[Q] [Solved] APN settings USA AT&T GoPhone

Hi
I am currently in the US for holiday. Bought two prepaid att go phone cards already in Germany and activated them. The Data connection in my wifes SAMSUNG SIII mini (stock) works as it should.
In my HTC ONE SV I only get EDGE working. No matter which APN settings I use as soon as I switch on something else as GSM only in Network data plan.it disconnects completely from Mobile and states "Service not available"
My SV is unlocked and rooted and running with the Russian ROM
Any quick suggestion what can help,
Edit: I went to a AT&T shop here. They were very helpful but couldn't get it working. Tried more things and at one point all APN settings were gone. After that I tried for the first time the "Reset to default" and it loaded the ATT Phone settings.
After a restart everything works. I have here with H sign in taskbar a download of 5Mbps and upload of 1Mbps.
I attach the screenshots of the settings

Chile S3 question

Hello I am in Chile because of my job, now i remember rooting my phone , now i got a GSM sim down here i can make phone calls but not use the data ... why>?!?!?!?!!??!?!?

You need to edit your APNs
Try either:
1) Going into Mobile Networks and manually inputting your carrier's APNs
2) adding apn's via this method
3) Maybe try step A3 from here. If you decide to do steps B1-4, ignore any mention of Phone Info and use Settings/Mobile Networks/Mobile Networks Settings/Preferred Network Type to toggle Global (as you've probably already done)
I have absolutely no experience with any of this. I've read a good bit on this as I've been on this phone.

Ah ok thank you i will try to do that, thing is idk what is the apn for the carrier down here that i an using . i will def check out the site u gave me once i get home snice im always traveling i get limited internet on wifi

[Q] 3g issue

Hello there, i just got this phone 3 weeks ago and since i have wifi i didnt test the 3g conection before. i activated a data pack and i just realized that my 3g doesnt come on at all. the screen shows 4g left side of the signal strengh but it doesnt work at all. i got at&t version. i confirmed with my carrier and i did activate data, they even helped me to set up the apn but is still not working. can you helpe me? thanks!
PD: they said they couldnt have done more because they dont support that type of device

Does it say 4G or 4G LTE? The at&t icons are a bit different I'd you're not used to them.
4G = hspa
4G LTE = LTE
So if you're getting the 4G icon you are actually getting 3G hspa speeds.

If another carrier besides AT&T, you will need to find the APN settings for your carrier and manually enter it into Settings>Mobile network settings>Access point names. Select "New APN" and enter the correct settings for your manufacturer.
The 4G icon simply means a network is present, it doesn't mean you are connected to it.

thank you for helping people. whel actualy i wouldnt mind getting 3g network access, the point is that i dont have internet access at all. i called my carrier (Claro - El salvador) and they helped me to set up the apt but is still not working. i was wondering if there is something else i could try to fix this

nevermind, i finally fixed it

Please share the fix so the information is available for anyone who might have the same problem in the future.

sorry. well, first i did master reset, once done i set up an apn (carrier provides you with this info), then went to mobile network > network operators > select automatically. once the device found the "CLARO" network i turned data on and got internet service.

Thankyou, these threads live on long after we're finished with them so it's important to have the information readily available for future troubleshooters.

I'm guessing you either had not entered the APN info exactly correctly the first time. Or also, after entering the APN you actually have to select it as the "active" one on the list of APNs (making sure it has the colored dot next to it). Maybe it did need a factory reset, but this shouldn't be necessary just to change APN.
Happy you got it figured out.

[Q] Modifying APNs with 4.4.2 (NE1)

Hello,
I've been putting off asking the question as I thought that somebody else had to have gone through this already but I've had poor luck looking through the forum and Google hasn't been able to help.
I'll be traveling to Italy in the near future with my Verizon Samsung Galaxy S3 (Build KOT49H.I535VRUDNE1). I would like to pick up a TIN or WIND SIM while I'm there, primarily for data usage. From what I've read, once I install the 3rd party SIM, I'll need to update the APN settings to get data to work.
Stock, it looks like the APN settings are uneditable. I rooted the phone with towelroot (if only everything were so easy) and then checked the APN settings to see if I could add another network. No dice.
Poking around on the web, it looks like in the past, people have been able to work around this by downloading build prop editor and adding the following two lines:
ril.sales_code=LOL
ro.csc.sales_code=LOL
I gave this a shot and was surprised to see the APN menu gone when I went back into my network settings. Through trial and error, I determined that the inclusion of ro.csc.sale_code=LOL changes my Mobile Networks options from:
- Mobile Data
- Global Data Roaming Access
- Roaming
- Signal Strength
- Network Mode
- Access Point Names
- Network Operators
to:
- Mobile Data
- Data Roaming
- Network Mode (GSM is not an option in here)
- System Select
- Dial Up Networking
There is no option to modify APN settings there. Am I missing something silly? Did something change in KitKat 4.4.2 that has caused this approach to "unlocking" the APN settings to become invalid? Is everything really ok and I'll have access to the APN settings when I insert the italian carrier's SIM card?
I'm game for other approaches as well. At one point, I thought I saw an article that talked about setting up a pointer to the APN settings prior to updating the prop file but I haven't been able to relocate that.
Any suggestions would be appreciated.
Thanks!
Aaron

In the event somebody else is looking for the answer, I got my hands on a TIM sim card today, installed it in the phone and the APN menu reappeared and let me enter a new APN. Looks like the answer as of today for this phone is TowelRoot, SuperSU, BuildProp and install the 3rd party sim.
Take care,
Aaron

Data not working on verizon Note 5 (Using a GSM Sim card)

Hello everyone,
I am from Europe, France, Using a sim card from Free Mobile. When i was in the US last week, i bought a Verizon Note 5, i saw on WillMyphonework, that it has the necessary bands to work with my network provider, and i checked the bands myself. the problem is that when getting home and putting my french sim card in, i can see the 3G, H, LTE text next to the network bars, but it is greyed out and i don't have access to internet through mobile data.
Has anyone had the same problem before ? is there a way to correct that ?
By the way, i put the apn information of my network provider, so it is not that.

Solved,
for those who have the same problem, update the apn setting then REBOOT the phone.
