Radio issues

Is anyone else having radio issues with their G-pro? AT&T model here and have been having very obnoxious issues with this device. I'm familiar with the common issues of losing 3g or 4g data while in buildings and such and have always had issues with my phones while in buildings but this phone is by far the worst so far. I'm not sure if it is only a network issue or this specific phone but I can barely get it to send and receive sms inside my house. MMS, forget about it. Calls get dropped immediately when I try to make them at home, etc... Last night I was driving home and on a phone call. Over the course of the 3 hour drive I got dropped at least a dozen times. I've never had these issues with a phone. Any suggestions? Should I try to get a warranty replacement or is this normal?

Could it be your SIM card? I have only had my phone for a week and haven't had problems getting a signal. However, on my old Galaxy Note, I had a similar issue and the SIM was to blame. Have you tried turning your phone off, taking out the SIM and reinserting it to make sure it's in there fully? You could also try cleaning the contacts (the gold part on the back of the SIM).
BTW...was reading your signature and had to LOL at the part about the Nokia Lumia. I tried a Lumia and only made it a month before Android withdrawals set in--so I sold it to help pay for my OG Pro.

Haha, yeah. I liked a lot about the Windows phone but just couldn't stick with it. I'm Android through and through!!!
I'll give that a shot or maybe get into the store and get a new SIM card today. Thanks for the suggestion!

Anyone....anyone...? Bueller....Bueller...?
Swapped the SIM and didn't fix anything. Wondering if it is an issue with the phone itself.

Can't Access T-Mobile Network

Woke up this morning and have not been able to access the T-Mobile network. No changes have been made that should have impacted the ability to connect. Greatly apprecaite any help.

If you made no changes then it's either your phone or the TMO system.

Well first, obviously, did you try rebooting your phone? Push into Airplane Mode and back?
Second, how is it not connecting to the T-Mobile network? No data connections? Or voice calls? Not connecting to the network at all?
Did you check your APN?
Can't really offer help if there is no accurate description of the problem at hand.
And finally, if you can gain access to post on XDA, why not contact T-Mobile themselves? As I'm pretty sure they can help you far better than many of us here with this issue of network connectivity. :silly:
Just sayin'.

I have the same issue. After a few days of getting brand new phone the data connection is messed up
Thinking of returning and getting S5

Call tmobile and have them refresh you problem solved

I went back to T mobile store. They asked me to wait 3 days. Refresh didn't help

Call up 611 on the phone (if possible) and say "Clear Location", that automatically clears out your phone connections and details (not your personal data) and resets the connections with the towers/antennas. You might need to speak with a rep or tech support to get that request, but they always do it if asked.
If you can't use the phone in question, call from another phone using 1-877-453-1304 and just give them your T-Mobile phone number in question and request the same.
Clear Location updates where your phone is being used and has it renegotiate its protocols, handshakes and talk, it essentially has your phone act like when it first booted up out of the box and was activated with T-Mobile.
I don't understand how the T-Mobile store didn't just perform that request/task with you when you were there....

They did do that and it worked in the store. But problem resumed when i got home

I would try the Clear Location again, just to see if it would fix it, if it doesn't, I would ask for a device swap in store to see if it works and holds.
It might be your account provisioning, but it was working fine then didn't, so it's most likely on T-Mobile's side. You can wait it out and when and if it works again, call up and request a credit to your account for the loss of service.
It seems to be your data isn't working at all but voice is, so you can check your Mobile settings and see if the APN is set to fast.t-mobile.com with IPv6.

Im going back today and swap for new phone. Im not sure if it was always working. Sometimes it works and sometimes it doesn't
When i first got the phone i went straight home and used wifi. I only noticed it 3 days later when i was outside. It was after that, that I started monitoring the problem
I get the 4G icons but little data coming thru

Yeah, I would try a device swap and see if that corrects the issue, since it seems the data reset isn't.
BTW, the 4G icon is for 3G+ (HSPA), which is slower than the actual LTE speeds. If you get LTE speeds, the phone will display "4G LTE."

I just swapped the phone and new phone works as it should. In the store the TMo employee had a G3 and we compared Ookla Speedtest. Mine was definitely not working like his.
I hope this new phone won't have a problem. They only waive restocking once. I was ginna swap for S5 but decided to stick w G3 for the screen

That's good to hear that you finally got it to work fine.
Also, in regards to the restocking fee, it is waived if the device is defective. They should not be charging it when the device is broken, defective or not working as it should. The restocking fee is for those who just don't like their device and want to swap out for another one.
You might have to fight with them about it a bit, but no restocking fees on defective devices.

[Q] T-999 Won’t Dial or Receive Calls, Shows 4 Bars

Samsung Galaxy S3 (T-999) stock, not making or receiving calls. Has been getting worse over the last 6-8 weeks. Now phone is almost unusable. Shows 4 bars of signal.
Phone says dialing, but never connects, no ringing sound. Sometimes after power cycling can make two or three calls. Often does not get data connection, though even when shows 4g cannot access data services. When others call, they go to vox mail. No ring or notification on phone. No error message.
Have tried several trouble shooting steps: Have tried different network modes. Have tired manually selecting T-Mobile. Have booted into safe mode. Have cleared the cache. Have done factory reset. Have tried different know good T-Mobile SIM card, and finally I replaced the SIM & SD Card Reader Module.
Nothing has had any effect, can anyone suggest a next step?

Flash stock firmware and factory reset. If its still happening after that theres a good chance its hardware or network issues.

In case anyone has a similar situation- flashed the factory ROM as DocHoliday77 suggested, but that still didn't fix the problem.
Had to send it off to Samsung for repair, who diagnosed a corrupted ESN and replaced the system board, (or PBA in Samsung speak).
Cost was $70, which also added a new 1 year warranty on the phone, and the customer service was excellent.

I doubt they really replaced the board. Do you have a new IMEI/ESN number ?

It actually wouldn't surprise me tbh. Its a much simpler process to swap a motherboard than to fix the IMEI/ESN problems! (I've done both, many times!)
I'd imagine, just for customer service sake, they would swap the board for a refurb and send it back. Then they can take their time getting around to fixing the original one. Then it would be come the refurb and the cycle of life continues!

[Q] Drops off network suggestions? -Samsung Note 2 - Wind mobile SGH 889v

So for the past year or so I've seen instances where my phone shows 5 bars and data, however calls go to my voicemail. I find out when I do something with the phone that forces it to rejoin the network.
I've got a 3rd party number that my enterphone uses, that number rings both my wife's phone and my phone at the same time. However very often only her phone rings, both of us appear to have good signals.
It seems that my phone is falling off the network but not showing this fact. If I switch to and from airplane mode it seems to regain network, or if I try to make a call it will fail the first time but work afterwards.
Any suggestion? I already installed Cyanogen about a month back hoping that this would resolve the problem, however it didn't have any impact. Same problems as before...
I'm wondering if flashing the radio would help, if so which files should I use?
I actually gave up on this phone and ordered a oneplus one, however that one arrived completely broken so now I'm stuck with the note 2 until that RMA gets approved or I get frustrated and just buy another phone.
Thanks in advance.

4g connection issues with note 10+ 5g

This is going to be long but I want to make sure I give as much details as possible. I went to preorder a note 10+ 5g. Was going to do a trade in but right before I finished the order decided to go with the BOGO deal instead and add a friend to my account. I received both of the phones and had 4g issues. Most apps had trouble loading anything. If I waited with the app open eventually it would start loading things up but not all apps acted like this. They may hang some but worked ok. Speed tests showed I had a good signal. After talking with tech support on the phone and going to Verizon stores several times they still couldn't get things to act right. They switched sim and phone out in store. One of the store managers said my first order was pending and that 1 if not both of the phones I had were supposed to be in there warehouse and that I wasn't even supposed to have them. They told me the best thing to do was to return the phones and start over. They had trouble returning the phones since I wasn't even supposed to have them. What they had to do was to charge me the full amount of both phones to my account and the credit me the amount. They said after my billing cycle was over they would do it and once my account was back to normal then try to upgrade again (still ended up paying extra on my bill for that ). So I went into Verizon yesterday and did my upgrade and still had the same issue and if I wanted to return them again I'd have to pay the $50 restocking fee . So I called them AGAIN! They have a ticket out but I tried to see what I could figure out on my own. I downloaded a network switcher app and went to 3g and everything was slow but worked fine. Everything also works fine on wifi. One thing I noticed in the app when I ran a ping was that IPv4 connected but IPv6 failed. It said IPv6: fail (1). Anyone else having this issue or know what's going on or know a fix? This is very annoying!

A couple years back we had problems with my daughter not being able to send or receive text messages and after endless efforts on the phone and going to the phone store where they suggest a new phone we looked on her Verizon account and she had some restrictions on there somehow for sending text messages. Long story short look at your account with Verizon and look at every single little nitty-gritty detailed setting - there might be something on your phone line or both phone lines that disallow 4g? Have the store try a different SIM card - NOT ON YOUR ACCOUNT, BUT A DIFFERENT ACCOUNY - and if the 4G works fine on the phone with a different sim card with a different phone number and account then the problem is with the carrier account you have...

I went through everything and didn't see nothing. As soon as I returned the phones and went back to my note 8 without making changes to my account everything worked like it was supposed to again.

RE: 4G Connection Issues with Note 10+ 5G
Hello,
I had the same phone with the same issue and am on the phone with Verizon Wireless now. We found that the 5G version will not read the 4G signal like it is supposed for some reason. So if you are not in a 5G area the data will not work. I just switched to the non-5G version of the Note 10+. We found this out by switching my plan to one that did not have 5G attached and everything worked just fine until we switched it back to the plan with 5G attached.
