the handset is obvioulsy unlocked and with t-mobile,but when abroad last year with different wm5 roms -no problems everything worked fine,have spoken to t-mobile who are about as much use as a choclate tea pot
1) when trying to connect to internet-it does nothing-if i force the connection and get it use the csd t-mobile -i get 'failed to dial' message
2) when trying to retrive pop3 email(no exchange server involved) get new message about extra charge as roaming and then it try to connect for a spilt second before displaying error syncronising
i can roam all networks pick everything up?
please help people

hello,
I've no probleme with data connection when roaming my provider is SFR (france) and roaming provider is proximus (belgium).
Have you trying with another roaming provider ?

as many as i can try telia,vodafone se ,iq etc etc
no joy-beginning toi think it is to do with t-mobile

also without stating the obvious, as and when i can find a free wifi-everything works

are you having prob only with your data connection?? back in uk (?) were you using 3g or gprs and lastly in setting/phone/ is the band set to wcdma (3g) or gprs

in uk had set data to auto all have tried every over type- but still does not explain why it worked seamless before -it either is something within the wm6 rom(i doubt) or t-mobile(proable)
but as i m traveling as soon as i get back i would like to get to the bottom of it.

It may not be your Universal - it may be your provider
Did you inform T-Mobile that you were going overseas? They need to activate international roaming on your account...
I've seen this problem before (working in a phone shop and all...), a customer from country xxxxx can't make\receive calls - because international roaming is not active on their account

Roaming worked on WM5, now not on WM6
Hi
I had similar problems. While Roaming previously (From SA (MTN), roaming in Mauritius (on Cellplus and Emtel) under WM5, I had no problems with SMS (text) or data calls.
Recently upgraded to WM6 (Laurentius' V7 VideoCall) and when landing in Mauritius last week, I could not send SMS(text) or connect data. It picked up the network. I did not test normal voice calls, since I usually dont make any while roaming. I simply used my sim card in a different handset for the week, but it was very frustrating, since Ive come to rely heavily on data access while travelling overseas (for email, skype, etc)

Could also be Radio Ver
Hi all, Could you all edit your posts and enter your Radio SStack Ver ?
And if you can remember what Ver you were on when it used to work on WM5.
As stated in the post, the 1.18 Stack had updates for roaming, I haven't had a chance to test it myself, could anyone provide feedback on roaming with 1.18.
Cheers,
Beast

dark force(excellent) and radio 1.15 will try upgrade as leave country in a few weeks

I roam between China, Hong Kong and Taiwan a lot. It appears data works better with some local service providers only. So what I do is when travelling to a new place, know which local providers data network 'roams' better with my China Mobile, by manually selecting, and trying, one by one, on the phone control panel, network selection part. Once I found one that worked, then I manually fix to that one.
Now everytime I travel to a different region, I just do, phone control panel->network->manual-> choose the known good one.
I hope this works in your situation and network providers.

[Q] Network problems with I9000 bought in Singapore, using in Canada

Hi everyone,
I bought a Samsung Galaxy S GT-I9000 (16gb) in Singapore and was using it fine on Singtel's network (signed a contract with them). Now I have moved back to Canada and brought my phone with me assuming that all would be ok to use it with the network here. However I'm having big problems with this one network I just signed up with (Virgin Mobile).
85% of the time I cannot connect to it: voice calls and SMSing won't work nor will the data work on it, the only thing it says is "Emergency calls only". Then at other times everything will seem to connect and work fine - I can make calls and use data.
Virgin Mobile will not support me much because they're thinking it's the phone's problem, if I use the phone they gave me (a lower-end model) it works fine.
Here are some details of my phone:
Firmware version
2 2
Baseband version
I9000DXJPA
Kernel version
2 6 32 9
root (at) SE-S604 #1
Build number
FROYO DXJPA
If I check out the status, it usually says this:
Network
Unknown (switches to VIRGIN when it does work)
Mobile network type
UMTS (switches between that and HSDPA and GPRS)
Service state
Out of service
Mobile network state
Disconnected (switches to connected when working, and even when it's not working sometimes)
I have Network mode set to auto mode (GSM/WCDMA). I've tried to switch it to GSM only but that didn't seem to change anything.
I'm wondering if there's some kind of configuration settings I still need to do with the phone? I'm also wondering if it is the network I'm with right now? Virgin Mobile isn't one of the bigger telcom companies here and I'm thinking that if I switch to one of the bigger telcoms, will it work better?
Something else to add - before I signed up with Virgin I was using my phone with a pre-paid service (called Chatr) for voice only and it was working fine.
I'm sure this phone can support the GSM frequencies here.. can't it?
I also still have the Singtel customizations on the phone. Will it help if I remove it?
Any help would be greatly appreciated!
Thanks a lot!

sorry, wrong category..

[Q] Cannot Connect to 3g with the Correct APN settings?

Hi All,
A few weeks ago I bought the Euro Xoom 3g and of course try to use the internet.
Problem in short:
The Vodafone Sim i use does not work with 3g on the Xoom. It borrowed the sim from my HTC Legend ( on which 3g works perfectly ).
More info:
APN settings i used are:
- Same on Legend (with CW7)
- Original Xoom (NL Vodafone)
- The settings received from Vodafone themselves.
Same symptoms in Rooted and unrooted Xoom
Model MZ601 Build:H.6.1-38-1
GSM network is functional ( even get text messages about missed calls )
Attached is a logcat from the radio while the xoom tries to connect, with a few things i noticed ( but do not really understand ) mentioned below:
GPRS CSS not supported / UMTS CSS not supported
[0388]< REQUEST_GET_NEIGHBORING_CELL_IDS error: com.android.internal.telephony.CommandException: REQUEST_NOT_SUPPORTED
Things i read from other forums ( like tweakers.net ) are:
Update 12jun, other provider sim i lent (kpn) worked like a charm.
- Users with other providers (KPN/T-Mobile) do not get such issues.
- Some users (and i ) call/visit Vodafone but only get the "Is the APN set up correctly" without any luck reconfiguring.
- The neighbouring cell message could relate to incorrect programming ( read in custom rom forum topics )
Can any help help me to analyze what is going wrong, if this is something fixable in the software or anything else?
Thanks in advance and for reading upto this part of the message.

Help!

Was this ever fixed? I've got a Motorola Xoom (picked it up on clearance for cheap!) and I live in Australia. Optus, Crazy Johns, Boost, Vodafone etc ALL work fine with the correct APNs and do at least detect the network, whereas Virgin (the sim I'm using) does not.
I know the sim works, as I've tried it in other devices (android AND iOS) with the same APN settings, and I know the device works (on other networks) so it's not locked...
I'm at my wits end here!

That looks like a solution... I'll try that if the Motorola guys haven't heard of the issue before and don't have a solution (I've got a couple of reps looking into it, should know by tomorrow)
Cheers!

trying to use a Japanese sim in on originally USA galaxy s5

I came to Japan after speaking0 to sprint about the possibility of using a Japanese SIM card in my phone. They said there'd be no problems I'll just have to unlock the phone before I left which was a completely doable thing by myself without their help. Now once I set up the Japanese sim I can make calls and text but have no access to LTE on my phone. Whenever I'm outside of Wi-Fi range I get a message saying mobile data connection could not be established LTE: ESM - 30 EMM - X I've called Sprint from Japan and tried to resolve the issue, they have walk me through the same steps three different times assuring me that the phone is unlocked on their end and never with a new result. Is there something that I missing it I need to address before I can connect for mobile data connection in Japan with this USA phone.

Is it possible for Pixel/Pixel XL to use China telecom LTE and make phone calls?

Hey I recently purchased Pixel XL from store.google.com and had it shipped to California and took it to Shanghai, China. After inserting the china telecom sim card, i found that I can only make/receive phone calls but cannot connect to LTE network.
It is clear that the hardware does support the china telecome LTE network. I even find a small tutorial of switching to a mode where I can use LTE network but cannot make phone calls.
Dial *#*#4636#*#*
on the upper right cornor , choose United States
in the middle of the screen choose CDMA AUTO (PRL)
turn on Airplane mode and then off
Then I can find LTE signals.
But the phone cannot make phone calls under this mode.​
I'm not sure if I can switch it back to make phone calls mode. And is it possible to solve this problem and make it able to receive phone calls and have LTE network at the same time? Tremendous thanks!! If I can provide any information, please guide me to find the information and I will happily provide!.

Have you tried LATE/CDMA/UMTS auto (PRL) mode?
I could imagine that this let's you use both, China mobile LATE (which obviously needs the CDMA mode) as well as UMTS as fallback for calls.

Currently a file(carrier_policy.xml in the EFS partition of Pixel 2 series and probably Pixel 2016s) lacks proper configuration for China Telecom with its LTE network using SRLTE (which is a common practise of establishing the CDMA and LTE network at the same time).
Thus the team can and should fix it by:
Adding the following 2 strings(in red) to the carrier_policy.xml in the EFS partition as follows:
......
<!-- List of the MCCs in which SRLTE is allowed -->
<mcc_list name="sxlte_mccs"> 455 460 </mcc_list>
<!-- These are the serving system PLMNs for which SRLTE will be allowed
-->
<!-- NOTE: Proper functioning of the SRLTE policy requires that there
be an PLMN list named "sxlte_plmns". Do NOT rename this list.
-->
<plmn_list name = "sxlte_plmns">
455-02 455-07 460-03 460-11
</plmn_list>
......
