3g in argentina please help!

hi, i have a brand new rhodium t-mobile version, flashed with the nrg rom feb 1st.
when i use the data connection the phone connects to the edge network, while the same sim card connects to 3g/H on a motorola milestone. i read on google that 2 or 3 users (the phone isn't sell in argentina) that have the same problem...
the 3g network in argentina works in the 1900/850 band, so i have it configured that way but it doesn't work.
does anyone knows how to solve this, please?
thanks in advance

3G with the T-Mobile version (RHOD210) works on the 1700/2100 MHz AWS spectrum. You will not be able to use 3G on your network with this device. There is no fix or work around. This is a hardware limitation.
EDIT: You should have gotten the Tilt2 (RHOD300). This is the AT&T branded version that has radio hardware which supports your network.

ok, last question, why in the band section it has the option to use 1900/850 Mhz?

that´s what i thought that it would work..

If it truly does support switching bands, as the link you posted would indicate:
http://support.t-mobile.com/doc/tm5...5611&navtypeid=6&pagetypeid=7&prevPageIndex=5
Then, I would recommend flashing the Stock ROM. Then see if you can get it to work with the stock T-Mobile ROM. If you can, then it probably is possible to do it using an Energy ROM as well. But, I don't think it is possible.
I am not that familiar with T-Mobile phones, since I use an AT&T Tilt 2. It seems unlikely that this would work, since in the United States even the T-Mobile HD2 doesn't get 3G when SIM unlocked and switched to use the AT&T network with an AT&T SIM.

That band switching feature is to set network preferences for your carrier outside of the US. The radio hardware does not support UMTS 3G. You will only be able to get EDGE speeds at best from this device on your carrier. You need the RHOD300 (Tilt2) to get 3G on your network.

that´s a bummer
thanks for your answers

[Q] Unable to use UMTS Mode (ONLY GSM WORKS )

Hi all
I just recently acquired a INC 2 Love the phone by the way and am located in INDIA
I'm running a r1 rom which offers full GSM functionality
SIM: TATA DOCOMO
The issue I have is
I can connect to GSM only Mode , but when I try GSM/UMTS or UMTS Only , the phone cannot cannect to a network.
The phone is SIM unlocked and in GSM only mode I can call/sms/data fine
My service provider uses the 2100 mhz band so obviously the INC 2 supports that, I have searched and lot and have tried various ROMS, but unable to narrow down a solution
i have tried the *#*#4636#*#* mode and even there only GSM ONLY works
NO GSM/UMTS , WCDMA or anything
Basically I cannot connect to 3G
Any suggestion guys

bump guys...... 98 views and not a soul to reply

Had the same problem, couldn't find a solution. Bump!

Have you try manually entering the APN (access point network) for your carrier? That might help.

Yes I have, pretty much tried everything.

yes the APN is the same for both GSM and 3G
It just wont connect to a 3G network... only works on force 2G ie GSM

That is kind of weird. Does Tata only uses 2100 mhz? Maybe try updating the radios? Does the stock rom also not picking up 3G?
I'll be traveling to Hong Kong in 2 weeks and there uses 2100 as well. Let me see if I can get 3G and will let you know. It's hard for me to test UMTS on my DINC2 here in US coz I could only get EDGE from TMobile or AT&T.

All Indian networks use 2100 ... Yes it did not work on stock either ... I'm wondering if band unlocking is needed ..

Free unlock method.

Edit: this method works for everyone it seems. SOME HAVE REPORTED SLOWER T-MOBILE DATA SPEEDS AFTER APLLYING THIS UNLOCK. This has only been reported a few times and it seems like flukes. I however, nor the OP in the linked thread are responsible for wjat YOU chose to do to your device. You have been warned.

What was the default value of "Perso SHA256 "....I changed mine to off but forgot to check the original value...original value should be in Perso SHA256 Flag info

Seemed to work with verizon sim. No longer get the input sim unlock number, but obviously no signal.

Phone wont even get GSM signal ? I thought this phone does support 1900 Mhz which verizon also uses.

It got a signal. But could not pick up carrier or anything just had signal and said searching in notification bar.
But verizon is CDMA so it did not supprise me.

I see that the LTE radio bands are in there, no surprise there. But I also see WCDMA radio bands too. Does that mean that our Galaxy Note 2 have WCDMA radio too? Or is this just an firmware that Samsung uses across all Galaxy Note 2 devices?

I need to try this I have a at&t sim card.

I think we have CDMA also....not that it does much for us as verizon and sprint require the imei to be loaded into their systems.
WCDMA != CDMA by the way. WCDMA is 3G/4G GSM (aka UMTS)
CDMA is a competitor to GSM. It is used by mainly North American and Japanese/Chinese cell phone companies.
I know Verizon and Sprint in the US and AU in Japan use CDMA. Most of the world uses GSM.

All though thinking about it while we may have the CDMA radio, assuming it is the same chip as the GSM and LTE radio then they may have just not sokdered the connections. Seen that before with FM radios built into the bluetooth chip on the Atrix 4G

Which of the bands are our 4G?
Love learning.

Our 4G is UMTS band 4 (1700/2100) same as our 3G. We dont have LTE yet so no *true* 4G

Sweet.
Thank you.

No problems. This kinda stuff is my hobby. Maybe some day I can get a job at a cell phone company as a technician or something.

I can confirm this works, but I could not get data. I got signal and a carrier name with both an AT&T sim and a Straight Talk (AT&T) sim. It would not load APNs, and I don't have the APN for regular AT&T so I tried with the Straight Talk, put in their APN and still got no data. Neither sim is active currently. It did allow me to call 611 on both sims.

If neither sim is active then I dont think it will allow data. Not sure though.

The same problem is getting me as well. According to the Network provider(WaridTel Pakistan) this model of HTC One M8 is not supported in Pakistan or Carrier Lock something even the LTE option is appearing in network modes. Meanwhile 3G and edge is working perfectly.

Issue connecting to 4G

So a mate has a P2 and can't seem to get it to connect to 4G. The SIM card and network is Vodafone UK.
What I know/have tried:
- SIM in both sim slots will connect to 3.5G (HSDPA) on Vodafone network
- A different SIM (Three UK) did connect to 4G in the SIM slot 1 (did not try SIM slot 2)
- Settings says 4G preferred network is selected
- By typing *#*#4636#*#* into dialer and going to phone info displays LTE is selected as one of the preferred networks
- The same SIM (Vodafone UK one) connects to 4G in his old phone and has done in all his old phones
- APN settings are correct, verified by Vodafone support plus myself looking online
So he talked to Vodafone support again today who said try speed tests in 3 different locations and report back. He has done 1 which is 14mbps down and 3mbps up which is slow for 4G (I get 64mbps down and 24mbps up, different network but shows his is slow and likely not 4G). Similarly we we know the device can connect to 4G from using the Three UK SIM.
My gut instinct is it's a network issue, all device settings seem okay, nothing is screaming out of place. The issue though is that the SIM has connected to 4G in his other devices so confuses me.
So, I'd love your thoughts and inputs on this. Any suggestions welcome that may help! Thanks!

I dont know the device or network specifically But I know that the device has to support the same lte bands that the carrier broadcasts in LTE in that area Just because the carrier broadcasts say 900mhtz in LTE, if the device dont support 900 in lte then it wont get it. I have had cases wher 3g is the same freq as 4g it still wont pick it up If you get what I am saying. May be a issue or not.

to further add he might take one of the old devices and use a signal catching app to see what lte bands are broadcasted in his area then compare to device

Thanks @TheMadScientist, all suggestions welcome still. I'm gunna continue to keep an eye on this, research answers and send him a link to this so he can test anything on the device.

We get this issue a lot using sprint phones unlocked international gsm. A lot of carriers seem to not use the same lte bands.
Then naturly verizon devices come gsm unlocked but verizons radios are crap and do not pick anything up half the time. My veriz g5 can get lte next town over cause they use a supported band and no towers near me use it. So i get 3g. And a lot of h h+ i ise lte discovery as the app on mine.
Just hope this isnt his issue as its a harware compatibility .

So I checked the network and the device (on GSM arena) and it seems 4G bands are supported. But I'll try that lte discovery app with him soon you mentioned and see what results that yields

@matt4321
http://www.techadvisor.co.uk/how-to...r-phone-is-supported-by-your-network-3597426/
You should check the manuals if there is support for 2600 frequency on phone.
Maybe the phone supports 800/1800(cos 3 is on 1800) and you don't have 800 band in area.
You will have to contact Lenovo and ask them to change baseband or whatever...
or Perhaps get a new phone with support for 2600

Had the same problem using a LG G3. I tried this App to trigger LTE only. Then the Phone connect to the LTE network.
