in limited areas: http://www.androidcentral.com/t-mobile-improving-coverage-lighting-1900mhz-10-metro-areas
They are re-farming their 1900Mhz spectrum to make it HSPA+. Right now it's just a few metros, but it is expanding and will continue to roll out for a while. Any AT&T smartphone that otherwise lacks T-Mobile's previous flavor of radios can take advantage of it, but T-Mobile is mostly aiming this at iPhone users who want to jump from AT&T and Verizon (the Verizon iPhone 5 is GSM unlocked).
Sent from my Nexus 4
just tested my unlocked cappy on t-mobile in seattle...
and got the fastest network speeds i've seen on this phone: 6.02 Mbps down / 3.43 Mbps up. This is on t-mobile's 1900 band refarmed to the HSPA network. I understand that the cappy will max out around 8 Mbps down/up, but I've never seen anything close to this on ATT's network.
I'll be moving over to the $30 t-mobile plan with 5 gb data next week when my contract expires. Ahhhh freedom.
