Can someone help, I'm confused about how GPRS works.
The situation is, I have a XDA on the O2 network. GPRS works fine in the UK.
I recently went to HK, and it didn't work.
Before I went to HK, I phoned the O2 help line and asked them specifically if I need to make any changes, they said 'NO', it should work without any changes similar to GSM international roaming.
By looking around this forum, its seems to me that information given to me is wrong.
Would it be correct to say that if I take my XDA to another country for a short trip, I need to set up the GPRS dial up to connect to whatever GPRS provider that exist in that country?
In other words, GPRS is not seemless like roaming GSM?
With GSM roaming it uses the SS7 network which all netorks connect to.
GPRS roaming never specified the mechanism to carry roaming traffic (as it was IP and not suitable for carrying over SS7).
Consequently there are about 4 public GRX networks that carry GPRS roaming traffic. For seemless GPRS roaming every operator has to connect to all 4.
O2 only has GPRS roaming agreements with a few operators in a few countries. For instance in France there is only a roaming agreement with SFR, so GPRS does work fine, without any changes in config on SFR only. GPRS roaming to O2 will not work on the other two networks.
O2 may have a GPRS roaming agreement with one operator in HK.
Vodafone will ONLY GPRS roam with other Vodafone group companies.
O2 UK do, indeed, have one agreement for GPRS roaming in Hong Kong. They were correct in saying no settings need changing - you are not connecting to the Hong Kong GGSN, after all.
Did you ask that all international roaming bars be lifted and reboot the unit at least 24 hours in advance of leaving the country?

Does anyone know if there is a way to connect to a normal ISP, using a GSM connection, instead of GPRS. I have data calls on my t-mobile account, but when i set up my isp details and dial it, the XDA tells me the remote computer is not responding, when it blatently is, cos i can dial it using my laptop.
Hi Dave,
If you are UK based T-Mobile have released their GPRS service last week. They have a number of packages including 0.075p per KB or £15 for 10MB.
Its not on their website but their staff know about it.
Simon.
Your settings are wrong. Put the correct settings in. Ask someone who knows what the correct settings are in order to discover the correct settings
Maybe it's not all about wrong settings.
After I tried to connect to O2 using GSM from Danmark last week, I called O2 Germany and they told me it won't work. They have no roaming partner for GPRS in some countries and they disabled the GSM for whatever reason. The old numbers I could use to dial in last year won't work any longer. I get timeout error messages or "The connection you dialed does not answer". (It doesn't say it don't exist!)
Considering to quit O2 and use T-D1 again instead. I am very disappointed by the O2 net coverage.

OK, some networks do not support GSM data, and frequently networks will not have GPRS agreements with other networks in other countries.
Can you register onto Telia? In Denmark I believe they have GSM data @ 9.6kbps
You also need to make sure that your home network enables 'full' GSM data, maybe that's what you meant in your post. If they switched it off ask them ever so politely if they'll turn it back on.
I connect to the net using the wap number which is included in o2 minutes on the 250 package, (the gsm internet number was not included minutes) you can change the number dialled in the connection settings box. also set it to "always dial"
check the number dialled as it puts a prefix depending on country settings etc you also need data enable on your sim which is done thru your gsm provider. Sorry if i'm saying the obvious... hope this is of help
Dave, you need to have T-Mobile enable CSD (Circuit Switched Data), which is off by default. There is no charge to have this enabled.
Hello All,
I am researching purchasing a SPV m1000 for my company to use as a phone and WAP device to check email through our WAP portal. After reading many, many of your postings it sounds like to use GPRS in different countries we will have to change the settings (ie. access points) in each country we visit. Is this correct? Does this become a pain to do? How do you get the settings for each country?
Also I understand that if GPRS is not available you can use WAP using just GSM at 9.6kbps. Do you just dial a number similar to a dial-up to connect to this? How well does it work?
Does GPRS usually work out more cost effictive than data through GSM? Which UK company seems to be the best when using in many different countries?
Thanks for any help,
Daniel
Hello,
The GPRS settings shouldn't change. It depends if your phone provider has roaming agreement worldwide.
I had a french phone provider, Bouyues, who had no agreement, so outside France I was stucked.
Now I am in Switzerland, Swisscom mobile has agreements worldwide and I can get access to WAP without any problem. Of course, it's more expensive... but it works without changing anything.
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....

Hi, I have a jasjar in the UK using the o2 network, i will be going to China in june and would like to use the gprs nextwork there. Could someone tell me what i need to do to set it up? The help desk here keep insisting that my set up should just work, but I've been to China 3 times already and 3 times the gprs network was unavailable to me. What do I need to do?
Thanks
It all depends if O2 has a GPRS roaming agreement with the operator in China. You need to ask O2 this as they may not have GPRS agreements with every operator which they have a voice roaming agreement.
But when you find out what their roaming data charges are I think you'll find it will be far more economic to get a local prepaid SIM if the operator in the region that you are going to has prepaid GPRS. A quick google shows that E-Tong in Shanghai provide this http://home.wangjianshuo.com/archives/20030707_use_gprs_in_shanghai.htm
That's easy. But firstly , would you like to use sim card produced by China?
If you use chinese sim card, the settings are easy.And what's more, it costs only 2$ for a month . Such phone number start with '136.........'.
The roaming will be extremely expensive. So it's better to forget about it.
The best way is buy one local prepaid card. But it's not easy just like saying.
China has two operators, China Mobile and China Unicom. China Unicom doesn't provide the GPRS service but CDMA. So if you want to use GPRS connection, you have to choose China Mobile. And China Mobile has three kinds of branded service, Go-Tone, M-Zone and Shenzhou Xing. The 1st one is only for registered users, so you won't be able to apply it. M-Zone is the prepaid and for sure with GPRS service, the last one may not be able to use GPRS depends on the different region.
But one thing you must pay attention. All prepaid card provided GPRS service is only able to use http connection with proxy. If you just want to browsing the web pages, it should be no problem. But if you want to receive/send email, there is no way.
Settings:
1: Web browsing
APN: CMWAP
Proxy: 10.0.0.172 port:80
2: MMS
APN: CMWAP
Gateway: 10.0.0.172 port:9201

Enjoy it.

Hi dahuzi... thanks for your reply. Is the Go-Tone a contract service with a monthly service charge?...
May I make some amendments to what dahuzi said:
I'm using both Go-zone and M-zone, and both can browse websites and check email. They are 2 types of connection; one is so called cmwap, and one is cmnet. You should use cmnet, which is the normal GPRS connection used worldwide.
The charge is different in different regions. Let's say in Beijing, the charge is RMB 20 (approx. Eur 2.00) for 50Mbs, RMB 100 for 800Mbs.

The above settings is for mobile handset only. You will not be able to use for full intenet usage.
If you intend to use your PDA or PC to access the internet using GPRS. You will require cwnet for full interenet access, and this service only available for locals pay monthly account package only. The service is not available for pay as go customer.
Internet on the move for foreign visitors in China may be confine to Starbucks or some WiFi hotspots.
Anyone who knows the China Mobile CEOs please pass this message to them, we are frustrated with their GPRS services unable to give full interent access for us foreigners.
Well, I was in China during my easter holidays and was very happy to find, after getting my bill, that O2 did not charge a penny for GPRS roaming in China with China mobile. Furthermore there is no need for additional settings on Exec so that everything worked fine and, freely. The GPRS roaming was really perfect; there was no need to buy a SIM from Chinese operators.
I am with an O2 data tariff which accounts for 200M data per month (29.8 pounds inc. tax).
I'm however not sure if it is the same case with Orange but I guess, from my past experience with China Mobile (I used the GPRS service since its open day in CM), it is highly possible to be a free roaming. HOWEVER I AM NOT LIABLE TO ANY MIS-GUESSES so please don't accuse me if I was wrong ..
My service provider is Mobilinkgsm in Pakistan. Last week I visited China. My GPRS worked perfectly there in China. I also sent and received MMS messages without any problem.
I was not required to change any settings for either the GPRS access point nor the MMS settings as my connection with MobilinkGSM Pakistan is set to International Roaming. I have an i-mate Jasjar.
GPRS international roaming rates for Mobilinkgsm Pakistan though are quite high. They charge US$ 0.02 per KB which means almost US$ 20.50 for a MB of Upload + Download data.
Just wanted to share my experience.

Is there any way of knowing in which countries GPRS will work in? I've got a T-Mobile MDA Vario and on one or two occasions I wasn't able to get GPRS up and running in order to browse the net. Just wondering if it doesn't work in some countries or if that was a coincidence.
Isn't there a list of countries/companies which T-Mobile have roaming agreements with on the T-Mobile website ?
Yes but this only indicates where you can use the phone. My understanding is that this does not necessarily include GPRS/data availability or access.
Yes, just because you can roam does not mean you can use GPRS. I do not think that info is on www.gsm.org either. Drop an email to T-Mobile customer service if it isn't on their site.
Must admit I always buy a local SIM for data usage now that many operators have pre-paid GPRS.
GPRS abroad..
T-Mobile do have partners abroad - for the preferred network to use and cheaper calls - but that doesn't mean you will get any of your GPRS allowance wheilst roaming.
I have the Web'n'walk tariff , but my mobile bill was still over £160 when I got back after a week in Eire.
I think the GPRS / MMS data usage was at their standard roaming tariff.,, whatever that is.

Some examples
I couldn't use GPRS with O2 in UK (where T-Mobile wasn't available). I had no trouble with multiple carriers in Barcelona and always found T-Mobile itself in Frankfurt and Bonn. GRPS works in Paris (didn't note the carrier) and never worked with any of NINE partners in Taiwan last year.
prestonmcafee, thanks for the examples. Your visit to the UK must have been some time ago, T-Mobile exists here now, I think they initially came in the market a couple of years back when they acquired what used to be one to one, or whatever they were called.
Yesterday!
Sorry I wasn't clear, what I meant was that I couldn't get GPRS in the UK in the places where T-Mobile wasn't available; T-Mobile is usually available but not always. Victoria Station and Heathrow have places where T-Mobile's signal is so low that the automatic connection on a US T-Mobile phone connects to O2, and in this case, GPRS will fail.
Sometimes, but not usually, a manual connection would turn up T-mobile even when the phone had connected to O2.
I just returned from 5 weeks in the UK yesterday.
