Hi, I wonder about that part of the smartphone is responsible for last frequency waves lte. I bought a phone that does not receive lte on Polish frequencies and I wonder if going to change any of the components to fit lte wave reception. Responsible for this is the antenna, chipset, or what? I hope for a response. THX

Greetings, can anyone please tell me if there is any way to get my T-mobile device to recognize other GSM frequencies? It is currently a dual-band pocket pc device and I would like to make it such that it recognizes the 850 Cyngular frequency in the US. In other words, how can I make my dual-band device a quad or tri-band device?

Hmm. i would say only by soldering. It's a hardware limitation of the device...

The MDA/XDA II device is already tri-band.
or did I missunderstand you?
greets Alex

That's right. But the MDA/XDA I is only a dual band phone.....

Yeah, my device is only dual band. I thought that perhaps all these devices initially had the potential or ability to pick up any signal but that it was a software issue to actually start doing so. I am not too good with the techy lingo, but is there something called "soft phone"? I can't imagine companies manufacturing very similar phones overseas and in the US and the only difference being that one is dual band and the other tri band. It makes sense that these devices are all quad band and the company places limitations on them depending on where they are purchased
no the HF VHF and UHF and so forth need a frontend which cant just be programmed like that it have to do with filters and such as in before the signal ever get close to being digital and programmable
GSM BAND SWITCHING SOFTWARE
DOES ANY ONE KNOW WHERE CAN I GET A HOLD OF THIS? THANKS
hi Rudegar
can you shed a little more light on the filters and hardware change that would be required to change a frequency or activate another if the chip has it. ( sometimes it is capable but not activated )
Hey guys!
I want to know if some tried, or thinks is possible, to overclock the LTE antenna on the VZW Galaxy Nexus.
I know their LTE works at 700 MHz, which no other damn place in the world uses. However in Brazil they have a GSM carrier working at 850 MHz and LTE is back compatible with GSM. So what I wanted to try is overclock the antenna so it would be able to work in Brazil. That seems possible because the frequency of the antenna is no limited by the hardware, it is programmed in some way.
So anyone with more knowledge can tell if that can work? We are able to overclock the processor trough ROMs, so there's must be a way to overclock the antenna. Maybe trying to use a GSM radio for the cellphone LTE radio?
Thanks!

Hi there,
My country cell provider, recently upgraded their connection to LTE. Their LTE frequency are said to be running on 900 Mhz Frequency
I bought my LG G3 in korea, so obviously my LG G3 is a korean version. LG G3 Cat.6 or the model is F460
I've changed my sim card to LTE sim, and my mobile connection are set to LTE preferred. However till these days still I haven't seen any 4G or LTE sign on my connection. I know not all the areas are covered, however even though I'm in the area where it's already LTE, I don't seems to getting the signal. I don't know is it because my mobile doesn't support the frequency here or other reasons maybe to explain it?
I'm having a hard time looking at the information if LG G3 F460 actually support LTE at 900mhz frequency?
It's running smoothly on a 3G currently.
FYI : It always shows 3G even though its actually running on 3.5G. However my friend said its just the display, while actually its already running the 3.5G Connection. I don't know if its the case with the 4G as well
I can't post the link to the specs here., because I still have post under 10. Maybe anyone can help me?
Thanks before
Mostly Network operator tell u if you 4G phone is compatible with their frequency or not thats the authentic way to know.

Hi, we are facing problems with the LG G3 D855 international trying to open band 4 (1700/2100) to use it in Argentina (here the telcos sell a G3 called D855AR).
We opened the band (trhu the method with QPST/QXDM software), it gets connected in 4G but the upload / download speed is very very poor.
Anybody knows if there a hardware limitation in that model that impact on the band 4?
Anybody knows if there other settings in the NV that could be associated with the lte bands?
I will appreciate very much any tip or advice.
Regards. Diego
Hi, i have a big problem with my LG G3 bought on january of this year. the version is the D855, italian warranty (as i am italian). from the moment which i put my SIM into the cell phone i noticed that it doesn't connect to 4G network (as just it found a 4G connectivity it started to search another network till it'd have found a 3G/H+ connectivity), delivered twice to the customer service (so i staied two months without mobile), LG wasn't able to solve the issue said that their test on the network was all right, now i found the only one provider that works with my device (i'm talking about H3G, before,when i bought it, i had Vodafone, but i have tried Wind and Tim though), but now i want to change it because it costs an arm and a leg, and i want to solve this problem by myself (as LG do nothing to solve it) and it seems there is no one with my same issue in the world wide, so what it would be a probably solution??? ask for other infos if you need!!!

If LG found nothing wrong with your device, and and only one operator has 4G working on that phone, it means that your phone doesn't support the bands other carriers are offering.
LTE bands for this phone (855) are 700 Mhz,800 Mhz, 900Mhz, 1800 Mhz, 2100Mhz, 2300 Mhz and 2600 Mhz.
Also, worth noticing is that the coverage differs from carrier to carrier.

i don't think that the problem is that, here are the LTE bands of the main italian carriers (included H3G):
-Telecom Italia: 800 MHz, 1800 MHz, 2600 MHz;
-Vodafone Italia: 800 MHz, 1800 MHz, 2600 MHz;
-Wind Telecomunicazioni: 800 MHz, 2600 MHz;
-H3G (3 Italia): 1800 MHz, 2600 MHz.
i have tried each one of these but the only one that works is H3G indeed and besides is the only one that doesn't own the 800 MHz band, so maybe the problem is that my mobile is not able to connect on this band (although it is available as you mentioned in your specs ). so is there a solution? p.s. on my old G2 work all four of them so it is undeniable that my G3 has a problem, i want just know if this problem is resolvable by myself and how!
whatever thank you for the help
