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.

Does 2G work on Telus with Milestone?

I'm currently using CM 6.1.2 on my Milestone.
If I switch to 2G mode in the mobile network settings, I have no connection.
If I use the Toggle 2G app, it doesn't seem to really do anything. If I set 2G to use one of the options that don't disconnect me (WCDMA, CDMA or GSM 2g/3g) it still shows 3G in the status bar so I'm not sure what the point is in using the Toggle 2G app.

Wondering the same thing myself...
Does anyone knows the answer?

I am not certain about this (i use rogers), but i believe that telus has no 2G (edge) network. They built a 3G only network just in time for the olympics to replace their cdma network:
So the toggler probably cant find a valid connection and retries 3G.
Manual mode cant find a network at all.
On rogers, i can fallback to 2g. This is normal according to what i think i know.

thanks for the info.
That's what I thought so have given up on the idea of getting 2g to work
I guess when it comes to 3g and saving battery life, juice defender will have to do as it can turn off data when the screen is off but still have the phone working.

Well, I think I made some progress with this.
On my phone, I was also loosing the connection when switching from 3G to 2G but it's working now. I can get calls, it's only the data aver 2G that doesn't work now.
I have the Cronos rom on my phone, I can tell you what I did if you're interested.

Yes please do.
If it works on cm6 then at least I can also save juice by not using juice defender... oh the irony... lol
edit: hey look at all them Canadian flags, eh?!

Took me a lot of time to find the right switches combination.
Anyway, I have Toggle 2G auto managing the 2G/3G and for the bottom 2 options:
2G network: WCDMA preferred (3G/2G)
3G network: GSM auto (PRL)(2G/3G)
If I check under Setting/About/Phone/Status, I see written mobile network type UMTS.

Hmm... I had those 2 settings reversed when using toggly2g
I will try that.
Right now, my mobile network type shows up as HSPA.
Your post prompted me to find the difference and came up with these 2 useful pages just before my head exploded.

Not sure but I don't think so. You can turn off the data but have the phone connected to the 3G network, right?
I think you could get data over 2G but it's just very slow, right?
With Telus I don't think they allow data over 2G.
zeppelinrox, I wonder why yours shows like this, what do you have active under those settings?
What ROMs are you guys using?

When I'm on 2G it shows as UMTS
With 3G (mobile data enabled) I see it alternating from 3G/UMTS to H/HSPA.

I'm on CM6.
My phone always shows HSPA except if I set it to use 2G then it shows GPRS - which is when I have no data and no phone signal.
I did use the Telus baseband file in AOR though... I wonder how it will behave if I use the Canada baseband....
Also, here's a neat trick....
dial *#*#4636#*#*
A Testing App will show up....
Select Phone Information and then goto the bottom.
You can set your preferred Network type.
Ok so that listbox shows all the different options.
The only options that will save are:
GSM only (2g - I get nothing - shows as GPRS)
WCDMA only (3g - shows as HSPA)
GSM auto (PRL) - (3g - shows as HSPA as well)
All the other options either are not selectable or just revert back to GSM auto (as is the case with WCDMA preferred)
I just did a few speed tests and I seem to get faster speeds with GSM auto than I do with WCDMA only
Gonna try that Canada baseband now....
Edit: Same thing. Except the speed test is slower for both WCDMA and GSM autio so best off using the Telus baseband.

The dial trick doesn't work. I dial the sequence as a phone number, right?
It disappears then nothing changes.

ah.. yeah sometimes it takes 2 or 3 tries...
do you use adw launcher?
If so, you can actually create a shortcut for it... I figured it out today.
1 Press and hold on homescreen and select Custom shortcut
2 Press "Pick your activity"
3 Select the second item on the list ie. Activities (with the ADW icon)
4 Wait for all stuff to load, scroll down to Settings, and press the arrow next to it to see the long list of activites that Settings.apk can do.
5 Scroll down near the end of the list, you will see Testing(.TestingSettings)
6. Select that and press OK on the next window.
I also made one for Battery History, which is actually part of the Testing app but is usually only accessible through Spare Parts.

I still can't get the trick to work... doesn't do anything on my phone
Right now I'm on the 2501 rom (latest 2.2.1 from Motorola) and I can say it's the best I've tested so far!
Outstanding battery life!

I found another way to run Testing App.
With Google gesture search you can set it to launch Settings actions
Let it scan and then write "testing" on the screen
Edit: oh crap I mistyped the code.
Its *#*#4636#*#*
I had 4536 before so I fixed it

Well, after doing some more tests and trying different apps (2G/3G switchers) I can say those apps work only if your cell phone company has both 2G/3G network.
In Montreal, only Rogers has both.
Easy to test (btw: I'm using the FroyoMOD rom): go in "Settings" -> "Wireless & Networks" -> "Mobile Network Settings" and check "Use only 2G networks".
See if your cell phone company is listed when you do a search under "Network Operators". If it's not, don't bother using a 2G/3G switcher.
When doing this, in Montreal I see only Rogers listed. If I uncheck "Use only 2G networks" I see all 3 of them: Bell, Telus and Rogers.
Hope this helps!

[Q] Unlocked but no mobile data

So I've recently purchased an unlocked Sprint HTC One. I am able to use my current tmobile sim and am able to send/receive calls and texts. The only problem however, is that when I try to turn on the mobile data, it won't connect and just says "disconnected." Can anyone shed some light as how I can approach and resolve this problem?

Does the phone's GSM radio use the same frequencies for data that T-Mobile uses?

I know that the Sprint HTC ONE doesn't have the 1700 Mhz band, only the 1900Mhz. I've read that even if I'm not in an area that is refarmed to the 1900Mhz band, I'll still be getting edge. I live in the Los Angeles area so I'm more than likely to be in an refarmed area.

Connect to wifi and update PRL and profile.
If nothing, try forcing hands-free activation. In the dialer: ##72786#

You probably need to setup T-Mobile's APN to get the data to work. Not sure how to do that on the One though.
BTW, expect GPRS/EDGE data to be quite slow, even if you do get it working.

I haven't had to do anything special with APNs for Tmo data. I get Edge in the non-1900mhz areas and HSPA+ in the 1900mhz areas.
In the Mobile Settings page... I have all roaming guard options unchecked. GSM data checked. Set to GSM/UMTS only. Search for networks.. click on Tmo... and away I go..

I've never touched anything related to APN. just select TMO after the network scan and use. Id assume the APN stuff is auto-populated by htc/sprint settings built in.

I tried resetting the APN to default and reconnecting to the TMO network, however, I still can't get any mobile data. I'm hesitant to seek TMO for help as often times, they'll just reply saying that it's a Sprint model, so not everything will work.

So I got the mobile data to work, however, only when I'm out and in certain areas. At home, it still says "disconnected" however, if I'm out in some areas, I'm able to connect to the 1900MHz band. Is there a reason for this happening? Mind that I was only probably a mile away from my house.

Was there a solution to this ? This is my problem also in los Angeles

[Q] [C6603] need help with lte setting(t-mobile), thank you

Ok, so at first i cannot even use the mobile data, and then i change my apn setting
Name:T-mobile
APN:epc/fast.tmobile/t-mobile.com<-i have both
MMSC:mms.msg.eng.t-mobile.com/mms/wapenc
which i tried both and found that it only activated edge network, not even 3G network
what is going on with my phone? or maybe it is because i lived on a mountain and there is no 3g/lte signals here?
thank you

the apn should be fast.t-mobile.com not epc/fast.tmobile/t-mobile.com

Wifi Hotspot - Tethering

I went ahead and enabled data and tethering for my Ting sim.
Ting's FAQs suggest that tethering cannot be used with LTE data, but I had no problem. Ting with LTE connection showed the same speed on the R1 HD and the wifi connected device, at the time, about 20 Mbps up and down.

Is Data roaming enabled?
Is the modified APN selected?
Are both "default" and "dun" checked under APN type in that APN?
Until "dun" was checked, my sim behaved the same way, connected but no internet.

All my fp sims are downgraded to free 200mb plan with no services. I have two types of sim, data only and voice/data. The voice/data sim gets a number assigned before shipment.
The one in my R1 HD is voice/data, but I am not using fp voip phone and have run the fp messaging app only to check activation; it's not running now.
I'll swap to a data only sim this evening and see if the hotspot continues to work.

Swapped in a data only sim, hotspot still works fine.
I assume the icon on top bar has an R to indicate it's registered and same icon in the dropdown menu has the R and is labelled FreedomPop.
Also, I assume the sim is providing data locally. Speedtest should show a ping of about 300ms.
Running out of ideas...Settings/More/Cellular networks shows Preferred network type 3G/4G. When I click on Network operators, it searches for about a minute and then shows FreedomPop 3G twice...I'm guessing one of those is ATT and the other is T-Mobile. Haven't noticed any difference if I select one or the other.

Using freedompop sim on sim2 with data choosing sim2. APN/Data Roam enabled. Hotspot can be connected, but no internet going through. I might think this is a bug of the stock ROM.

The fix described here, adding dun to the APN type, has worked for me with several fp sims, both the data only and talk/data variety:

Apparently it worked for "Blu R1 HD User" as well. Expect we all have the stock rom.
My guess is that the problem is differences with the account setup at freedompop. They may be trying to disable it so they can charge for the service but have not made changes to all accounts.

The "dun" trick was tested NOT to work on my R1 HD. Same, connected, but no internet. I am wondering is this a BLU issue or FP issue. In other words,
1) has anyone successfully tethered using other carrier's sim cards in BLU while not with FP? Then that's a FP issue..
2) has anyone successfully tethered FP's sim card on other GSM unlocked phones, while not in BLU? Then that's a BLU issue..
I am not a GSM player (I play with CDMA phones a lot), can someone do above experiments and show your results? Thanks.

No problem tethering from a BLU Studio 5.0 LTE (Android 4.3) with fp sim.
HTC M8 (Android 6.0) has the "connects but no internet" problem with fp sim.
My phone is set up as shown here:

I can tether from either data source. HSPA+ speeds from fp sim, LTE speeds from Ting (T-mobile).

It would be great if someone with a rooted R1HD could find something like this:

I believe that Android 4 phones may not give carriers the ability to identify(and block)
tethered traffic. An obsolete GSM phone with a fp sim might make a cheap hotspot.

That's not it. Hotspot still works without security.
But I think I've figured it out.
In brief, I believe that adding dun to the APN type works only if you are connected to T-Mobile.
Freedompop sims can use either T-Mobile or ATT HSPA+ data. If you connect to T-Mobile, tethering works, if ATT it doesn't. I am in a location that gets both, but T-Mobile is stronger and I think it normally gets selected. When I click on Network operators, it searches for about a minute and then displays this:
I think the two "FreedomPop 4G" items are ATT and T-mobile, When I click on either one, it says "Registering on Freedompop 4G". These don't seem to appear in the same order each time, but when I choose at random, about half the time I get no internet when I reconnect the wifi device. When I tell it to "choose automatically" I always have internet, I think because it chooses the stronger T-mobile signal.
Googling: dun apn tether, shows that this was a solution to a T-mobile broken tethering problem.

There must be a way to force the device to connect to a particular network.
Does anyone know how?

I did some searching for APN settings for ATT back when HSPA+ was all the rage.
Came up with this for APN Type: default,supl,dun,hipri
I still can't tell whether I'm connected to ATT or T-Mobile (there must be a way, but I don't know it).
But I've been trying manual selection as before, which often failed to tether internet. Now it always seems to work.
Would someone who has been unable to tether with a Freedompop sim please try this APN setting.
