[Nexus 5 Q&A, Help & Troubleshooting] sneak:
I called and told them that the speeds are slow for downloading and streaming and they asked if I'd like to "add more megabytes to my phone". She was stuttering like crazy and having trouble completing her sentences. She was clearly reading from a guide and took long pauses between all her questions. This is why I hate speaking with providers :).

She asked when it started happening and I said this month. Then she asked if it's also slow when I access websites on my phone. I explained that it isn't visually slow but that it wouldn't make sense for a mobile website to load slow. Then she asked how long it's been happening, "2 weeks?" I explained about the entire month. She asked if I have an LG phone then I said yes. She asked how many apps or games I download per day, I said less than one and she asked "how long will it took you to complete those downloads?". I explained it depends on file size. She said "it also depends on the details that say that certain application [unclear] megabyte [unclear] megabyte so it will be easier to do that. Mhm, there. so is there any error message any time you try to download applications?" I said no.

She asked for my zip code to check the outage in my area. She said thanks for letting them know I'm concerned with "my issues" and that they are "reporting a case here" and "providing information to their support". They added 50MB of data allowance to my phone plan. She kept going back and forth between adding $10 credit and adding 50MB of data, then she said 500MB of data for $10. Then she started calling it "megabits". I checked, they added 500MB.

She transferred me to tech support and I explained the situation. She asked me if the problem is that the speed is slow and when did this start happening, despite arleady providing this information. It's like they have some kind of form to fill out and they don't listen and just select things from dropdown boxes or something. After confirming my account she also asked if I'm on the $45 monthly plan, shouldn't they already know this? What a waste of time.. She asked what type of phone I have next then asked if it's AT&T branded. Then she read off the APN settings I should use (lol she said forward-slash forward-slash). She said APN type should be "default,mms,supl,hipri". She called Bearer "barrier" and I asked about APN roaming protocol and MVNO type and she said they don't have that. After changing the APN type the speeds were still slow.

She said she's going to refresh their connection with my phone and asked me to power it off, then a moment later to power it on. It was still slow so she asked for my city, state, and ZIP code. She said the towers in my area are definitely not the problem. By this time I noticed that the APN settings reverted, and I found there's an option I have to select to save the APN after changing it so I went and added that again, and informed her. Did another power cycle. No change. She asked if I recently downloaded keyboard or messenger apps and if there's any liquid or physical damage and how old my SIM card is. Next I was asked how often I update the software on the phone.

She said she's creating a case and the NOC will take care of it. She said she's going to credit my account and understands the frustration. She asked for the Android version and about what date I remember it last working properly. That was a 57 minute phone call that resolved nothing :P But I did it!

Let's get started? :)

EDIT: Saw you replied while I was on the phone, going to try that out now.
