Touch Pro 2 Network Freakout.

Ok, heres the skinny. My Fiancee got a US Cellular Touch Pro 2 off Craigslist, I flashed it and made it work on AT&T. It was working wonderfully on AT&T for a few months now, but just a few days ago, it started to freak out. It of course worked fine when I was around, but as soon as she left, it started to not work. This is exactly what she told me is happening:
"As for my phone, it still completely works except for not getting a signal. Or something. It technically says it has several bars, but it also says "Digital Roaming" where it used to say AT&T. Now that I think about it, it did say U.S. Cellular when the problem first started. When I try to send a text it just says "SMS Error" and it can't be sent. Before about an hour ago, when I tried to call someone, it just said it couldn't go through, but now it's saying crazy things like it can't connect to Verizon Wireless and I should contact my phone provider. Then there are the icons. Where usually just the notification icon pops up are now two new symbols. One of them is a tall, skinny triangle and the other is a box with a 1X in it. I can't click on them so I have no idea what they mean. Also, about half the time where the signal symbol is, instead of the regular symbol, it has the bars but also two arrows going in opposite directions."
I hope thats enough information for someone to help me (and her) out here. I rock a HTC Incredible so Windows Mobile is a whole other planet for me.

Have you tried to set it to connect to AT&T only? I've had it swap to T-Mobile (roaming) once, but that's because I forgot to set GSM Network selection to Manual.
(Slide all the way to the Settings Tab -> Wireless controls -> Phone -> Network)

It seems that you will need to set up a new modem connection for the phone to work on the AT&T network. She may have actually been using the US Cellular network all along, up until now and they have most likely caught on to it and she is now being blocked. You will have to set the handset up to use AT&T MediaNET by going into the settings and creating a new modem connection with AT&T's network name, proxy server and DNS settings for it to work right.
I know this because I have just changed one of my handsets over to SimpleMobile from AT&T and I had to set all of this up for my device to work on SimpleMobile's network.
Google around and you should be able to find the information you need to get this problem resolved, ie: network settings for MediaNET, internet and MMS.
Have fun, I know I sure did. lol

Here's some information I got straight from the HTC support site, hopefully they will get you started in the right direction but it does look as though you/she will have to contact AT&T support to get the internet set up since the MediaNET settings are hard set and non-editable. I was going to get them for you from my device but it will not even let me open the settings up to look at them.
What are the Data Network settings for my device using the AT&T Network?
The GPRS settings can be found by going to Start > Settings > Connections > Connections and then Manage my Existing Connections.
The AT&T MEdia Net settings cannot be edited.
For further assistance, contact AT&T.
What are the MMS Settings for my device using the AT&T Network?
The MMS Settings can be accessed on the device by going to Messages Tab>All Messages>Menu>MMS Options>Servers Tab. Tap on AT&T MMS or select New. Server Name: AT&T MMS
Gateway: wireless.cingular.com
Port Number: 80
Server address: http://mmsc.cingular.com
Connect via MEdia Net
Send Limit: 600K

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.

Mine should be in on Tuesday. Think we might have the wrong APN's??

Have you checked the APN settings?

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.

I agree, the settings aren't working for me either in Orange County, CA

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.

I agree but just thought I could push a bit more since I'm only hitting 6mbps. Thanks for the info though!

Trouble with sending MMS, and questions on setting up T-Mobile SIM card with G3

Hello all. Not sure if this is the right place to ask this, but no where else has come close to helping me find an answer to my questions.
----
Wow, that's quite a wall of text below. I'll try to summarize my three questions here:
Why won't my phone send MMS? It receives and sends SMS (after some tweaking), and receives and sends calls
What network do I choose under the Network operators menu? (RAT : LTE, RAT : WCDMA, or RAT : GSM)
Why is my phone's menus seemingly different from the menus in every G3 guide I've seen?
----
I'm having quite a bit of trouble getting my Verizon LG G3 (VS985) to work with my T-Mobile SIM card. Specifically sending text messages. Until a short while ago, I couldn't send any text messages. After playing around in the settings a bit it seems I can now send SMS, but not MMS. I can receive both SMS and MMS, I can receive and send calls, and I can use my data to browse the Internet. I'm utterly confused on how this phone is supposed to be setup and why it isn't working. While in my settings I turned data roaming on, but I tested sending a message after temporarily turning roaming off and it still sent. My APN settings should all be correct (though I'm not sure if there's something special I should set my APN Type as - it's left as "not set" as specified on T-Mobile's documentation).
Another question I have is what network I should choose. When I go deep into the network settings (Settings>More...>Mobile networks>System select> LTE/GSM/UMTS settings>Network operators) and choose "Search networks" it comes up with three T-Mobile networks. They have the following "RAT"s:
RAT : LTE
RAT : WCDMA
RAT : GSM
I'm fairly certain I'm not looking for "WCDMA" but what do I choose between LTE and GSM? As far as my understanding of cellular networks go, my phone should be using a 4G LTE network, but the network (T-Mobile) is also a GSM network. That left me thoroughly confused. Will one of these make my phone work better than the other? Will one let me send MMS?
Questions about T-Mobile network setup and MMS not sending aside, there's one other thing that's bothering me. In almost every troubleshooting guide I've looked up or been walked through, the menus all seem different. I've got software version "VS98535B" (if that's useful for you guys) and Android Version 5.1.1, which I assume is the default or should at least have similar options. However I've encountered two situations where my phone didn't have any type of the option that someone or some guide was trying to show me - once when looking for "WiFi Calling" in my settings (it's not there - "Advanced Calling" is in its steed) and once when looking for some spam setting in my messaging app (also not there). Any thoughts on this? Why does it seem my LG G3 has different menus from every Internet guide's G3?
Sorry to ask so much, but any help will be greatly appreciated!

Okay, WCDMA is 3G or HSPA. That's okay to choose but you'll want to set it to GSM/UMTS/LTE and let it choose it's own network automatically. If it's not letting you send MMS changing the network manually will have no effect. The easy way around this is to change your default text/mms messenger program and that will fix it. Either install Google's messenger app or use one of your choosing that's not the one that was included with the OS.

How do you set a custom APN?

I just got a brand new unlocked HTC 10 today straight from HTC.com. My cellular carrier is Red Pocket Mobile - an AT&T MVNO.
I connected the phone to WiFi and applied the system update for Nougat. I'm trying to set my APN for Red Pocket and it's forcing me to pick a carrier from a list that doesn't include Red Pocket. I select AT&T to get passed this and it allows me to add my APN settings. It won't let me actually switch to that APN though. There's a lock icon next to the AT&T settings and it doesn't seem to want me to change.
I've never seen this behavior on an Android phone before. Is this something new for Nougat? Is there something simple I'm missing here?
Thank you for any assistance
PS: See the attached screenshot. Notice that there's no radio button for me to click on next to the APN I've entered.

The answer is you have to select "US Travel SIM" from the list of carriers for it to allow you to switch APNs. Of course I figure it out minutes after asking for help.. :silly:
In my defense, it's not real obvious.
EDIT: I am so confused. I selected US Travel and input all the APN data. It doesn't allow me to select it now. It allows me to when I don't fill it out entirely though.
EDIT 2: The instructions I have from Red Pocket instruct me to set APN Type to: Default,mms,supl It seems like putting this in disallows me from using the APN for some reason. I hope it'll work without this setting.

Question No Service Issue

My new Pixel 6 Pro keeps having NO SERVICE. Restart required to temporarily resolve. - Google Pixel Community

Had the same on my wife's P6. The connection would appear briefly, the call sometimes would go through but then connection lost and asked to switch off plane mode by the system. Tried 3 different sim cards, hard reset etc.
Filed a return and her new phone is working as it should now.

That sux, as mentioned an RMA may be needed...

Started happening to me when I updated to v37. It was fine until then. I'll probably flash the old radio image later on tonight.
Edit: nvm, the radio.img is the same between 36 and 37. It is odd that this just started happening in the last 24-48h.

Your wife is lucky.
I've read on the link i posted that a guy rma 3 time with the same issue ....

If someone figures out a fix, please let me know. I am getting desperate here.

Been eyeballing the device ...from LTE to No Service..back to H+ than picking up signal again rotating for about 4-10 mins
Now I'm testing out turning off adaptive connectivity under network and internet sitting inside my office now.

Fixed on my end.
Settings> Network and Internet> Setting bolt icon next to my mobile carrier (T-Mobile)> Access Point Name> Created my own with the same settings from my carrier (T-Mobile) but with "APN type" only having: default,supl,mms,DUN
The rest of the APN stuff seemed to break my mobile data.
Hope this works for others too.

Interesting. Did you contact T-Mobile or Google and asked about this?
This seems like the type of issue that should be easy to replicate.
I would suggest to contact Google either way, since your phone might have a hardware issue (partially defect antenna or whatever) and you need to sort this out, before you run out of warranty and get problems later down the road (fix not working anymore).

So do you mean go into SIM card network page where you can see APN volte etc....under APN and create a new APN but with the exact same setting from the carrier ?

This worked for me. Thanks bro!

I started by turning off 2G. Worked for about 3 or so days. Then the issue came back. So, I turned off WiFi calling because I read somewhere that it was causing issues. I haven't had the problem since. It's only been a few days though. FYI I'm on Verizon.
I'm pretty sure it's yet another bug on the long list of them on this phone..

Go into settings > Network and internet > Sims click your provider there scroll down to Preferred network type change to LTE. I figured this out on my wife's phone. You'll loose 5g but it'll get you by temporarily until you figure out a better solution.
