Wizard airplane mode on and off on its own with gophone sim

Sorry about this post but I looked everywhere. Im usualy an android guy but a friend gave me an cingular branded wizard the other day.
Now I know these phones are old.... first sign is the fact it still says singular lol.
My problem is, I have a couple old Att 3g go phone sim cards from my iphone that still have money on them and I would like to use it up. Now I know the Wizard is unlocked because My tmobile sim card works fine as soon as it boots, But I use that in my much upgraded G1.
When I put the Att gophone sims into the wizard, it shows as cingular, but every min or so, airplane mode switches on just long enought o cancel the network then it tries to find it again. over and over for both sims, neither of which are locked to any phone.
Now if it just didnt get a signal Id be fine.
But, I go into the network settings and see it switching airplane mode on and off loosing the 3-5 bar signal I get.
I guess what I want to know is do go phone sims work on wizards? did I do something wrong? is there anyway to permanently disable airplane mode as I will never use it?

[Q] Limited Service, Emergency Calls Only - No Signal

Hello all!
I've made some searches, but I could not find a resolution to my problem (and very few people seem to have this problem!).
Sometimes, in Android only, my phone will drop signal to zero. This most often happens when coming out of sleep, but it happens sometimes when I'm just holding it, too.
I'm thinking that it most often happens when it switches from HSDPA to EDGE or from EDGE to HSDPA or when it gets a particularly strong cell signal (rarely, though; I'm on T-Mobile USA).
I've read about PPP drops, but I don't think this is the same--in my case, the signal just goes to nothing. It's like I'm in a basement. No voice calls, no SMSes.
Once, I was able to get to the choose-a-network-screen; there, I chose T-Mobile, and it told me that the SIM was not the correct one for the network. Other times, I've gotten to that screen and T-Mobile could be chosen. Another time, it'll give me an "error when searching for networks."
Does anyone have any suggestions for this?
Thanks!
Edit: I thought I'd clarify; this happens across every Android build. I've tried 15 and 14 radios. The Europeans seem to have this too: http://forum.xda-developers.com/showthread.php?t=796713 ... Is there a solution for this? Thanks!

Have you tried using secret setting to get onto phone options and change cdma preferred to gsm auto prl. I used to have this problem too. Dial *#*# 4636#*#* to get to those settings or download free app "secret phone setting" from market. Hope this helps.

Hi,
Thanks for your input! Unfortunately, I think this disables 3G in general as well... do you know of a workaround that still lets me keep 3G?
Thanks!
Edit: My apologies; other solutions that have mentioned GSM seem to think that it keeps it at 2G. Looks like this might work, even for 3G! I'll keep y'all updated. Thanks again!

How does this work for you?
I have ths same problem, and I can't get the 3G to work regardless of all the setting.
Also tried the secret setting.
Still limited service
Using tmobile usa, t-zones, rafdroid 3.0
Was okay and slightly on and off intermittently until yesterday, totally lost connection.
Please help

Hi,
Did anyone here able to resolve the problem? I have exactly the same problem. I am on T-Mobile US (HTC sensation 4G), my phone has stopped picking up any signal. It always shows "limited service/no signal". T-Mobile customer center is saying that there is no issue of signal strength in my area. In the phone, under wireless and netwoks setting, I am unable to check "mobile network" option too. I did factory reset too but thats also not working. I have also contacted T-Mobile and tried using the settings they provided for APNs but that did not work too?
I tried searching at various places but no one seems to have faced this issue. Any help on this issue would be appreciated.
Thanks in advance.

Limited Service, Emergency Calls Only - No Signal
Our HTC HD2 is showing Limited Service, Emergency calls only.
We are running Android From NAND by aMAGLDR V1. 11 build DEC 31 2010 Cotulla 2010. The Limited Service, Emergency calls only began today
at 9am and the issue hasn't been resolved.
Is there any step by step suggestions?
Changed secret settings WCDMA to
GSM auto (PRL) with no resolution.
Would a hard reboot resolve this issue? How is a step by step hard reboot performed on the HTC HD2?
Thanks in advance.....

First step tho I'm sure you tried this already would be to reseat the sim card, followed by testing the sim in another phone, then another sim in the hd2.

i you can put another t-mob sim in phone,or if unlocked,any sim in and look in android settings,phone info,that the phone number is changing when sim changed,have had problem with 3uk sims and some other sims that the phone does not appear to notice that the sim/ number has changed ,some services will work,others wont..
ang get same prob hunting for providers failing.
perhaps android has a bug.
could be faulty antenna connector on phone.
could be worn/damaged sim or sim holder in phone.
could be t-mobs problem their end.

When T-Mobile opens we will install new SIM.
The HTC HD2 is new so have no idea if the issue is
any of the above you listed. T-Mobile has the best service plans
but the worst customer service.
We require a true unlimited plan because 90% of our calls are
to landlines.
Thanks for your response.

Required sim card upgrade!
7 NOV 2011 UPDATE ON LIMITED SERVICE, EMERGENCY CALLS ONLY!
Visited a T-MOBILE store and the SIM card was 2G and they upgraded
the SIM card. It resolved the issue.
We thank everyone who contributed to this issue.
T-MOBILE representative stated the HTC HD2 could never achieve
4G. Attempted to upgrade us to a Galaxy 4GS II. We will never
pay retail for a phone.

Network Mode
I had this issue as well on my HTC Sensation. What worked for me was to set Network Mode to "GSM Only" (Settings/Wireless & Networks/Mobile Networks/Network Mode).
It was weird, when I had 4 bars I could make/receive calls, but when reception was 2-3 bars it wouldn't. It has been less than 24 hrs so not completely sure the problem has gone away but worth a shot.
Bonne chance.

My solution
Hey Guys!
I had the same problem after upgrading my Moto Milestone 2 to 2.3.6 Vivo ROM. When I went to class at university I had "Emergency calls only" - not "limited service" or "no service". So I had receiption... Also I could select any other provider but not my own (T-Mobile Hungary). The same thing happened when I was at home, in the house. The strange thing was that I didn't have any problem at any other place. Also, when I locked my screen and didn't use the phone, I had bars and could receive calls&sms, but after waking up the phone, the bars went down to 0 and got the "Emergency calls only" message.
I Googled a bit and found an answer which was worth a try before asking for a new SIM card from my provider ('cause that was the only solution I found in every other forum).
So the things to do are:
dial *#*#4636#*#*
go to Phone information
Scroll down to "Set preferred network type"
Select "GSM auto (PRL)"
My default was "GSM only" and after setting to auto I had full bars.
One thing to note: I don't use 2G or 3G or 4G or any other G. I just use WiFi for browsing and other than that, GSM to receive calls and send SMS. If you need 3G I think you need to change to some other settings. But you should give it a try.
Cheers!

Emergency calls only; When Android pie sleeps
I notice several times since I loaded Android Pie on my Oneplus One that the system, to save battery, is shutting down apps, even system apps. One of these is the phone service causing my phone to read Emergency calls only. After picking it up, about 30 sec, it registers 3 bars as normal. I am concerned that I am missing calls and text messages because after it turns on I get text messages. So, what is going on here? Any Ideas?

Odd data connection issue - Nexus 4 / T-Mobile

When I try to connect to a T-Mo tower for data al I get is an icon in the notification area saying "Sign in to Network" =. When I hit that I am sent to a T-Mo page asking me to sign in. I give it my credentials and press login but nothing happens.
I've talked to T-Mobile and they cannot find anything. They've sent me to Google. Waiting for them to get back to me. In the meantime I figured I'd ask XDA. So, any ideas?
Relevant parameters:
LG Nexus 4
The phone is bone stock Android 4.3
The SIM is new (about 2 months)
I can make calls and text on T-Mobile.
The SIM works in my old Nokia N97 phone and talks to T-Mobile Edge data fine.
The phone connects to ATT HSPA data fine when I put an ATT SIM in it.
The phone connects to data abroad.
Airplane mode is not on.
Data is on.
Roaming is on.
WiFi is off
Airplane mode is off.
I have wiped the phone and started from scratch, no luck.
I have tried in Safe Mode, no luck. (So it's not some odd App interaction)
I have told T-Mobile to kick me off the network and then wiped and restarted, no luck.
I have been through all the APN setting with T-Mobile, all is well.
I have wiped caches, no luck.
TIA

I'd look up the APN details on here for tmobile. Cant find a link at the moment but i know there are a few out there. T-mobile people usually have no idea...
It sounds like something on the carrier's end though. quick search brought up several topics on xda but no real solution.

It has happened to me as well, but my data still works. Sometimes I just reboot it, or put it in airplane mode and it will go away.
Unless u never get data.
Sent from my Nexus 4 using Tapatalk 4

this happened toe last night as well, lasted about 3 hours or so. it connected to the towers jist fine, sometimes the signal bars turned blue, sometimes not. but no data flowed through, neither via lte or hspa+. i called tmobile to check if they had an outage, they said no. i had them reset my data connection, but that didnt help. eventually data started flowing via hspa+, then via lte an hour later. i did all the troubleshooting, it wasnt an issue with the phone nor sim card. it was a tmobile issue for sure.

OnePlus 3T T-Mobile VoLTE issues/fix

I know this has other threads, but I wanted to post something that helped me get VoLTE working that none of the other threads addressed.
Quick background: new to TMobile, new to the 1+ brand. Rooted, stock. I could get LTE, but I kept getting kicked to roaming AT&T H+ or 3G, couldn't get VoLTE, and very slows speeds even when on LTE. Tried every APN combo, network settings reset, factory phone reset, tried every *#*#4636#*#* preferred network type...nothing. Chatted in to 1+ asking if I could speak to technical support. The response was the only way to fix it was to factory reset (which I had already done) and downgrade OOS. The newest OOS has the T-Mobile optimizations, so downgrading makes no sense! Needless to say, the whole 30 min chat was a waste of time and just a bunch of weak canned responses with no attempt to really help or figure out how to escalate me to someone with some knowledge of the APNs and settings needed.
Out of desperation, or since I had tried every other possible trick, I went under my T-Mobile SIM, Network Operators, and toggled Auto Choose and manually chose TMobile 4G.
Boom, full bands 4, 12 and VoLTE, and normal speeds! Carrier aggregation is even working sometimes.
I don't know why Auto Choose doesn't know how to grab 4G permanently, but everything is working!
Does anyone have any idea why this fixed it? Since I choose 4G, will I lose my ability to get 3G in rural areas? I don't feel like there was much info on how VoLTE is provisioned on the phone.
What's everyone's experience with the preferred network settings? I'm currently in LTE/UMTS, and I don't have the LTE/GSM option that apparently everyone else has...?
Also, does everyone else have as sporadic speeds as I do? One moment it'll be 40 down, next it'll be 6? I know it has to do with bands, but should there be a way to even that out a little?
Sidenote: I really like 1+ mentality about rooting and software, since I have to have a rooted phone, but this experience really soured my first impression. Plus their 1+5 is a major letdown to me. I don't think I'll purchase anymore 1+ products.
Feel free to correct any misinformation in my post.

I also have noticed when I try streaming, webpages or speedtests the little LTE+ carrier aggregation kicks in to combine band 4 and 12 and I get pretty good speeds. See screenshot

My speeds do definitely vary on Tmobiles network. Isn't an issue for me, everything streams fine, also i haven't had an issue with VOLTE since I got the phone in February..

I noticed when I'm in a roaming area, instead of roaming now, I completely lose service. I believe this is because I manually selected TMobile 4G as my operator instead of auto, which would allow the phone to jump to AT&T. Any ideas?

So still having problems, but only when traveling. If I have network operator on "auto" it'll select AT&T roaming, but then it'll just stick then and never switch back to TMobile, even in full strength band 4 or 12 areas. I have to reboot, and toggle auto for it to grab a T-Mobile signal. Very irritating. This also kicks the phone off VoLTE, and I've yet to get it back. Not sure if this is TMobile or the phone's fault. Tried everything I can think of. Any ideas?

Excuse my ignorance, but what would a new SIM accomplish, technically speaking that is?
FYI, my wife's HTC 10 does the same thing. That would make two bad SIMs unlikely?

I've had same problem as yours, I went to T-Mobile store and told them what was going on. They switched my SIM card and problem fixed. I was told because my SIM was too old (4 years at least) that's why i was having such issue.

New SIM, no change

Sorry to hear that it didn't work out for you. I attached couple of screenshots just to show you that it's been working good for me after I switched SIM card.
Edit: have you tried to create a new APN instead of using the default APN?
Edit 2: I can show you my APN if you want

Sorry, must have not been clear. I can get LTE, just not automatically after going into a roaming area. It just sticks on AT&T roaming until I manually go back in and select TMobile 4G. The problem with that is when I do need roaming to work, it won't because I have TMobile 4G manually selected.
Another problem is that I can't get VoLTE to stay very long, in fact i haven't had it for a couple days, despite me being in a very strong LTE area.
I appreciate your help
Edit: yes, if I could see your APN that'd be great!

Just create a new APN exactly as mine and see if it works

Hmm yeah that's the one I have too....
Btw, maybe I just needed to wait,, but VoLTE is working again, and it's reporting the correct IMEI (it wasn't before but TMobile told me that wasn't a big deal...I beg to differ because now my TMobile app is working whereas before it wasn't) Fingers crossed the new SIM did the trick! I'll know tomorrow when I commute to work and it starts roaming whether it'll reacquire T-Mobile and VoLTE

Quick update: I definitely have noticed an improvement in jumping off AT&T roaming back onto TMobile LTE. AND VoLTE is now sticking. But... I'm inclined to think it's something related to me not having my second Verizon SIM in. I have a company work number on a Verizon SIM that enables me to text and call from that number. Obviously data doesn't work but that doesn't bother me since I have TMobile unlimited on my personal SIM. When I insert my Verizon SIM in the second slot, my IMEI number changes in the testing menu, but not my settings info! What the heck? The IMEI number identifies the phone and shouldn't change...I thought? Very confused why part of my phone retains the correct IMEI and the testing changes. I instantly lose VoLTE and my TMobile app fails to authenticate.
What is going on???
UPDATE:
I popped my Verizon SIM in again (slot 1) and it's reporting the xx...15 IMEI (correct one on my T-Mobile account) and the T-Mobile SIM (slot 2) then drops to xx...07! I'm so confused! I thought the IMEI is NOT supposed to change because it identifies the device?? The ICCID is the SIM number? Why is Verizon SIM screwing this up?

Lost LTE on Verizon

Ok... I screwed up! There is a new Verizon tower near my house and I wanted to update my roaming, so I did the *228. Alas, by accident I chose option 1 (Program phone) instead of option 2 (Update roaming). Immediately after that I lost LTE. 3G is the best I now get.
I am running 7.1 latest update. Not rooted.
Suggestions on how to get LTE back up?
Thanks!

Try this:
*#*#4636#*#*
Phone Information
Change Preferred network type to LTE/WCDMA
If after cycling your connectivity it doesn't pop onto the Verizon 4G network, reboot your phone, you should be good then.
I dont know what it is about that setting that is different, because Verizon doesnt support WCDMA, however this seems to select the correct type of LTE connectivity and you'll be in that. Be aware though, this will likely prevent 3G from working if you enter an area without good 4G coverage.

I have tried all recommendations. LTE works for a while then it is back to 3G. On a further note, when this happens I cannot send a text message but a reboot will solve the text message issue.
I am at a loss. It seems there is no way to make the settings accessed by *#*#4636#*#* STICK.

It not just you. I have been frustrated for weeks. I thought it was only because I upgraded to 8.1 but your situation just answered that. I just ordered a new SIM from Verizon and wont run any programming once I install it. I contacted Essential on it as well as others. I hope the two can work this out.

Best option is a new some. *228 is usually no suggested on LTE unless you really know what you are doing. The PRL should be automatic on LTE.

get a new sim, your is borked now most likely

Will try new SIM tomorrow and let you know...

A VZW rep had me do *228 when I was having some issues with texting when I first got the phone. Fixed the texting issues but then I couldn't get LTE either. A new SIM fixed both issues I was having. *228 is apparently known to bork VZW LTE.

Had the same issues after using the *228 method I advise not using that at all been stuck on 3g since. Getting a new sim thursday hoping that helps (using straight talk Verizon Sim)

Here is a bit of information I have discovered. The phone is stable as long as I NEVER turn on WiFi! IF I have WiFi turned on (no connection to a network required) AND I enter a poor or non-existent service area, I loose service until I go back in with the *#*#4636#*#* and change settings back yet again!

anyone with a new sim got it working? Verizon shipped me one today and put it in. Avoided calling 228 but cannot get the sim to activate itself.
Got a SIM not provisioned error. I turned it off, took the SIM out and checked it, put it back, rebooted and still nothing. Not connecting to Verizon Network. Im afraid to call support because they will insist to call 228 to program it.

BTW the final version of 8.1 fixed all the Verizon weirdness I had going on. I popped it back in 'Global' in the Mobile Network settings (which is equivalent to 'LTE/CDMA/UMTS (PRL)' in the Phone Information section) and it hopped immediately on to Verizon, no kinda looking like sprint, no blank, no need to dial *228 for a new PRL it just worked. In fact on reboot it doesn't sit there with No Service scrolling across the screen for 15-20 seconds after boot, it shows up Verizon Wireless immediately.

That's good to hear I switched to an old straight talk TMobile sim I had while I wait for the replacement straight talk Verizon version hoping things go as smoothly for me when I pop it in

May you should try reinserting your sim my phone self corrected once my update was done.

Here are my results:
Installed new SIM - same issue
Did a network data settings reset
Verizon did a flush and reinitialize of my account.
Still same result.
Don't know exactly how or why but about 10 mins later I noticed my phone was OFF.
I powered back up and MOST issues we're gone.
The final fix was to go into developer options and turn on "cellular data always active"
Working great on LTE+

Try putting it in "4G/LTE", wait for it to connect, then back to Global.
After I posted my above message, I did go mucking around in the settings and got it stuck in 3G (even after reboots, etc), then corrected it by doing this.
And quick clarification for the post above this one, it is "Mobile Data Always Active", mine was already on and I never modified it, so that must be the default.
