[Q]Changing 3g Bands

Hi,
i live in argentina, and i found i dont have 3g coverage.
bands in argentina are http://www.mobileworldlive.com/maps/network.php?cid=3206&cname=Argentina
Do anyone know if is there a way to config my xt720 to bands 850/1900?
tks!

There isn't anything to configure. The phone automatically defaults to the 850/1900 bands when 3G isn't available.

but if in my country bands ar 850/1900, why do i only have edge?

You probably won't ever get 3G due to different bands on the phone versus your country's. Edge only.

To expand on what the Rev said from what i know in North America all XT720s that were sold, were W-CDMA/AWS i.e. their 3G bands were 1700mhz down link and 2100mhz uplink. Although they did have quad band 2G i.e. GSM 850/900/1800/1900.
So if in Argentina they are using 3G frequencies 850mhz down link 1900mhz uplink then the xt720 will never get 3G HSPA, phones from the following carriers will work Telstra NextG phones (Australian), Rogers (Canadian), Bell New 3G (Canadian), Telus New 3G (Canadian), and AT&T (USA).
Hope this helps.

Will 3g work with ATT

THis question becoz galaxsy s2 released in UK has the band for the 3g network with USA.
Does anyone know if sensation has the 850/1900 band for 3g with ATT ?

No, it'll only get EDGE on AT&T. Voice will be fine however.

[Q] Does The Phone Support AT&T Bands

So does anyone know if this thing support AT&T 3G bands? If not, is it like the G2x and capable of it but just disabled in the baseband
Daru

Nope, its strictly T-mo. You'll get 2g on ATT.
The only phones I know that can go 3g everywhere are Nokia phones. I love their build quality but Symbian SUCKS!

your model will not work at all on T-mobile LTE (which needs band 2, 4, 12)
your model will only get 3G in refarmed 1900mhz areas
your model will get 2G/ EDGE
you should return/sell that model, and get another model (wait for D6616 official model with band 12 / wifi callin gsupport), or get D6603/D6633/D6643

just ordered G955FD and have a question

i didnt notice i had ordered the g955fd until a day after and im wondering since i live in the usa if im going to be able to use my carrier on this device. i use metropcs and live in a semi-rural area in georgia. i spend a lot of time in the city aswell. any info would be greatly appreciated.

MetroPCS is a US prepaid wireless service offered by T-Mobile US. MetroPCS uses T-Mobile US's GSM (1900MHz), a combination of UMTS/HSPA+(850MHz/1900MHz) and their 4G LTE networks.
For UMTS (3G) MetroPCS works on bands 2 and 4. UMTS B2(1900 PCS) and B4(1700/2100 AWS 1).
For LTE (4G) MetroPCS works on bands 2, 4, 12, 66 and 71. LTE B2(1900 PCS), B4(1700/2100 AWS 1), B12(700 ac), B66(1700/2100) and B71(600).
Samsung Galaxy S8+ G955FD supports all these UMTS/LTE bands except the B71(600) band. Usually GSM operators use higher frequency bands like the 2100/1900 MHz bands and rarely they use the lower frequency bands like the 700/600 MHz bands. So your G955FD will work flawlessly on 3G/4G MetroPCS network.
You can use LTE Discovery app from Google play store to check your band online while using your mobile. You get the band number on the Notification bar real time.

Thank you for this very detailed post! I do have one more question though. Do I need to flash any CSC? It seems like I was getting much better connection on my Nexus 6P than I am on this phone right now.
I'm running Renovate ICE 14.1 right now and I'm wondering if its possible to flash Snapdragon CSC on Exynos variants. I have tried it before on completely stock rom with no luck, but I have seen people say its okay to flash Snapdragon CSC on the Exynos variant of this device. Once again I really appreciate all this information <3
