Hey I just signed up to PM a couple days ago. Like the Subject says I can't make or receive calls.

I'm using a galaxy s8.

The phone is detecting Public Mobile as the carrier on the top left. It's telling me I have full bars for the service.

I can make and receive texts. And I can use mobile internet just fine.

For calling when I try to call it'll hang on "calling" for about 10 seconds and then just close the call. When receiving calls it'll let me pick it up but then instantly hang up the second I answer.

I've tried doing the standard reboots after inserting the sim and trying the different connection types for the mobile network.

Any help getting this working would be greatly appreciated!

@Thom20

I'm a visual person so knowing the anatomy of the phone and being able to visualize where the components are for calling may trigger a hypothesis to the problem. We are all grasping at straws. I was hoping @sheytoon would weigh in but he doesn't seem to be around.

Did you drop your phone at some point? My mom dropped her Galaxy S10 and it wont make calls anymore. I ordered her new phone and it works fine, just swapped sim cards. You may just have an issue with your phone.

🤷‍♀️

@darlicious I haven't, but I'm not planning on doing a tear down of the phone to figure out the problem 😛 I feel like we've been pretty thorough so far. It's just a very uncommon issue I guess.

Or this one

But to what end?

@Thom20

Have you looked at the service manual?

So I got a disappointing response from the Mods. After escalating the ticket their higher up people determined that there aren't any problems... I have no idea what they were trying but whatever it was didn't do anything. So we're back to square one.

@Thom20

I'm hoping @sheytoon can brainstorm and help decipher the numbers for you and @Nezgar .

Just a little update, I tried the sim on an old HTC M8 calls work and such. I can't get cellmapper to reveal the 3G info on this phone either. Could it be due to the age of the ZTE and HTC phones? Compatibility with the app? Or maybe I just need to change the settings to something else in cellmapper?

Thom20 · ‎11-05-2020

@Nezgar Those reading were using the PM SIM card.

I'm having trouble getting the ZTE to use the 3G network.

It only has GMS/WCDMA/LTE auto, GMS/WCDMA auto, and WCDMA only as options and radio switcher is incompatible with the phone.

Even using WCDMA only it's still connecting to 4G and not showing any of the frequencies on cellmapper.

Nezgar · ‎11-05-2020

@Thom20- OK, cool - will be good just in case something the mods do helps....

So we can see in your S8 screenshots your HSPA connection is going over 850Mhz/Band 5. However, I can't see from the ZTE screenshots anything other than LTE mode (We don't really care about LTE for this 😀 )- can you try your PM SIM in the ZTE phone with 3G/HSPA only mode? At a minimum to seeit's also using Band 5 HSPA @850Mhz, or maybe Band 2 HSPA @1900Mhz... try to grab the screenshots during a call as well.

Thom20 · ‎11-05-2020

@darlicious I tried all the tty settings, no change.

@Nezgar I asked the mods about reseting the account and their reply was "There is no such thing as restarting the account but I know exactly what I need to do!" That was some time yesterday. They said they'd reply in 48hrs so I'm very curious what they're reply will be.

I have tried another PM SIM in the phone and it also had the same results. txt/data working, calls don't work. I'm not sure about the previous post about them not working. The PM sims I have all work in other phones just fine.

At the repair shop I got one of the guys to check with their own active sim cards, they had Telus and they worked in the S8 just fine, calls worked.

I can't confirm if the Virgin sim worked the same way. The plan I had with them technically didn't allow the S8 to be used cause I had a low cost plan. However when I inserted the card it did seem to function similarly to how the PM sim is. I can't test anymore cause that account is inactive.

Here are some tests with cellmapper:

On the Samsung. I actually got it to connect to 611 for like 15 seconds this time after a few tries.

And here is on the ZTE, no problems with the call connection.

Nezgar · ‎11-04-2020

OK @Thom20, I just reread this whole thread to review what's been tried.. 🙂

- Have moderators tried anything to "reset" your phone/account?

- Have you tried a new SIM? Maybe something your phone doesn't like about your particular SIM, which I admit is pretty darned unlikely... Plus the fact that You'd burn the cost of a SIM since the old one becomes trash... - You mentioned in a previous post that Public Mobile Sim cards weren't working at the repair shop you visited - was that with an active PM SIM other than your own?

- In a previous post, you mentioned that a Virgin SIM also doesn't work - This could be another useful piece of the puzzle.

Lastly, may I suggest installing this app: "CellMapper" - It shows the specific active cell site, frequency band, channels, etc. It might be interesting/useful to grab a couple screenshots from this app while your phone is "idle" and "in a call" or "ringing" in 3G-only mode. (In LTE mode, it should switch to 3G only for the call, then immediately flip back to LTE normally) It will reveal if your 3G connection is using either the 850 or 1900Mhz band at minimum... and then compare with another phone like your wife's ZTE phone....

@Thom20

Almost the same settings as my phone....i thought I had found the secret portal. But it does almost sound like it has to do with a hidden setting. Have you tried using TTY ?

Thom20 · ‎11-04-2020

@Nezgar Had to try a few times to get it to connect to 611 again, it kept not getting through at all for a while. Finally the time I got in it was connected for 2 seconds before it hung up but the call timer was indeed counting up. The earphone jack didn't seem to make a difference in the call. connection.

When I call my wife it sometimes rings. When she calls me sometimes my phone will ring but she doesn't hear anything on her end, and usually it'll disconnect her on it's own after a few rings if I leave it. When someone calls me and I don't pick up it doesn't go to voicemail.

@darlicious I was looking for that but it's not in the settings. Maybe s8+ has a different ui. Though I'm pretty sure we checked if the wifi calling was off with a third party app a while ago.
Here's the phone settings menu for me:

I can think all kinds of things... but knowing results of more tests will help troubleshoot... And more ideas of things to test that haven't seen yet may help with a direction... If calls to 611 connect and the seconds-counter shows running (even if it's not audible) thats one thing... (hence try bluetooth, 3.5mm headphones etc may be worth trying) - if calls anywhere else don't even "show" a connection thats something else, etc...

I assumed that's where _you_ were headed. I went back to the OP and it said calls were just stopping.

But a good idea to verify that the ear speaker, the speakerphone and the mic are in fact working nonetheless.

This is very interesting if you can call 611 and hear something!... Instead of bluetooth, if you have a plain headphone jack can you try plugging something into that 3.5mm jack and make a call to 611 again, and then elsewhere?

If you call another nearby phone, does that phone even ring? If so, when answered is there maybe audio in one direction, or nothing either way?

darlicious · ‎11-04-2020

@Thom20

I'm going back to the WiFi calling again ..... came across this....

darlicious · ‎11-04-2020

@Thom20

Dang it I was hoping it might bypass the problem....but you can make WiFi calls( thru an app) but can you make fongo calls using mobile data? Your incoming calls if unanswered go to voicemail?

Thom20 · ‎11-04-2020

@darlicious Like using a bluetooth headset for the call? Or is there actually a way to make calls using the bluetooth signal?

I've tried a bluetooth headset and it does connect via bluetooth but the calls don't go through.

Thom20 · ‎11-04-2020

@Anonymous Calling 611 does work kind of but it cuts in and out. Says something about an automatic payment but I can't hear the whole message.

The bars are normally around 4/5 and when I call they go to 5/5

darlicious · ‎11-04-2020

@Thom20

Have you tried making a call using bluetooth?

And your mobile networks? Can you call 611 (I can't remember 🙂 it's been so long)? Do you have full bars or a few? If you have a few bars then when you try to call, the bars would probably jump up. That indicates the phone switching from LTE to UMTS for the call. Which it's supposed to do.
