Using just one 3G frequency? - Networking

Hi, Im planning to buy an LG Optimus L7 II Dual P715, which is listed as having the following 3g frequencies: HSDPA 850 / 1900 / 2100
The issue is that I live in Argentina and I think that we have the following freqs: UMTS 850, UMTS 1900.
I know that this sounds like a model specific, but my real question is if just having one of the required frequencies (850) should work fine here? Im from IT, but I do not know nothing from networks, cell radio frequencies, etc. Ive searched the forum for similar questions and couldnt find anything either.
If there is someone knowledgeable from here, Im planning to use the phone dual sim capabilities with Personal and Movistar.
Thanks!
Ariel

just a small clarification, the cell phone that I intend to buy has the following frequencies: HSDPA 900 / 1900 / 2100
And here in Argentina we have: UMTS 850, UMTS 1900.
So the only frequency that I would be able to use would be: 1900, would this be enough?
Thanks.

It depends on which company you have your phone and where you live. (UMTS = 3G // HSDPA = H (3,5G)
for example
3G BANDS IN ARGENTINA:
AMBA:
- Personal: 850 y 1900 MHz.
- Movistar: 850 MHz.
- Claro: 1900 MHz.
NORTE:
- Claro: 850 y 1900 MHz.
- Movistar: 1900 MHz.
- Personal: 850 y 1900 MHz.
SUR:
- Claro: 850 y 1900 MHz.
- Movistar: 850 y 1900 MHz.
- Personal: 1900 MHz.
good luck

ok, thanks for the reply... so it wont work, I live in AMBA and will use it with Personal + Movistar.
THanks!

It depends on a few things. If the carrier uses one frequency for upstream data and one frequency for downstream data, it won't work. But even if you can only use 1900 MHz, you'll be without data in areas that use only 850 MHz.

3g bandsof htc touch 3g

Hi,
only 900 and 2100 Mhz are listed in the technical details sheet of htc as possible 3g frequencies. However, I can not choose 900 Mhz but only 800, 850,1900 and 2100 Mhz. Could somebody confirm this and maybe check 3g in the usa?
Regards,

Tmobile compatible phone question

So I am keeping my Nexus 4, however I am in the market for a a phone for my wife. It has to work with T-Mobile and I would love to find her a HSPA+ compatible phone, however i am really confused on how to figure this out.
For example I am looking at this phone at GSMArena:
Sony Xperia T and they say these are the bandz:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1700 / 1900 / 2100
How do I know it will work with T-Mobile's HSPA+?
Any help will be appreciated.

Thanks bud, but that doesnt answer my question, I dont need to know what coverage is in my area, but more what phone is capable of using T-Mobile's HSPA+
Yes it will. T-Mobile used 1700 and 2100 for HSDPA.

Thanks EL Daddy! So if a phone lists those bands 1700/2100 that means it'll work with HSPA?
I ask because I am also looking at this phone the Xperia S and those bands are :
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1900 / 2100 - LT26i

That one will probably not work as I believe you need both the 1700 & 2100 to work ( up & downlink connection).

3G or UMTS is as follows;
2100 refers to Band I / IMT and is used in Europe and Asia
1900 refers to Band II / PCS and is used by AT&T in cities, and by T-Mobile (1900 migration).
1700 refers to Band IV / AWS and is used by T-Mobile (most HSPA service is still here).
850 refers to Band V / CLR and is used by AT&T in rural areas.
http://en.wikipedia.org/wiki/UMTS_frequency_bands
T-Mobile is slowly moving HSPA from 1700 to 1900 to support unlocked iPhones and free up 1700 for LTE deployment.
I would look for a phone that supports both (1700 now, 1900 future) or it may have a short life span.

Awesome! I see now, so in order for the phone to work on HSPA it needs both 1700/2100 bandz. AAHHHHHH SWEET! Thanks guys I made sure to hit the thanks button on both of you!

Nexus 4 works great on T-mobiles HSPA+ . I regularly get 20.8 mbps down/2.5 mbps up.. and this is in a 1700/2100 mhz AWS area .. PDX area has not been refarmed to 1900mhz yet - and Nexus 4 supports both 1900 mhz HSPA+ and AWS HSPA+ - so no worries.

Just to clear up one thing. T-Mobile often refers to 2100 as the Download Frequency of AWS (Band IV), while most hardware manufactures reference 2100 as IMT (Band I). See column 2 in the wikipedia link I posted earlier.
I get both bands here in NYC (mostly AWS) and the speed is about the same on both (20 Mbps / 2.5 Mbps), but ping results are quite a bit lower on PCS.

T-Mobile Dropped My Spectrum?

I'm currently using a Samsung Galaxy S4 I9505 International (GSM card)
I'm now getting data speeds of 0.13 Bps. That can't continue.
I'm When I spoke to T-Mobile support they told me that the 1900 Mhz spectrum (LTE) is being dropped for the new 600 Mhz spectrum. This is for 5G. They advised me to get a phone that has 600 Mhz (phones not available yet) and 2100 Mhz spectrum. In the data below you can see that my phone can use 1900 Mhz for 2G and 3G. This is a mess. Apparently the 1900 Mhz my phone used to use (and provided quite good data speeds) has already been dropped, but the 600 Mhz I will need is not yet in phones currently being sold. What do you recommend I do?
The changes are related to T-Mobile aquiring new frequencies so they can improve service and data speeds. This implies that T-Mobile dropped a frequency which my phone used (1900 Mhz?), and which used to give me quite good data speeds.
So my slow data speeds are the result of changes made by T-Mobile. I brought my own phone, and did not purchase from T-Mobile, so they didn't offer me a new phone cheap.
My research shows me that my area has 700 Mhz LTE. But apparently my phone can't use that.

2G: 850, 900, 1800, 1900 MHz, GSM / GPRS / EDGE
3G: 850, 900, 1900, 2100 MHz, UMTS / HSPA+
4G: 800, 850, 900, 1800, 2100, 2600 MHz
Get a device that uses US LTE bands. Your only other option is to risk bricking your S4 to add US bands to its radio chip.
