3g and AT&T problems - Huawei Mate 20 Pro Questions & Answers

So phone is not working because of 3g gone on AT &T.
All incoming calls go directly to voicemail. Outgoing calls take two clicks to enable.
I am roaming in US from Canada. My provider Rogers told me to switch network to T-Mobile. That works but the problem is network selection has one choice Automatic. When you turn off and go to networks then chose T-Mobile it works but the phone shortly after turns back on automatic and AT&T then comes back.
Anyone have a solution to this?

I have a similar problem. All incoming calls go straight to voicemail. Outgoing calls and data service is fine.
I am using ATnT and Redpocket in USA.
Spoke with technical people at redpocket and they gave me new APNs. With one APN I started getting incoming calls but no data. They also suggested that my phone is not compatible as they are shutting down 3g service, but it doesn't make sense as I can still make outgoing calls plus with a different APN I can get incoming calls too.

I don't understand the reasons why this phone will not work. Maybe it uses volte to make outgoing calls. When I first dial a number it just closes but when dialed a second time it connected fine.
Back in Canada and no problem here. When roaming in the US it worked fine on T-Mobile but the phone kept defaulting back to AT&T which is Rogers Canada primary network affiliate for roaming in US.
Phone works fine on T-Mobile but that will end end of this year when they drop 3G.
Am trying to get an answer from Huawei support but so far nothing.
Will post any info I get from them.

Unable to recieve calls while browsing

Is anyone having a problem where calls go straight to voicemail when data is in use?
This is a serious flaw if its by design!
I'm on o2 with the latest rooted rom. Not the custom modaco one.
Well I've just found out this is a feature of 2g rather than a phone problem. You can only take calls and browse if you have 3g signal.
Maybe on O2, but I get calls coming in no matter what I am doing on my Hero with a 2G signal.
I'm on Orange.
Same on my Nokia's too.
We only have 2G at home so I know its not a 2G / 3G thing (for me at least).
Perhaps I need some different APN settings. Could someone else on o2 UK confirm whether this is a problem or not? Also if you could post your apn details?
My apologies.
You are right and i am wrong.
If browsing on 2G the call is routed to voicemail. Even if you press Home and stop browsing, the call is routed to voicemail.
It seems that only until you have tried to make an outgoing call will it kill something and accept incoming calls again.
No wonder I keep getting missed call texts from Orange.
It would appear that if the Hero is doing anything on GPRS (Weather, Mail, RSS etc) it will not accept calls.
Thats pretty crap.
My old Nokia's were not affected like this I'm sure... maybe they were and I never noticed.
if you can open a Browser window while on a call it will tell you that there is no data connection or to use WiFi.
So is this a 'feature' of the Hero or the 2G network ?
From further investigation it seems to apply to all 2g networks. I've done a bit of googling and there are a few posts about the iphone and similar issues.
I wouldn't mind if I could get a 3g signal in most places. I really hope that radio firmware gets better. Seeing as I can get 3g on o2 in a different phone at home.
Sigh, oh well... looks like people need to learn to SMS me or actually leave a message
This also explains why my TomTom used to crap out whenever I was on the phone (Nokia) sometimes... when it worked I must have been in a 3G area.
it's both phone and network dependent.
many phones do this on 2G, as there is no 2G device in the world that i am aware of that will do voice AND data at the same time.
However, due to this limitation, many networks have set up their network to forcibly terminate a data connection when a call is waiting to be routed to that phone. I don't know if it is a command that is sent to the phone that the phone has to interpret and support, or if it is simply killed from the network end.
some network/phone combos do it, some dont. it just depends on the combination of the two i think.
similar things happen on HSDPA, yet you can see the same HTC phone get forced down from HSDPA to 3G on t-mobile to accept an incoming call, but do nothing and get a voicemail on Vodafone!
Thanks for the response rhedgehog. I think if nothing else its good that people are made aware, I had no idea!
I would be interested to know whether other networks disconnect the data on the hero in order to receive calls. It would also be interesting to know whether other android handsets do the same.
My data habits have now changed. No more exchange push email - only check every 15 mins.

Unable to receive calls on 3G plan.

Is anyone else experiencing this? I'm on a 3g plan for AT&T and am unable to receive calls from iPhone users. It rings and rings until it goes to voice mail without my phone ever going off.
I am able to make calls, but unable to receive them.
I changed my APN settings to my previous settings and still no dice.
lol
thats LTE network Welcome to LTE lol

[Q] Atrix 4G stops being able to dial or receive calls

I've tried MROM and Topsmarts now with the same results. After some time the phone stops being able to dial out nor does it ring when someone calls, everything else seems to work as I can surf the internet and sms seems to work. I never know when this happens until I try to place a call and it says dialing ....then after about 10sec I get the hangup notification. The Phone is a unlocked and rooted AT&T phone now on the T-Mobile network, anyone else having this issue? The network is set to GSM/WCDMA Preferred and the APN set itself to T-Mobile US "epc.tmobile.com".

qpst and cellular calling

After using QPST for my Dad's Inc4g it has 2 odd cellular problems.
#1
It can make outgoing calls for a few minutes.
But then it says that the “phone number is not active or invalid” (like it’s not activated).
Then the only call it can make is to 611 (data and wifi off), but it gives me his correct balance and minutes used (so it's still connected to his account).
Rebooting does not allow it to make outgoing calls either.
It's as if it's partially dropped off the verizon network somehow because turning the radio on and off again also doesn't work (airplane mode on/off).
And when another phone calls him it goes straight to his voicemail.
BUT….if another verizon phone calls he CAN receive that incoming call no problem.
*Then once he answers that incoming call, he can magically make an outgoing call again!
So can anyone tell me what I might need to change, to stop it from loosing the ability to make outgoing calls?
It’s brand new (NOT rooted or anything else).
The Preferred network is set to CDMA only.
Only changes have been through QPST, and switched to NV-Only mode so he doesn't have to use the sim card.
Also after QPST the roaming triangle popped up, but I have the 58012 PRL (isn’t this the latest for this phone)?
#2
If he starts to dial a number, but then immediately hangs up (accidental dial), his next call gets the "system busy" network error.
Then attempting to make a call after that gives the same error as above (requiring a verizon phone to call to get him back on the network).
Could someone try do this and see if they can repeat this error?
So to anyone who has used QPST with this phone, or flashed it to another carrier, do you have any change suggestions for either of these problems? Maybe changing something in EPST?
Thanks for your help.

lg v30 does not receive a call. voicemail notification after call I should have received

during an incoming call, the caller hears the ringtone 2x and goes to voicemail. my home network is working fine. With my old mobile everything works fine. this is from the lg v30 lgm v300L. I specify in France. already factory reset. and in the mobile network option. I cannot choose 3g or 4g the page contains only access point name. When I make a call it works but I can't use the internet.
I receive an LTe network, 5/5 bars, although perhaps slower than my old mobile.
I owned the mobile 2 weeks ago , i notified this issue cuz a amazon delivery crashed yesterday cuz deliver called me without success.
