[Q] Stuck with a disappearing APN problem - AT&T Samsung Galaxy Note I717

Yesterday I bought an i717, an unlock code so I can get it working on T-Mobile, and put the newest Cyanogenmod nightly on it.
I noticed that my data speed was stuck on Edge and found out with some searching that this was common problem. I went to this thread and have followed it's instructions but now I've hit a wall and can't figure it out.
I've flashed both the radios that should work but am getting no working results. Can anyone offer me a hand with this? I would greatly appreciate it.

I don't have T-Mobile but suggest try different ROM. Also make sure have most recent twrp

I'll give that a shot, thanks

Thanks for the reply. I tried all that, new TWRP and all kinds of different ROMs but the problem persists. I did notice one thing however, and that was when the phone had the ROM flashed on it, brand new (like just after a factory reset), 4G worked really well. That is up until I turned the wifi on. Turning the wifi back off, and/or restarting, and/or clearing cache and dalvik will not get the 4G connection back. I'm at a loss. Also if I try flashing a different radio I'll have the disappearing APN problem. So for now I'm stuck with EDGE.
What other options could fix this? Could the build prop be making a fuss? I don't really know where to go.

It sounds like your sim isn't a 4g provisioned sim. The APN would stick if the sim was appropriate.

I think my SIM is provisioned, it works fine in any other phone from tmobile. in my gs2 I had it worked fine. that was a few days ago.

Tho I guess a new SIM card could be worth a shot.

This is "The Answer Post"
I got it! It was in the mobile network options. Since this is an ATT phone with an ATT radio I had to think a little differently, since I'm used to T-Mobile settings. The "Data Roaming" and "National Data Roaming" check boxes were unchecked. Again, being an ATT radio I guessed that these needed to be on. Once doing that I went down to network operators to manually select "T-Mobile" as my network. Once I did, voila! 4G connectivity now works like a charm.
Just wanted to let the internet know, in case someone else needs this.

Good save!

Question about 3G

After e-mailing AT&T and finding out that, "After reviewing the coverage for your area it shows that you do have the best of our 3G coverage", I can't seem to pick up anything but E..
So... do I have a problem with my settings or are they bs'ing me..?

If it is an AT&T branded phone and you have an AT&T SIM card, why would you think that your settings are messed up? Have you rooted your phone and installed a custom ROM? Even if you did, the custom ROMs that are available for the Aria should have the correct AT&T settings.

OK, first I would do a 'nandroid' backup to save your current configuration. Then I would do a Wipe Data/Factory Reset and then see if you can then pick up a 3G signal. Depending on which custom ROM you have loaded, it will either show up as 3G or H (if you are running CM7). If you still can't get a signal, I would take it to AT&T and see if they can figure it out.

Dial *#*#4636#*#* on the phone. A menu will come up. Select Phone Information. Scroll down a little bit and there is a dropbox that says "Set preferred network type:"
This setting should be set to "WCDMA preferred". If it is not set to that, change it to that then hit back to get out of the menu, and see if the 3G works after that. It might help to restart the phone after doing this.
If that doesn't do it, try finding someone else you know with an AT&T SIM card, and try putting it into your phone to see if you can get 3G. If it's a very old SIM card, consider asking for a new one.
Also, double check underneath the battery. Does it say A6366 or A6380?

It was already set to "WCDMA preferred" I changed it and changed it back and I'm still only able to receive E and under the battery is says, A6366
The application called Network by Phillip m. Allows you to set up for gsm only and so on. Works good.

Do you know someone else who has a 3G capable AT&T phone that can see if he can get a 3G connection at your location?
Also, have you ever gotten a 3G connection anywhere with your Aria?

Hmm, I'd have to look most of my friends are on Verizon and the ones on AT&T don't have data plans l:
Most likely I'm just going to have to go in to AT&T and no I have never gotten a 3G connection.

Sounds like a defect in the phone to me. If I were you, I'd probably re-install the factory default RUU. (Make sure you use the 2.1 one, NOT the 2.2 one. As long as you use the 2.1 one, you will still be able to root the phone again.) If you want to retain your current settings you can take a nandroid backup. After rerooting the phone you can restore it.
If 3G still doesn't work, get it exchanged. Was this a recently purchased phone?

Ok before all that, I just restored the nandroid ,from before when I was told to backup then wipe to see if I'd pick up the 3G, and after it boots up it just starts bringing up force closes of apps continuously... I can't do anything but force close the stuff that pops up.. (it seems to be all the apps that I had pre wipe that are causing the problems... I can't use my preferred launcher or even the keyboard [smart keyboard pro] that I had set, gmail doesnt seem to be working either)
Also this phone is a couple months old, I got it for free because I stayed with AT&T after they acquired the local phone company. It's not a huge problem that I can't get 3G as I can access wifi most of the time, but me and a friend were looking at T-Mobile and saw a joint plan we liked but I knew I wouldn't be able to receive 3G with T-Mobile, I then remembered I had never even gotten 3G with AT&T

Phone shows no network with working sim card in it!!

So I have a Note 2 and a HTC one, for about three weeks I used my HTC one and then i switched back to my note 2. Yesterday I wanted to use my HTC one but every time I insert the sim card I get a no service message. what can I do to fix this?
I did not root the phone BTW.
Have you found a resolution? I just ran into the same problem. Phone was working great, then one Sunday afternoon it just stopped getting a signal. It's not the SIM as it works fine in my old SGSII (had to make SIM adapter). I am rooted and unlocked and running non stock recovery but still on stock kernel/radio. Haven't contacted HTC yet for obvious reasons.
I've had this happen a lot with my phone on tmobile. I live in a concrete basement apartment where there's no reception and if the phone goes more than 15 hours without any signal I almost always(80%ish) have to call tmobile and have them deactivate/reactivate the sim from their end.
A fix you can try that they swear "usually works" is go to settings/mobile data/network operators/search automatically
If that doesn't work then try settings/mobile data/access point names/menu/reset to default
Apparently these settings can be reset pretty easily when the phone doesn't connect to a network for a bit, but all this might just be a tmobile thing
I have a bit different problem - I bought HTC One from T-mobile and unlocked it. I tooked it with me to Europe and device does work with american sim (ATT and TMO) but it wont recognize any of my national carriers. Insterting simcards(perfectly working) does not give me reception or anything. Sim cards are the same thing in EU and US I think - also those are GSM phones. I have friends having same problems with their S4 from AT&T in Europe. Does anybody know something to help make this device work?
OP - this happened to my Wife's phone for no apparent reason one day. I simply removed & reinserted the SIM and rebooted a couple of times, hasn't had a problem since.

I changed my SIM for a new one. Seems like a new SIM cards are a bit different from the old ones because after I did that I had no problems

Same problem here. I am on paranoid android though so maybe that has something to do with it. When I go into the settings to connect to the t mobile network, it says "your sim card is not authorized" or something like that. Maybe it's cuz I haven't paid my bill for 2 months? Lol but I don't think that's reason for them to block my sim :/

I had the same problem and I had to restart my phone sometimes several times a day, sometimes I had to remove the sim card enclosure and reinsert it in order for my phone to get a signal. So I contacted HTC and they told me that I probably had a defective sim card enclosure so they sent me a new one. After I installed the new sim card enclosure with the same sim card I had before the problem went away. I've been without any problems for the past four months or so since I got the replacement sim enclosure
type *#*#4636#*#* -> phone information -> make sure GSM/WCDMA/LTE Auto selected and Turn off radio
If you see turn on radio click that to turn on the radio. Is some cases the radio gets turned off and a reboot doesnt fix. This is the only way I know to recover it.
I've this same issue!
Did anybody found a solution?? I already tried everything... but seems like the phone is not blacklisted.. in case it is, something I can do? besides change my IMEI.
Thanks!!

Make sure your Apn is set up correctly. If you go to settings>Mobile Data>APN you can see your apn and compare it to other tmoblie ones

Radio chip
I wonder if anyone can help please. My M7 can't connect to the network. The radio isn't turned off, I checked using the code given by Shane_pcs, so I know it is a hardware problem. I suspect the radio chip has worked loose somehow and isn't making contact like it should. Any tips on how to resolve this please? I have seen a tear down of the M7, but don't know if anyone on here has attempted to secure the radio chip before...not even sure what the chip itself looks like. Any ideas please? Thank you.

Verizon Galaxy S4 no GSM signal

I've searched and didn't find any thread with this kind of issue specifically. I have a Verizon Galaxy S4 that doesn't seem to like GSM SIM cards; it looks like it is not GSM unlocked. I have tried every trick to get it to switch to GSM but it doesn't. I have flashed the same version firmware it came with (ME7) just to be certain it's factory restored, and also updated to MK2, yet no GSM. It sees the SIM card but doesn't show a signal, even when I manually switch to GSM/UMTS. I have programmed a CDMA number on it manually then tried the GSM switch again, yet no GSM signal. It sees CDMA signal fine though and can even make calls on CDMA. I even had to check the MEID/IMEI and it came back clean so I'm just surprised at all this. I have done this before successfully on a Verizon S3 and it worked well, how come the S4 has refused to work on GSM?
Please help, anyone?
Did you input APN's?
I thought APN settings had to do with data. I will do that now. I'm willing to try anything now.
Thanks.
I am having the same issue with a couple s4s from verizon as well. Checked the IMEI/MEID and they come up clean but they will not catch a signal with a gsm SIM card. I have tried several active AT&T and T-mobile SIM cards in the phones with the same results, no service/signal. Very strange as I have never had an issue with verizon S4s working on AT&T or T-mobile. The weird thing is that with a verizon SIM they catch signal and 4G just fine. Toggled GSM/CDMA and put in APNs and still no luck. I'll keep trying to work this out but right now I am stuck.
I had the same problem here
My GT-I9505 Rom Stock 4.4.2 ZTO(Brazil) had the same problem about signal problem.
Everytime i lock my phone (turning off the screen), by the time i light it on (lock screen), immediatelly my phone turns the signal to "No service".
In this time, i need to wait 1-2 minutes to the phone turns okay. Just wait.
I search for a lot of solutions and didn't find anything.
Notice too that the problem appears only network 2-3g. 4G didn't have the problem.
I solved this problem after Lollipop update. The problem simple dissapear!

Internet settings for Life Mobile (EE) in UK

Hello there,
I have been using Tesco Mobile with my Redmi Note 2 for a couple of months now and have had no problem. I decided to switch networks to a VPN called Life Mobile. They use EE's network in the UK. Since putting in the sim card today I have not been able to connect to the mobile network. I am wondering if anyone else on this network with this phone could help? I have called Life Mobile's helpline and all they wanted to do was run me through EE's apn settings. I had already used their app and also searched elsewhere on the web to find a few different APN settings but none of them worked.
One thing I'm wondering about if whether or not the custom ROM/firmware (MUI 7 I believe) that the phone shipped with (bought online from China by the way) is having anything to do with the internet problems. I get the feeling the customer service for Life Mobile were fobbing me off when they said that maybe my phone just isn't compatible with their network. Phone calls and texts work fine by the way.
Does anything think flashing the phone to the standard android ROM that's available would have any affect on the internet settings. I'm no mobile expert, and with the phone not being on general sale in the UK yet as far as I know, I would appreciate your help to get this internet/mobile data settings issues sorted, as I do use my phone for work.
Thanks in advance for comments and help.
I definitely know that the ROM that came with my phone from Gearbest was the worst piece of software that I have ever used in my life... ever. Check your MIUI build number and see if it's something like 5.xx.xx or 7.xx.xx. If it's something more like 77.55.66, then you have a knock-off and it may be eating your battery, performance, and experience (the original ROM Gearbest flashed on my phone had so much bloatware that the antivirus warned me about one of the programs every ten minutes, and heated up significantly on the home screen). If you have an unofficial ROM, try flashing a developer weekly or stable.
Hi all.
Well, would you believe it, I have spent a large part of the day trying to figure this out and finally I've done it. I'm not quite sure how but I've done it. I'll explain briefly to help anyone else who may be facing the same problem. It seems that changing the network preference setting within the sim settings from LTE to 3G did the trick. Life Mobile does not support 4G as far as I'm aware. That's no problem for me as I'm perfectly happy using 3G when necessary. After doing that and fiddling with the network settings, eventually reverting back to the automatic selection of the network as EE and using the APN default settings as given by the sim when it first was entered into the phone, things suddenly start to kick into life and we had INTERNET!
Thanks for your help in resolving this, and happy New Year to everyone.

Driving me crazy as well (on a Lenovo K3 Note). Still have the Tesco SIM in there. Was going to port the number on Monday, but might get them to take the damn thing back!
Tried all the suggestions above, but nothing working. Tried both SIM slots with and without the other SIM, but nothing. Grrrrr....

Well, they sent me a new SIM card and I had all the same problems until I switched on "data roaming" and it now works fine (it didn't do anything with the last SIM though, when I tried it in another phone, I had to have date roaming on in order to even get a regular signal- data still did not work). I have seen transient "R" occurring when the SIM was activated/deactivated so had suspected this as a problem.

Question Will TMobile sim work in new metro locked n20?

I know with the op n200 metro version you could put your T-Mobile sim in and unlock the phone to work with TMobile automatically, I can't find confirmation anywhere if this works with the n20 as well, does anyone here know?
I just tried with a T-mo sim card in Metro by Tmo N20 and it didn't work

Was the n20 brand new and the T-Mobile sim inserted before turning the phone on the first time? I read that's how it works on some older phones, I think metro blocked it finally but was hoping it might still work.

yes, I received the phone in mail this afternoon, Brand new and first boot was with T-mobile sim, no service and Mobile network status showed "Disconnected"
The Boot animation did change to T-mobile on a reboot with the sim inside but still no service
As I was playing around with the phone, I stumbled upon a weird way to get signal by trial and error got 4G and 5G data as well but when Wi-fi connected, data seems to switch back to 2G. Let me know if you want to know how

Sure, here it is:
1. Boot the phone with T-mo sim inside the device, once booted you wouldn't have any signal
2. Go to "Sim info & settings" > "Preferred network type" and choose "2G/3G(Automatic)"
3. Reboot the device, once booted you should see signal along with 2G icon
4. Now go back to "Preferred network type" and select "2G/3G/LTE(Automatic)", you should now have 4G (Texts and data works but call dropped)
5. Now switch to "2G/3G/LTE.5G(Automatic)", you should see 5G network (Texts, calls and data all worked fine)
5G was stable for several hours until I connected to Wi-fi and when I disconnected Wi-fi, I noticed that data said 2G.
Let me know if the above steps worked for you

Did you get an incompatible SIM error, or just no signal? Also, you can't just put a Metro SIM in a phone and have it work. You have to call them and tie the IMEI of the phone.

OP is talking about the other way around, T-mo sim in a Metro device
Nord N200 had a bug where the device could be locked to Metro but worked flawless with T-mo sim.
That bug being patched is what OP meant by "blocked"

Yeah, I got that backwards. But if he's not getting an incompatible SIM error with a T-Mobile SIM in the MetroPCS phone and actually getting an edge signal, maybe add a new T-Mobile APN profile. Should work in theory.

Thanks! Good find! Yes I was able to reproduce the behavior. Also in my case it seems that the 5G/LTE will revert back to 2g after some idle time. But I can use the airplane mode to repeat the process (without rebooting the phone) to repeat the process. I was able to reproduce on another metro phone as well. must be some kind of loop hole.

I know I already mentioned this, but did you try making a new T-Mobile APN profile and deleting the old one(s)? Maybe you wouldn't have to go through that ritual. might work, or not.

I just factory reset my device and tried this, deleted existing APN and added T-mo APN, doesn't seem to work
I take it you're not a MetroPCS customer. Must be something baked into the OS. I wonder if it still has the MetroPCS bloatware since it booted with T-Mobile boot animation? Anyway, there are services on eBay that will unlock this phone through the MetroPCS unlock app. I'm not selling anything just letting you know that's an option if you didn't already know.

It installed the T-mo bloatware and removed metro bloatware as soon as it booted. Yeah, I'm not a Metro customer, I'll usually just leave it alone for 180 days and unlock it afterwards

Ah, but you need active service on it for those 180 days to be eligible to unlock it no? And now that it has T-Mobile firmware how can you unlock it from Metro? I'd download the MetroPCS unlock app from the play store and run it to see what it says.

In theory, it's 180 days of active service but in reality, they've been unlocking 180 days after activation. I pay for first month and then throw it back in the box.
Also, I didn't see the unlock app as part of bloatware, its built into settings > about. It'll pull up the same screen as in Unlock app and we can try to unlock from there but obviously, throws the error showing it needs 180 days of service to unlock and is not eligible currently

On eBay it's 75 bucks to unlock. Thats like 2 months of service and you'd be able to use it in a few days instead of having a paperweight for 6 months. Thats what I did on my old Moto One 5G Ace.
