Why we are having issues with signal...

Got bored and did some research...baked into the software is the bandwidths across the holiday and carriers specific phones...since we are not able to flash radios...this is becoming an issue for a lot of people....so heres what I found thought was interesting...these are controlled by the radios which for now we are not able to flash so until we are able to flash,signal issues will be a factor...

Telstra Bandwidths
Telstra will sell dual mode LTE/HSPA+ mobile broadband devices that will operate seamlessly across 1800MHz and 850MHz spectrum bands, giving Telstra Next G network customers the benefits of 4G where it is available and then seamless switchover to the 3GHSPA technology in other areas.

No issues, You just have to modify a few files in any SKT or AU based rom.
Battery drain though.... That is another issue & will continue until we get a solid custom Vivid based Kernel that uses Vivid voltages instead of using the Raider Voltages, which as you know, uses a different processor than the Vivid.

Rogers raiders is the same as at&t vivid. The raider in Korea runs differently. Right now we are using 1700/2100 for lte service until the 700 auction can be completed. Then we will use 700 band.

Which is the best model fo rthe T series?

Correct me if I am wrong but after searching I think the below is what I know:
Xperia T : Work for Tmobile and AT&T 3G only..
Also known as Sony LT30p
General 2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1700 / 1900 / 2100
Xperia TL: work for 3G tmobile and 3G/LTE for AT&T?
as Sony LT30a.
General 2G Network GSM 850 / 900 / 1800 / 1900
HSDPA 850 / 1700 / 1900 / 2100 - LT30a
LTE 700 / 850 / 1700 / 1900 / 2100 - LT30a
Xperia TL: for AT&T phone and only E for tmobile?
Available as Sony Xperia TL LT30at (AT&T).
General 2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 1900 / 2100 - LT30at
4G Network LTE 700 MHz Class 17 / 1700 / 2100 - LT30at
So the best phone would be TL30a > Because it will work with 3G tmobile and 3G/LTE for AT&T? Is this correct?
(My wife has Tmobile and I have AT&T so I want to buy a phoen can works for both just in case )

[Q] HTC One compatibility

Apologies, but I have a noobie question for the experts.
Will a U.S. version of the HTC One work in South Korea?
If so, could you explain to me the details about this?

I'll refer you to the stickied thread explaining that this is a beginner's thread. Everyone is "allowed" to ask questions. Also, answering a question in a Q&A thread with condescension like that really isn't in keeping with the community here. If you don't like the question, you don't have to answer it.

Does the d4 use both 2100 and 900mhz 3g bands (europe) ?

Does the d4 use both 2100 and 900mhz 3g bands (europe) ?
I'm thinking of importing one or the samsung relay 4g, but do both smartphones work at 900mhz (much stronger signial here) ?

Not sure about that, but I can confirm you that 3G works perfectly in Spain with this mobile

Here are the bands supported.
2G Network CDMA 800 / 1900
GSM 850 / 900 / 1800 / 1900
3G Network CDMA2000 1xEV-DO
HSDPA 850 / 900 / 1900 / 2100
4G Network LTE 700 MHz Class 13

I have a Droid 4 in UK, and I can confirm HSDPA is working, but couldn't go higher than that, probably 4G is working only on 700 MHz, which no operator has in UK: hxxp://en.wikipedia.org/wiki/List_of_LTE_networks#Europe

Will N910G work with T-Mobile 4G?
