Hello all. I've just got LGOG recently. Everything seems to work fine except I can't get HSDPA or 3G with this phone. With Nexus 4 and my current sim, I can get HSDPA and/or 3G in the same area. I use the same apn setting but I can only get Edge on my OG.
What I have tried:
- Got to the service [email protected] Only and change Network mode to WCDMA 1900 >>> didn't work. Shows only EDGE.
- Service [email protected] Only then RAT selection and change to WCDMA only >>>> phone won't get any signal.
I would be appreciated if anyone can shred some lights. I was about to sell my Nexus 4 but I have to think again if I can't even get 3G with OG in my area. Thanks!!!
What carrier are you on?

I am using Walmart family mobile. The APN is set to use epc.tmobile.com in Nexus 4. I tried the same thing in LGOG but I have no luck.
Not sure what's wrong with your phone. I switch between my nexus 4 & og when the batteries die, and data always work.

Is it about the 1700/2100 frequency that OG uses for LTE ? I took my friend's AT$T sim card and put in my OG. The 4G works fine.
Ace42: I saw your post about flashing OG radio to N4 radio. Will the flash mod the radio of OG to be exactly the same as what N4 has? For example, will it change from:
GSM: 850, 900, 1800, 1900 MHz
UMTS: 850, 1900, 2100 MHz
FDD LTE: 700 (band 17), 1700/2100 (band 4) MHz
to:
GSM: 850, 900, 1800, 1900 MHz
UMTS: 850, 900, 1700/2100, 1900, 2100 MHz
If so, I would like to try it out but is the mod reversible ? I am pretty new about this so please excuse met if I might ask some stupid questions. Thank you so much.

The radio bands are hardware dependent, you will not get additional bands from a radio. It is just the att modems may give no mic or speaker audio on T-Mobile and its MVNOs.

Thanks for the clarification. I actually tried to flash the phone last night and it doesn't work. I think I will just need to wait for T-Mobile to refarm this area then.

They mostly rearmed major cities, there's a service map that shows how very few areas have rearmed 1900.

I would love to be able to use this amazing phone in on T-Mobile in the US without crippled data speeds as well as seamlessly on voice. Anybody here have experience with this new phone on this network?
ST18a is supposed to be for AT&T, but I speculate that ST18i might be better for T-Mobile US due to 900/2100MHz. 1700MHz is missing though. I also don't know how accurate this is:
hxxp://en.wikipedia.org/wiki/T-Mobile_USA#Radio_frequency_spectrum_chart
Just today a T-Mobile Tier2 told me all I needed was 900 / 1800 / 1900MHz for 3G, and 1700 and 2100 for 4G.... so I am left very confused.
Note even access to 3G via roaming on this phone would be acceptable.
just to relieve you from misunderstanding, the ray is not 4G, and the bandwidth 2100 is 3G, and is used mostly in europe and asia pacific, which ever version you get, the umts is available in 5 bandwidth and are all 3G
Hi kms108,
What's your experience with the ST18i? Are you using it in the US? Possibly on T-Mobile?
Thanks!
i have the hong kong version, which is unbranded and using it in hong kong.
i'm liking it very well, just the right size to hold, not a android phone on the market to match it in quality, specs and size wise.
Xperia ray DOES NOT support 3G from Tmobile.
I own the device and I learned it the hard way.
Although ray supports 2100 MHz, the only device that can access Tmobile 3G is the one with BOTH 1700/2100 MHz. It is because Tmobile split both frequencies: one for download and the other for upload.
While for other carriers your phone will work in 3G if it supports either one of the frequencies, however, Tmobile is different.
Having said that, almost ALL of the unlocked phones in the market won't be capable of accessing Tmobile 3G.
If you wish to access 3G, the only carrier that will work is AT&T.

Which version, ST18a or ST18i, did you buy? See following:
hxxp://androidforums.com/sony-ericsson-xperia-ray/443709-3g-4g-us-t-mobile-using-st18a-st18i.html
Mine is the ST18i.
Well, neither version will support Tmobile 3G.
ST18i UMTS HSPA 900 (Band VIII), 2100 (Band I)
GSM GPRS/EDGE 850, 900, 1800, 1900
ST18a UMTS HSPA 800(Band VI), 850 (Band V), 1900 (Band II),
2100 (Band I)
GSM GPRS/EDGE 850, 900, 1800, 1900
Here's the specs from the manual.
Since both are missing 1700, neither will be capable of receiving 3G from Tmobile.
AT&T
What irony -- maybe the AT&T acquisition of T-Mobile will have some benefits after all, especially those who buy the ST18a...
This wikipedia link confirms your experience: hxxp://en.wikipedia.org/wiki/T-Mobile_USA#3G_upgrade
The Xperia X10 had 1700, too bad Sony eliminated it.

I have the HTC Radar 4G on T-Mobile. Once I unlock it and use it on At&T, it will definitely do calls, but will it pick up 3G or 4G on the AT&T network? I asked HTC and they were unsure. Thanks!
Do a search in this forum to find your answer.
Sent from my Titan using XDA Windows Phone 7 App
AT&T uses 850 MHz / 1900 MHz for GSM/GPRS/EDGE and the same two frequencies (850 / 1900) for UMTS/HSPA (their 3G/4G service).
T-Mobile uses the same frequencies (850 / 1900) for GSM/GPRS/EDGE, but uses 2100 MHz and 1700 MHz for UMTS/HSPA/AWS (their 3G / 4G network).
If you want to know what phones will work where, compare the frequencies they receive with those of the carrier you want to use.
In the case of the Radar, it uses the following frequencies
GSM/GPRS/EDGE: 850 MHz; 900 MHz; 1800 MHz; 1900 MHz
UMTS/HSPA: 1700 MHz; 2100 MHz
So, for GSM phone calls and data you have a match with AT&T (and, of course with T-Mobile). 3G / 4G is a different story. The Radar has the T-Mobile 3G/4g bands, but not the bands for high-speed data on AT&T.
So, if you are happy just making phone calls and using EDGE data, then you can use the phone on AT&T. If you want 3G /4G as well you have to stick with T-Mobile.
bleh bleh +10
I finally was able to get the h2O SIM card (AT&T service) and surprisingly it picks up 3G! I definitely notice the difference from when it goes from 2G up to the 3G speeds
http://www.htc.com/us/products/radar4g-tmobile?view=1-1&sort=0#tech-specs
Apparently. It says it does 2100/1900/1700/850
*T-Mobile only uses 1700/1900 bands. source
Interesting! I took my specs from the T-Mobile page which omits the UMTS 850/1900 band. Thanks for the correction.
The box clearly states GSM 850/900/1900/2100 AND HSPA/UMTS: 1700/1900/2100
AWS 1700 = T-Mobile, Wind, Mobilicity
UMTS 1900 = AT&T (although they use 850 extensively too), Rogers, Telus, etc
UMTS 2100 = Asia/Europe
My Radar picks up AT&T 3G. Not sure if UMTS 1900 band will be omnipresent on AT&T as a lot have been extended with HSPA 850 as well.
So, whereever you find UMTS 1900, you'll definitely catch AT&T 3G
Hope this helps.
So, will this work with the medianet plan?

The U20i supports gsm (2g) on 850, 900, 1800 and 1900
and HSDPA (3g) on 850. 1900 and 2100 by default...

You're right... I accidentally listed the networks for the U20a...
The two types were sold in different regions. (or by different providers, dependant on which frequencies they used), but there is no way to make it work on other frequencies... it's a hardware issue as far as I'm aware.
As we all know, every device has 2 variants based on regions. The Xperia Z2 has it as well.
- the D6503 I believe is the Rest of the world
- the D6543 I believe is the NA version
- D6502 could be the Non-LTE
So as I was researching about specs I found this in GSMArena website.
2G Network
GSM 850 / 900 / 1800 / 1900 - D6502, D6503, D6543
3G Network
HSDPA 850/ 900 / 1700 / 1900 / 2100 - D6502, D6503, D6543
4G Network
LTE 700/800/850/900/1700/1800/1900/2100/2600 - D6503
LTE 850 / 900 / 1700 / 1800 / 1900 / 2100 / 2600 - D6543
I live in Asia and fly to Canada every year and I find it a hassle bringing 2 phones. The frequency bands of Z2 intrigue me.
My asian network uses 1900/2100 FOR 3G and LTE 850/1800/2100
My Canadian network (Wind) uses 1700/2100 , they have no LTE network yet
So does this mean both D6503 AND D6543 versions are compatible either networks? It sucks using 2 phones when 1 is not working with the network. (I use the S4 to take pictures. Nexus 5 camera is not so good in my opinion)
It looks like they are compatible.
You find the specs in the whitepaper
D6503 UMTS HSPA+ 850 (Band V), 900 (Band VIII), 1700 (Band IV),
1900 (Band II), 2100 (Band I) MHz
GSM GPRS/EDGE 850, 900, 1800, 1900 MHz
LTE (Bands 1, 2, 3, 4, 5, 7, 8, 13, 17, 20)
D6502 UMTS HSPA+ 850 (Band V), 900 (Band VIII), 1700 (Band IV),
1900 (Band II), 2100 (Band I) MHz
GSM GPRS/EDGE 850, 900, 1800, 1900 MHz
D6543 UMTS HSPA+ 850 (Band V), 900 (Band VIII), 1700 (Band IV),
1900 (Band II), 2100 (Band I) MHz
GSM GPRS/EDGE 850, 900, 1800, 1900 MHz
LTE (Bands 1, 2, 3, 4, 5, 7, 8)

It seems weird to me that the 6543 would be missing some LTE bands and yet add none. I wonder why/how that would be. Do they actually have a different modem chip with fewer radios in it? It seems like that would be more work than just supporting the same bands on both even if some went unused on the 6543. If there's not a huge price difference it seems like you'd definitely want the 6503 just for the increased band support.
Hmm interesting. D6503 is 99% similar to D6543 except it has more frequency bands. Would definitely get the first one. I wonder why Samsung doesnt make phones with multi-bands, especially for "international i9505" version.
Thanks for the replies! Ive hit thanks! Hopefully my seller knows what version he has.
Im from Canada...I would just switch to rogers or bell when your here..then you only need to bring one device since mhz is the same as in asia I believe (im in manila right now ...and loving it...with a rogers device and have no issues on smart...LTE included..slow as hell but working lol).
Besides..wind sucks anyways lol!
sent from vacation in the phillipines via i337M galaxy S4
And Im back to Canada once again, sorry to necro the thread. I just called Wind, and they confirmed my phone Xperia Z2 (model D6503) works with their network. So now, i just have to unlock my phone, just $20.
Hi, last week I was given a Moto G3 XT 1541 from Spain. The problem is that it doesn't connect to argentinian carrier's 3g or 4g bands, it only works on 2g. A friend told me that I could work it out flashing the firmware of another model like XT1540 which works perfectly on 3g and 4g. Is it a firmware block? Can I solve it flashing another model's firmware? If I flash it, will my phone work or it will be a stone? Thank you ver much.
Yes, you can.
Moto G 3rd generation does not have capability of 2300 MHz bandwidth.
Requirements for a4G
1. A handset that supports 2300Mhz.
2. A 3G plan.
3. USIM (they provide free upgrade)
4. 4G network coverage
I think even HSPA or HSPA+ might not work for me on this phone. I am using a T Mobile family plan here, and comparing th bands given on the website:
"4G (HSPA+)
With 4G, theoretical maximum download speeds range from 21 Mbps up to 42 Mbps. You can take advantage of incredibly fast download speeds, and even use voice and data services at the same time.
Frequencies: Band 2 (1900 MHz), Band 4 (1700/2100 MHz)
3G (HSPA)
With 3G, theoretical maximum download of 14 Mbps. With 3G, you can use voice and data services simultaneously.
Frequencies: Band 4 (1700/2100 MHz)"
"Moto G (XT1550)
LTE (1, 3, 7, 8, 28,40) UMTS/HSPA+ (900, 2100, 850 MHz)
GSM/GPRS/EDGE (850, 900, 1800, 1900 MHz)"
It seems that the uplink is unsupported by my phone and so the phone is unable to use the HSPA/HSPA+ bands. I think the only way to use it is to unlock the 1700 MHz band on my phone.
XT1541: GSM/GPRS/EDGE: 850, 900, 1800, 1900 - UMTS/HSPA+: 900, 2100 - LTE: B1 (2100), B3 (1800), B7 (2600), B8 (900), B20 (800)
Argentina UMS/HSPA+ works on 850 and 1900.
This phone will only get 2g where you are. Flashing another firmware will not fix this.
