Would it be a big deal to make the XDA tri-band GSM ? That's
what I would really like in the XDA.
thanks.

The GSM part in the phone is said to be dual-band 900-1800 or
900-1900 only. So depending on what market you buy in, you get
one or the other. (model PW10=900/1800, PW20=900/1900 ?)
If you're in Europe, you could get a 900 subscription on an
unlocked U.S. phone, which would then also work in the U.S.
(But with roaming rates the way they are, you're better off
getting a pre-paid SIM when you're there.)

O2 xda tri-band phone

Hi there!
I live in France and I go often to California. I always had a spare GSM phone tri-band for the US and Canada.
Last March, I bought an O2 xda in Australia, in a Telstra shop, thinking it was a bi-band phone. Back in Paris, I found this site and learned how to access tho the GSM menu (I had found myself how to access to the Wallaby bootloader 5.17, but I didn't press any other key after the message "GSM OK").
I've just come back from San Diego and while I was there I changed the band to "1900"... and the xda worked perfect!!! Back in Paris, I've switched back to 900/1800 and I'm using again the European networks
Thank you!
What?
We've always believed the phone had physically different hardware for 900/1800 and 900/1900 operation, and I seem to remember seeing negative test results.
The O2 XDA you bought for sure is 900/1800 and not 900/1900 ? (remember: it would work in Paris if your provider is on 900).
Let's all follow up on this one carefully. For now, let us not imediately assume the units are tri-band.
I have heard that O2 are likely to release a tri-band version with 64Mb internal RAM.
This will be called the XDA 64i and is likely to sport Bluetooth also.
Any further news on this appreciated.
Hey ArtZ
Let us know if your carrier is a 1800 Mhz Carrier.
If the XDA is triband that would be absolutly awesome.
:lol:
Hey guys
Now this is VERY IMPORTANT NEWS
Can we have more info and more confirmation (more experience in this ?)
My carrier, SFR is a 900Mhz carrier. In fact SFR (Vodafone) and Orange (France Telecom) use the 900 Mhz but in some places to avoid network congestion they use also 1800 Mhz band. BOUYGTEL (Bouygues Telecom) uses only the 1800 Mhz band.
I've just made a test. I have configured the phone as 1800 Mhz only. I couldn't find my carrier SFR. Then I tried to select manually the network and I only could see BOUYGTEL (1800 Mhz). I have tried in the past my XDA with a BOUYGTEL car also and it works fine. So my phone is configured for 900/1800 carriers.
After this, I changed network again (1900 Mhz) in Wallaby bootloader. Then I cannot see any carrier. In California I was connected to Pacific Bell using the 1900 setting.
As I told you before, I bought my xda in Australia last March with the latest firmware. It's a 64 Mb internal RAM
I'll be back in California (on vacation) on June 30th for 10 days. If you wanna make tests...
Hi ArtZ
This sounds great.
Sorry to bother you, but can you tell us please which firmware U are using for the PDA and for the phone?
Thanx! :idea:
PS: for me it will be end of the year, so this is a long time...
I forgot to tell you the versions installed (I haven't updated them yet) are:
RUU 3.14.17
RSU 4.17
I don't think my xda is the XDA 64i. It has no Bluetooth. I think the 64Mb version just came out in Australia when I was there in March. There're are maybe harware changes with the 32Mb version and the 64Mb is a tri-band.
Hope that helps.
It's me again, sorry to bother you.
I run all the tests from the Wallaby bootloader. The version I have is GPRS 4
It will be interesting to check if you have new versions over there.
I found out that the xda has just arrived in France by Bouygues. I will try to get more information about it but I think it's the same model I have. Bouygues doesn't say if the HTC iPDA is a bi-band or a tri-band telephone

Hi,
My version is GPRS 4.1332s54 What ever this means? :shock:
how to change the frequency?
HI Artz,
Great news you have given. Can you please clarify step by step how you changed the network frequency of the phone?
Thanks

Look on the back of the device, the part number will tell you if it is a 1900 unit or not.
PW10A1 is the 900/1800
PW10B1 is the 900/1900
The Bootloader is identical. CE is different as the option to chose the 1900 band (which you have to do manually) is only in 1900 CE versions.
The hardware is different between the two versions. The radio circuits and filters are different. You "could" switch the radio of a 1800 unit to try and do 1900, but your coverage would be extreemly poor as the 1800 filter is actually filtering out half of the 1900 band.
Your 1900 operator will NOT like you.
superblurr, lazy boy! :roll:
All information is here, in xda-developers.com. Just take a look at this page
http://www.xda-developers.com/bootloader/
It will be nice if someone from the States comes to Europe and try his xda here. And if you go to the States (or Canada) take your xda with you. It's the only way to find out if there're different models
My version is:
GPRS 4.1332s54 (as silversurfer)
RUU: 3.14.17
RSU: 4.17
Model: PW10A1
Anybody got a spare XDA they want to send to the US for testing for a few days? It usually only costs me about $12 to ship something that size to Europe, and takes about 5 days. I would imagine it to be similar the other way.
this sounds great! i own a 900/1900 from t-mobile. is it then possible to change my 1900 into a 1800 mhz? because i get sometimes no network signal. i live in europe, and need the 900/1800...
Can anyone explain please?
I bought a US T-Mobile (PW10B1) and did a SER1.2 flash, it went flawless....Thanks to the xda-developer team and Jef, you guys are the best!! The only bug I notice so far is Phonext which is not working at all. I am using the phone in Singapore using the 900/1800 band and it works perfectly. I've been reading about TMO2003 in this forum, my question is does this upgrade come with bandswitch.exe, this feature is very essential to me as I travel very extensively btw Asia, Europe and the US. By the way does anybody know what is a .rar and .nbf file? :?:
.rar files are compressed files like zip.
download a freeware prog called winrar and you'll be all set.
The UK will see the new XDA from O2 by the end of this year.
It's now known as the XDA II
it will be 64Mb, tri-band and bluetooth plus a built in camera and enhancements to the wi-fi link etc.
Thanks Rustek. How about .nbf flies? Is TMO2003 for PPC2003 only? what's the diff. compared to SER1.2?

WHERE CAN I GET XDA IIi?????

It would seem to me that the XDA IIi * is all that I need. But I don't know who is planning to release the Blue Angel with the 1.3Mpx camera. Does anyone know the approximate price in whichever currency? Anyone know anything more?
*I don't care how it's branded, I just want the faster cpu and bigger cam of the IIi.
xda iis
try this:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=64355&item=5720213253&rd=1&ssPageName=WDVW
but i would rather wait for the real xda3.
Can you confirm the specs of the MDA III?
a) Is it Windows Pocket PC Second Edition (with the screen rotation)?
b) Camera resolution?
the one being sold at ebay is actually (i think) an xda iis or 2i. It has the new form factor (w/ slide out qwerty keyboard), comes with wm2003 2nd ed with landscape mode and built in wifi.
However, its screen resolution and camera and all other features are the same as xda2.
The xda 3 however, which will come out about the Q2 or Q3 of 2005, will have a faster processor (650 mhz), MP camera, better screen resolution, etc.

T-Mobile in the US says they don't plan to carry it. Verizon says they expect it by early next month. I'm 99% sure I'm going to switch carriers, since Verizon also now has their high-speed EV-DO network running, and I'm tired of 40k GPRS. Plus I'd find coverage in rural areas useful.
Verizon XDA IIi
Hi Carlos
Is the Verizon version also a GSM phone, or is it a TDMA device? I have lost track of what technology Verizon is using these days.
Verizon is CDMA. So you lose things like the SIM, which I do find valuable to swap into another phone. But I don't see T-Mobile doing anything to improve data, while I watched a Verizon EV-DO user pull down 627k/second the other day. :shock:
Thanks Carlos. Yes, the data rate sounds impressive! Any idea how I would get on if I travelled to Europe? What happens with Verizon over there wit out GSM?
Your GSM roaming abilities would be zero with this device. North American only (US/Canada/Mexico). Verizon does have some roaming agreements, but you'd need a GSM phone and you'd have to set it up with Verizon in advance. Really though, it's far cheaper to buy a pay-as-you-go to use in Europe, as all the US carriers charge $1-$2 per minute for international roaming.
Thanks Carlos. Yes, I use an O2 pay and go SIM now while in UK, having found out the hrad way about T-mobile international roaming....! Guess if I switched, I would just keep some kind of GSM device for use in UK

[Q] Lumia 920 from BUILD 2012

Hi,
Got a Lumia 920 from Nokia at BUILD 2012, and it has been working perfectly here in Norway, but I am unable to do any testing of LTE. The provider, Telenor, has coverage where I want to test, but I can't seem to get a LTE connected properly, and Telenor only suggests getting support from Nokia directly or trying to get a firmware update as there are no wrong settings or restrictions in my subscription. The "extras+info" list the phone model as "RM-820_nam_canada_246".
Questions:
Is it possible to flash this dev model with the Telenor software/firmware or will that brick it?
Are there known LTE differences between this US/Canada model and the ones sold in Europe?
Will the Nokia Legal Action Force break down my doors for this?
Thanks!
The version we got at BUILD 2012 is a Canadian version L920. The frequency it supports is printed on the box. For LTE, it supports 700/850/1900/1700_2100 MHz which are primarily North American frequencies. Europeans use different frequency bands. You need to check with your carrier to see which frequency band its LTE service uses. There are more than two dozen different LTE frequency bands used through out the world. Hence there is no such thing as world LTE phones yet.
I wish I had one of those Build Nokia 920's. Single most wanted item in my list.

It is not dev unlocked and so far received zero update from Nokia. Simply overrated.

Compatible US carriers?

Is there any available information on the US carriers that use this phone? I am unfortunately on sprint so I know that the chances are non-existent but I'm still curious on who will get this. In my short google searches, I see Verizon pop up quite a bit.
Will probably be a GSM only phone, too early to say though. If T-Mobile and Sprint merge your concern will no longer be necessary, but it's not clear whether that deal will go through soon.

Ouch. No B66 nor B71 for T-Mobile. I think LTE-U is missing as there's no mention of 46/252/255.
FDD-LTE (Bands 1, 2, 3, 4, 5, 7, 8, 12, 13, 17, 18, 19, 20, 28, 29, 32)
I would gladly give you a kidney tomorrow for an Asus ROG Phone today.
Any further info heard on a North American release? Been all silent from what I can tell.

What does the U indicate in LTE-U? And, what type of channels have a B attached to them? According to T Mo, and ASUS channel listings there are channels 2, 4, 5 available. I ask because I am also a T mo customer, and I want to buy this phone very much...

They are referring to Band 66 and Band 71. Band 66 is a combined band of two of TMobile's bands. I think 2 and 4, to increase throughput. Band 71 is the new 600Mhz band that is being rolled out. This low frequency band will greatly increase building penetration and cover greater distances. Band 71 roll out is scheduled to be mostly completed within the next 2 years. So for those who keep their phones for more than one year, or who live in an area where it has already been rolled out, they will see no benefit from the expanded coverage. The phone does support 2, 4 and 12 which are the minimums for a TMobile customer.
Edit: I was wrong on band 66. It's an extension of band 4 used to increase download speeds only. You can see more about it here https://www.phonescoop.com/glossary/term.php?gid=570
Sorry for not understanding all the band talk, will it be available for Verizon? Also, anyone think it'll be available through Verizon?

Big Red needs B2, B4, B13, BC0 and BC1 (CDMA).
The first 4 *are* present in the ROG. But, I'm not sure if VZ allows non-VZ phones to be used, or if the IMEI has to be whitelisted for their network.
Taiwan version works on AT&T network.

As long as you already have an active Verizon sim you should just pop it in and it will work. I have done this with non Verizon unlocked phones while having phones repaired.
You may have issues if were to go into store and try and set up a new account using it. This may depend on your store you go into as well. I have heard of some stores doing it with no problem, while others wont do it or have issues.
So I have Verizon sim. Data is working no problem but it won't make any calls. Says mobile network unavailable.

This could be caused by multiple different things.
1. It could be caused by an app that supports calling (ex. skype, tango or similar) being set as the default calling program.
2. Needing to switch network type in network setting to force it to acquire the needed network info.
3.The phones APN might need changed.
4. If the phone is dual sim try the other slot.
@Mdaly001 Which model do you have? Which region did it come from?
It's the international model. Shipped from Taiwan. From what I can tell there is no difference from international and usa model.
So in apn settings but won't let me edit existing nor add a new one. The only thing I can change is the apn name. Can't change mmsc settings or anything else. This super frustrating

From Tech spec page on Asus website, the phone has 2 versions (A and B). Only version B has CDMA (Band BC0). Asus US store listing doesn't spell out which version is sold in US. But it listed CDMA 2000 (only exists in version B). However, it also states "This device is not compatible with CDMA Networks such as: Verizon, Sprint, and US Cellular." So I still don't know if the US version will "work" on Verizon. It's certainly not certified for Verizon.
For Taiwan version of the phone, can you enable VoLTE on your Verizon account and phone?

Sonim XP8 On Verizon

Okay, guys, I feel like I am getting jerked around by Sonim on this one. I want a rugged cell phone. Yes, I know that I can get many different phones and put them in an Otterbox. However, with FirstNet coming, I would love to get the Sonim XP8, unlock it from its AT&T bondage, and use it on Verizon until the A Fee & Fee network is robust enough in rural areas for me to switch.
Would a Sonim XP8 work on Verizon Wireless?
https://sonimtech.com/xp8/
https://www.droid-life.com/2015/02/...sm-cdma-wcdma-lte-verizon-att-sprint-tmobile/
VERIZON CDMA 0, 1 850, 1900 2, 4, 5, 13 1900, 1700/2100, 850, 700

VERIZON CDMA 0, 1 850, 1900 2, 4, 5, 13 1900, 1700/2100, 850, 700
The above makes it look like it would, but I just want to make sure.
Also, I did contact Sonim direct and received this response from them:
"Dear Jxx,
Thank you for contacting Sonim, the XP8 if unlocked will not work on Verizons network, The software is at the base installed locked with ATT software, if you tried uploading Verizons on the device it can brick the phone.
Thanks and Regards,
Axxxxx

While I suppose it is certainly possible that some software can brick a phone, all I would do is insert a Verizon SIM card. Now maybe Sonim is giving their CSRs that script, but it sounds like bull to me.
What do you guys think? Considering that this appears to have the appropriate bands/frequencies for Verizon, I suppose they don't want customers using it on Verizon until they have some sort of agreement in place with Verizon.
Someone with an unlocked Sonim XP8 tried an activate Verizon SIM card in it. It worked for data, but not voice. Then, when he disabled data, it made voice calls just fine. Can anybody offer any help on how to make it work with voice while LTE in enabled?
Sonim now sells the unlocked XP8 directly from their webpage. Expensive as hell though. Factory unlocked is nice, although rooting the damned thing is eluding me.
You can try here.

I know that is what they said. Supposedly this phone supports a good suite of frequencies. They may have them disabled, or the hardware may be different, of that I have no answer. I purchased one and immediately put a glass screen protector on it. It feels like you are holding a brick. For my mitts, it is very comfortable. Since it is listed as an enterprise phone, support for it should go 5 years. I will be glad when someone comes out with a process for rooting it. Factory Unlock and the 3 year comprehensive warranty is awesome. Good luck with verizon.
