XDA II Roaming in the US

I have a strange problem!
I have an O2 XDA II, (unlocked), original ROM (1.03 USA), which I'm using with a UK Vodafone SIM. This works fine in the UK, however I am currently in the US trying to roam, without any luck. The automatic network selection does not connect to any network. Using manual network selection, I can select the T-mobile network, which it connects to, with good signal strength, but if I try to make or receive a call it does not work. It also loses the connection altogether after a few minutes. (This SIM works fine in the US in my Motorola tri-band phone). However, if I use my wife's US T-mobile SIM in the XDA II instead of mine, it works fine!
Any ideas?? All help would be gratefully appreciated!

phone networks must have agreements to let users roam

Vodafone certainly have a roming agreement with T-mobile in the US - I've been using this SIM in a triband phone in the US for years.
Paul

well are you talking about roaming of grps ?
because there are not as many agreements when it comes to grps as there is when it comes to std phone

No, just roaming GSM voice!

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....

3G + Universal + Australia

Hi,
Could those Universal owners in Australia response to this thread with...
a) What provider they are with
b) What plan they are on
c) The procedure for configuring their unit with their provider (to this point of surfing the net on mobile broadband.
Rather than trial and error I thought I'd try and cheat and just ask someone who's gone through all the pain already.
I would also be interested to hear comparisons between plans and providers.
Regards
Michael

I'm interested too! I've been looking on the net at Telstra, Optus, Vodafone and Three but I can't see anything really great - all very exy!!
Most are linked with phones on plans - not good for us we've already got the unit.
I want a sim only plan that gives me reasonable rates for data download.

I'm using Three - gave the bundled phone to a friend who wanted to upgrade an old NEC. $99 Cap Plan includes $15 towards data usage, but i've never managed to get past the $99 cap yet.
The data speed is fast - to get 3G you need to create a new connection, set the AccessPoint, which is "3netaccess", and leave all others blank. Roams to Telstra GPRS when out of coverage in Oz.
Don't bother with Three if you go overseas - there's no data coverage outside Australia for Australian customers.
There is also no comprehensible FAQ on their site for the MMS setup - just lots of pages with "your phone comes preconfigured - don't change it" comments. Ringing support is no good, if you try to, they soon figure out you are not using "their" phone, and can't help you.
If anyone else here has MMS working please give the settings.

Telstra Universal on 3G
I purchased my JasJar in the UK on a business trip, and with my UK Vodafone SIM had 3G working fine.
For Telstra 3G you need a new USIM for 3G - they should supply for free if you're a post-paid customer.
It actually roams onto the joing 3/Telstra network and drops back to Telstra GPRS.
The Telstra settings are simple - telstra.internet for the APN
Also, the 3G data plans are more generous - I changed from $55/month 5MB plan to a 3G $15/month 6MB plan.
All seems to be working fine.

I have the JJ and use Telstra. The process was simple, Tell my secretary to give it to me, TElstra call me back and say that I have it, use the Imate auto configure to install it and of I go.
Expensive yes, but in the overall scheme of my business costs, its not worth looking at. Telstra I believe have a special for the video call bit that they charge the same for a video call as they do for a mobile phone call, to get you to join and try it. I dont have anybody interested in video calls.
I didnt need a telstra sim to do this, and havent actually tested it for videos.
I only really use it a little bit for internet connectivity, and given that I have wireless networks at home and office, I dont use the GPRS to 3G connectivity much.
Heads up though and it is posted in these forums elsewhere that phone companies (and I suspect telstra) would limit it your speeds to the minimum required for video conferencing which is 128kb ps, whereas 3G networks are capable of 384kbps, and only switch it on when you ask for it.
I really dont have that much need, and it doesnt even come close to the capabilities and speeds, ease, costs and overall benefits of the ADSL wireless network.

Hi, I sold my Universal (O2 Xda Exec unlocked) to somebody on eBay who lives in Melbourne, Australia.
Today I received this e-mail from him after he received it:
"My sim card doesn't work."invalid or missing sim card" appears.Can you help me to figure out."
Any ideas anyone?
PS: I should add that mine was one of the 1st Execs shipped in December and was definately unlocked as I had it working with O2 and Orange. All I have changed is to install the new Extended ROM update from their web site, which I presume doesn't have SIM locking does it?
PPS: Update from user: "Thanks for your response.Australia has got a couple network. I currently use $49 cap plan Optus network. but I don't have any idea about frequency."

my friend had a problem with optusnet, told it was the phone!!
I put my telstra sim in, worked perfectly the first time.
went to optus, requested a new sim, got it tested it didn't work, logged a support call, waited for call back, tried agin with support, nothing returned, got a telstra sim the next day and never looked back...
moral, optusnet support sucks when they don't sell you a phone, the knoledge is limited and competency sucks.
BUT I do use them for adsl, and home phone, even then acknowledge that they suck.
Tell your customer to test it on a friends telstra card and run the telstra cab, its something in optusnet.
by the way, my friends phone wa the imate jam / xda mini so the problems hadn't even started with the 3g network of the exec.
my jasjar works perfectly on telstra.
pm me, or get your customer onto the forum if I can provide localised help.

Thanks. Can you please clarify what you mean by "run the telstra cab, its something in optusnet"? What is a 'cab'?
Are they the same network and would he be able to retain his account, or does he have to switch networks?

Networks in Australia
Although Optus and Vodafone in Australia actually share a 3G network (3G air interface) everything beyond that is separate so for billing etc your friend would need a new SIM card. It's likely thet Optus people did not sell him a 3G SIM card - they will have to tell them what it is for so they give him the right SIM.
In OZ, Telstra share with 3 so you 'roam' onto the 3 network for 3G even though you have a Telstra SIM

the cab file is located on the extended rom, or on the 02 website, or the imate website, I have also posted the file elsewhere on this forum if you look for telstra.
if you cant find it, i can locate it and post it, just dont have it handy now.
a cab file installs programs or settings to a device. this particular one sets up all the mms, phone and 3 g settings. if he did a hard reset, the phone itself would ask him his communications provider and do this automatically. but telstra can only be used on telstra, and optus on optus networks, and they are effectively strings of commands to access gprs, 3g, and wap sites.
he may not have run the setup correctly on this. if he installs total commander, and types into the address field \extended_rom\ he would be able to locate the file on the device already and just run it to establish his correct settings.
however, i feel it is likely that the sim card is dud.

Hi all, thanks for your previous help. The customer now has a new SIM from Optus, Australia, which works great for calls.
However, he cannot set up GPRS. He states:
"I tried everything to set up gprs setting.I couldn't.I check the my friend's xda ii series gprs setting.It has got auto config option.So it does itself.But my xda exec ask me phone number ,domain name,username password,dns setting etc.
I rang to Optus technical support.They told me they don't support this one.They gave me dns number but didn't work. But I think . if xda ii works, exec should work.I just need set up for Australia. Please help me."
Does anyone have a link to an Optus Australia auto-config util that will send him the config in a magic SMS?
Failing that, can you type all the details here or provide a link to the Optus cab?

I'm with Vodafone on a $79 cap. The cap value includes data ($1/5min), but the billing by time rather than downloads might not suit most people.
As for configuring the phone - I just downloaded the operator settings CAB file from clubimate.com. Sets up everything perfectly!
AFIK, Vodafone and Optus are the only ones that will offer Sim-only 3G plans. Of course, you can go with Three, and just discard the phone (you can get a free phone on a $29 cap!)

JJ on Three network
JJ on Three network.
I'm going to check this post and report in the near future:
http://aussie3g.com/modules.php?name=Forums&file=viewtopic&t=16121&highlight=jasjar+3netaccess

telstra also offer 3g plans, but I use their phone network and sim card as part of our corporate plan.
I have sent the customer the std cab file on my imate rom, which he reports was not beneficial for him.
I am not on optus so don't actually have the configuration settings.

i never tried data, but videocalls worked fine...the only limitation being it only works on the overseas 3 network (3 - Hong Kong in my case, this was 2 years ago when i still lived in brisbane)

It's okay guys, Optus were giving him wrong details. He found the right ones -- they're all over Google

VOIP Calls on T-MOBILE (UK) 3g network using HD2

I have found problems while making VOIP calls using SIP (soft phone) software on t-mobile, UK 3g network.
I got various sip client installed my HTC HD2. They all are working very well on wifi connection. But not working at all on t-mobile UK 3g network. I get registration failed error.
I found following link (https://www.t-mobile.co.uk/shop/terms-and-conditions/combi/) in which they have mentioned that
<b>
"you can't use your phone as a modem or use internet Plus for peer to peer file sharing, or making internet phone calls. *[Internet] Plus comes with a fair use policy of 3GB a month."</b>
So I am wondering whether T-mobile is blocking my access to connect to my VOIP provider. Although, I can use skype mobile on t-mobile 3g network to make skype to skype calls.
Guys,
Is there anyone who is able to make VOIP call using t-mobile, uk 3g network or any of the other UK provider? If yes, then please help me to figure out what’s wrong in my settings.
Thanks.

As many people have found on T-Mobile for various data connection problems, , try this
settings/menu/connections/manage existing connections/proxy settings tab/remove the tick in the "this network uses a proxy server to connect to the internet" box.

Already tried this, but no success. So wondering is it possible in UK to make VOIP calls using any 3g network.

Guys Please post your VOIP call experience on UK 3g providers.

You could try getting VPN to work?
It is true that indeed some providers do block certain ports/protocols to enforce their terms of use.
Vodafone NL started with this too some time ago..

I don't use it much but I've had no problems using Skype on 3UK.

I'm with T-Mobile UK and can use Skype without problem on HD2

Vodafone NL blocked some ports

Hi there,
I have also noticed that Vodafone NL has blocked some ports such as for Rapidshare and Megaupload !
Is there a work around for this?
Thanks

hi
I have tried many times with Softphone 3.0 and it does not work. My mate has swapped the sim card into his iphone and with o2 it registered without problems. it seems tmobile is blocking port 5060 for sip connecitions.
Fring somehow works but Softphone is much better, under Wi-Fi it quickly connecter my friend calling me to my Voip-in number (voipcheap). fring can fail with this.
let me know if you have found some clues how to make it work.
thanks

Hi
I am also facing the same problem. I can make jumblo calls( voip provider) if my wifi is connected.
But it does not work with my t-mobile uk 3g connection.
Please advice.
cheers

Wifi calling not available

I have a S10+ that was bought from US Cellular that I am now using on Straight Talk with a TMobile sim. I had Wifi calling working just fine before I switched to the new Beta update. After switching back to Android 9 it now says "This is currently unavailable under the call settings for Wifi calling. I am at a loss. I live in an area were the cellular signal is spotty at best and need Wifi calling to work.
Anyone have any ideas?
Thanks

AT&T doesn't like unlocked phones so it's possible the option isn't showing up because of that. Many AT&T customers with unlocked phones have reported that they needed to contact AT&T customer service to get WiFi Calling or Volte working.
