O2 roaming GPRS not working

Hi,
I got my O2 Orbit a day before leaving the UK for Qatar so didn't get a chance to suss this out before I left.
I'm still running on my O2 sim etc. When I arrived the GPRS doesn't register and the GPRS/internet connections etc all keep asking for a modem setup.
Qtel is the operator here but talking to them about roaming internet/gprs connectivity with an xda is fruitless.
I can't get much help out of O2 either....There's got to be a way, there has to be a way.....
Can anybody help at all? Please?

try this
After two or three trips away with o2 device and lots of calls back to the uk my solution was to go through all available networks one at a time and force the device to try data connections I still need to do this five years on even after telling o2 how to connect

No network UK

Hi Guys,
The problem I have with all networks except in uk t-mobile, the other orange, vodafone, o2. When trying to connect to the o2 message pops up: "unable to connect to this network at this time. Please try again later" on t-mobile grabs network without any problem. The problems began when I came to the UK to Poland was all too dobrze.I change to GSM mode, but without effect only if o2 uk only when I set the GSM (PRL) range but appeared only in the city outside the city it was lost and only work network HSPDA.

I asked the operator if a phone is a phone is not on the blacklist he wrote that everything is ok
I hope that everybody will understand me because I wrote the translate: D
Thanks

Sounds to me like it's network locked to T-mobile UK, try using the sim unlocking tool here. The fact that it will work on t-mobile uk suggests there is nothing wrong with the hardware

[Q] 820 stuck in roaming - (Orange - UK)

Hi,
My girlfriend recently ordered a HTC desire 820, which finally arrived yesterday. I was a little concerned when I noticed all manuals and quick start guide etc was printed in Chinese. Started up the phone - also default language was Chinese.
After setting up and inserting her old Orange SIM card her signal is always showing as with the small "R" for roaming. The Cell towers she connects to reports as EE since EE now owns Orange and t-mobile. but HTC recognises the SIM as Orange.
I've tried manually selecting the network to Orange which removed the roaming for about 30 seconds or less. I gave up and went to bed at this point as it was already time consuming as she did the usual forget every password possible along the way trick! I woke up this morning and asked her to try setting it to 3G only mode, but apparently this didn't help.
I thought perhaps I could flash a new UK CSC to the phone and this would somehow fix the Roaming issue? If this is correct, where can I get the correct CSC for EU/GB? Current firmware version is 1.20.707.2.
Any help is appreciated!

HTC 10 partial vodafone network registration

I have and HTC 10 from Taiwan, which I use in Netherlands. This was working well until the upgrade to Android 7.0. Since then, I get only partial network registration on Vodafone NL.
Nature of the problem:
- Calls and 4g work, SMS does not work.
- Menu selections in calls ("dial 1 for ...", etc.) does not work.
- After coming back from flight mode, calls work, but 4g only works after phone reboot.
- No display of cellular network signal strength.
- Network settings does not show information on cellular network.
- Phone identity does not show IMEI.
Other aspects:
- When roaming in any other country in Europe, there is no problem.
- SIM card of different network (T-Mobile for example) works fine.
I have called both Vodafone NL and HTC NL. Vodafone refers to HTC, which I believe is correct. HTC admitted after some time that there were some complaints, but have not offered any solution so far.
My question is if this is a problem that can be solved on the phone as it is, or should I install a different ROM version?
My current (stock) ROM version is 2.41.709.7 and I have friends in NL with a different (stock) ROM version which works fine, but these are NL phones and I have a TW version which I am not sure if there is any risk for HW incompatibility.
Thanks.

Galaxy Watch Active 2 LTE - Unable to make/receive calls

Hi folks,
I recently bought an Active Watch 2 and already have a Vodafone UK mobile account to which I added the One Number service.
I've discovered that on my watch while on 4G, I cannot make or receive phone calls.
There is definitely a data connection there, as I can send a text message or use the Internet browser app to view a website.
What happens is I dial a number, I get 2 beeps and then a Call Ended message. I've spent over 10 hours on the phone/chat to Vodafone trying to get this resolved to no avail. I've done a number of resets, SIM swaps etc.
This morning I noticed on the watch under Settings in the Phone app, that there is an option for "Preferred Number for Calls" which is greyed out and set to 'Watch'. I'm sure at one point when I first got the watch I was able to select Phone or Watch. Could this have something to do with it? Is the VF network blocking the call because the watch is trying to phone from the One Number secondary number instead of my contract phone number ?
Any help appreciated!

Hey there.
I have the exact same problem myself, my carrier is o2 and have an Active2 LTE.
Set everything up through the esim QR Code. I am the £5 data per month, and yet am unable to make or receive phone calls through LTE / Wi-Fi. No issues though with data and messaging.
It occasionally worked when I first set it up a couple of months ago, but since the latest Tizen update to 5.0 something, there is no option under 'remote connection' in the Galaxy Wearable app to make/receive calls. When testing my original Galaxy Watch out, the call option is there and it is on Tizen 4.0 and I am able to make WiFi calls.
At first I thought the issue was with o2 but am now thinking it is related to Samsung services. Via Bluetooth the Active2 works fine with call functionality but through WiFi/lte, nothing. The odd issue as well, is that, when testing through LTE on the watch it remotely connects very briefly to the phone when attempting the call but then the phone automatically disconnects from remote dialling.
I would say that it is definitely software related, I also have tried all troubleshooting issues and more with no luck.

Hey there. Have you managed to get a fix for this?
I have been in contact with both o2 and Samaunf on this very issue and Samsung are saying to send it in for repairs. I am very dubious though that it is a hardware issue, rather software related.

Hi I have now got both a galaxy watch and a galaxy watch3 here in the UK to now work stand alone on a pay as you go ESIM and wondered if some of my findings may help.....
First the Galaxy Watch i bought second hand on an auction site
it had been on EE in the UK and when i first loaded an esim on it I could not make calls or connect to the network...
I looked under settings connections mobile networks only to find that there was no option to select 3g / 3g4g mode ....
Hence the unit was setup only to connect via 4g data ....by default ....and so would only send Voice calls over LTE ...and hence when i changed the ESIM from EE yo Vodafone I could not make calls or SMS ...and only had emergency calls over vodafone if i was in a 4g service area with no ability to search for or connect to 3g
So I downloaded OXX versions of the firmware instead of OXA for the UK ...and i got the earliest version i could find.
Then loaded it onto the watch ... then I checked the CSC and EE where using a non BTU CSC code so first...
I changed the CSC to BTU so I could support non EE ESIMs
Next I Uploaded an ESIM from Vodafone via Galaxy Wear on a samsung phone over a bluetooth link after first activating
the esim test feature of wear app to enable QT code scanning to load the ESIM.
The OXX firmware activated the 3g 3g-4g section option under settings connections mobile networks so i could enable 4g/3g auto selection .....then the watch could find and connect to 3g or 4g networks and make voice calls and send / recieve sms.
then I put the watch into firmware download mode to install OXA firmware ...and it was an the oldest version i could find
the watch rebooted and so i now had OXA firmware with the 3g-3g/4g toggle still present under settings.
checked it was on 3g-4g auto selection.
then I enabled Dexv mode and made sure the CSC was still on BTU for generic UK ....it wasnt it had changed so I reset it to BTU
then I upgraded the firmware to the latest version via wear app ...
So end up with a generic BTU UK CSC with the latest Firmware BUT with the 3g/4g selection option under mobile networks.
with another service providers ESIM installed 3g/4g to auto select and it all works fine.
hence myadvice is if you dont have 3g/4g then the watch may be locked to 4g ONLY and VOLTE as its only mode with the CDC set to something generic EE for example...
Hope this is of assistance as many conplain that the watch wont work stand alone for voice calls or sms properly
my days of time and many esim tests until i got 3g support and 3g-4g auto load lead mr to think that the watch is often
locked to 4g data and VOLTE only ....
I now have done this on watch and watch 3 models with full sucess stand alone pay as you go esims ....with the watch fully stand alone...working like a normal cell phone ....with esim service with a different provider to the sim in my samsung phone
comment please .... hope that helps

Hi. My problem is different from this. I can make and receive calls from My Active2 LTE and I can also send text messages. However, I cannot receive text messages. Basically I bought this watch to rely on this for calls and messages and this got totally disappointed me.
Any advise on how we can receive text messages?

I have had this problem too. The issue is in phone settings. Go to ADVANCED FEATURES and turn on ALLOW CALLS ON OTHER DEVICES also turn on mobile data in this setting.
