[Q] Text and call but no 3G - General Questions and Answers

I bought a Droid 3 (XT862) and unlocked then rooted/flashed it and put my AT&T sim in it. I can make/receive calls and texts, but I can't use 3G. I've tried messing with the APN settings with several different guides with no success. When I click "Operator Selection" I see "AT&T 3G (310-410)" and I have it selected, but still nothing. The 3G icon on the top of my screen has the up and down arrows taking turns flashing white.
And I'm not sure if this option does much, but "Select network" has "GSM Only", "UMTS Only" and "Automatic". Choosing GSM changes the 3G icon to a different style, but I've tried all 3 and nothing worked. And I've seen success stories of other people getting their Droid 3's to work with AT&T 3G so I know it can work, I'm just not sure what I'm doing wrong. Any help would be appreciated, this is my first smart phone and I'm having a rough start with it

Bump

maybe the 3G Function is disabled by the wireless carrier....? because i have the same problem last time , i called my wireless carrier to activate it , it worked

Weird APN / 3G issue

hi,
I'm on day 2 of trying to sort out my wife's new Captivate, so would appreciate any help at all. Phone is rooted, unlocked and has decent signal, but I cannot connect to 3g.
I'm on Optus network via TPG (Aussie network). I've tried many APN settings, and I'm at the point where I don't think this is the issue (yes, I know this is normally the issue).
I tried going into *#*#4696#*#* and doing WCDMA preferred, and WCDMA only, made sure AUS radio band was selected and did 'Enable data'.... also no help
I've also made sure data is enabled on the sim/account. If I insert the sim into another phone, it works with 3G. So it's something to do with the phone for sure.
Optus' 3g info says "2100MHz frequency band. Enabled with High Speed Packet Access technology (HSPA)". So WCDMA is the correct setting I think.
To be clear, I've never gotted the little 3G symbol at all (or an 'H' symbol that I've seen someone mention). I first tried emulating my own Vibrant's settings exactly, which didn't help.
Any ideas would be great.
thanks.
I'm completely out of options ... is there a chance this is an issue with bad contacts? I fixed my Vibrant's GPS by prying up one of the contacts...
All fixed. If anyone else has this trouble - flash back to stock, following this guide http://forum.xda-developers.com/showthread.php?t=884364
Note - I already had stock, so no idea what the hell was going on, but whatever.

[Q] Bars but Emergency Calls Only

First this only happens where I work in the basement where only certain providers (eg Verizon) have some signal in only part of the room. I did not get signal on AT&T or T-Mobile Pay as you Go down here.
I noticed especially after I flashed the new radio which gives me better service overall that I get phone signal down in the basement, but it is GPRS of Unknown Network and says emergency calls only. I get up to 3 bars. If I scan for available networks I get the name 31064.
Does anyone know what network that is or what is going on?
Anyone have any ideas? (I will take wild speculation as well)
i wouldn't be alarmed by it. I experience this at my office since I work in the basement...haha
It's possible your basement just won't read a signal like mine. install a window by your desk, maybe that'll help, but there shouldn't be anything wrong with your handset.
Sounds reasonable. I would agree with no problems with my handset. I do get better signal than my nokia e51, so maybe it's picking up a slight signal where the nokia could not.
From what I've noticed, my Nexus S acts this way whenever T-Mobile (my provider) does not have coverage wherever I am, but AT&T (not my provider) does. You can check this by going into "settings" -> "wireless & network settings" -> "mobile networks" -> "network operators" .....it will then search for & tell you what network has coverage where you are. Every time I've had bars & it says "emergency calls only" & I've checked the above, it's always been when I had coverage from AT&T but not T-Mobile.
Thus, it seems to me like an "enable roaming for emergency calls only" kinda thing.
Emergency calls only
ha ha....lol... i also have the same issue on my brand new i747M S3. im confused.
i try the all methods for resetting phone.
i noticed when im on long way, i dont know my handset is goning emergency calls only. but when im restsart phone its fine.
i do everything but not fixed it. firmware update, downgrade, rom change,and unroot. but not fixed, and also try factory reset the rom by falllowing the samsung secret code *#197328640# > UMTS>COMMON>NV REBUILD and restart and do again CDMA>COMMON>NEXTPAGE>REBUILD and restart., thhis is the code of full factory reset the rom and EFS. but not solve........
i change the hand set to international i9305 brandnew one. i used it 2 sady without issue.... day after morning when i wakeup, i see the massege,,,,emergency calls only,,im confused becouse this is a brandnew one...after i called the friend he also got the i9305. i asked about this issue. he said me he didnt face to this type of issue.. im confused he said me try sim change.. i do it... problem solved....:victory:
problem is the SIM card......i changed it to new one... and used i week no emergency calls issue... when im going to low signals areas.. its show no network and automaticallly change to the network....im very happy for fixing this problem.....:laugh::laugh::laugh:

[Q] Rogers APN Settings/CM7 Data Switching

I am having the data switching problem (stays in edge - wont switch to 3g/4g) on my Infuse when I install CM7. I have seen the 1 APN suggestion to fix this issues with AT&T but was wondering if there is a similar solution for Rogers.
as a work around I tried switching my preferred networks from WCDMA preferred to WCDMA only (i live in Toronto - so no issues having access to 3g/4g network at all times) but it reverts back to preferred, data switches back down and gets stuck in edge.
I am having the same issue. All I am getting is edge.
I have a nexus one though.
It only just started though. Probably within the 2 or 3 days..
Not sure what's changed
Same here.
It only runs on Edge. If I put my N1 on 3g, it works intermittently. Only when it wants to, and even though it shows it as being connected, it is not, as text messages come in hours later, and calls go straight to voicemail without showing anything on the phone .
I checked the APN settings, called Rogers, they confirmed all my settings were correct, but still, nothing.

[Q] Dual SIM phone roaming / not roaming question

Hi
I have a Zopo ZP950+ with Etotalk ROM, from China, it is a 5.7inch Phablet running stock JB, with Quad Core and DUAL SIM.
http://www.etotalk.com/zopo-zp950-16g_p3854.html
I am in UK, with UK SIM installed (T-Mobile), so at moment not roaming, but phone constantly tells me I am roaming.
I want to use the full 3G/HDSPA connectivity so do not want to disable data.. Under Settings/More/Mobile Networks, there are no options for roaming settings to change, though there is a "data connection - off" option, but I don't want to turn data off, and the roaming warnings are intrusive when sending texts or making calls.
If I can''t "fix" the fact that Roaming indicator is constantly on, even though phone is not roaming, can I hide the warnings every time I make a call or send a text?
Any 3rd party apps out there to help?
Thanks
While I wait for an answer, I will add this: I just tried a giffgaff SIM using O2 network, all is fine, seems to be a problem only with T-Mobile SIM, called T-Mobile they said I needed a replacement SIM card, but this SIM is fine in 2 other un locked (though not Dual SIM) handsets.

Hi there I have the same issue with my Star Note II N9599 and it too reverts to Roaming and I use Orange UKeven though its now part of EE Network UK but I did find out that the handset is actually Roaming! To check this go into Dial Pad and type *hash*hash3646633hash*hash* then goto Connectivity then down CDS Information the to Radio Information then to Phone 1 and you can see if the Sim in slot 1 is truely Roaming or Not?
I have yet to find a fix for this issue but did also stumble across my Associated Network Radio Bands as follows:
GSM MODE ( SIM TRAY 1 & 2 )
EGSM900 (selected)
DCS1800 (selected)
PCS1900 (selected)
GSM850 (selected)
UMTS MODE ( SIM TRAY 1 ONLY )
WCDMA-IMT-2000 (selected)
WCDMA-PCS-1900 (greyed out)
WCDMA-DCS-1800 (greyed out)
WCDMA-AWS-1700 (greyed out)
WCDMA-CLR-850 (selected)
WCDMA-800 (selected)
WCDMA-IMT-E-2600 (greyed out)
WCDMA-GSM-900 (greyed out)
WCDMA-1800 (greyed out)
WCDMA-1700 (greyed out)
Now at best guess I take it these settings are not correct for the U.K.
If this is so then which BANDS Do I Need and how do I go about changing the greyed out ones that I cannot select to be selected as a usable Radio Band?
I have looked as best I can on Google etc but Im all new to this and not entirely sure what to look for or how to do it if possible?
I have read other sites of users being able to change the Radio Bands for other types of Handsets so I know there must be a way?
I still have the issue where I can set my phone to Register on the Orange network and it connects and gives me 3G with Data but soon after the connection decides to reset to Roaming and drops Data unless I choose to select Data Roaming?

Carrier Settings and phone settiings

I've been using Three on my OPO for a couple of weeks now after I transferred from Giffgaff.
I am trying to avoid speaking to the support at three as they are notoriously bad. I've tried emailing them twice about settings after I searched everywhere for APN settings and advice. Eventually I managed to get a basic APN from a post on here along with instructions on how to change the preferred network type. However I am unsure I have covered everything and I have been having issues with the reception dropping out.
When it does drop out it keeps telling me there is no network (giffgaff) even though I think I've got it set up for 3, which is confusing me.
Other than the APN and selecting the network, is there a setting I've missed somewhere?
I'm still having issues with my phone dropping signal. I don't know if it is three or the phone. Is there any way to check this?
While sitting at my desk at work, I go from having H+ or LTE to having nothing with the "emergency calls only" notification.
Can anyone help?
