Q: Why does my data constantly switch? - Samsung Galaxy Nexus

I'm on att and my nexus constantly goes from h to e to 3g and all around. It pisses me off. I called att and had a case opened because my phone was on a 3g plan and they can't change it to a 4g hspa + plan because my device is unknown. Is anyone else on att and had this? What did you do?

The phone should always switch back to UMTS (3G) when the data connection is "idle", and only switch to HSPA+ (H) when data is actively transferring. This is a power-saving feature of GSM because UMTS has a much lower power draw than HSPA+. Your phone should not be switching down to EDGE unless you're in a bad coverage area (0-1 bars of 3G, for example).
As far as AT&T not provisioning the plan for HSPA+ "4G", how did you start the account? If it was started with any other non-LTE smartphone, you should be provisioned for HSPA+ already. AT&T does do some weird provisioning and uses APNs often to restrict speeds, but unless you were previously on an LTE plan you should be provisioned just fine for the full speeds.
If you're constantly switching between EDGE and 3G but you're in a good signal area, you may have problems with your SIM. It may be easiest to go into a store to get the SIM replaced, and talk to someone to make sure its provisioned properly for HSPA+. I really hate that AT&T messes with this stuff, it makes it hard to move around the SIM into different devices, a huge feature of being on a GSM carrier.

Try the scotch tape trick, put 1 layer of tape on the non contact side of sim card. There have been issues with sims being too thin by less than .5mm and not making good connection.
If that doesn't work, get a new sim from any att store, it's free.

Thanks so much for the help I'll head into a store and see what the issue really may be.

4g/3g data connection

It seems whenever I don't have a 4g data connection, I'm not getting any data connection. Anyone else have this problem? When I'm in builldings I never get a data connection. Even when I'm outside I rarely get data connection unless it's a 4g spot. I know someone with a GN and side by side, he gets a connection at work while I have gray bars. Is this prevelant among most of you all? I'm on Verizon if that makes a difference.
Yes, I have this issue as well when I am at work but only when I have wifi turned on. With wifi on I get no 4g connection inside the building and the phone won't drop down to 3g, just gives me gray bars and no data. Manually switching from LTE/CDMA to CDMA restores my 3g data connection. Turning wifi off enables the LTE data connection. I assume it's trying to use the building's wifi network that I am not authenticated to for some reason. It's quite annoying and seems to be draining my battery.
My 4g reception sucks. I am rather disappointed. I canceled my ATT account and paid the ETF to switch to verizon for the GN. I am in plano tx which is in the Verizon LTE area and i dont get any signal except in a few spots on the highway. I work in Richardson, which is also in the LTE area, and i dont even have 3g in the building. I dont have any signal when i go deeper into the building away from the windows. I am running stock 4.0.2. I hope this gets better. I am already regretting dropping ATT.

Strange. I have excellent 3G and 4G signal in buildings, coming from Sprint I had non-existent data everywhere, especially indoors.
Just as an fyi. I went to Verizon to try to get a new phone. They told me my sim card was bad. I got the phone on the first day and they said they had issues with the first sim cards with the nexus. My wifes has the same problem.
New sim card, NO MORE connection issues. Yeah! Anyone else who has this issue might try this. I am now getting 3g and even 4g connections inside now.
ill go to the verizon store after work and switch sims. Just got it on 1/1. Ill go to a different verizon store to make sure its not a bad batch lol.
Wasnt the SIM card. Still getting crappy signal strength. I am going today and replacing the phone. If that doesnt work, i am going back to ATT skyrocket...

In my office I get very weak to no 4G signal, so that the phone is constantly switching from weak 4G down to 3G and causing connection disruptions. I usually just disable LTE and use CDMA only mode to fix this. I have heard that a LTE signal should penetrate inside of buildings better, but apparently my workplace is almost impenetrable. We have a Verizon 3G repeater in the office or I would get no usable signal at all.
Spencer, what kind of speeds are you getting with LTE in the Columbia area? It seems like I got better speeds when I had my Rezound than I'm getting with my Galaxy Nexus.

I've had the exact opposite experience in Dallas. I switched from AT&T a year ago. I couldn't even make calls in my house. (I live in Lakewood) I had to go upstairs or outside. As far as data goes even on just 3G the Verizon speeds are much faster. I've done quite a few AT&T vs Verizon 3G side by side tests and Verzion has won every time. 4G is just a bonus for me. When I get a 4G signal there is no comparison. My coworker and I did a speed test on Tuesday at DFW. His iPhone 4s on AT&T vs my Gnex. I was getting 10-15 mbits down and he was getting like 2-3
3G Data
I am having the same exact problem. I thought it was related to airplane mode, I have it turning on at midnight and off at 6am. In the morning, if there is no Wifi and the phone is in 3G, I can't get data. Restarting gets data back, but I'm looking for a more elegant solution than that.
I'm having HUGE data issues, see:

Ubergizmo on Nokia Lumia 900 4G/3G/Edge switch

Has anyone else found the following web site with instructions on setting up a 4G/3G/Edge switch on the Web
(Do a search to find the link)
I tired it and was able to get the switch, but I have not been able to try it on 4G(LTE) yet as I do not have LTE reception where I live and only have 3G (the phone says 4G, but I know it is 3G+) but will try it at work tomorrow where I can actually get LTE.
But one thing I noticed is that I cannot get EDGE service where I live. I heard that AT&T wanted to get rid of 2G (EDGE). Have they done that already?
Hre is the link:

Im not sure what you mean about trying it on 4G... the only choices are 4G (LTE) 3G or edge so you get one of the 3.
In my LTE market when I choose 4G I get LTE.

On AT&T, there are 4 types of data. 2G/EDGE, 3G, "4G"/3G+/HSPA+ and LTE.
We all know about 2g and 3g, but many people like you don't know about the difference between "4g" and LTE.
This whole thing was started by T-Mobile, because this was the early days of LTE, and Sprint was advertising it's WiMax network as 4G, T-Mobile decided to use a technology called HSPA+ and brand it as 4G. Initially, AT&T scolded T-Mobile for this move, but as soon as it was decided HSPA+ could be considered 4G, AT&T rapidly built up a network of this, almost as large as their 3G network.
HSPA+ is basically a faster version of 3G, hence why it's often called 3G+. However, AT&T tries to advertise it as 4G so they can boast they have the largest 4G network, even though Verizon leads the charge with the most LTE sites. HSPA+ is a bit faster than 3G, but doesn't hold a candle to LTE. However, it does have it advantages, such as being compatible on the iPhone 4S, and unlike Verizon, on AT&T, if you loose LTE coverage, you can fall back on HSPA+, where as on Verizon you fall back on their CDMA network (Which is still slower than AT&T's GSM network).
So over all it's good and leads to faster overall experience, unless of course you're in LTE coverage 24/7, then it doesn't matter that much. My (and others) only problem with this is AT&T branding it as 4G, which tricks consumers.
These days, both AT&T and T-Mobile branded devices display "4G" for *any* UMTS connectivity, instead of 3G/H.
It's lame.
My 900 has this switch in the settings without the need for any hacks
you hit #data# and then hit the ... button at the bottom and set up the toggle between speeds. Then restart the device, go under settings>cellular> select data speed.
With this device's data speed selection, 2G= edge, 3g= HSPA+/UTMS, 4G= LTE. Eventhough ATT modified the registry so that UTMS shows 4G at the top of the device, when you select 3G in the speed selection, you are only making the phone connect to HSPA+/UTMS

Hey, they stole my article that I originally posted on Mobility Digest. (www.mobilitydigest.com). They even took my screen shot. I purposely took that shot when my phone was showing "G". Oh well. Btw, it does work.

Switched to Straight Talk, using TMO SIM, only get EDGE, can I get better data?

Hey guys, I asked awhile back about switching to ST and I've done it. I finally got data working by using a TMO SIM, but I can only get EDGE, no more, no less. Even in relatively large cities in my area that have TMO towers, I only get EDGE. My question is, is there anything I can do to get better data?
I have Verizon LG G4 on Straight Talk Verizon Towers and everything works great! Not sure what your issue is. Only issue I see is when I make a phone call, it drops to 1x always

That's because you're not using Advanced Calling (VoLTE). On Verizon's network, calls always drop to 1X unless you're using Advanced Calling. In the past, most Verizon phones didn't indicate this. They would continue to show whatever data connection the phone had (3G, 4G) even though the call was being done over 1X. Several recent Verizon devices have been more honest about which networks are actually in use, including the G4.
So, what you're experiencing isn't an issue. It's what should be happening.

That's because you're using a Verizon ST SIM, the OP is using a T-Mobile ST SIM. Also, you need to enable Advanced Calling on your account and your phone to use voice and data at the same time over LTE.
To the OP, I have the same problem. When I put my T-Mobile SIM in my VS986 I only get 2G at home, while LTE only works in the older LTE sites that are using band 4 primarily. Most 2G > LTE sites are using band 2, which according to the Verizon spec page this phone supports, but it must not be active as it doesn't work. I've been looking at ways to enable band 2 without any success yet.
To the OP, you added the APN configs for Straight Talk T-Mobile, correct?

I just opened a thread asking about VS986 wcdma bands availability. I was reading LG specs and they say this phone has no 3g, just 2g and LTE. Reading in many other web pages they say this phone has all 4 wcdma bands available. Maybe they are software locked?
I think, I made a mistake buying this phone to be used in a GSM network. Have you checked with Verizon/Tmo rep?

What are your LTE speeds like? I thought about making the switch but then I read that Verizon limits LTE speeds on ST to 5MBPS...Is that true? As it is my 3g+ speeds end up being faster than that most of the time.

I'm getting better than 5Mbps, but definitely shaped/limited bandwidth. If you actually use 10Mbps+ regularly, keep shopping.

Using this phone on AT&T, can't get 3g data

I cancelled service with verizon, and put my att sim card into this phone.
But the best data connect I can get is edge (2g). I don't expect this phone to get ATT's lte network, but is there a way to get 3g data connection? Edge is just too slow.
Also, is voice quality tied with network type? I feel the voice quality was worse in comparison to my ATT phone. But the signal shows full bars.
Thanks.
Edit: today it magically worked. I don't know what happened, as I didn't do anything to it. It is now running on HSPA+, with very nice speed.

Yes, after setting it up I was able to connect to EDGE. But that is only 2g speed. I read online that many people were able to connect to 3g (HSPA+).
Some of them mentioned reporting IMEI to ATT. Would this matter?

Try to call ATT and make sure they provision your SIM card with 4G LTE service. (you might need an IMEI that is compatible with ATT LTE for them to activate that option)

Compatible Non-Verizon carriers?

I'm thinking about taking my Verizon HTC One M9 to another MNVO that leases Verizon space. Has anyone had any luck doing this? I'm specifically looking at carriers like Straight Talk or Total Wireless that claim to specifically sublease off Verizon, but their sites won't tell me exactly what kind of service I can expect to get if I bring my phone over. For instance, Ting tells me that my phone would only run on their 2G GSM network, so that wouldn't be worth it.
I've also tried willmyphonework.net to test the Verizon HTC One M9 against several carriers, but I haven't found one yet in my area that seems to be fully compatible. Straight Talk shows a yellow check mark on the 3G and 4G LTE networks, indicating that it might work, Total Wireless shows a blue check on 3G but an X on LTE, and Cricket has a blue on 3G but a yellow on LTE.
Anyone have any experience moving to a MNVO with this phone? Who did you end up using?

I use mine on StraightTalk. I live around the Birmingham, AL area and if I'm in a Verizon LTE service area, I get LTE on StraightTalk as well. 3G also works when not around LTE, but anything below 3G is questionable. Some areas I'll see 1X as my service (not sure what exactly it is but I assume 2G?) and obviously data doesn't work. It's not that it's too slow, it just doesn't work at all. Also, with StraightTalk, although you are supposed to get unlimited data, you only get 5GB of high speed data per month, and after that it drops you down to 2G. I haven't tried any other phone, but I know the M9, once you hit 5GB, your data is pretty much shut off. I've tried different APN settings to force it to use 2G with no luck. It just shows connected to 4G/LTE or 3G. I can't force it to use 1X no matter where I am unless that's the only connection available.
I would assume Net10 would work as well seeing as how Net10 and StraightTalk are the same thing.
