I am on the old $39.99 ATT plan the one that does not have 3G and my with an old “blue” SIM card. I have been using Sony S710a for the past two years which in fact worked fine. A week ago I have obtained ATT Tilt (HTC 8925), unlocked it so that it would read my card and started using it.
Here is the problem that I can’t solve>
Sometimes my phone loses service, completely, and I cannot reconnect to ATT Service. I have tried to find a pattern but so far I am clueless of what might be causing it.
According to my observation:
1. It has been happening in certain neighborhoods.
2. When I do find service and connect to it shows E and then switches to 3G
3. When my phone starts to show 3G it loses connection.
This phenomenon happens only from time to time. Other times I have 3G icon and everythign is fine. I have tried T-mobile card in it and there is no problem. It connects to T-mobile service and has all bars. Thereafter I have put my card into an unlocked Nokia 6300 and my ATT connection works fine. The only thing I can blame is 3G.
Please if anyone knows what this, why its happening and how I can avoid this issue let me know. Thank you.
it looks like I have got a solution...
Im not sure yet, but so far I have installed an application that supposed to keep me away from [3G]. The application that I have installed is Bandswitch. So far it only shows [E] . I have to travel to those areas where I had no service to be sure that this program works. Ill keep you updated on this issue.
go get a new sim card. ATT and Cingular towers were different so some older sim cards have trouble connecting to some towers. its only something like 15 bucks.
when i went to the ATT storeto get my tilt, even though i already had a 64k sim they still upgraded the sim (for free seince i was about to pay 400 bucks).
Its your sim card
The old sim cards don't have enough memory. Get a new one with the 3g logo on it. You should probably upgrade your service too. Or you'll get a big surprise when your bill comes.
I have the same problem here in germany with the O2 3G Network... My phone has a GPRS Connection and when the 3G Icon appears there is a total loss of connection for like 10 seconds and its back to GPRS again... End of the story (like i assumed and wrote to O2 ;P) my SIM Card is too old, new one on the way Should work for you as well, like all the other posters before me claimed
Edit: Oh and it didn't cost me one buck, all inclusive service because i didn't lose or broke my SIM Card. When it is too old to be able to allow you to use your full contract properties, i guess they pretty much have to send you a new new SIM card for free. At least here it works this way
Thank you...
The problem is that I dont have a contract and the only way for them to upgrade my sim to 3G is when i sign up. Curently I have 1000 min, nights and weekends from 7pm, free mobile to mobile, free long distance and free incoming SMS. Its highly unlikely that any one of you would give that up and pay more money for less minutes and less services. Right? Thank you. at this point i think im fine with what I have got, in addition to not needing 3G at all. by the way, i think that this program Bandswitch is doing a good job keeping me of 3G. Thank you.

I never had to 'upgrade' my sim to 3G, nor sign a new contract. I just took my old GSM SE phone in to ask about service, and they asked if I would like a sim swap to the latest.. Sure, done.
Now works fine with the Kaiser, and never did any form of 3G 'upgrade'.

Were you part of the old ATT Blue network? Cingular actually started giving out 3g cards in early 2006 in my area. I got one with my 8125 where they FIRST came out. So it's possible if you've gotten a phone since then and now that your card is already 3g...

You're right, I think it may be important to be on the 'orange network' because 3G never existed for the old at&t wireless 'blue'.
I was always part Cingular, and did go through the free-sim upgrade, but got another one when I just walked in after that.
Well I'm in malaysia, Using Maxis 3G network. I also having problem same symptoms like you guys. What do i realize sometime it give my device freeze for sometime. But the freeze just like for few second. And what do i realize when 3G appear our phone signal become weak. From full bar drop to 2 or 1 bar.
Did u guys having this issue too?
My simcard is 128k if im not mistake.
See this: http://forum.xda-developers.com/showthread.php?t=335074
Most likely the same problem. RMA ahead.
Try this on your phone settings (dialer --> menu --> options) on the network tab is network selection set to automatic? i was experimenting with my phone to see if i could get a better signal and set it to manual and choose my network but when im no a 3G connection its called 3G T-mobile and when not its just called T-mobile and on the manual list its just called T-Mobile so each time i got a 3G connection it would lose signal completely and start searching for i think T-mobile not 3G T-mobile the moment i set it back to Auto and soft-reset it worked fine again.
my phone did this at first, and all i had to do was get a new SIM. they didn't charge me a dime for it at the att store, but if they ask just tell them your phone won't connect and that it's a problem with your SIM
I have the same problem and have a new phone on the way. I already have a 3G sim card.
When you call, they'll probably make you hard reset your phone. Just a heads up.
So I put my SIM in from my g3 (which was T-Mobile and getting great lte) and phone was working fine then for some reason reverts to 4g and no lte. Check my account online and my phones imei shows up as an old blackberry which downgrades my plan automatically.
I can stick SIM back in old phone get lte, switch again and it reverts. Called and customer service can't seem to help. Anyone else with T-Mobile note on att having issues ?
I have been having a different issue. Every couple of days, I would loose all T network connection as the APN "ATT Phone" would become unselected for a as of yet undetermined reason. If I select it, everything works just fine (include LTE) till it unselects itself a day or two later. I cannot determine the cause.
If I look on my account it shown some "dumb" phone whereas I used to have a Note 2. I do get LTE. I use these APN setting, which seem to show up as default when I press the reset on the APN menu:
Name ATT Phone
APN phone
Proxy Not set
Port Not set
Username Not set
Password Not set
Server Not set
MMSC http://mmsc.mobile.att.net
MMS proxy proxy.mobile.att.net
MMS port 80
MCC 310
MNC 410
Authentication Type None
APN type default,mms,supl,hipri
APN protocol IPv4
Bearer Unspecified
See if these are the setting your SIM selects. If not, you can try unselecting "ATT Phone", change it and select it after saving. But perhaps you need a new SIM which T should be happy to give (or maybe it is a couple of $) you if you visit a store and say you lost your phone and the sim.
Thanks for the input. Yes I have tried deleting apn settings and adding the ones like you listed. It didn't help. Get 4g but no lte. Went to att they pretty much just said too bad it's not our problem cause it's a T-Mobile phone.
So far no issues running it in Manhattan for a couple weeks - I can't tell the difference between this, my OnePlus One, and my old AT&T Note 3 - all using the same AT&T SIM.
I did get some slow data speeds while in Williamsburg last weekend, but my wife's AT&T iPhone 6 had the same issues so I don't think it was a phone issue.

Oh okay. I don't know why mine is having this issue. Have used several T-Mobile phones on att without issue
Sorry to say it appears the Note 4 is polled or "phones home" and immediately shows it's non-approved IMEI. When I change the SIM from my T-Mobile Note 4 to my ATT Note 2 the MyATT page almost instantly changes from BlackBerry7100 to "Smartphone". Not sure what to do because it'll surely cost my LTE speed.
I've been using a T-Mobile Note 4 on AT&T since the week it launched without these problems. I have a feeling I'm jinxing myself or that it's only a matter of time before it does happen. What's weird to me is that on the AT&T page it shows I still have my old LG G3.
Are you guys using custom ROMS or Kernels or anything? I have pretty much rooted from day one and froze a bunch of stuff and immediately got rid of the Carrier IQ.
Well let me chime in. I never got lte on the note 4 until I got tired of slower speeds haha. I had an iPhone so I went to at$t to get another sim card but brought my s3 so they wouldn't know of the note 4. Problem I think was putting it straight into the note 4 and not settle into the s3 first and get all required info. So I was without LTE for a while until I decided to try again for it. So I called at$t and told them I was not getting LTE on my phone 5s so they changed the imei # to the one for the 5s. Still didn't get any lte so I went to an at$t store when they said to pick up a new sim. I used the iPhone probably for about an hour and got LTE. So from that point I put the nano sim into the note 4 and now I've been getting lte for over two weeks and great signal coverage. On my account it says I'm using a dumb phone but when I go into upgrade options it says I'm on an iPhone 5s.

And yes I'm using a nano sim not the usual micro sim
Hey guys,
Picked up a tmobile N6 today and successfully activated it on VZW. Had to cut my S4 simcard to fit. Everything seems to be working well (other than voice and data at the same time nbd) except LTE speeds are painfully slow. I'm getting a lot of time outs while loading play store, etc.
Any ideas how to fix this issue? I am in an area with a strong LTE signal. WIFI speeds are normal.
Don't tell me this. I just ordered the T-Mobile unlocked version for my Verizon line. I already have a nano Sim because of my current device. Maybe its something to do with the mobile data settings? Have u checked ur settings?
Maybe its your sim card?
I trimmed my Sim card as well and have no issues. I did have the Sim card in before the first power up though. Maybe a factory reset.. Bought mine from Google though.

sounds like your local providers issue today. 1. you are connected to verizon. 2, you are receiving data. so your connection is actually fine. the issue is with your local data speeds. try calling your provider and asking them whats up, if it is not the way your network is normally. they could just be having an issue today.
Update:
Not having the issue anymore. Just had to do a couple restart and the speed issue was resolved. I was thinking maybe a network issue but my wife's S4 wasn't experiencing the same problem.
As crazy as it sounds, I was experimenting with roaming ability and did a *228 and #2 on my phone with Verizon. Since I did that LTE went away all I see now is 3G
Did not change the APN only have one and set on LTE for network....
Could I have messed up my PRL but I thought the PRL is now on the SIM?
whats a *228 and a #2???
*228 is NOT supposed to be used with a 4G SIM Card, you may have broke your SIM.
This hasn't worked on any lte device, why do people keep trying it? You need a new sim.

Sounds like my man is right has broken the sim even putting it in iPhone still comes up 3g when it did LTE was the same phone I used to get a nano sim. Off to Verizon see if I can get a new sim.

I knew this was a bonehead move thinking I could get volte work after updating radio. Cause not listening to my inner man!
Similar thing happened to me as well, after I updated to 5.1. Worked good for a day then all of a sudden I couldn't receive calls no more. I could make calls, text and use data. I called Verizon and they reset some things and the service completely went away, then we got disconnected. After calling back the rep said my sim got broken somehow and told me to go the Verizon store and get a new one. i think the first rep disabled something and couldnt get it back on.
New sim was activated in another phone then put into the Nexus 6 and all was good. Funny thing is I didn't do the *228 thing and my LTE was still showing when I stopped receiveing calls.
Long story short. I was using a Verizon branded note 2 on straight talk when my contract ended with verizon. I grew tired of the phone and purchased the blu vivo xl from amazon a few days ago. Now I know that my sim in my Verizon wouldn't work on the blu phone because it's not compatible.
So I went on chat to switch my Verizon sim to an att sim from the same byop package (which also came with a tmobile sim) They said that it could take anywhere from an hour to 2 days to convert over, and that I'll know when it happens because my note 2 will stop working. Sure enough it stopped and a bit later my blu phone started getting a signal and 4G icon.
However, it was in and out all night and since then I haven't got it back. Frustrated, I then switched it to the tmobile sim. I get the 4G lte icon and arrows move up and down. My signal goes from 2/4 bars to 3/4 bars. Now I'm thinking good that's more than what att was able to do. Wrong. Well not completely.
I can send a text and my wife will get it. Not really slow but not normal. She'll reply and I can receive it. But I can't access the internet, and I can't call or receive calls. Went on chat they gave me apns to input and still nothing. I still get 4G icon and I still get service.
I really like this phone but this transition has been really draining.
Thanks you for your help.
I have no idea, I had a really smooth transition activating it onto metro. Maybe you just have spotty coverage with straight talk in your area? I'll try looking for more info

Correct. The phone is loaded with apns that matched what they gave me. The straight talk for att and tmobile.
So as an update, I bought a tmobile sim, (not straight talk this time) the phone received texts from tmobile for this and that. I have good signal as indicated from the bars. 4G lte icon is on (but no data due to not having a tmobile account, but the sim is allowed 30 texts and 30 minutes of talk time until I get one)
The problem that is persisting is that I cannot make a call. I'll dial any number between my wife's, friends even my own and it just gets stuck on dialing. No operator or anything just blank. It's flashing "dialing..." but it won't actually go and do anything.
I contacted blu, and they gave me the same apns that I used and assured me that it should work on straight talk. But yet still nothing. I contacted blu again after I got the tmobile sim. I'm awaiting an answer on that before I proclaim the phone a dud and exchange with amazon.com.

StraightTalk is owned and operated by Tracfone. I went through more blood pressure pills dealing with them than almost any other corporation. Best bet? Switch to almost any other carrier. I use Airvoice, but there are a BUNCH of others out there with no contract, pay-as-you-go programs. Truly, there are better deals out there than StraightTalk/Tracfone.
You are having issues (I think) because different phones available through Straight Talk work on different networks. They ask for your zip code and then show you phones from different networks that will work in your area. If you use a SIM card you are AT&T or T-Mobile. Sprint and Verizon use CDMA. Check coverage maps. This will explain why your coverage is spotty now. There is a list floating around out there that shows which networks use what phones and so on for Straight Talk. Once you put the SIM card in the phone, it picks up whatever network is available in your area. If it's a network that doesn't have great coverage where you are, service is diminished.
