[Q] Slow Overall Mobile Data (ATT) - Xperia Z2 Q&A, Help & Troubleshooting

First off, thanks in advanced for reading this and any helpful comments are appreciated. I got my Xperia Z2 back in July. It was the International Version. I came from the Samsung Galaxy S4. I got the the S4 through ATT and the Z2 is my first unlocked phone. Anyway, I took the SIM card from the S4 and I put it in the Xperia Z2. At the time I had no idea about APN's and such so I expected the mobile data to work right off the bat. When I realized it didn't work, I went to the ATT store and they put in the APN settings and the Mobile Data works but I've noticed, it's very slow. On both H+ full bars and LTE full bars I have less than 1mbps download and the upload is even worse. I don't know what to really do. I tried putting in the APN settings myself and I learned about the Internet Settings in the more setting of connections and had the phone get the settings automatically. But still, no matter where I am, my data speeds are slow. I recently put the SIM card back in the S4 and the speeds are fine on there. I already considered if it was my plan but my brother is on the same plan as I am (He has a Nexus 5) and his speeds were significantly faster than me when we were out. I apologize in advanced if I sound like an idiot or an amateur but this is new to me. So again thank you for reading my long story! And here's a link of the screenshot I took of my speeds at full LTE Speeds:

Telus Settings for Internet, MMS, and Tethering

Internet Data
Taken from many sources and is reliable

MMS Data
Here's the MMS settings that I'm currently using. I had to move what was stated as the proxy setting into the WAP fields. They are working perfectly for sending and receiving.
Tethering
For Telus, change the Internet APN settings, APN = isp.telus.com
Go to the Internet Sharing settings and turn internet sharing on.
After that I would suggest changing the internet APN settings back to sp.telus.com without turning off internet sharing. Mind you, this is sort of hit and miss at times. I haven't really found any reason for it to be acting like that. Here's a screenshot of the internet sharing app when I am able to get it going.
Hopefully this helps everyone out there that is having the same issues that I had. Even if you aren't with Telus you generally get the drift with how it works and where to put each value. Getting the setting values for your carrier shouldn't be very hard to do. Enjoy.

Which version is your phone? Mine is
45/2012
1232.2109.1242.1001
RM-820_nam_canada_200
and my settings screen says Cellular instead of Mobile Network. I've also been unable to get consistent LTE speeds. Had them for the beginning of last week and now I only get 3G and sometimes 4G. Thinking about doing a reset to hopefully sort it out.
EDIT: Figured it out... locale settings

[Q] Is there a way to get my VZW S4 GPS to work in Ireland (Europe)?

I am planning on hooking my S4 up to O2 or Vodafone when I get there with a Talk/SMS plan, but maybe no data.
Will this phone be able to lock in with GPS without having a data plan?
I realize I will need an app that has the maps cached on my phone, any reccommendations on which ones or if this is possible with Google Maps?
Thanks, guys.
Sygic. It is a paid app and costs a bit, though.
I could be wrong but I don't think you have to have a data plan to use GPS. Here's the reason behind my response:
My neighbor has been asking if he can use an unactivated iPhone as a speedometer in his 1930 Model A. At first, I said no, then researched and found mixed responses. So this morning I removed the sim from my S4 and drove to work with a speedometer app I had previously downloaded. To my suprise, it worked.

Try removing your sim card and navigating. That'd answer your question.

You do not need a data plan to use the standalone GPS functionality. If AGPS data is old it might take longer for a fix, but that's about it. It's the maps and software that you'd need to be cached/stored locally.
As proof, here is an amusing screenshot for you, and no, it's not a GPS glitch.
anyone have any experience with one of these free GPS apps?

Verizon S4 won't connect to mobile or data. Any suggestions.

I picked up a Verizon S4 off CL yesterday after calling Verizon to verify that it had a clean ESN. I buy/sell/trade a lot of phones so this was a common thing for me. Upon inserting my sim card, I received full 4G and about 4 bars of service. Soon after leaving, I dropped to 3G, then no service. I went through everything I know to do:
Reboot / toggle airplane mode
Remove battery and sim
Factory reset
Odin stock image
Changed network settings in "Testing" via ServiceMode Shortcut app
Replaced sim card (twice)
I even opened the phone to see if the antenna appeared broken or disconnected

I've confirmed the device isn't water damaged by the strips on the phone (and inside) and on the battery.
Verizon has confirmed multiple times that the ESN is clean so I honestly can't think of what is wrong. Every time I've replaced the sim card, it could never activate in this S4. Popping it in my other S4 allowed it to activate and function properly. The phone has no physical damage so I don't believe it's sustained any physical damage. GPS works like a charm.
I can only seem to get sporadic signal when driving. Once I had it long enough to dial #832 and confirm it was working. I then lost it immediately.
Of course the seller will no longer answer my calls/texts and Verizon says it's not warranted. Besides sending it to Samsung for repair, what do you guys recommend?

M8S - Massive data downloads from Google Play Services (XPOST from the HTC sub-forum)

Hi guys,
I hope someone here can help me figure out a solution to this problem. It seems that every time I switch on my data (4G, 3G, etc.) Google Play Services suddenly kicks into overdrive and downloads an insane amount of data for no reason that I can figure out.
My first indication this was happening was when my mobile operator turned off my data a few days after getting the phone because I had already hit my monthly limit (3GB)! I switched off my data until my new bill arrived and when I turned it back on again on the 14th of this month, it started happening again. I went into settings and selected "restrict background data" and this stopped it, but my phone wasn't working as I expected it, as I'm sure you can imagine. Over the previous weekend, I was staying at a B&B. I turned on data for an hour and unselected "restrict background data" so I could use the phone like normal. I left the phone down for that hour doing nothing before I remembered I left data on (the horror!) and discovered it downloaded a further 300-odd MB's in that time.
I've attached some screens for you to look at. This is a new phone, but this behavior is totally alien to me. Can anyone help?

RESOLVED:
Called HTC Support and they were as surprised as anyone would be. They reluctantly decided that the best, even though the most primative, form of action here would be Factory Reset.
It worked, so I'm glad I have my phone working as it should now.

Anyone get LTE working AT&T/tmobile

Just got my Tmobile variant unlocked and using on AT&T. Only getting 4G. I've seen users having the same issue. Has anyone got LTE working? I've tried numerous APN's from AT&T as well as other suggestions and still nothing. Thanks in advance for any help.
Yes I have lte working on cricket(att). I have attached some screen shots.

I have a T-Mobile phone as well, and I had a more complicated problem getting mine to work. First thing's first - make sure you have your phone properly activated at an AT&T retail store, which is to say you can't have hotswapped the SIM; it needs to be tied to your IMEI. If it still doesn't work, make sure you're using the nxtgenphone APN. If you still have no luck, maybe you have the same problem as me. On AT&T's end, for some bizarre reason, my IMEI got registered as one that could not support LTE, so my line didn't get provisioned for it. I kept calling back, but no one could figure out how to change my provisioning. Finally I got a rep who tried something out of the box. He generated a "dummy" IMEI number for me, one that would be seen on the system as one that supports LTE, and registered that to my line. Lo and behold, that did the trick. I called Technical Support for this (you can ask to be transfered to that department if you call AT&T), so you might have to go through that - the good news is, it was rather quick, and I didn't have to get a new SIM card for it.
