[Q] New phone -- no data. Suggestions? - Samsung Captivate Glide

OK, I took the plunge and got one. Checked a few things out, then went for the ICS update (official AT&T, at least for now) before I got too wrapped up in it. Seems I may have forgotten to check out that the data plan worked before the update -- I think I may have had Wi-Fi on all the time. Yeah, it was a dumb mistake.
Now I cannot get any data with any application when outside a Wi-Fi zone. Not even 2G, much less 3G. No connection and no indicator at the top. Phone is working on 3G just fine.
I have AT&T, though it's an old "Smartphone Unlimited" plan. It works just fine on my LG Expo (which is 3G). The phone is supposed to be unlocked (at least until I updated it, don't know if that affected it), but I have no non-AT&T SIM with which to try it. Have made no attempt to root it or load a custom ROM.
Are there some settings somewhere that I have to change to go through my old "wap.cingular" gateway (either rooted or not)? Should I try going to a custom ROM? Back to the original software (link, please, if that's the case)?
I'm going to see if a co-worker's T-Mobile SIM works with it (voice and/or data). But is there anything else I should try? Has AT&T finally caught up with me and my old, cheap, unlimited data plan and my SIM keeps me from connecting?

There should be no issue putting in a SIM from a working phone. If you go to System Settings->About Phone->Status, what is the network status? "Unavailable"? "Unprovisioned"?
Do you have signal, just no data, or do you have no signal?

I have full phone and text service, just no data (though, oddly, it says I have used 9.92KB of data). That occurs both at my home where I connect to my microcell and elsewhere. Of course, at home, I can also use WiFi for data.
"Mobile Network State" is "Disconnected". "Mobile Network Type" is "UTMS:3." If I turn the data network off and back on, it goes to "connecting" for a while, then back to "disconnected. I did find the location where it specifies the Access Point Names and it is set to "wap.cingular" just like my old phone. But unlike my old phone, the user name and password are "not set". These are uneditable fields.
I also went to the place it allows me to select my network operator and it offered me three different "AT&T" options. Two of the three gave me a message that my SIM does not allow connection to that network. When I try to switch to one of them, I see the data indicator go through Edge, 3G, and 4G, then off.
Only other odd thing I've noted is that the serial number is all zeros. The IMEI is correct, though; and I think that's what matters.
I'm becoming more and more convinced this is a problem with my SIM and the data plan it's tied to. It is from an old EDGE-only Windows Mobile 5 "smart phone" when that meant a device without a touch screen or QWERTY keyboard and a "PDA" was something that had either of those. The "Smart Phone" data plan was half that for a "PDA" but more than for a plain phone, and that's what I'm still paying. I've been buying phones outside of the AT&T system to hang on to that inexpensive, unlimited plan; but I may have reached the end of the line with it. I definitely need to try a SIM from another 4G capable phone,. both AT&T and T-Mobile, to see where I stand.

In the Access Point Names make sure that the profile you were talking about is selected. Or from that screen if you hit the menu button it should give you the option of entering your own APN. If you've had data working on another phone I would suggest duplicating the APN settings from it and try making a new profile.
It could be the SIM/plan you're currently on but honestly this sounds exactly like what happens when your APN settings aren't configured correctly.

Turn the phone off, remove the SIM, boot it with no SIM. Go into Access Point Names and remove all the entries. Turn it off, put the SIM back in, turn it back on. If it doesn't autocreate an entry in Access Point Names, or the autocreated entry still doesn't work, take it to an AT&T store and ask them for help.

There was no way to select the plan. So I made a duplicate of it, which did have a select button, selected it, and it now works great. Thanks so much for your help.

That would have ben last resort. They would have wanted to "upgrade" my data plan to something that cost more and isn't unlimited.
Your solution might have also worked, but the first one offered led me to a solution, so I never tried yours. I'll keep it in mind, though.

Success: carrier unlock, CID, tether on Optimus 7

I have successfully completed the following:
1. Carrier Unlocked a Telus branded LG E900h Optimums 7
2. Connected the phone to Fido
3. Use 3G on Fido
4. Fixed broken Call Display problem
5. Tethered E900h to laptop
6. Set up Wireless Zune sync
It took some effort time to figure it all out, so I thought I would share my experience to reduce frustration that any others may encounter. Most likely, many of these steps will be similar for other WP7 phones.
Unlocking the phone
Because my local phone unlock guy was closed the day I purchased the Optimus 7, I tried instantunlockcodes.com and purchased an unlock code for $10. I received 2 codes the next day, but neither
worked. I recommend not using this website, as tech support responses were next day, and they were never able to get the code working (after 3 days).
I took the phone to my local unlock guy, who unlocked it successfully. He charged me $65.
For anyone who is trying to unlock the phone, when you insert a foreign SIM, the Optimus 7 asks you for a PIN. This is where you enter the service provider unlock code. When I tried either of
the codes that instantunlockcodes.com gave to me, it said, "SIM ERROR". After looking around on the Internet, it seems that this is the message that comes up when it's the wrong code.
Getting Data on Fido
Telephone/voicemail automatically worked on Fido. To get Data to work (ie 3G) I had to change the APN setting.
Go to SETTINGS -> Cellular -> edit apn
"edit apn" is the button at the bottom of that screen. The settings should be:
APN: internet.fido.ca
User name: fido
Password: fido
Have Data connection ON and 3G connection ON.
Internet now worked for me, including browser and Outlook. Outlook connected to Exchange flawlessly.
Incidentally, the first time I set up my phone, I set up Windows Live immediately (startup wizard), and then Outlook Exchange. My appointments from Exchange were all in bright pink.
Because Windows Live was giving me a sync error, I did a factory reset, and set up Outlook first this time. Now, my Exchange appointments are in red. No idea how to change the color, but I
prefer red. In both cases, the Windows Live account's appointments are in Blue.
Call Display and MMS
Call Display and MMS did not work. Frankly, I don't care about MMS (there is another thread on how to fix this), but Call Display is quite important.
Specifically, Call Display worked when land lines called me, but did not call when most cell phones called me. They would read, Unknown.
The solution to this was through Fido: I had to call them and change my Call Display from "Call Display with Name Display" to "Call Display WITHOUT Name Display". Evidently, this problem has
manifested in other unlocked phones, such as some Blackberries as well.
A point of interest: when I put in the original Telus SIM, the call display also did not work properly. They must have given me Call Display with Name Display as well.
Tethering and Wireless Sync
Tethering is a really handy thing for me. I use it infrequently, but it's really invaluable when I need it.
I've modified the solution that's been posted around, to be specific to Fido, but to clarify a couple of the screens, as well:
1. If you haven't already, install Zune first. While tethering is enabled, Wired Sync on Zune won't work. But Zune has wireless synch, which is way cool anyhow.
2. Set up Wireless Sync on Zune. I won't go into all the details, but basically, make sure that the phone is connected to the WiFi network, that your PC has access to the same network (it can
be hardwired, as long as it has access to the same IP subnet). If you have a guest/work router, make sure that both your phone and PC are on the same network. With your phone plugged in, run
the Wireless Sync wizard on Zune. It's painless.
3. Unplug your phone.
4. Press Phone, and dial ##634#, then press the Call button. This makes visible a hidden app called "MFG". Go to the list of all your apps, and you'll see a new icon with a hammer, wrench and
screwdriver lablelled MFG. Open it.
5. You'll be asked for a password. Enter 277634#*# -- you'll need to enter this password every time you want to go into MFG, which is a good thing, because I think you can seriously mess up
your phone if you play around in there.
5. Go to Engineer -> Port Setting
6. Select the QC COMPOSITE and validate. The phone will automatically reboot.
7. VERY IMPORTANT STEP: This is totally counter-intuitive, but you must go to SETTINGS -> Cellular and turn OFF Data Connection.
Note that once you're done tethering, you need to turn it back ON in order to use Internet on the phone.
8. Connect the phone with a USB cable.
9. Windows will automatically detect the phone, and if you're using Windows 7, will prompt you with a popup with the download link for the LG driver. It says LG CDMA driver, but it works. The
full file name is LGUSBModemDriver_Eng_WHQL_Ver_4.9.4_All.exe
10. Once the drivers are installed, click start, and type "Modem", click Phone and Modem.
11. Click Modems, double-click LGE CDMA USB MODEM, click the Advanced tab.
12. Under Extra Initialization Commands, enter:
+CGDCONT=1,"IP","internet.fido.ca"
Replace internet.fido.ca with a different provider APN, if you're not with Fido, obviously.
13. Close the Modems screen, click Start, type "Dial" and click Set up a Dial-up Connection.
14. Enter your home area code because Windows forces you to, and go to the next screen. Then enter as the dialing number:
*99#
Leave the login/password blank. Click connect -- and PRESTO! Tethered Optimus 7.
* IMPORTANT *
Once you're finished tethering, you need to turn Data Connection back on. For some reason, when Data Connection is on, tethering doesn't work. Fortunately, it's a pretty simple toggle to
switch.
I hope that this is helpful!
Thanks for the great info! Just picked up a Telus HTC Surround and was concerned about the CID issue. I'll give this a shot.
You guys paid full pop then for the telus phone?
I'm suprised it costs $65 to get it unlocked...there has to be a way to do this for free...the cheap bugger in me doesn't like to pay for such things!
Yep, paid full at Best Buy. My Samsung Galaxy S just broke last night and I need a smartphone like there's no tomorrow, heh heh. Decided to give a WP7 phone a chance this time.
Yes, I paid $499 CAD + Tax. But, I'm ahead, because I bought an iPhone 4 on renew for $250 or so and sold it BNIB for $960 a few days after release
I have an issue with Text message timing - they are coming through with times that are not the same as my time zone.
UnlockThatPhone.com only 14.99$ and after 18h they send me 2 codes and now I'm so happy
did it work?

[Q] Preferred Network Type won't stick?

I'm trying to set "Preferred Network Type" to "GSM auto (PRL)" on my Galaxy Nexus as 3G coverage is really poor at work.
I get into the menu with *#*#4636#*#*, select "Phone information", choose the option in the drop down box, but if I press back and then enter the information menu again, it's back on "GSM/WCDMA auto" (the default)
Does anyone know a way to make this setting stick? There doesn't appear to be a save or update button anywhere.
Bumping this as it got little attention before.

Doesn't stick on the nexus s either. I've simply come to the conclusion that samsung doesn't implement these things properly. Never have I had as many radio/gps issues on devices made by any other manufacturer as I have on samsung devices.
Just posting to say that the settings does stick on mine (I know this since I had to use it to disabled 2G back when the volume bug was rampant) so it must be a problem with certain set ups. No idea how to fix it though. Try a factory reset I guess?
Sent from my Galaxy Nexus using XDA App
Interesting. I guess I'm going to have to go for a factory reset when I root it so will give it a try again afterwards.
Same thing here, any updates on this issue? Thank you.
The factory reset made no difference. In the end I've gone with rooting my phone and installing Toggle2G, which switches the phone to 2G when on wifi or when the screen's been off for a long time. This basically has the effect I wanted and saves a *lot* of battery power into the bargain.
Instead of hitting back after setting just hit home button it sticks if I do that
-----------
iphones are the creation of people with nowhere left to turn
I thought that but I can't really be certain that it's ever made the right option stick.
Yea just go back in and it will stay where you left it....hit home to get out
-----------
iphones are the creation of people with nowhere left to turn
Thought I'd update this and point out that the LG Nexus 4 seems to have the same problem - putting GSM auto (PRL) on doesn't actually disconnect the HSDPA service. Of course, it's possible that the networks just aren't very good at updating their own PRLs as I understand it's something that has to be engineered by them. I just want a setting where if the 3G signal is rubbish and the 2G is good, it'll stop trying to use the crap 3G and use the good 2G instead and save my battery. Might be requesting something impossible, though.
Don't press back, select it and just press home, don't swipe it off the recent app list too, that way it will stick.
This appears to work much better on the Nexus 4 (which I now have) than it did on the Galaxy Nexus

I just moved a locked Samsung A10e from AT&T to Mint (T-Mobile).
Here's what I learned:
I should have first unlocked the phone while still active on AT&T. This way I could still perform actions on the phone.
Then test the phone with the new sim before transferring the number. This way I can still use the phone.
I would have discovered the unlock still had a problem.
Here's what I learned. My Samsung was Unlocked by AT&T through their online request (https://www.att.com/deviceunlock/)
I inserted the new sim but it wasn't connecting to Mint. I found that if I changed the preferred network to "GSM/WCDMA preferred," (*#*#4636#*#*)
this resulted in a connection to Mint. But if I rebooted, it would revert back.
Then I found code *#2263#. I changed the setting here and the phone stayed on Mint after reboot. I changed the Band Selection from Automatic to WCDMA/GSM auto connect.
If you want to re-enter your unlock code, try this code #7465625*638*#.
The last thing would be to transfer the number according to AT&T process or dial *PORT.

One X on AT&T H to 3G to H... rinse and repeat!

Guys,
Unlocked and rooted One X on AT&T and my pegged out signal keeps changing from H to 3G over and over and over.... you get the picture. Never stays on one very long before changing and will disrupt data services for a brief moment while it does.
Is anyone else seeing this behavior and if so, any fix to resolve?

Yea I notice it. I believe it's part of the way it saves power but idk if thats true because on my Galaxy Nexus, it would almost always stay on "H".
Mine doesn't really switch out of "H" though when actually loading something, just takes a bit to go from "3G" to "H". I've maybe experienced it once or twice when actually loading something where it would switch out of "H" to "3G" while loading something on XDA or a website. But it's usually when connection is weak.
I'm having the same issue.
if it keeps happening, then complain to ATT and ask for credit on your data plan because it doesn't work the way it should.
From what I read, AT&T phones show only h, even though in the background they switch back and forth.
But when you use international phones on the network, it will show the switching around. I'm not sure if that's related to your issue, but over here on rogers, my phone switches between 3g and h constantly, even when I'm at one location.. The thing is that I don't get long disruptions though, if any at all.
I'm on att and don't experience this. My icon switches frequently but I don't see any interruption in service.

Thanks all, just wanted to make sure that I was the only one experiencing. I will probably go into the AT&T store and see if their One XL display units is doing the same thing while I have mine with me.
Could be that "international" issue type of thing... who knows.
Yes, mine does this too. Im on straight talk which uses at&t and it frequently keeps switching back and forth.

Moving from 2/3G to HSPA+ is by design and called fast dormancy. Here's more than you could ever possibly want to know about it.
http://www.slideshare.net/zahidtg/gsma-fast-dormancy-best-practices
It saves battery life and when working properly it's undetectable. That is when FD is active on a device and the network it's using supports it. (AT&T does). If OP's dropping signal something's wrong. I'd check...
- The APN's you use on AT&T must match the plan that's provisioned in your account settings. If you're on a 3G plan (grandfathered unlimited, MediaNet, data for non-Smartphones) use the 3G (Cingular) settings. If you're on a 4G (non-LTE) plan use the 4G (HSPA+) APN. Wrong APN means funky data even if it seems fine sometimes.
- Older SIMs or SIMs from iPhone's in non-Apple devices have caused problems. As has bad surgery in the move to micro. Pop in to an AT&T store and get a new micro SIM matched to the provisioning of your account.
- Bad phone h/w. In not the above it could be the device.
I've just been across the country on the AT&T network and my phone has performed better than my i9100 in picking up and maintaining a signal (I'm on a 3G plan). It's been impressive actually especially in moving from HSPA to Wi-Fi and back. So with the right settings the phone itself should be fine.

Just tried that and it's not working for me. Doubled checked, everything is exactly as he said. I just don't have the option to switch from what it currently is (MediaNet). There's no radio button for the other two. Even after deleting the original (only leaving the two I just made) and restarting, I have no connection to the network.

After you set up the new APN's try deleting the old one. You can always get it back by selecting "restore to default."

I had an unactivated micro SIM that I had my corporate account rep activate so my situation's different than yours; the SIM is tied exactly to the settings in my account. I popped it in, it picked up the MediaNet settings, and all was good.
My phone has a single APN so I can't see the way the settings look when there are multiples. The last setting in the active APN is "APN enable/disable" which is greyed out on my because there's no other choice. Did you try disabling it after you got the new APN's entered? Maybe if you do it'll allow you to select the new APN's you created.

My "APN enable/disable" is greyed out as well. I tried the new APNs in the other thread and couldn't get a internet connection. The only successful APN with the One X was the medianet. Other than that, I'll settle for the medianet but only wanted to change it to get better speeds in my area since this phone is capable of receiving up to 21mbps.

The highest I've seen on either an international phone or an AT&T 21MB-capable phone is 8MBish down. That's in TX where there's lots of bandwidth shared by not a lot of people. In markets like LAX, NYC, and SFO you're lucky to break 5MB because of the congestion. I've seen 2MB and under in Manhatten. HSPA+ speeds on AT&T are very much YMMV.

Not Registered to Network?

Today I lost my ability to make phone calls or do anything with my phone away from WIFI.
If I tried to make a phone call, I'd get a "Not Registered to Network" error message.
I can still do WIFI calling but nothing else away from WIFI connection.
I then went into network settings and chose "manual" for network operators. I was able to restore texting and calling. But I have no data. The options that I see from the scan after choosing "choose network operators manually" are 3-5 choices and they all read "Home". Some of these options give me error messages and others gives "Registered to network" - which then lets me call and text message.
So far I have tried rebooting. Taking out the sim tray and placing the sim card back in. I have tried resetting network settings. I have tried resetting APN to default.
Anyone know of a fix for this Samsung message occurring on the A70?
I am trying to do what I can to avoid resetting to factory defaults.
Thanks.
Others things I have tried:
Placing sim card in the other tray.
Making sure my sim card works in another phone. (It does.)
I fixed the issue.
Restoring APN to defaults or resetting APN, does NOT work, apparently.
I had to manually create and save an APN and enter the appropriate data, as instructed by my carrier's website.
The key data entry was probably adding a website (fake example: "t-mobile.com") to the "APN" entry, which was blank in the default APN that my Samsung was using. I wonder what happened there.

Last week an earthquake has occured at Istanbul (5.8) and all the gsm carriers stopped working for hours at whole country. That was interesting. And when you tried to call someone, phone were showing a dialog which was shown to you. And also as you said, peole had to use wifi to call someone via WhatsApp etc.
So, I think the problem you lived may be your gsm carrier's issue and probably they fixed it while you were trying to fix it yourself.

No. The notion of an outage of service occurred to me but ultimately the fact was my sim card worked just fine in my other phone.
The problem and fix had everything to do with the APN file. I'm just wondering why that APN would change all of sudden.
What I've read about Samsung phones is that this "Not registered to network" is a common problem.
I hope this thread will be useful to someone in the future.

LG G8 Amazon edition on Sprint, can't make/receive phone calls/texts, but HAVE Data

Got the LG G8 unlocked Amazon Alexa edition last August (2019). I use it with Sprint. I love the phone and it worked great, until a month ago.
All of a sudden, I can't make or receive phone calls or text messages, but I DO still connect to the Sprint cell service (I have bars) and I DO have working 4G LTE Data. Literally, one day it worked and the next day it didn't. I hadn't powered cycled the phone or anything between it worked and when it suddenly didn't. It just stopped working.
When I try to call out, the dialer gives me an "Out of service area" message, even though I'm within my service area. When someone tries to call me, it goes straight to voice mail as if my phone is turned off, except that my phone is turned on. When I try to send a text, it sits at "sending" indefinitely and never sends. When someone sends me a text, I simply never receive it.
Sprint, I do firmly believe, has done everything they can to troubleshoot it and proven it's not a network issue. Several different kinds of resets, including a factory reset. I was able to reactivate an older LG V20 on my account and it works just fine.
The phone is still under warranty with LG, and I was able to send it in for repair at no cost, but they did not find anything wrong with the hardware. They did do a software update of some sort, but that did not resolve the issue.
So now I'm essentially stuck between both Sprint and LG saying it's the other's issue. First unlocked phone I've ever bought and it bites me in the butt.
Any other ideas for troubleshooting either on the phone itself (beyond all the standard stuff which I've already done; I mean, if a Factory Reset doesn't help...), or with Sprint?
Thank you!
I had the same problem with Amazon variant. I used an app called Hidden Settings Muiu and went to "Phone Info" then switch the Preferred Network Type to LTE only leave it on there until it says LTE on data and no network on Voice then switch to LTE/CDMA and it get 1xRTT. Ive tried tweaking settings and everythingelse but no luck that seems to be 100% effective but anytime you **** with your network or restart you'll have to do that.
Edit: Do Global(PRL) then LTE only then to LTE/CDMA. Otherwise itll stay on EvDo for data not LTE.

Did try that and gives me data but no cell service. Thank you though
Had same problem from a newbie...
I used ##873283# with dial key pad. It took a few times but finally worked. As soon as you power off or restart your phone, your back to where you started.
I bought mine from bestbuy 1 1/2 yrs ago. They are having lg send me a new one...
Lg v8 thinq This is the model I had* LM-G820QM.
