[Q] Bad ESN's and frequencies in Australia

Hi guys,
I've had a look around and can't really find much info on bad ESN's. Most of the questions are resolved with a -"find a carrier who will reflash your phone". The phone I'm looking at is from someone who didn't pay their phone bill. If I import this phone over to Australia - what will a bad ESN do? I'm planning to buy a pre paid SIM card over here, and I'd like to put a basic Gingerbread rom on it.
I can see that a bad ESN means you wouldn't be able to use the phone on the network it was sold on, but if you unlock the phone doesn't that mean you can put on whatever carrier you'd like?
Are there any issues with doing this?
The next part of my question is about the Vibrant. From the info I've found this...
Will My SGH-t959 (Vibrant) Phone Work In Other Countries And How Do I Unlock It?
The SGH-t959 is a quad band dual mode handset. It supports GSM frequencies of 850, 900, 1800, & 1900. It supports UMTS 1700, 1900, and 2100 frequencies. There is a possibility the phone may be used with a wireless operator outside the United States however this is not guranteed. The phone has been optimized to work on the intended carrier it was designed for.

From what wikipedia says on Vodafone (in Oz,)
The GSM mobile service on 900 MHz and 1800 MHz covers 94.52% of the country. The 3G 2100 MHz UMTS network is available in metro areas of major cities and some larger regional centres covering 80% of the population. Expansion of the 3G UMTS network using 900 MHz to equal or surpass the GSM coverage is due to be completed by 31 August 2009 [1] [2].

Will this work here? It's seems like it should? (I'm in Melbourne) I'd like the 3g to work for the internet etc.
Thanks guys.

Beumpp....

I can't guarantee it but technically according to the site below, it should work:
http://www.phonearena.com/phones/Samsung-Vibrant_id4747
UMTS[3G] frequencies: 1700/2100, 2100
Optus, vodafone and three use 2100 and 900

[Q] Enabling all of I9000 quad WCDMA bands

Hi fellas,
I was wondering if enabling all WCDMA bands 850, 900, 1900, and 2100 of our i9000 phones would produce any bad effects or would deteriorate our phones or its parts?
I tried to enabled them in *#2263# and they seem to be persistent so i believe they are active. It was initially set as 900/1900/2100.
Looking forward for replies

if you bought i9000T it's supposed to work with 850 what the others can't, that's from what I know..

I'm just not sure if it is really functioning or how to verify if the phone is really using the 850 or 900 wcdma band, or both (together with 2100 and 1900). AFAIK, wcdma's requirement is that at least 2100 is enabled, paired with another supporting band either 1900, 900, or 850. (tho just 2100 solo will also work but not as best if without another band to use)
I'm also wondering, if the original i9000 can support quad GSM and quad WCDMA, why is it that it is only set as tri-WCDMA only?
I guess my only concern is that if the phone's antenna system will be damaged if i enable quad band WCDMA (if it is really using it)

Folks,
If you have checked with the Service manual and Schematics, some variants of Samsung Galaxy S lack the required PAM for the UMTS Band VIII (900) operation physically, while some lack the required PAM for the UMTS Band V (850) operation. Sure, we can flash it with the corresponding modem.bin, toggle "WCDMA 900 (FDD VIII)" and/or "WCDMA 850 (FDD V)" with our targeted Galaxy S variants in the Band Selection menu but it does not mean they will actually work in the "Quad-band WCDMA" as we would like.
Try to hook one up with a set of signal isolation box, signal generator and analyzer (R&S, Agilent, etc.), then you will find out our Galaxy S is capable of "Quad-band WCDMA" or not for sure. DO NOT get confused with the "Quad-band GSM"... "If it can do quad-band in 2G, then why not in 3G?" BECAUSE the it is handled by another set of PAM and FEM.
Nevertheless, most of us are doing fine in the EURO/RoW regions where most 3G networks are deployed in the UMTS Band I (2100). Unless we are heading to the rural or specific areas where only has got the 3G service in the UMTS Band VIII (900) only (AND we apparently must use the 3G service at the same time).

thanks howipig, very nice answer

Project1.exe,
No problem but I wish someone out there can make our dream come true by adding the right PAM and SAW filters for the "extra" 3G band support

i'm thinking if it would be possible to extract files from, say, a Rogers (Canada) SGS for the 850, and combine them with euro for 900. I'm actually using XWJV1 (leaked gingerbread) and I got excited cause I see both options.

Project1.exe,
Like I have mentioned before, the software is just part of the puzzle. We can toggle all 3G bands showing in the Band Selection menu. In fact, I have played with a modified Galaxy Tab that even has UMTS Band IV (AWS) selected too! But in reality, it never works on the AWS band. The PHYSICAL hardware is the key. Without the right components, we are not going to make it happen.

[Q] 850 band on GT-I9000

hey,
i have a GT-I9000, and i'm trying to enable 850mhz band for 3g,
i flashed the jjjv5 modem which is 850enabled,
and selected the 850 band through *#2263#*, the second i select 850 i get no signal, does that mean my phone isn't 850mhz capable or does it mean there is no 850mhz reception in my area ?

galaxy s suports all bands
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 900 / 1900 / 2100
so you dont have 850 band in your area.

perhaps i was not clear - i'm trying to connect to 850mhz WCDMA band, not GPRS/GSM.

where do you live ? do you have the international i9000?

i live in israel, where we have a 850mhz/2100mhz 3g carrier (Pelephone)
the phone was purchased privately, not from the carrier.
i'm not quite sure about the phone version, the box states UMTS bands as 2100,1900,900.
the writing on the box and every document about the phone states GT-I9000.
does that mean that 850 3g band is not possible for me ?

i9000 doesnt support israel's 850 3g band, you can use 2100 instead which is suported by both ,phone and carrier

I'm also having a similar problem. im in Honduras with Tigo paid for 3g but only connecting to edge, i have the gingerbread xwjw5 build. I have a unlocked gt-i9000

only if you have the I9000T you can use the 850 band

Lost Reception+Data Connection on Rogers Network

Hey guys
I got XZ C6603 today from handtec. I activated brand new LTE simcard at rogers store and set up lte apn.
Soon as I did that data connection rapidly changing from h+ to 3g for a while then drop the data connection and phone reception as well.
Seems like lot of ppl here in Canada having trouble getting LTE connection but I am having hard time getting my phone reception and H+ connection.
I'm not sure either XZ is defect or this phone is simply wont work with Rogers.
Any solutions?? or should I just return the phone back to handtec?

LTE doesn't seem to work with the Z on Rogers.
Go into network settings and network mode and change it to only WCDMA(preferred)/GSM.
3G and HSPA+ work flawlessly so keep it on those instead.
Basically the phone keeps searching for an LTE network but can't connect so it'll keep switching between the network modes.
I'm hoping there's a solution to this soon, because the Z can actually find the Rogers LTE network but can't connect for some reason.
Probably a work around fix that can be done. :good:

Now I have solid reception + HSPA+ Thanks! :good:
Hope we can use LTE soon though

HSPA+ will probably be unpredictable on a regional basis - many North American carriers use UMTS1900 and the 6603 does not support that band for HSPA+ operation.
6603 will not operate on LTE in any band in North America I'm aware of.

You are wrong,
Rogers does support LTE 2600

I would not use a phone on Rogers that can't get 1900Mhz but ... You should be able to use 2600 LTE. Have you entered the LTE APN ?

HSPA+ works fine where I am on my 6603.
People have been able to get LTE on theirs as well, depending on the region.

My LTE worked for an hour the other. I've read the 2600 band is a higher speed band, but it has weaker penetration and more sensitive.
Im beginning to think that you need both 2100 and 2600 bands for LTE to properly work in Canada since Rogers have both deployed simultaneously. Maybe Rogers need to improve their 2600 deployement in order for the XZ to work.

You need band 4 and band 10. Each frequency is used for different reasons (upstream/downstream). Just having 2,600 Mhz won't do anything. It's already been confirmed by multiple users that LTE doesn't work in North America (AT&T, Rogers, etc.)
That's why the C6603 wasn't released in North America.
The leaked C6606 model should support it, as well as the ZL. (http://playstation.com/psm/certified.html)

Then how does the optimus g on rogers use lte 2600? The optimus g 2600 on rogers only have lte band 700/2600 according to rogers website. This is the first carrier phone to use the 2600 network I believe

Because it uses 2,600 Mhz (band 7) for the downlink and 1,700 Mhz (band 4) for the uplink (even though it doesn't list it in the specs).
(Going into the Service Menu on the Optimus G shows off its full band support.)
Without the appropriate uplink AND downlink support, LTE will not work.
Rogers has LTE deployed on bands 4, 7, and 10.
The C6603 supports bands 1, 3, 5, 7, 8, and 20.

lg g flex d858 in tmobile lte does not work

Hi,
I bought unlocked lg g flex d958 and now I'm using tmobile 4g network. The problem is my phone does not work with lte network. I only get EDGE. I live in Michigan, USA. I really appreciate is someone can help me. I've done a lot of research and readings about this.
First of all, some threads suggest to do the band selection. The code 5457#*958# does not work with this phone. The hidden menu code is 3845#*958# works with this phone. Unfortunately, when I try to select band selection, I can mark the band selection but there is now way to save it. I click "back" and return to band selection and it returns to normal.

Guy, did you buy the worse model to use with t-mobile
3G Frequency in T-Mobile 1900
HSDPA 900 / 2100 - D958
4G Frequency in T-Mobile 1700/2100
LTE 800 / 1800 / 2600 - D958
Then, to you, just 2G Edge conection
There is no solution, is a hardware restriction
