Two question about the ASUS P535 (phone module) - Upgrading, Modifying and Unlocking

I'm sure that this device is usable in europe (gsm 900/1800), owever can I use it in the USA ????
Second question...if I'm using the GPRS connection, at the same time, can i receive a call??
Tnks, to all!

since us is 900/1900 and eu is 900/1800
you can use it in us if you can find a place where they are running 900
and yes GPRS should not blok the phone from working as a phone

....tnks!!

US is 850/1900 (not 900). Most carrier support 1900 but you got extra coverage in area where only 850 is exist.

I use it (Taiwan version) in California. It works, but TomTom6 still not useable. I already order the US map, let's see what's going on.

Universal questions

Hi guys, i am getting a universal from the UK in about 2 weeks and i have some questions.
1. Is it unlockable yet?
2. Is bluetooth stable, not cutting off during calls and stuff?
3. Since it is WCDMA, does that mean i can use it with CDMA services here in the states like sprint and Verizon?
4. What is the best case for it
Thanks for reading my questions, you replies will be greatly appreciated.

Hi Obiesoft,
1. Not yet to my knowledge... Keep an eye on the 'universal' unlocker from this forum. An app that is updated over and over to add support for new phones.
2. Did not try yet, sorry, one of the other ones ?
3. Most likely not. UMTS here in Europe is on 2100 Mhz, as radio bands are of course regulated per country, you might want to see with your wireless provider if they a) use 'UMTS or WCDMA' as a standard, and b) if they also operate on the 2100 Mhz band. In the phone there is only one band available for UMTS connections.
GSM in general is provided in bigger cities in the states, you have to check which wireless provider has it in your area, some might even have the Qtek 9000 with an interesting price if you take one of their plans.
(T-Mobile) Be carefull nevertheless, the USA has GSM services on 1900 Mhz and on 850 Mhz, the Universal can do w/o a problem the 1900 Mhz band, but to my knowledge not the 850 Mhz band. You would be out of luck if your cellular provider only provides services on this band. Check also if you have to be a lot in rural areas, as far as I notices coverage there is way less on GSM systems.
4. I'm happy with the 'leatherishlike' one it comes with. Sleek, and it does protect it very well. Snug, just no belt-clip, that's all.
Hope you'll be having fun with your device ! (Well, all depends of course if you can get it either sim-unlocked or from one of your local providers...)
Willem
Thanks
Thanks for your reply
I hope there will be an unlocker soon, i have Tmobile here in Florida, i will call to find out of they use 1900 or 850Mhz. I will probably try asking Tmobile UK or something.
The reason for me asking if it will work with USA CDMA is that i also have an account with a CDMA provider so it would be cool if i could use two providers on one phone, probably switching between them.
I have a MDAIII with WM5 and the bluetooth does not work, keeps d/c so i hope this one stays on with the MDA PRO.

I know that T-Mobile Germany sells the device w/o SIMlock. Might be an option. The QTEK versions of the device come also w/o SIMlock. I don't know if T-Mobile Germany ships the device outside europe, you might want to have a look at http://www.expansys-usa.com, they have a Spanish version of the QTEK you can easily reflash to the WWE version, new and not locked for a whopping 1045 USD.
P.S. I have no commercial relation to either T-Mobile or Expansys and both links are provided only for informational purposes.
Obiesoft, I have PM'd you.
simlock
t-mobile.germany has no SimLock - that's right!
but they did a NETLock!! - you#ve got to pay 100-300 € to get it unlocked for other networks. If You know where to find Band-Information i can tell you if it supports yours.
Universal is not working on CDMA One/CDMA 2000/EVDO networks.
In US, it will work for voice calls and GPRS on the 1900 networks like T-Mobile US. You will have to wait for T-Mobile US to launch UMTS (WCDMA) as it is planned, but I'm not sure they will use the same bands as in Europe.
MDA PRO
I did not check here sooner, my girlfriend is in london and she got the MDA PRO since she just renewed her contract. I am guessing it will be locked cause she is just shipping it and i will get it next week. Tmobile UK said they can unlock it for 15 pounds and it will take 28 days, so in the mean time i am hoping there is another way for me to unlock it.

MDA PRO TMOBILE USA SETTINGS

HI all, thanks here for all your help. I finnaly have my unlock code from T-mobile UK, for 30 pounds, but i think it is workth it.
Now using the PRO as a phone, it is kinds weird to get used to. I live inthe US and i put my T-MOble US sim card in, when i check the settings, i found out for some strange reason that the GSM band it was using was EGSM+DCS1800, i don't know what this band is, but i noticed that i don;t get enought bars, always loosing signal, and i have put the new 1.08 radio rom on it. My SK65 gets better signal.
The only other option i see there for GSM band is PCS1900, so i have manually set it to this. My question is, which band should i be using? whats the diffrence? and when setting up WAP for MMS, do i use WAP1.2 or WAP2.0.
Also does the UTMS2100 mean it will work on Sprints 2100 network?
Thanks.
Search is your friend
All of the Universal forums are full of information about why the MDA Pro is not as useful in the US because it is just Tri-Band. T-Mo USA uses GSM/GPRS 1900 for voice and data. You need to stick to this band alone. Try using WAP 1.2 for WAP. There's no EDGE available on the Uni.
No, Sprint won't work It's different technology using a different standard. You can only use UMTS in Europe, the Middle and Far East. That's why this device is targeted for these markets and was never brought to North America. And it never will be.
Let's hope the successor to the Universal can do it by incorporating the latest technologies prevalent in North America.

Let me get this straight - So TP2 is not a true "world phone"?

I'm a little green when it comes to 3G stuff, but please correct me if I am wrong...
Yes, you can put foreign SIM cards in US TP2's but not get 3G coverage in Europe. On the other hand from what I have read, European TP2's (even the unbranded ones) will not work with 3G is the US.
And if I am wrong... can someone please point me to a TP2 that will work on 3G networks in most of the world?
Or does one have to have two TP2's to enjoy 3G.. one for the US, and one for Europe, etc.?

Where have you heard that a NA TP2 won't work with 3G in EU?
The only limitation I'm aware of is a NA TP2 won't work w/ NA GSM 3G.

Until someone hacks it
I can't remember where I read it. But someone said if you wanted 3G in Europe, better to get a Euro unbranded model.
So perhaps this is under the assumption that it isn't hacked... not sure.
Slightly, off-topic Q but rather than start a new thread.... once a HardSPL is out for both the CDMA and GSM TP2's... will they effectively be "equal" devoces?
I really would like to pick-up a TP2 in the next few days... I like the VZ unit, but it's CDMA and since I travel quite a bit, really prefer and need more of a GSM phone, but don't like the TMO as no 3.5mm jack.

The Verizon unit already has international GSM bands unlocked, AND international (2100MHz 3G). If you've been a Verizon customer for 60 days or more you can call them up and get an unlock code for free and use any SIM card in your phone so you can get a cheap prepaid SIM and not pay the high Verizon roaming costs. There's also a small (I'd say around 25%) chance that the NA 3G bands will be found/unlocked, but at this point who really knows if they are there or not.
Actually the Telus CDMA TP2 supports the European 3G bands but not the American ones becuase technically you will be using it in North America on CDMA and outside America on GSM. So its the other way around
It seems that if you have the Sprint TP2 that it won't register at all on US GSM networks, but comes unlocked by default.
On Verizon (which I have) a simple phone call to support they'll give you the unlock code and you're good to go. I use an Orange (UK) Sim in mine just fine in the US and others in other forums have reported that using US SIM's from TMobile/AT&T work fine also in the US.

I have an unbranded HTC factory TP2, and it works in 3G mode anywhere I take it that has the 3G network... and I travel all over the US/Caribbean and back to EU/UK. Have not found one spot it hasn't worked (inlcduing some of the very obscure Carib countries), and I like the fact that it automatically picks up HS when within range without having to change any settings.
Just have to make sure that your provider gives you a 3G SIM (most of them are these days) and that you have the 3G service enabled on your account in the respective country.
Many people say they can't pick it up yet don't have it on their account, or think that their EU provider will automatically provide it as part of the roaming service... which is not a good assumption to make.

3G in North America? I doubt that. The phone does not support North American 3G bands. Are you sure it was 3G in North America??
Man, this is all confusing... I swear somebody has to come up with an HTML table of what phones work with what and where and stickify it.
Can people just put this to bed already!!!
The Sprint (North America) TP2 is suppossed to be used on CDMA in the US and GSM worldwide, hence the GSM radio is unlocked for outside America GSM use. This is how it comes default. If that is so hard to grasp, then there is no hope for some, sadly.
As for the title, the TP2 is a world phone, it works in the US (and North Ameria) on CDMA and elsewhere unlocked on GSM. That to me is the true definition of a World phone from a U.S CDMA perspective (and especially moreso as this is the CDMA version).
To put it in perspective, a Sprint customer (in this case, moi) gets the best of CDMA in the U.S and when traveling to visit his sister in High Wycombe in the U.K (like i'll be doing this Autumm) gets to pop in a PAYG U.K sim in the same phone and use it while over there. This phone doesn't get any "worldlier" to me than this scenario!!
Is the O.P attempting to specifically define a dual mode CDMA/GSM-unlocked World phone as not world phone because it's locked by default from doing GSM in it's primary market which happens to be CDMA (and in this case Sprint)?
This is not rocket science folks, it really isn't.

Point taken. It's just that with that same Sprint phone (correct me if I am wrong), you can't travel to Canada pop in a Rogers SIM card and get Rogers 3G.
Wouldn't the phone want to swing towards it's CDMA cousin, Telus or Bell?

AT&T 3G runs on 850/1900 GSM, the TP2 supports both of those bands, how would it not work with 3G on AT&T in the US?
T-Mobile runs 3G on 1700/2100 GSM bands, both of which aren't included on the TP2, as far as my research has lead me to believe.
Basically while it may be a quad band GSM phone, it is only a dual band 3G device. It comes in two flavours - UMTS 900+2100 or UMTS 1900+850
The 900/2100 version is far more common than 850/1900

"it Depends"
The US CDMA phone operates in 3 modes.
1 CDMA Only
2 GSM Only
3 'Global' (whatever it can find).
If you have it in Global it will generally take the CDMA local carrier over anything else. However, not always. I've had mine switch to GSM for a bit then go back to CDMA. But mine is Verizon and unlocked so it works everywhere in the US and I also have a UK sim card in it. So I'm a little 'different'.
But, in any case, you can tell the phone which mode to use if you want. All upto you.

(verizon TP2)
here we go again... (tp2 3g na)
"I have an unbranded HTC factory TP2, and it works in 3G mode anywhere I take it that has the 3G network... and I travel all over the US/Caribbean and back to EU/UK. Have not found one spot it hasn't worked (inlcduing some of the very obscure Carib countries), and I like the fact that it automatically picks up HS when within range without having to change any settings."
So, maybe he's wrong. But either way...
You wanna know why this keeps coming up again and again?
(not because we're all dumb and thick headed, which we may very well be)
But,
Because we just have trouble imagining them hardware "band amplifier" hobbling the hardware when it's so much easier to do it somewhere in firmware.
We all know that the less you fiddle with the hardware for multi-region functionality the less you have to fiddle with the production line and fiddling with the production line is the Last Thing a manufacturer wants to do.
Someone even once said that there wasn't room in the Rhodium platform for quad band data support. But now we're expecting the tilt 2 to do just that.
So, all protestations aside, those of us who paid ~700 us clams for this beauty, and who like the kbd layout.
And who have like me (as quite the Early Adopter), forked out for an sx56, sx66, 8135, x7510((quad band data)
Just feel a leetle wee bit of a sense, dare I say it, of Entitlement for the TP2 to be enabled into a fully world wide phone.
So we keep hunting, and digging, and dreaming, and .... posting.....
well here is my two cents i have the original unlocked euro version of the tp2 and all i get in the us it edge. it is really impossible to get 3g in the US (2100) because this version of the phone literally does not have the attena for it. and so that you can see all the different types of tp2s and the technical and physical differences between them here is a link: http://pdadb.net/index.php?m=pdacom...&id3=1792&id4=1829&id5=1766&id6=1989&id7=1751

3g in the USA must be on the 1700 band then, as thats the only gsm band that the euro version doesn't support.
Euro version
GSM850, GSM900, GSM1800, GSM1900, UMTS900, UMTS2100
TMOUS version
GSM850, GSM900, GSM1800, GSM1900, UMTS1700, UMTS2100
Anyone know of a good site to order a prepaid SIM card? I plan on using my VZW TP2 in Spain and France. I was also wondering if I should or could disable data and use my TP2 with Garmin XT so I don't get nailed for data usage. Your thoughts would be appreciated...

T-Mobile Tocuh Pro 2

Anyone knows is this phone (USA T-Mobile) works in Europe??
It 100% works on GSM and EDGE (2G and 2.5G)
As for 3G, I assume it may work on the 2100 band in Europe (does anyone know enough to clarify on that). However your operator in Europe may work on another band than 2100, since there are two 3G bans in Europe. Generally operators used 2100 first and then subsequent licenses were other bands. So in Norway, I know both 3G carriers use 2100 exclusively, but you should check with your carrier and clarify that T-Mobile USA supports the EU 2100 band and not just AWS (which is a mix of 1700 and 2100).
Thanks for quick reply. 3G works on WCDMA standard? If it is so, my operator use 2100 mhz so maybe it will be working, it will be my first 3G phone so I'm not sure what I suppose to check.
I found this:
http://forums.t-mobile.com/t5/T-Mob...1;jsessionid=2085F63B05DB5B6FFA511D3C33A9EE69
According to this site TMobile touch pro 2 phone use Bands: 1 (2100) & 4 (AWS 1700/2100).
Band 1 is Europe standars so I hope it will be wroking.
I let you know when I get the phone.
Any particular reason you are getting the USA T-Mobile version and not the EU version or one from a local carrier?
Also the T-Mobile version is locked, so you will need to unlock it using the tools on this site.
If you get 3G or not should be pretty obvious. If an H or 3G icon appears, you have 3G. Otherwise if the data icon shows E or G then its only getting 2G.
the main reason is the price
tmo $450 vs eu $650
Yes main reason is the price. I get this phone for 270$ in my country it coasts about 550$. I know I must unlock it but first I must get it to my hand.

UMI X2 and T-Mobile 3G

Voice and data quality are very bad, almost the phone is unusable. I spoke with T-Mobile and was informed that my modem does not support 1700 MHz and there are effort to re-farm TMobile network to support 3G on 1900Mhz but not set date yet. When I scan for available network I get three networks were available

Did you make any progress with this? I recently purchased UMI X2, for use with T-Mobile UK. But have the same problem of not being able to connect to 3G networks - it works okay on 2G/EDGE.
I know the phone supports 3G on 2100MHz, and there's been some debate whether it supports 850/900MHz as well, but I've not found a definitive answer to that.
There's an operator in the UK (Hutchinson 3G UK Ltd) that only have a license for 2100MHz. So I was expecting the phone to work fine on their network- but no go... phone won't register on network at all - even though it shows in the available networks list.
I'm now searching to see if anyone else has been having problems - as it's beginning to look like faulty phone hardware - rather than trying to use unsupported frequencies...
acid meaand
I am still in the same situation, I am unable to use the 3G network for T-Mobile.
I am looking into getting 4G Wireless Hotspot modem $50 from the same carrier, use my SIM card on the modem, and use my UMI X2 as pure IP phone. There are many issues, but it looks promising.
Please keep me updated with any progress you make.
Regards;
I have the same problem...
I have this same problem with a operator here in Brazil. Every 3G operator in Brazil, using 2.1GHz band, works fine except one: VIVO.
I can see the network when I click on "manual search", but the phone can't connect. My baseband is:
moly.wr8.w1248.md.wg.mp.v7.p1 2013/04/10 00:39
How can change this baseband to another? I tried to update firmware but unfortunately the newest firmware has the same baseband version.
firmware update will not solve the problem
Firmware update will not solve the problem. Until the manufacture identifies the problem and provides a solution, the problem is outstanding.
Beside the hardware has to be compatible and can support more frequencies which no one can confirm for the UMI or any other chines unlocked phones.
But, this is just my humble opinion.
I Found a solution (at least for me)
I think I found a solution for my problem. I flashed this very new (2013/07/17) rom, with a new baseband MOLY.WR8.W1248.MD.WG.MP.V7.F2.P1, 2013/07/10 23:14 that corrects 3G dropouts and disconnects. Now my 3g works find, with H and sometimes H+. Fast and reliable like it should be. The link for this new ROM is:

Thanks for the update.
I have two questions.
1- There are two files in the link you provided UMI-X2-basedon_Official_250613.zip and UPDATE_UMI-X2-THB-ROM-based_on_Official_170713.zip. Which do use?
2- You mentioned the updated corrected 3G dropouts and disconnects, but do you know if the update have these frequencies to get 3G?
3G (850, 900, 1700, 1900, 2100 MHz)
HSPA+ 42
P.S

I used the file UPDATE_UMI-X2-THB-ROM-based_on_Official_170713.zip. It was based on the Official ROM from 07/17/2013, but I was unable to find the official stock version. This version has a very new bandbase that, supposedly, fixed the problem with 3G on some operators.
3G on Brazil is on 2100 MHz, sometimes on 850MHz but in my case the problem was on 2.1GHz band. Three WCDMA operators in Brazil, all in the same 2.1GHz frequency, work fine, but VIVO doesn't. Now, with the new rom, it works with no drop outs for over a day now.
no changes or additional frequencies
I successfully applied the update but no changes or additional frequencies
I have serious issues with HSDPA, t-mobile uk works but only on GPRS and it keeps dropping out. GiffGaff seems to work without dropping out. It has worked for a minute on HSDPA today but only once. Other than that t-mobile has been dropping out badly. GPRS works for a bit then it drops out. I have took an MTK modem log with MobileUncle Tools to see what it says but haven't looked at it yet. Trying to work out if it is a hardware issue or Baseband.

Hi,
do you have a description and a photo of how you did it?
How long the Cu wire has to be? And where to connect it?
Many thanks in advance.
