Asus P525 GPRS problem - Upgrading, Modifying and Unlocking

Hello,
I have a P525 but use it on the TMobile US network. The phone works perfectly but for the life of me I can't get the phone to see the GPRS network. It's not the GPRS settings, it's that the phone doesn't even recognize that GPRS is available. No 'G' shows up in the top task bar.
I got my unit from Australia if that makes any difference which I don't think it should. TMobile Customer Care has no clue why I'm having the problem I'm having and ASUS Australia support couldn't help either as they don't know the TMobile network and ASUS USA support wouldn't give me the time of day since that phone isn't sold in the US. Been racking my brain trying to find an answer. Any idea in solving this problem would be appreciated. It's as if the GPRS modem/radio isn't on or something.
Thanks,
Ho'okani

3G USIM in 2.5G pda

I am tempted to go for the orange spv m2000 -although it costs more than the MDAIII- if I can use it with my orange 3G usim where I've got lots of free data allowance. Alternatively, I would go for TMobile but I would have to take one of these expensive data bundles.
Has anyone tried to use the SPV M2000, or the xda2s or the MDA III with a 3G SIM card from the same operator? Does it work?
I've read 2.5G phones would not accept 3G usim cards, but I spent the past couple of weeks in Canada where I used my Orange 3G USIM card in an unlocked Vodafone-branded Nokia 6600... and it worked great!
Any help would be much appreciated.
There is no reason why a 3G sim can't work in any 2G phone. Of course you will only get GSM/GPRS and not 3G services. I've used one in various xda's and no problems at all.
Having said that I have heard reports that sims from the '3' network don't work in xda's. Dont know if thats true.
Great
That's great, many thanks.
Are you happy with your xda? Is that the O2 one? Are you allowed to browse outside O2 active? and how much are you charged for gprs browsing?
cheers

ok i have been using 3G sim for few months. it able to send and receive MMS from my Motorola A780 and Sony Ericsson w800i if i edit the MMS setting. However, it does not work for XDA mini and XDAIIs. Normal phone call in and out and GPRS browsing is fine. But MMS cannot send and receive ..... anyone can ?
hi, guys! i've same reason that I'd like my BA workable with USIM but don't know what to do then. any help would be appreciated. thanx

Best Radio ROM for roaming?

My question is, when you are overseas using your local providers roaming options to still use your phone, should you use a radio that works best on the network in the country you are visiting or that works best on your home network?
I have tried 1.46.00.11 and 1.50.08.11 on my New Zealand Vodafone network and neither support incoming calls but other radio functionality works fine (also noted here). So I stick with good old trusty 1.38.00.11.
When I go to Japan next week I want this still to work so I am hesitant to put the "leading" radio in the poll on as I may not be able to receive calls.
I will be using SoftBank in Japan, but I will be receiving calls redirected from Vodafone. I'll take a couple of radio ROMS on my card to flash if need be while I'm over there, but I was curious if anyone knew exactly what the biggest influence is, your location and network, or the calling users location and network?
Hey Julz, off to Japan huh? Fascinating place, make sure you check out Akihabara if you are in Tokyo...
I was in Korea a month or so ago and could get my P3600 to connect to their 3G network (using the 1.38 radio), couldn't make any calls but that turned out to be a Vodafone problem. Seems that VFNZ don't have a roaming agreement for their 3G network...
So I'm guessing you should be ok with the 1.38 radio.
Only other place I've roamed with the P3600 so far has been Fiji, worked perfectly there with the 1.38 radio.
Thanks Ant
Yes, this will be visit number 4 and yes I love Akihabara!! Will see if I can pick up a dirt cheap 8GB MicroSDHC down the alleyways.
NZVF confirms their 3G agreements with a couple of Japanese carriers, so it sounds like I should be ok.
Just thought it was an interesting question to chuck into the mix regarding favourite Radio ROM's to see if people change their radio when travelling

no hsdpa/3g

this is a problem ive been trying to resolve with tmobile, to no avail.
basically the data network only seems to use gprs and not 3g or hsdpa, despite me being in an hsdpa area. my kaiser with another tmobile contract sim gets hsdpa speeds fine, as does the tp2 when its got the old sim in, but this new sim doesnt seem to allow it. it wont be a handset problem and its not a coverage problem, its as if its been disabled by tmobile. for the record both the contracts are identical. (the kaiser one has a few days left in it)
ive called and emailed tmobile frequently over the last week, but they dont seem to understand the problem and cant help. noone seems to have heard of hsdpa and the last phone call lasted over an hour, with the ending result being 'we dont know'
im aware that they might have to 'flick a switch' to enable it on my data plan, but cant quite communicate with them this.
anyone got any tips? could their be a particular number/email address i could use?
They probably indeed have to flick a switch. If all else fails, just request a new SIM from them saying this one broke or something.

I have the same problem but on Orange Romania. The THC is unlocked and on the TytnII the SIM has worked perfectly but in the new TP2 no HSDPA. With another SIM from Vodafone the HSDPA is working.

You're not the only one facing this issue i see! I have had a Tmobile contract for years on the TytnII and ALWAYS had the HSDPA working fine. I got the Vodafone touch pro 2 and now the best i get is GPRS or 3G. trying the settings>all setting> advanced tab> did not help either. I guess T-mobile can enable or disable this at will especially if they can detect the device type is not a Tmobile one...
Sorry for the lame question but how do I know what my connection is? My icon with the bars changes to "3G" when I use data but I noticed a friend's phone shows "H" instead. I already have enabled HSDPA in the connection settings but still get 3G everywhere and never seen H on my phone so far.

The problems I (and others) have with the damn Omnia 7

Been having problems with my Omnia7 since beginning of the year and was hoping Mango with firmware would fix these issues.
This is how it turned out after update...
I can't upload anything to SkyDrive on 3G (I get "The Windows Live ID Service is unavailable at the moment"), if I turn on WiFi it works instantly so there is nothing wrong with my account.
I usually can't download apps from marketplace on 3G, i get "The Windows Live ID Service is unavailable at the moment", if I turn on WiFi it works instantly.
I usually can't post twitts to twitter, I get some connection error. Not sure if that works over WiFi.
I usually cant do statusupdates to the Windows Live feed, I get some connection error. Not sure if that works over WiFi.
Bing search usually doesnt work on 3G. "We cant connect to search at the moment" if I turn on WiFi it works instantly.
When I say usually, thats like 60-90% of the time maybe?
Some of these things actually worked better before the update.
I chat with more people from Sweden with Omnia 7 that are having exact same problems.
(We are also the same people thats been having serious call problems with dropped calls, robot voices and bad call quality. (We have a thread soon reaching 700 posts about that on Swedish Telia forum, started in february, thats how long we have been at it with this on our provider and Samsung, and still not fixed))
Samsung Omnia 7 is really unusable on some networks and by the looks of things Samsung doesnt know how to fix it.
Im just so damn sick of this ****.
It would be nice if Mods didnt move this thread so we can see if any other OEM have any similar problems, thank you.
I'm using an Omnia 7 in Singapore and have not faced the problems you mentioned. You may want to try Samsung's Network Profile tool and reselect your carrier to reset 3G settings.
Yes the Omnia 7 works just great on some networks, if we switch to Three the problems pretty much goes away. This would indicate that there is something wrong with Telia but they have also tested everything and there is no other phone having these problems.
Believe me we have tried everything, we have had our devices at Samsung Service Centers and they have installed "special" firmwares for us etc but nothing solves the issues.
No problems with my Omnia 7 in Australia. It does sound like a carrier issue, honestly. Does internet browsing using 3G work?
There is no point in saying you dont have the problems, we know there are lots of happy Omnia 7 users out there.
But the fact remains the phone doesnt work on some networks.
Here is the old list (taken from the Omnia7-forum) of carriers where users have reported the same issues.
A1 Telekom - Austria
Proximus - Belgium
Mobistar - Belgium
Base - Belgium
Singtel - Singapore
T-mobile - Netherlands
Virgin Mobile - France
Bouygues - France
T-mobile - Germany
T-Mobile - US
Vodafone - Italy
Telenor - Norway
ERA - Poland
Simobil - Slovenia
Keep in mind the list is 6 months old so things might have changed in some places...
It would be interesting to know if VoodooKing is on Singtel?
Change to different carrier? If Telia sucks so bad wouldn't it be logical to change to something else?

Its my employer that uses Telia, I cant change it.
And its not Telia that sucks, telia has the best coverage in Sweden bar none, so its Samsung that sucks and as soon as Nokia delivers and my employer gives me green light to get a new phone this piece of **** goes straight into the wall.
it sucks to hear that your omnia 7 is experiencing these terrible bugs
mine's working perfectly though. omnia 7, not branded, philippines
Mine has the problem of not getting a data connection when I turn it on/off.
I have to end up turning the entire phone off, then back on with data on. That's the only way it'll work 100% of the time.
It does however work at times, but very rarely.
There is a rumour going that Samsung will release a fix for these issues in October.
I'l believe it when I see it though, seeing that we have been complaining to them since february. But maybe the Mango release has given them new energy or whatever?
Crossing fingers here.
I'm having the exact same issues with my Omnia 7 since switching to Telia from Three a few weeks ago.
This might sound absurd and in wrong thread but...
I seem to face same issues with HTC Titan on Giffgaff (uses O2 in the UK).
Could it be the way OS is laid on phones?
I have an omnia7 and a hd7
with the hd7 I don't have any problems with 02 DE
with the omnia7 3g suckes big time , internet not working and MP downloads are working so I know I have 3g but still if I try to IE It don't work

I have the same devices but I don´t have any problems with T-Mobile Germany.
BTW I thought you have sent your HD7 to our all Heathcliff74 ?
Some weeks ago I offered him to send my HD7 via mail too but he didn´t accept my offer because of the risk that the device could get broken for some reasons.
Same issues here, TMobile NL.
Problems keeping/establishing WiFi connection and problems keeping 3G connection. Sometimes have to reset to make it work or airplane mode on/off otherwise full 3g+ bars but no Internet...
Here in holland the 3g coverage is nearly perfect (delft/den haag) and I barely have death spots. Mago improved it, but did not fix it. After a while the device just gets cut off the network. And wifi disables when locked, when unlocking it struggles to reestablish.
The only problem I'm facing is that sometimes sound disappears during phonecalls while the connection
is still in place. I'm on vodafone nl, but this problem is a well known problem with the omnia 7. I used to
have HTC trophy and never experienced this problem. For me this was the last Samsung phone, as with the
last Samsung phones/tabs I had, I experienced nothing but problems and s##t support.

you might want to consider using the diagnosis app to set your connection to a particular band
*#2263# under the diagnosis application will bring up the band selection menu
I used to have the problem of the phone always taking a longer time to get data connection mode. But that was fixed after just a simple move of limiting what the bands the phone would search for to have data connection.
Sent from my OMNIA7 using Board Express
I have never had any issues, I'm using Telia too. Works fine here.

tnx for your tip. I have change from automatic to gsm mode and to 900/1800 gsm band (Germany/Europa) for now it seems to solve this annoying problem- i will post a feedback after test few days ...

Thanks for this, but Im not able to select 900/1800/2100 which is what I need since our 3g is on 2100 (Netherlands) so if I select 900/1800 ill lose 3g... which is not worth it of course

[Q] Connection blocked by the provider?

Hi guys... Im from Panama and i have a question let tell a little background
Here in Panama we have 2 providers that have LTE and uses band 28 this is why i bought my zenfone from taiwan with band 28 reception... this is the problem i put my sim card from one of the provider and guess what didnt got LTE and they told me is becuase is my phone that is not allow in their network (they are selling phone which is LTE ready according to them) But i friend of my put his simcard of his samsung S6 from the second company (uses the same 28 band) and my phone got LTE rightaway... So is somthing the provider can do to stop phones coming from outside getting LTE? Right now my phone is getting HSPA+ that is H+ but nothing else
And in the screenshot my phone is detecting the network which is the first LTE that you see. The second LTE with Forbidden is from the other company from which my friend have his simcard..
Thanks for the help

mmm, should you probe further to your Service provider on why it is not allow, could it be that your version was the TD-LTE? which only china has? they use difference accessing method.
the possibility of SP locking the network base on phone is rare as they need to spend extra server to cater for such banning and this does not goes into their profit and Ike customer in general. It could also be that your sim card does not have LTE function. this function is stored in HSS ( HLR) where all your services are known in the network.
Check further then post here. seem to me it is more of your sim account issue.
i post tomorrow im going to talk to my provider and hear what they have to say
Thanks for the interest

Hi good evening , well i came back and I talk to my provider this time the guy told me that my phone should work withouth any problem since it uses the same LTE band as they do which is band 28. He told me that aparently they have to activate something in their network in order for my phone to get LTE signal so they will be calling me tomorrow to tell me if I need to do somthing else. I ask him if i need to use a contract or if prepaid work too. And he told me that it also work with a prepaid service. He told me that my simcard is LTE ready and should not have any problems but told me that they will investigate. Also they dont use TD-LTE.
I will post a soon as I have the answer from them

dont trust your telecom, some truth are not allow to tell customer about, i work for 7 years for 2 different telecom.
if your phone is TD-LTE, you can never connect to your network no matter what, just see it as a door with a wrong key
if it is FD-LTE, it is most likely the settings on your profile is not provisioned, the Customer service may tell you they see it is up but in fact the system that they are reading the data from MAY not be unified with the back-end servers.
It may also because someone in-experience have wrongly provision your SIM profile.
Lastly it could be then handset is faulty with LTE service.
the best way is to call up the telecom with another phone and proposed a testing right when he/she is attending to you. ask them to forward the testing time/ MSISDN to the supporting engineering for wireshark trace. they CAN straight away tell you what problem you encounter.
you are at least someone in the forum that listen and understand truth. some others in another part of the forum are stubborn as hell..
hope you gotten the FD phone and it works for you.

Thank you very much for all these usefull information you are giving me that you gain from your expirience I really apriciate all your help and kwoledge and this will help me explain my self better when i have to talk with them.
I came here becuase there a lots of thing i still need to learn about telecomunication and bands in general (Im actually studing medicine but this calls my attention)
Well i im sure that I got a FD phone because with the second telecom (the one that my friend uses) my phone got the LTE right away so im sure thats not the problem and becuase it got LTE im sure that my phone is working all good.
Since the phone is FD then the most like thing is happening is that they havent afiliate the services correctly (that what the guy from the telecome told me) and that technicians will set up that in their side. They will call me tomorrow and tell me whats happening.
He also told me that aparently there have to be a second registration of the data service which is the one for the LTE that hasnt been done and this could be the reason of the problem.
The only thing is about the testing you you are telling me. Let me see if a got it right. Tell them to foward the time/MSISDN (its the phone numer) to engineering to wireshark trace (this is for looking that the connection and the setups are correct and the case they are not then look where is the problem if in their side or my side)
Again thank you very much. Really apriciate your help and im came here to learn and maybe some else with the same problem have the answer here
Good night

let me put it in this way
1) call up your telco and during the call,tell them that you will be performing a test for packet transfer on your phone now.
2) just try to manually connect to their LTE network by search.
3) let them know the time range that you are doing this (eg. 14:00 to 14:05)
4) get them to let the back end engineer do his/her work tracing > SGSN signalling > DPD context.
5) wait till they come back with you on the details why is it not working for you.
the handset send a signal to the radio (UTRAN) and request a data service (LTE), in this case it the radio will forward this request to the SGSN to S Gateway( just take it as signalling module), if everything is okay, it will inform the UTRAN ok to set up tunnel (in layman context, it is the traffic medium) > so P Gateway will directly link from user UTRAN to it and out to the web via PDP context.
hope this is not heavy for you, in between there are firewalls which the network engineer is able to pick up where the data is dropping for your case.
oh i see that you are going to be a medical personnel, all you need to know is that radio are everywhere and there are some instrument that is using certain band of frequency which will interupt (crosstalk) to your instrument.
the normal cases are WiFi band as it is under free band and medical usage.
For cellular, it does not matter. the reason why hospital ban it in sensitive area is because folks in the older days are using analog signal for transmission (ASK,FSK,PSK) these are to determine the data status of any radio instrument. however nowadays, we no longer use them and systems are all digitized. so it doesnt matter if you broadcast radio in sensitive room because we are using higher tech like QAM64 etc.
lastly the reason why medical still insisted that no radio in the sensitive room is all because... changing of something might affect something else, even if they know what i said, they worry that other stuff might complicate. look at Airport during flight, it is the same reason, handphone can switch on during flight but they say no. its the same reason.
The top management knows nothing and the engineers is reluctance to set things right, too much work to do.
you can read more into those, i know pilot also need to learn about these too!
hi good night im still waiting for them to reply so i think they will call me on monday. When i contact them ill ask them to do this test you are telling me and ill get back with you as soon as i have results.. Thanks and have a good night
hello a came back and with good news. The lady sold me the wrong sim card and they also had to activate LTE services. Now everything its working great thanks for the help sooty84.
Right now im getting 25Megabites pes sec down 20 megabite up i think its because LTE network is new
I think this can be mark with resolve
Hey great! glad to help
