Going to Europe. How to disable data connection and enable wifi only?

I'm going to Germany for a month and do not want to accrue any voice/data charges while I'm there. I plan to use wifi only. What's the best way to disable voice/data, but still use wifi? I also want to make sure that my apps do not try to establish a data connection outside of wifi. One idea I have is to keep the phone in "airplane" mode. But I'm concerned that if I reboot my phone it will kick itself out of airplane mode and start roaming.
Any suggestions?

change the APN settings to point to a non-exsistant server, cell interent wont work but wifi can be on and you can still make/receive calls and SMS if need be

I just got back from Europe, this worked wonders for me.
1. Go to Settings
2. Go to Wireless and Network Settings
3. Go to Mobile Networks
4. Uncheck the Data Roaming Option.
This will prevent your phone from using data while you are roaming.
@dcplaya I am also running on Cin Bell. Works great!

Or get a German SIM, that way you'll have data. If anybody calls you on your US number let them leave a voice mail on Google voice

I have a Nexus One in the UK and have so far taken it to the US, Switzerland, France, NZ and HK. The above definitely works and should be all you need to do. I just had a look at my online balance and can confirm the total on my data charges is £0.00. Note that you can leave this setting disabled the whole time, even when you're in your own country. The phone distinguishes between roaming and non-roaming and acts accordingly.

awesome thx - i came to post this exact question and bam, first thread.

No 3G Network with I9000XWJG5

Hey,
i flashed the I9000XWJG5 Firmware and now i do not get 3g to work. I used an o2 UK Sim and do net get a data connection (before it was always 3g) and no 3g connection with orange too, just gprs.
Has anyone an idea, what i can do?
--- update ---
also only o2 uk sim is edge where before was 3g.
Made a test with my htc hero (Villainrom 12), same place, same sim card and i got 3g.
and 'only 2g' is NOT activated on the samsung galaxy s

You need to configure your mobile operators' APNs.

it is configured properly. so settings are correct. i am not the only one with the problem. i read it on various threads but couldnt find a post with the solution so far.

You're holding it... wait, no, just manually re-enter the APN settings, because flashing firmware will wipe them out. also try factory reset, if that won't help.
3g will popup immediately when you have put in the correct APN settings. Trust me.

As i said with an htc hero, same settings, it works, with the samsung galaxy it doesnt. so i can assume that the settings are correct
htc hero = 3g
samsung galaxy s = 2g

Could it be you are roaming (you see an R with the reception bars). By default it will not use 3G when roaming. You can turn it on in settings. I have a Dutch Telfort sim and KPN took over Telfort. So i am on the KPN network now and my phone always thinks i am roaming.

Pay as you go or contract? Have you checked the APN entries as they differ on O2.

payasyougo and i changed the the user to payandgo.o2.co.uk also user to payandgo.
works fine in htc hero with 3g, not on samsung galaxy, just 2g

Flashed another Code(CODE_I9000XWJFF) and radio(MODEM_I9000XXJF8.tar) and 3g worked again.
then tried just flash the code (CODE_I9000XWJG5) and it still works. so i guess the radio (MODEM_I9000XXJG1) does not work for my samsung galaxy s properly
when i look now in the settings of 'about phone' i see
baseband version I9000XXJF8 and
Build Number ECLAIR.XWJG5
Does anyone think i will have a problem with that combination?

No 3G with Darky's Rom 10.1

I finished installing Darky's 10.1 Extreme Mod onto my Samsung Galaxy S the other day, and since then I have not had any connection to a 3G network.
I live in Australia and my phone carrier is Virgin Mobile running on the Optus Network. Before I flashed over from a Voodoo Lag Fixed stock 2.2, 3G worked fine.
I have checked in the wireless and networks setting to make sure the phone is set to "Use packet data" under mobile networks (Data roaming is turned off), but it makes no difference. I have also turned packet data off and on to make sure. Network Mode is set to GSM/WCDMA (auto mode). During setup for Darky's Rom, I left the Modem to defualt settings, JQ1 or something.
I'm not sure what I have broken but I'd love some help getting 3G back. It is very limiting to what a good smart phone can do.
Thanks

which model of I9000 u have? most likely is a modem problem i installed GB in my GT-I9000T and i had to go back to froyo cuz i didnt had 3G and low network reception...i recommend you to wait for more versions of GB come out if that is your case...

what about your APN settings?
Settings -> Wireless and Network -> Mobile Networks -> Access Point Names

So far as I can tell from the About Phone settings page, it is just a plain GT-I9000 with a Baseband of I9000XXJVO. Though I can't remember what it said before the flash.

There is nothing in the APN Settings. Should there be names?
More Info
I looked up the APN settings for Virgin Mobile Australia and entered them into the phone but when I saved the new APN it didn't appear in the list. Just gone.
I inserted the SIM Card into an unmodified Samsung Galaxy TAB in which I have used this SIM card in the past. Still can't get 3G on the TAB, and there was no settings in the APN section. Could be a problem with the SIM card?
I also used a feature on virgin mobiles website to send the APN settings to the phone but they return an error when trying to send me the settings.
virginmobile com au/internet-on-your-mobile-phone/the-vibe/get-set-up

Oddly enough if I just enter in the name of the network and no other details, it does save the APN correctly and works fine again. Sweet
Thanks though all.

Just as I suspected. Those are the 3G settings for your network. If you used Titanium Backup those settings are under [SMS/MMS/APN] Dialer Storage, just restore and reboot your phone and thats it.

AT&T Tab will no longer connect to AT&T data

I bought an AT&T Galaxy Tab. I confirmed when I received it, data worked, and then discontinued my service.
In the meantime I flashed to Overcome ROM, flashed to JPD to enable phone calls, brought it to Canada and used it there with a Canadian GSM provider, and now am trying to reconnect my AT&T service.
I activated my AT&T service about an hour ago, and everything seemed to be fine. I received the welcome to AT&T text message. However, it just won't connect to any data of any sort.
I've reflashed the modem to JPA, which I've seen people say works on AT&T, without any change.
I've installed the AT&T data usage widget, and it says "No Network Available or SIM could not be verified".
My APN settings by default were set with everything normal except for an empty password compared to what I found online. I tried setting a password and no effect.
Under Settings => About device => Status it shows Mobile network state as either Disconnected or Connecting.
Settings => Wireless and network => Mobile networks => Use packet data is unchecked, and whenever I try and change it, it will change to "Turning on..." and then after a few seconds it will change back to unchecked.
All of the Samsung related data connection toggles like on the pull-down windowshade or on the long press of power act like they're changing something instantly, but have no effect.
Anyone have any ideas on what's gone wrong here?

Someone stated earlier that their tab was kicked off of the network as well. I would try a series of restarts to see if the problem persists. If it does, try contacting at&t directly.
I Haz 3D!

I've restarted it about a million times in the past hour. I'll give contacting AT&T a try, hopefully it won't come up that I'm missing something from the stock ROM.

Called AT&T, they knew absolutely nothing, and couldn't help at all.
I suppose I'll try flashing a few more modems, including stock, and then I suppose I might have to reflash to completely stock if that doesn't fix it.

Try the sim card in another phone. They might not have apportioned it correctly.
Any modem will get you at least voice and EDGE, so don't worry about that now.
I have wap.cingular apn for a voice and data plan.

Hmm I'll see if I can dig something up. However, I'm a little unclear on what will happen because this is the $15 AT&T Tablet data plan, and at best I might be able to scrounge up a phone.
The sim card automatically entered wap.cingular apn on my tablet plan as well.

I was soo excited when I found this thread. This is clearly my situation exactly:
http://forum.xda-developers.com/archive/index.php/t-1083173.html
I was using the voice APN on a data plan. I deleted all the old APNs, created a new one that is just Broadband/Broadband for name/APN. Rebooted.
Hit connect, and.....it's still screwed up. Now it flickers back and forth on the status page between Connecting and Connected, and the status bar up top reflects the same - I'll see the H with arrows for a half second, and then it'll disappear again.
On the Mobile networks page, Use packet data now similarly flickers between checked on its own and unchecked and gray.

Okay, no idea why, but everything works now.
After Broadband failed to work, I tried changing it to APN Broadband. That didn't work either, so I changed it back to Broadband. Things then started semi-working in that the connection was still flickering on and off, but when it was on, data was actually being transferred.
I rebooted, and now it's fully working. Hope it stays that way. Seems to shift back and forth between H and 3G a lot considering I'm in the middle of a city with full bars not moving, but other than that, all seems well.

It would have been good to know about 1,000 word ago you only have the $15 broadband sim!
Apn is: ATT BROADBAND, and nothing else.

Hmm I have it set as Broadband, not ATT BROADBAND, and it's working for now so I ain't touch it.
Are people able to activate an AT&T Galaxy Tab on anything but the broadband sims?

Yes, I have voice and 3g data by ising a sim from my old android phone.

Android 5.1.1. Update Disables Mobile Data (D5803)

Hello,
I recently updated my Z3 compact (D5803) to android 5.1.1. on the T-Mobile network here in NYC. Ever since then, I frequently lose the ability to do anything data-based with the phone. No web browing, no chatting on whatsapp. I can still make phone calls and send/receive SMS, however. The data functionality returns when on WiFi, but goes away once I switch back to LTE. In order for me to get data on LTE, I have to manually download the internet settings for my provider to my phone (this is located under the Settings menu in android). Even then, it only lasts for several minutes before the data connection is lost. T-Mobile was unable to fix the problem, and changing the SIM card didn't resolve the issue.
Anyone else experience this?

Yes, many others have the same problem, see various posts in this thread: http://forum.xda-developers.com/z3-compact/general/discussion-5-1-1-stock-released-post-t3162309
Currently, the best workaround seems to be to disable and re-enable mobile data, or to go to airplane mode and back again. That solves the issue until you drop LTE connection the next time, then you will have to re-iterate.

Yes I am having the exact same problem since updating to 5.1.1. As the other reply says turning airplane mode off then on is the quickest way to get connectivity back (swipe down twice from the top for quick access). This is terribly frustrating though, it only lasts for a few minutes. I can't believe they pushed the update with this issue!

My phone had this issue after the over the air update. I reset the phone to factory, wiped all data. Two days on, now, and no more problems with this.

Same problem. I tried factory reset out of desperation, but it didn't work.
Love this phone, but very discouraged by this bug.
(I'm on t-mobile in Seattle, fwiw)

As posted in the other thread, there is now a fix/workaround:
From reddit user FishStik5: Going into the APN settings and changing the APN protocol to iPv4 only (it was iPv6 before) seems to fix the problem.
How to find the setting: Settings-> Wirelessa and Network / more -> Mobile networks -> APN -> T-mobile data -> APN protocol -> Set to IPv4.

Looks like this worked for me (T-mobile, San Francisco area). Thanks for posting this

i'm having the same problem and didn't work for my the ipv4. still loosing data, i have to reboot the phone

I have also problem with that (Orange, Poland). I sent my phone to official Sony service, they reload the software, but I still have that problem. Lte is working for a while and when my phone switches to wcdma (because it is not in a range of lte) it is not working either. However, when I change the preferred network from lte to wcdma it is working without any issues.

Same problem here although I'm on ipv4 [emoji34]
Sent from my Z3 Compact

I thınk you shouldnt buy operator phones. Buy ınternatıonal models next tıme

Mine isn't an operator model, I'm using Straight Talk and also have the issue. It made my phone useless....I almost never have data

This worked for me
This worked on my Doogee Valencia2 Y100Pro
Install and Open app "Hidden Android Settings" (by 0Alex)
Select choose and open "RadioInfo"
Move to Last option "TOGGLE DNS CHECK"
mine read "0.0.0.0 not allowed"
press the "TOGGLE DNS CHECK" so that it displays "0.0.0.0 Allowed"
That's it - my mobile data worked, I hope it works for yo

1. Change "APN Protocol" to IPv4
2. Change "APN Type" to: "default,supl" only
3. Change "APN" to "internet"
4. Save.
Best, Martin.

this is a bug on 5.1.1 sony need to fix it

Any news with this issue?

No problem here with LTE on the CM 12.1 Cyanogenmod flavor of 5.1.1 on T-mobile (that I've noticed at least). But I think CM 12.1 may handle the APN settings differently (mine is set to T-Mobile LTE ipV4) from the stock ROM or it could be something Sony messed up from the AOSP code. I'm NOT suggesting anyone try a CM ROM as a solution as there are lots of downsides to unlocking your phone and flashing any non-stock ROM. But the problem does seem to be specific to the Sony ROM and not 5.1.1 in general.

I also have this problem after the update to 5.1.1 in the Netherlands. The first problem was that the update changed some mobile data settings, so I downloaded the settings from my provider. Unfortunately those settings were also incorrect as I had to manually remove the APN's Proxy and Port (they were set, be needed to be 'not set'/empty). This improved the connection a bit, but it still looses the mobile data at certain places (where the coverage is good). Did a factory reset as the Sony helpdesk suggested. For a few days this seemed to help, but again the same issue came up. The suggested solution mentioned in this thread did not work as those settings are already applied.
I have a profider (Telfort) which uses another provider's network (KPN's). So after the update I also see a annoying R in the signal icon, where in the previous version it always showed H+, H, 3G.
Does anyone know if this is resolved in the new update?

After the last update and a new reconfiguracion on the APN now work correct for me.
