3G sim works but no GPRS

I can make calls with a 3G sim as the 3G network switches to o2 when it is unable to recieve a 3G signal, but I cant get GPRS to work, can any one help? has any one got a 3G sim to fully work with their XDAII?
I will post more info if required
Thanks
Jud

If im not mistaking, the data trafic is locked to a specifik 3G network?

if it were me i would ask 3 if they support grps
and if they did to turn it on

AFAIK, if you are a Three customer, all of their services are available in proper 'Three' coverage areas.
BUT, they make it clear on their site, that in none Three coverage areas, coverage is then provided by O2 under a 'roaming' agreement Three have with them.
They point out that in these conditions, voice calls and sms are still possible (as this uses standard GSM, or rather CSD).
BUT, that picture messaging etc will not be possible.
This seems to indicate quite clearly, this is because a GPRS arrangement with them is not possible, or established.
Thus, in your case, a Three SIM card will work in an XDA (but only the OLDER ones allegedly, Three supposedly got sick of too many people buying them for just the high amount of free inclusive minutes and sticking them in their own handsets and incurring high roaming costs for Three with O2, so locked the newer ones), but GPRS is not available when in a none 3G handset, or in truth, on a none Three network!

Hi
Im on a Three network in Australia and i am able to use the three sim in my XDA however, I am unable to send sms as it cant read the sms function from the carrier sim. I have change to an optus sim and sms works on that, so im sure its just three's sim that doesnt.
Anyone having a similar problem ? and have a fix ?

Hi, I have Austrian 3 sim in my XDA II and GPRS works, however (of course) I am using national roaming partner's (A1) network, because XDA does not have UMTS radio.
Everything works OK. data, sms, email....

[solved] GSMbeam dopod problem

If there is anyone who owns a dopod 838 I need help. I need to know if GSMbeam works when you are using an ordinary gsm sim in your dopod. I don't care if the dopod is doing the sending or receiving, just that you are on a normal gsm network. I can't test myself because since I bough my 838, I transfered my number. Until I buy a new prepaid gsm sim I am stuck.

Give us a call.

SecureGSM see my pm. You must have encounted this problem. I have called three and tried to varify if they support umts csd but I am less than confident the modem support tech guy even knows what I am talking about. He said it is not supported but only after I sloooooowly explained what it is. The thing that bothers me is that my remaining gsm sim gives unreachable from the dopod in the same time as the 3g one. It should take a bit longer. I think the dopod is not realy doing anything when I use LINEMEDIAMODE_DATAMODEM. I have tried to use a plian LINEMEDIAMODE_INTERACTIVEVOICE call and that dose get through, I then do lineSetMediaMode(hCall,LINEMEDIAMODE_DATAMODEM) with both ends before using the call but it makes no difference as it is not supported.
Without LINEMEDIAMODE_DATAMODEM no negotiation takes place and even though on the sending side write attempts return success it dose not work.

CSD is not supported by carriers on 3G networks.
Please see for details:
http://www.securegsm.com/pages.php?pageid=85

Thanks for that cab, impressive. It is much better seeing the manual band options! The problem may well be with the 3g provider but I suspect that my regular gsm functionality is also not working on my dopod. In a few hours I will have another gsm sim and I will use the manual settings with that sim to test.

Using the cab from SecureGSM it is now possible to configure my dopod to work correctly with GSMbeam. I did vodafone to vodafone and it was smooth. I was also able to configure my 3g provider to put me into roaming mode using gsm bands but unfortunately no data call (csd) would go through. The bands tab did however disapear after resetting a few times and the cab needed to be reapplied.
next step- find how to use dual sim, setup call forwarding from my 3g number to my gsm number.
Thanks again SecureGSM!

EDGE & GPRS on call

Hey all,
As far as I understand; when you are on GPRS you can't make a call or receive because it ties up the line.
Does the same apply with EDGE? I don't think it does with 3G but my network just went EDGE over GPRS (o2) so I wondered about the 'new' technology.
Thanks for the advice

it dont apply to any of them unless thats a limit of the phone company one is connected because they have limited equipment

I always thought it did; I used to be Vodafone UK; I started on one of there GPRS phones & couldn't attempt or rec calls, I then moved up to 3G, again on Vodafone & I could run 2 sessions of them easy. It would't be to do with the 3G networks having there own network settings? for example, the 3G phone would give me the option to connect to 2G or 3G when I first turn it on or change networks.

i use GPRS it dont block anything for me
only tech which really block 100% is the old callup modem data calls
which also only operate at something like 9600Boud

GPRS Data Call
Hello, i´ve been trying to find an answer to a problem while calling through GPRS with VoIP using WM6VoIP.cab released here in xda-developers. I can make the call, it rings in the other side, but no sound for either users... There is no sound at all, like if the phone was off. On the other hand, i use the same system to call while connected to a WiFi Lan, and it works perfectly! What could be happenning to me? I use Vodafone, and i´ve also tried it with Yoigo which uses Vodafone network...
I´d really appreciate your help!

GPRS and EDGE are basically the same thing with respect to blocking voice calls.
Old GPRS implementations (can't remember which class - wikipedia is your friend) would block incoming calls - but newer implementations shouldn't. The only thing is when you have active calls, GPRS is suspended.
But I heard that the radio firmwares and equipment of the telco would make a difference.

When I had my Treo 750, I always had a GPRS connection. If there was any data activity going on, incoming calls would go to voicemail. Very irritating, especially when using Direct Push for email.
With my old Blackberry Pearl, and my new Tilt, I always have an EDGE connection, and do not have the issue.
Hope this helps...

[Q] A stupid question: Is Samsung Tab a Phone?

Hi,
please allow me to ask this stupid question
according to the spec, it supports GSM network, does it mean I can insert my normal phone SIM card to it and make phone call?
I don't really want to have a data plan and simply just use my normal SIM card (if it's possible), and then use WIFI when access is possible (at home or in the office).
I am very curious if I can make phone call with it, so I don't have to use my current phone anymore
thanks

It would help if you did a bit of research into the product you intend on purchasing, as any review will tell you, the galaxy tab IS a phone.
If you have an EU model, it will support and allow phone calls.
CANADA ones I think you can make calls, but not out of the box.
US models do NOT support phone calls (Skype may work?)
ASIA Models seem to come without marketplace.

risp is partially right in regards to the USA models (T-mobile / AT&T) out of the box these 2 tabs are not able to make phone calls just use 3G, but if you flash a Euro Rom it will allow you to make phone calls, and you can get Edge (only using an AT&T or Simple Mobile Sim) on both AT&T and T-mobile tabs. Since you stated that you will use wifi either at home or office then you can choose either one of the two and just flash the Euro Rom and you will be set to make phone calls.

OK, I just called Rogers (a Canada carrier), it surprises me that the staff told me it cannot make phone calls. The GSM network only supports the data.
when you said flashing a different Rom can make phone calls, does it mean, the Canada or US model doesn't come with that software to make phone calls?
I haven't seen the device myself yet, is there a place I can insert a SIM card to it, and the device and recognize it? If yes, I am sure there is a way to use it.

It IS an do-it-all marvel
It is a one-unit that does-it-all (including voice calls) if you are anywhere but North America.
Here, the service providers are only offering units with the voice call capability locked out. Apparently want us to carry around two units, a tab and a phone like in the iWorld. Hum. Why? Could it be they want to get deeper in our pockets?
I have a regional service provider that that doesn't sell the Tab. But they promised me if I bought one from the UK (Clove Technology) and put their sim card from my old phone in it, they would give me both voice and data service. Very reasonable.
They don't "support" it but the local staff was so excited to get their hands on it and and play that they had me up and functioning in seconds.
I'm very pleased with it and don't see any reason why any provider that offers voice and data service on your current phone wouldn't be willing to let you pay them for the same service on an unlocked, fully functional Tab that you got from wherever.

T-Mobile is filtering voice because they don't want it to be looked at as a big smart phone. They want it to be a real iPad competitor so they are doing everything they can to make people believe it isn't just a big smart phone but rather something new. Of course we know it is just a big smart phone and naturally we want to makes calls on it but T-Mobile isn't having any of that.
Same with the other carriers in the US.

I was hoping I could get the galaxy tab to run 3g and also provide voice on ATT. It sounds like either you can get 3g data only, or edge data and voice if you are using an euro rom. Is it possible to get 3g and voice on Att by using a euro rom and jumping through some hoops?
Hoping I can just retire the iphone and switch over to the galaxy tab.
Thanks,
John

The AT&T TAB can do 3G and voice at the same time with the EURO firmware.

I found that thread by searching for the words AT&T and TAB. Stay away from the T-Mobile TAB if your service is through AT&T.

[Q] Use my GSM phone on CDMA network

Hi All,
I want to use my GSM phone on CDMA network.
I know that if my phone does not have a CDMA receiver I cannot use the device itself on the network,
but is there a case (like Apple Peel $70-100) or a companion device (like gmate $65).
So basically, I am looking for CDMA modem that could transfer calls, data, and sms to my GSM phone (Xperia Arc S) or wifi device (Galaxy Player).
Any ideas?

Absolutely not. CDMA networks are highly restricted, and only allow phones in their IMEI database to access the network.

hi!

Hmm...
Well the reverse is possible so long as you have a CDMA phone with global roaming capabilities, but gsm to CDMA is limited by the IMEI, as the person above noted. Rather than asking if you cn get a device to transfer calls (because you could always get a throw away phone and forward calls to your gsm number, though I know or assume that's not what you want), find out wether there is a way to emulate an IMEI for non-CDMA devices.

Then there is another option that I wanted to check - using basic CDMA phone (I have samsung M910) with Android 2.2
and transfer calls over wifi or bluetooth to Xperia Arc S ( Android 4.0 and can be WiFi hotspot).
I found an app called "Phone Link by Funky Android Ltd", but didn't have time to check it yet; it is also in early alpha stage.
I'm wondering if there are more advanced apps to do the same if Phone Link happens to be too buggy?
