htc touch troubleshooting -- call issues EVDO to 1x coverage

can anyone help me with my htc touch issue? not sure where else to ask this
i recently started having issues with reception after having NO problems with the touch since it came out. i come home for the day and my phone shows the evdo icon, but people try to call me and my phone doesnt ring, but the caller goes straight to voicemail. then it goes to 1x and my calls/email sync are fine. in order to try and get around this i perform a soft reset. however, when the phone comes back up it goes back to evdo and tries to dial #777 and fails numerous times. i try to make phone calls for the first couple of minutes that the phone is on, and they immediately terminate before im able to connect. the phone then goes into 1x and i can get data and make phone calls.
it isnt necessarily a problem with evdo connectivity itself, as when im at work i can get phone calls and data with evdo.
i did a hard reset and the only thing i've installed is a touchpal keyboard, but the problem is still occurring.
i called sprint and did a prl update from my house, and the tech support person said im in an area where coverage shouldnt be an issue. even with the prl update, im still having a problem.
this is very frustrating because i am missing important calls from business contacts.

I cannot make calls with my G2x

This is my second G2x and both have exhibited the same behavior. It will dial a number, whether from the phonebook or the dialer itself, and the phone application will say that it is dialing. After 30 seconds or so, and no ringing on the other end of the line, the call ends itself.
I usually have to enable Airplane mode, then disable it, to be able to make a call. sometimes I have to go as far as rebooting the phone completely after which it may or may not work. Incoming calls fail as well so I am missing quite a few calls and texts...but thhe emails and other data messages come through.
Oddly, data works perfectly regardless of whether the phone is having problems calling. This happens in 2g as well as 4g. I have manually selected 2g and could not call and had the same trouble in WCDMA only mode. I thought it was related to Wifi calling but enabling that has no effect.
Any ideas? I am trying my other line to see if that SIM card is having trouble. I just have no other ideas at this point.

happened to me today too. I have had the phone since March 20th and I have too reboot to make it work. No idea what could it be.

I used to have this problem frequently on my MT3G. Since someone else is having this problem on a different phone, I would guess that it's something software related.

Alright, it is happening on both of my lines. It might be a program that I installed so I am loading them back on one at a time to see if can determine which it is. I am looking at either Google Voice or Beautiful Widgets as likely culprits at this time but there is not certainty. I have also avoided installing Facebook and Twitter. I am able to make calls right now. I will see if this keeps working for the next few hours...maybe through to my morning coffee. I really hope it is an application, something I can do without, because it would be pretty bad if it is the phone. My girl just ordered one of these as well since she likes mine so much.

Happened to me twice today, first in the AM and then again around 2200 central time. i recently started using setcpu so not sure if thats an issue or not. anyone find the app responsible?

Yes, it has happened to me too, usually after it is in standby or idle, and this is my second phone. But my second phone not happens as often as the first one. Reboot is the only way I can get it to work. I notice that the signal is very weak only 1 or 2 bars.

That is a very good point to mention...that it is almost always directly after bringing the phone out of standby. Mine just did it again.

Same problem here. I don't even know how many calls or txts I've missed since.

Had this issue with my N1 and I always chalked it up to cruddy radio and/or coverage. I've since had it on my g2x once or maybe twice I think (had g2x for 3 days now), but at least after it timed out I was able to try again and the call would go through. With my N1 it would never recover unless I toggled airplane mode or sometimes even needed to reboot.
I hope there are some improvements in this area, because bad radio was my biggest gripe with my N1, and i really want to love this phone!

[Q] T-mobile One S won't receive calls

Hey everyone, I just got my One S yesterday and found out last night that the incoming phone calls aren't coming through. I can receive and send text message and make outgoing calls. Any idea if this is a problem with the phone or maybe a t-mobile outage?

Why don't you call the store you got it from or call C.S you just got it so anything wrong with it could be handled with them. Have you tested it yourself calling from another phone?

I just realized that wifi calling works. I also just called t-Mobile and after 30 minutes of diagnostics they told me that there is a network outage for new activations. Since it took them so long to figure out there is a network outage, I think they are full of it.

Are you still having this issue?
My wife just emailed me saying she was trying to call me but the call wasn't going through.
I was immediately getting calls when I changed my SIM yesterday...

When I first turned the phone on and called to activate my new SIM, tmobile made a test phone call to my new phone and everything worked fine. But now that I think about it, I think wi-fi calling was active at the time. I haven't received any calls today so not sure if the issue is still there.

This happened to me when switching telco, I got a SMS from new operator with a date but no time when my number would be ported. On that day I could make calls and send SMS but not get any calls. Turns out my number had been ported to new telco without me realizing this (I was still using my old SIM since it seemed to work to me.) After changing to new SIM everything was fine. All of this was on a desire though so might not apply to you ofc

Update: The phone worked for 24 hours and now is back to not receiving phone calls. Anyone else experiencing these problems?

Sounds like you have a bad phone, call CS or take it back and demand a replacement.

Calls not coming through - possible solution
I had this problem when I first got it.
First under settings->call->Use Internet calling - make sure you select Only for Internet calls.
Now go to wifi and make sure you are connected to a Wi-Fi network - then click the More menu listed under Mobil Network (three dots). If you have wifi calling enabled, go to Wi-Fi Calling Settings->Connection Preferences and select Cellular Preferred - otherwise you won't be able to make calls when not near a Wi-Fi.
Hope this helps - it took me forever to track it down!

The problem is i can make calls, just can't receive them. I don't think it's the phone as when people call me it goes to an automated message saying i'm not on the network. Even my voicemail doesn't work.

Nexus 5 Drops Received and Made Calls

Hey guys,
I have a Nexus 5 running 5.1 stock with an LTE connection in La Paz, Bolivia. Most of the time when I make a call or receive a call, the call is dropped. I have observed that as soon I make the call (with full reception bars) the LTE legend switches to E and then 20 to 30 seconds later, the reception bar dissapears and then the call is dropped.
I was hoping that with 5.1 update the issue will be resolved but nothing has happened.
I have contacted my carrier several times and my APN settings are correct and they haven't been able to troubleshoot the problem with the connection.
I would truly appreciate any ideas that you might have to solve this issue!

Ok, so after looking at several threads in Google Support for the Nexus 5, I tested a solution in which you booted the phone in Safemode and voila, my phone would not drop any calls and LTE would work just fine.
The problem is that Safe Mode does not allow loading anything but the core applications, so I can't use the apps that I have installed.
At this point, I think I have a software problem in which an app or a process drops the calls.
Do any of you have any ideas on how to diagnose which app or process is creating the problem?
Thank you

Issue with "Dropped" Calls

I have a G8142 with the latest security patches/updates on AT&T.
I'm having a strange issue occur on probably one out of every two or three calls. After about 45-60 seconds of conversation, my mic will cut out. I can still hear the other person clearly. I can end the call (this is not instant - it hangs up for 3 to 5 seconds) and then call the person back and resume conversation normally.
A few notes:
It doesn't matter if I place the call or if I am called
The duration from beginning of call to cutting out fluctuates
My microphone diagnostic indicates it is working properly
The call does not seem to actually drop - it will go on for quite some time (with me able to hear the other person) until someone eventually hangs up
Calling the person back/being called back does not fix the issue (it can happen multiple times in a row with the same person/call sequence)
Signal strength is usually -80 or better
The phone functions flawlessly otherwise. There also don't seem to be any issues or drops with respect to the data connection, and SMS/MMS messages seem to get delivered immediately every time. The phone hasn't been dropped or exposed to any liquid. I have disabled some system apps (like Facebook), but none that seemingly have to do with making phone calls.
I have full bars most of the time. I force 3G+ on the phone, as the 4G+ (LTE) signal is weak in many areas. AFAIK that only affects data rates anyway.
It doesn't seem to happen as much if at all if I put the call in speaker mode. I have not used a bluetooth headset for calls to see if that fixes the issue.
Here's some things I've tried:
Rebooted the phone
Updated my IMEI with AT&T. I'm not sure if they actually did it (they stated it was "already changed") or if it makes a difference. My last phone was an unlocked Nexus 6p and did not have this issue. I did not get a new SIM for this phone.
Double-checked and redownloaded the APN settings.
I haven't tried voice calling through a third-party app, like hangouts or whatsapp, but I assume it would work just fine because it's being transmitted over data.
There is either a GSM/setting issue on my end, a settings issue on AT&T's end, or possibly a hardware issue (like a loose SIM, faulty mic, or bad antenna).
For now I'm at a loss, and any ideas would be greatly appreciated.
*** UPDATE ***
I've tried clearing the phone app cache and making sure that battery optimization is turned off for the app. I'll report back if this seems to fix it in case anyone is having a similar problem.
*** UPDATE 2 ***
That didn't work. Calls still drop intermittently. I've pretty much narrowed it down to a problem with the antenna, AT&T towers not particularly caring for the baseband firmware on this phone, or an issue with the dialer app. Performing calls over data (like Whatsapp/Hangouts/Duo) works flawlessly.
We'll see what happens if the phone app gets an update, or maybe after Sony releases the Oreo update.
For those US XZP users on AT&T or those that were considering buying this model, be aware this issue may affect you.
*** UPDATE 3 ***
Changing the mobile radio to 4G (preferred) instead of forcing 3G seems to have solved the problem.
