Not even getting 3g on att

Got this phone yesterday, had no data plan previously so I had to get one. Went into att store to get micro Sim and data plan. It took forever because n4 imei wasn't in their system and giving them the number lead to further confusion. One hour later I ended up with a working Sim and they entered a generic imei number. Calling and texting works fine but I'm having data issues. I sometimes get HSPA but then the service drops back to edge and never comes back to HSPA. Rebooting sometimes fixes, but most of the time it gets stuck on edge. I know my area has great HSPA and 3g coverage because my friend has an hspa phone. Is there something I can do to fix? Or if I call att, what do I tell them to do to fix?
Thanks.

Just wondering, what data plan did you get?

3gb $30 a month.

You made sure to set the APN correctly?

How do I set the APN? I'm new to smart phones, att just handed me the phone after putting micro sim in it. I looked at the mobile network settings and I'm not sure what they should be set to.

Turn off phone, take out sim card. Blow on it or do whatever voodoo you prefer. Put back in and turn phone back on.
Report back.

Changed APN settings to match this and rebooted. http://forum.xda-developers.com/showthread.php?t=1791526
Getting HSPA+ now, I'll see if it stays that way.
Thanks.

Go into APN settings, tap menu, then restore default APN and see if that helps

You should be able to get unlimited data for $15 because its not a smartphone thats in their system as you said. So, technically, its considered a dumb simple phone, which gets the data plan $15 or unlimited text and data for $20. I was planning to get this plan once I receive my back ordered device...AT&T probably put you the smartphone data plan because they saw it was a smartphone. I would call the ATT customer service and re-give them your IMEI number to get the unlimited data.

Their system was detecting it needing a blackberry plan, trust me, I tried getting the cheaper one. And apparently after a couple of months they will figure out you are using a smartphone.

you dont need to do that. the phone automatically assigns the att one.
atleast mine did

Turns out I did. Atts network gave me the settings for edge and I had to change it manually.

I did that with my current phone, and now Super Mario loads properly. Thanks!

Now it appears when I reach a low signal strength area I get edge and once I leave that area it doesn't transition back to HSPA+. Anyone else having this problem?
Edit: I've tried a bunch of APN settings found on this forum and now I'm not even getting HSPA. WHYYYYYY?

Force WCDMA (UMTS/HSPA) Only
My Samsung Vibrant had issues staying on 3G, and this solved the problem. So here's how to force it to only use UMTS/HSPA. Phone -> *#*#4636#*#* -> Phone information -> scroll to the drop-down list -> select "WCDMA only" -> wait for it to apply, then enjoy 3G. To enable EDGE again, select "WCDMA preferred"

Verizon Note 4 on t-mobile network

I've been using it on tmo since yesterday. Solid signal, very stable so far. I ran speedtest this morning and got 56 up\26 down. The speed is crazy fast.
To get the Note 4 working on Verizon:
1. Change the APN setting.
http://support.t-mobile.com/docs/DOC-2090
2. Change the network mode to Global in Mobile networks (same place where you set the APN)
3. Change the voice mail number.
-Open the Phone app, click on the 3 dot Menu button, go to Settings, select Call, select Voice Mail Setting, and change the number from *86 to 123.
-I use Google Voice, so I just switch mine to Google Voice.
4. If touch tone DTMF is not working for you, try to turn of noise reduction or change the DTMF from Short to Long.
5. To get rid of the annoying SIM message in the notification. Tap, hold the message and select App Info then force close it. Do this every time you reboot the phone.

Hi, noob question here, I am also using tmo network on a verizon note 4 but I can't seem to go online... I was told to changed the Network mode to GSM but still nothing. it also says the Signal strength is -67 dBm 23 asu. Any help would be great thanks!

You need to add T-Mobiles APN google it!

Good to know. I'll be taking this bad boy to Asia next month. Sounds like it'd be a no problem sticking a new sim card as long as I get the APN down ?

how to remove Verizon bloatware
I'm using the Verizon note 4 with the T Mobile SIM card and it works well, it connects to 4G LTE, but I cannot use mobile hotspot because its integrated with Verizon's services. All the APN settings are fine but it says mobile number not found.
Does anyone know how to remove all of the Verizon bloatware? Things such as the Playstore and settings even have Verizon bloat. Data Usage tool also does not work either.
Also to note, whenever i reboot the phone a permanent notification apoears saying something like, "Sim card is not Verizon," which can only be removed if you force close the activation agent. Its annoying that Verizon left its mark throughout parts of the phone.
Is it possible to make this a Regular galaxy note 4?
(Another weird thing is that the settings menu cannot be switched to carousel mode which the T-Mobile version can do.)

hi i tried my t-mobile sim in my verizon note 4 but lte is not working it only works on hspa
so what apn settings did u use can u pls tell me the apn settings for lte.

I think T-Mobile sims for lte should use
fast.t-mobile.com
also make sure you do have LTE in your area.
I did it on Galaxy S5 for someone and it was fine.

To get rid of that notification, press and hold it until the App Info window appears. Hit that window then you'll go to the Activation Agent app settings. Push "Force Close" and it will disappear.
Nice and easy but the only problem is that you have to do this every time you restart your phone.

Does your phone have a clean esn from verizon or is it considered a "bad esn" (lost phone)? Just curious if they work outside verizon with bad esn.

It depends if your market uses LTE band 4. Probably though.
Also, it looks like (once root is achieved) you'll be able to add more LTE bands.

Do we lose frequencies when we use a verizon phone on tmobile? Doesn't seem to have band 12.

Shouldn't be an issue since AT&T and T-Mobile primarily use band 4. The other bands are for additional bandwidth if there is congestion and T-Mobile uses band 12 in limited markets.

Sprint Preordered SM-G950U MSL

So just wanted to let you guys know at least this worked on my end. If you have the SM-G950U preordered S8 and using Sprint, you can edit MSL settings.
1. Go to diaper and type in ##3282#
2. Either view DATA or Edit
3. Type in '000000' as your MSL Code.
Don't know if you can really change too much but I'm going to play around a little.
Let me know if this is helpful to anyone or if anybody has any further suggestions or comments.

Worked for me also. Thanks for the information.

I got it still can't edit the APNS

Yeah not sure why we can't. However, interestingly if we try to access APN list via settings - connections- mobile networks - access point names, I can see a list of 7 APNs. I assume most are only used for OTA updates and if you set your connection. From cdma/LTE mode to global mode. If I then go into DATA Menu and edit mode and click on the APNs then I can only see 2 options (EHRPD or LTE) but I am able to select the one I want and change it. However, I do see that I don't have the option to add a APN. This might be a limitation when using Sprint as the carrier.

Well the thing is that I have a sprint Galaxy S8 with i bought "unlocked" to my surprise it wasn't I have ATT. So im looking to whatever i can t get this cellphone unlocked!!!! Since I don't have a Sprint SIM. I can't edit APNS on settings!!

Hmm well I figured you probably already tried this but earlier if I went to Settings- connections - mobile networks- network mode and changed to gsm/umts I was able to then click manual and search for network and connect to either AT&T or T-Mobile. Not sure if this Must be done first.

I went to Settings-conection- I don't have mobile networks here.
I don't know if you need to have a sprint sim for this. But right now I don't have any sim because Im using ATT and using a older phone to be able to have a phone!!!

Okay so I just tried this option. Go into the connection and network mode and change to automatic. Then had to restart. Once restarted I went back to network mode and changed to gsm. Then I went to network operators and searched for network. Got the error that it must kill data connection before searching. I selected ok and searched. Att and T-Mobile came up. I selected Att and it said it registered on AT&T. I don't have an AT&T SIM so I can't test. However, in the morning of I see my roommate I might be able to try his SIM.

Also you might have to select gsm mode and then do the ##3282# and edit mode first and then go into settings to change network operators. Not sure but it seems ##3282# edit mode must be done to unlock additional settings in the phone.

Don't have conection mode either. I'm thinking you have this enabled because you have a sprint sim in it!!

Did you buy the phone already activated on Sprint network? And also it is a G950U correct? The only reason I ask is because I think the G950U is unlocked but if it was already activated on Sprint, then you might have to factory reset the phone and have the AT&T SIM inserted to have AT&T be your carrier.

I don't know I bought it from somebody locally who said it was unlocked and yes it says G90U but when I insert the sim card it says invalid sim card.
Let me try the reset with the AT&T sim in it to see

When I first turned the phone on it never had the Sprint splash screen until it finished setting up and power cycled. That was the first thing I noticed. Also the phone should be unlocked by default bc this variant is exactly the same for the 4 major carriers. When I checked the firmware both CSC and AP it was the exact same as T-Mobile firmware.

Please let me know if that works. It is just a suggestion and there is so much confusion on this at least from my part. Not to mention not much info on the forum yet. If this works then it might shed some light on the G950U variant.

Does not work. Is says please provide the UICC that came with the phone. So apparently when you activate it with a provider it locks!!

Sounds like it might SIM carrier lock. I think the law last year stated that we have to be able to swap phone on any carrier in the US. There is a UICC unlock under settings and software updates but it wouldn't work for me. If I remember properly I had to wait about a month or two before they would let me UICC unlock it. On samfirmware there isn't an AT&T firmware uploaded yet. There should be soon. You could try to wipe and use the T-Mobile firmware as this is GSM and will at least be the network of roam for AT&T. Might at least allow you to use the SIM or at least activate on AT&T

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?

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?

How can i force the OnePlus 6T to an specific network?

Okay, so I am on Verizon and I purchased the OnePlus 6T straight from OnePlus website. I have the 8gb ram and 256gb storage model. I have unlocked the bootloader but haven't installed a custom recovery or rooted yet. Just wanted to unlocked bootloader since it requires a wipe of device storage in case for the future.
Anyways, the phone works amassing, battery life is great, I had a pixel XL before this, screen is fantastic and is plenty fast but I have ran into an issue. The phone was activated on Verizon using Sim 1. Signal is not an issue, always have LTE from Verizon and way better signal than pixel XL ever had.
My issue is I live in a border town with Mexico and I just noticed that when I am close to the border, like within a mile the phone switches to Movistar cell provider. Movistar is a Mexican cell phone provider. Is not that I lost signal because my pixel XL had signal all over there before and the OnePlus 6T is stronger, is just that apparently the Movistar provider has a stronger signal on that area and the phone is choosing to pick up the stronger signal, even if it means going off and switching to roaming.
It doesn't cost me any $$ and speed is wicked fast while roaming but Verizon will only allow 0.5gb of roaming per day which limits the usability of the phone. Anyways, thanks for reading my long post, just wanted to give some context to the question and hopefully find an answer. Like i said, I did search and didn't find anything. If I have to root to install an add-on or an app that lets me pick my signal please advise. Also I know that I still have a strong Verizon signal because I used ltediscovery app to check and it shows the signal strength of whatever many signal phone is picking up.
Thanks in advance for reading and for answers.

One option might be Network Signal Guru in the Play Store (requires root). It's the only app I've found that allows the user to lock the phone to a specific band - which might help with your situation.

Outstanding sir. Thanks for the information. I guess time to root then for me. Been waiting for a stable recovery for OnePlus 6T but I supposed no harm so far using current version of twrp, as far as I have read.

have you tried going to settings, internet, sim, sim1, network provider, disabling the automatic option and selecting your preferred provider manually? this way you will stick to that selection

try to search for operator or network on the main options screen at the search bar on top.
if still no luck than maybe there is something wrong with your sim card or apn settings. you should try to contact OnePlus support than.

Mine does have network operator anywhere.
I look through all the settings and nowhere to be found. I am on Verizon network and only sim1 has a card in it.
Sim2 is empty.
I can get to the special settings through *#*#4636#*#* and even there changing different LTE settings keeps reconnecting to roaming network since the tower is like a stone through away.
Any other options would be greatly appreciated. Also the app that was suggested in 2nd post, rooted phone to try it and that option if it works is behind pay part and that app fee is $50/m. A bit steep for me so looking for options still.
Thanks in advance

Couldn't you just disable roaming?

I could but I only have an option for disabling data roaming, not roaming all together. I tried it in the past and all it did was kept me connected to the roaming network and turned off the data off of the roaming network connection. Meaning I had zero data connectivity.
I wonder if putting a Sim in sim2 slot would open up more settings ?
If anyone is using 6T on Verizon could you please go to wifi & network, sim1 and see if you get any more options than what I posted on previous ss about 3 post ago.
Thanks in advance

do you have a carrier locked device? that might prevent you from doing changes to your sim.

I don't believe this is carrier locked since I bought straight from OnePlus website. Hell, I was even charge a currency conversion fee by my credit card cause the purchased was in foreign currency.

you should try another sim (family or friends) and check if the missing option appears. maybe try your sim in another phone too.
lastly you could try a full factory reset (deletes all data)
at the end if it still does not work you really should call OnePlus for help.
also I found this app here: https://play.google.com/store/apps/details?id=com.pomo.android.networkoperators
open it and select "available networks"
that should open the missing menu to toggle operator selection...
