unlocked s4 on metro problems - Galaxy S 4 Q&A, Help & Troubleshooting

What's up everyone. Im new to xda and was hoping someone could help me out. I have a s4 unlocked that im using on metro pcs. I seem to be having problems with the 4g. Its always coming on and off and seems like I have to place a call to get it back up and running. And could be a stupid but I cant seem to get any 3g when I lose 4g. If I dont have 4g I have no internet what so ever And also when Im on wifi and then turn off wifi 4g will not turn back on untile I place a call and hang up. And thoughts are helpful.

G2 Data Connection

Has anyone been having issues with the G2 Data? This morning and another morning this week my data failed, I tried going into airplane mode then restarting the phone completely still no signal and no cell signal either. My friend has a hacked and unlocked iPhone and his is working fine so I know its not a network issue with the towers... As well another co-worker has a myTouch 3g with no reported issues. Thankfully I have a wifi signal here at work.

That unlocked iPhone your buddy is using is EDGE only, obviously. That's going to give a better connection inside. Try running 2G only mode next time you get that issue.
I bet it was just a brief network outage in your area. It happens sometimes.
Not brief if it's a network outage... my connection is still gone... both my friends have theirs and one is on a myTouch 3g...

I do have occasional data connectivity issues, however, not that severe. Just your (what seems to be) typical "arrow stuck in the up position" issue.

Sounds like you have a problem then. I haven't experienced that on my G2 yet. My N1 forever had data connectivity issues.
Are you using the new simcard that possibly came with your G2? I have no idea if that makes a difference, but just asking...
Call T-Mobile and see what's up. Maybe they can refresh you on the network.

Say "english" at the first prompt and "representative" at the next prompt to skip to a live person.
Good luck.
Thanks Sean.

Tmo has been having issues, there are several reports of this and all my demo phones are unable to get online(though regular signal is fine) I would call care to let them know you are having issues too, ask them to make a ticket and/or send an engineer

I had to exchange a couple until I got one with a solid 3G connection. Previous G2's had no connection or were in Edge 90% of the time.
Nothing wild here.
It seems to work as its supposed to.
Would love to see mine switch to 3G. Been on Edge 100% since I got it Tuesday. Advertised in a soled 3G area, but no luck. T-Mo CS politely told me I will love Edge. Will be switching to Sprint Epic if nothing changes in next few days.
Mine does that too. I have to restart it.
Wonder if the supposed OTA-vapor new radio will fix that.
I've been having data issues too, seems like it has to do with how my phone is held (HTC antennagate?) I hope the mythical OTA comes with a radio fix (if that is the cause) and/or a vorpal blade....

I have a ticket open with tmobile about my data issues.
I'll have my phone on the desk and it'll have 1 or 2 bars of H and then I'll pick it up and its goes to G then to E then to nothing. Its worse when I open the keyboard.
I love this phone so much I hope its just a software fix. Is the OTA going to have radio fixes?

Exact same problem here. It's so frustrating. I've already exchanged it once and spent an hour on the phone with tech support. If it keeps up, I don't know what I'm going to do.
I am not liking the data issues.... I love the phone besides.
Fixed with a soft reset but that has to change...
There are a bunch of us with signal issues. I live in Vegas where we have great HSPA+ coverage and Im still getting a lot of issues even with 3G, that I didnt have with my Nexus One.
Check out the thread on the T-Mobile Forums. (I cant post the link since Im new here )
My issues are simply the phone works one min then the next there is ZERO signal, if I dont move but restart the phone I have full signal again. Some times the signal comes back on its own then other times it doesnt and I have missed calls after the restart.
I bought my dad a G2 as well (upgraded him from his G1) for his birthday, and he is having similar issues. I went into my local t-mobile store and they replaced the sim card 2x now and that didnt help. What I did find that helps is that if you set it 2G mode the phones seems to work fine. This is a temp fix but its retarded that T-Mobile's fastest phone is being forced to run in 2G mode.
I hope someone on here can figure out the issue or t-mobile comes out with a OTA fix asap.
Wow, the rep just tried to tell me I live in an area that is only covered by edge. I asked why I've had 3g hooked on my phones for the past 2 years and why my girlfriends phone says 3g. She then said I was wrong and she didn't know why the last rep told me I was suppose to have 3g. She then directed me to the coverage map where I pointed out to her how wrong she was.
....and she's a PDA specialist.
What upset me was how she was trying to convince me I lived in an area where 3G was not available. Despite having had 3G at this location for years. I told her I'd just call back tomorrow.
Edit: She must be on drugs, I see that I'm back on 3G.
The rep on the T-Mobile forums is asking you to PM them your info:
Hi everybody!
If you are experiencing this, we would like to hear from you. Please send me a PM with a few details. The location information requested is particularly important.
(Do not post your private information here in public.)
1. Describe your signal indicators when things are working well. For example, "Full signal with an H."
2. Describe your signal indicators when you are experiencing the issues in question (No signal, one bar, E, G, etc).
3. Provide a location where you are experiencing issues (city, state, zip code)
•Are you aware of other T-Mobile phones experiencing or not experiencing these issues at the same location?
•Are you indoors or outdoors when you are experiencing the issues in question?
4. Provide a location where things are working well, if available. (city, state, zip code)
5. The T-Mobile phone number in question.
Thank you!

I've had prevalent connection issues as well. For me, turning off Bluetooth and WiFi fixed the issues and I was able to get data via mobile network again. Bluetooth seems to be the main offender.
This exact thing used to happen with my N1, and this was fixed with rooted builds (Cyanogen/Enomther) from what I saw...... *grumble*
Sorry to resurrect such an old thread here, but I'm having data issues today in the Chicagoland area. Anyone else having problems?
I first thought it was an issue with the latest CM7 nightly I flashed last night, so this morning I reverted back to CM6.1.1 and still having problems with data. It shows I have 3G/H and strong voice signal, but no data is coming/going. When I reverted back to CM6.1.1 I did a complete wipe and then nandroid restore.
Thoughts?

Web browsing/data while on a call

I can usually browse the web and use data while I'm on a phone call.
Tonight I tried it and had no data connection until disconnecting the voice call. Can anyone who has not installed the OTA verify that it is still working? Or anyone with the OTA? Maybe I'm just crazy and am remembering something that didn't happen? No, I'm sure I could do both before.
I would hate to lose it this feature.

Works for me.. I've heard people say this happend before the update too, but I've never had any issues with it. Best thing to do is call tmobile to help you. It might have something to do with a weak signal, or not enough signal to handle both at the same time.
Have you tried using wifi calling and then browse the web through your wifi? That would prove it was somehow related to network signal.

My net won't work on Edge during a call, and is kind of laggy on 3G.
Sent from my T-Mobile G(dos)
U can only use data and voice with 3g/4g.
Edge uses the same stream as voice so you cant do both on edga data.
But I always use data and voice, mainly when looking up addresses or phone numbers
Sent from my T-Mobile G2 using XDA App
So maybe it was because I was on an Edge only network at the time of the phone call? I'll have to experiment more. To tell the truth I hardly make any phone calls with my cell phone.
This was all during a 35 minute trip across town so it's hard to believe it's on Edge the entire time since I have really good H access around town.
I'll call T-Mobile soon if it doesn't fix itself.
I've also been using a SIM that came with my Sidekick which was two phones ago. Going to also ask them if I am on the best web plan.
Thanks for the help.

I have noticed this problem on my HD2 for a while now. I am sitting on a nice 3G signal and the moment a voice call connects, my data connection dies. it does eventually drop to Edge or GPRS but bounces back the instant I'm off my call. it's really consistent as in the moment I connect, it goes.
I've seen this behavior on both my Windows and Android builds on my HD2.
I'm starting to think this is either a hardware issue or perhaps a greater T-Mobile one.
Any thoughts?

it usally takes about 30 sec for me to recover data on my phone sometime on 3g even on my tp2
I'm pretty sure now it was because I was on Edge. I've been able to use web while talking just fine recently.

3G no longer working

Hey guys, been up all night and lost several hours of sleep already. I thought someone here might have some insight that can help me.
I have been running CM10.2, decided to go back to a Stock ROM today to update PRL + Profile (Not sure why, just thought I might need it to get connected to new LTE towers in Sacramento).
When booting the MF9 based rom it was asking to do the 'Sprint Hands Free Activation'. It doesn't succeed unless I connect to WiFi. But even if it does succeed, I can't seem to get internet through 3G. After activating I can call phones / text, the 3G icon shows, but no websites work...
On a CM10.2 rom calls and text also work, 3G shows a signal, but no websites work over 3G.
I tried ##72786#, it just forces another 'Sprint Hands Free Activation' with the same symptoms. I tried an Odin of MF9 but it did the same exact thing.
Please help, I can't survive through work without the ability to call/text people. Thanks!
Weird I can successfully ping google.com. So ICMP is getting through, but possibly not UDP/TCP... I am really confused what's going on. There might be a small possibility this is on Sprint's end, but I doubt it.
Wow.. I wasted a whole night on something that is probably Sprint's fault..

[Q] LG G2 Noob here.

hello everyone. i just recently purchased a vzw LG G2 and was wanting to use it with cricket. I know there are many threads and posts about this but after 2 weeks of searching and literally trying everything i figured it was time to throw in the towel and post my situation. So as stated above i bought a LG G2 VS980 about 2 weeks ago and i currently have cricket service unlimted text/talk 20GB data. ok so ill list my issues and what i have tried to correct them
1. From the start i put my sim card in do the whole activiation thing over wifi and when my phone comes on it displays and H which i know is 3G service. I live in chula vista CA. my husbands phone recieves 4G LTE so i know we are in a good area. Now this is where it gets weird, when im connected to wifi the H turns to 3G and even 4G LTE will pop up randomly. My data works fine just slow of course and i cansend texts and calls but no MMS unless i use a 3rd party text app like Chomp or Textra.
2. The infamous sim card icon with a "?" . Are there any solutions to fix this? i have called LG tech support, cricket tech, took it into a cricket store, called VZW almost everything besides taking to a cell phone shop.
OK so i have tried every APN there is out there i have tried the ATT,AIO wireless, cricket,vzw, literally all of them and no diffrence besides recieving a MMS rarely. And yes i restarted my device after every APN input. My phone is currently set on global, when i try to switch to CDMA/LTE after 20-30 seconds it comes up with no network and says i must go back to global. i switch it to GSM and i have the GSM only or UMT only (maybe)? or GSM/UTMS. Not sure which one i put exactly but i put the GSM/UMTS mode and comes up the RAT networks here im confused and really didnt mess with it to much. but it will sometimes say E.
I am also wondering can i system update? i attempt to but it says failed. i kinda know that you cant update a device on any service besides its original one.
Now what are the harms of rooting and flashing? does my phone lose value? like i said im a NOOB here and this phone is literally brand new. I appreciate ANY help i get. If you have any questions PLEASE contact me asap. There is probably some info i forgot the add but i will be waiting for any kind folks to help me out

Dropping calls on Tmo

Hey guys,
I'm here because my Mom recently switched to Tmobile and while things do work, she is having an issue with dropped calls. The APNs are set correctly, she has data service, I've set the "network mode" to LTE/GSM so it shouldn't be trying to connect to the CDMA network. What could be causing this? She's about ready to buy a new phone, but I know there has to be a solution to this. The phone works, and granted it's her phone not mine so I can't say for sure exactly what's going on when it happens but she claims it happens ALL the time (7 dropped calls in a single conversation with someone) and I can't imagine why it would/should happen at all. What's the solution here? I'd like to keep her on stock firmware if possible, but if necessary I can either root and/or flash cyanogenmod.
If it were my phone I'd first root, try that, see how it goes, then try CM, see if that does it... but she's not going to put up with that back and forth and repeated wipes. She's just going to get annoyed and buy a new phone despite the one she has being just fine. It MUST be somewhere in the software. I'm not sure if it's trying to switch to CDMA before realizing it can't, or if maybe it has something to do with VoLTE trying to kick in and connect to Verizon.
I'm pretty proficient with this stuff (been modding my Nexus' for years) so I can follow directions pretty easily, but I do need a pointer in the right direction because I can't figure out what's going on with this custom Verizon crap... Thanks!
Probably a non-issue, but is her cell signal strength really low?
We recently did the same thing - moved Verizon S5 to T-Mobile, but my wife has had no dropped calls. Her signal actually is better on TMO than VZW (hence the switch). Our TMO rep set the APN and network mode like you mentioned, so that shouldn't be your issue.
Verizon VoLTE shouldn't be a problem either since you have a TMO SIM, its not even connection to the CDMA towers.
