My voice cutting in and out on Public phone calls to some people.

I live in Waterloo and have been on Public about 10 months and have had about 40% of people tell me my voice cuts in and out when speaking or some just say 'what?'. Some don't seem to have a problem. I have the same problem in downtown Ottawa and on the Bruce Peninsula. I have a Sonim XP8 8.1.0. I was warned that Public has lousy coverage, but my son-in-law who lives in small town Tillsonburg has no problem. Our son's carrier is Bell, he has trouble hearing about 40% of what I say when I'm on speakerphone, he hears most everything when I'm not on speakerphone but then I can barely hear him. I called Telus because the phone is from them and he said he could hear every word clearly.When I was with Fido, nobody complained about poor quality. I put my SIM card in another XP8 and an XP7 and same thing on speakerphone. I haven't tried swapping SIMs with another phone yet. Can anyone help me? As far as I know I don't have pixel3.

I tried both test numbers and they are identical in operation. The recording came out fine the instant reply was probably okay. Everything else seemed fine also. When I spoke with a salesman from Telus he had no problem hearing me. When I talk to my son whose carrier is Bell he has problems with hearing a ¼ to a ⅓ of my words being dropped.  In conclusion I would say that everything seemed to test okay by these phone numbers.


All the variables could means the problems might be at Public, your phone, Bell or his phone. If it's only your son, it's probably his end.

Both numbers go to the same server, hence why I suggested calling "one of two" numbers. 😉

 

Anyhow... maybe get your son to call and test as well?

 

A few more test calls at various times throughout the day might be good too...

My phone is a Sonim XP8 as mentioned in my original post..Yes the phone was supplied by Telus and that is who the warranty is through. Yes there are towers close by. I live in Waterloo which is in the region of Waterloo which has a population of about 700,000. I had the same problem when I was in downtown Ottawa. It does not seem to be a lack of towers

My son and I swapped SIM cards. He installed my public mobility card and I installed his Bell SIM card in my Sonim XP 8 cell phone. My son still had the same problem hearing me when I was on speaker phone. When I took my phone off of speakerphone my voice did not cut in and out. In conclusion, it does not seem to be a problem with my SIM card because my voice still cuts in anf out when I have his Bell SIM card in my xp8 and I have the speaker phone on. If I turn the speakerphone off my voice is not cut in and out. It would seem that there may be two problems. One problem seems to be the connection between public mobility and Bell and the other problem seems to be my microphone when I use speakerphone. Does anybody know if there are two separate microphones? One for normal talking and one for speaker phone?

My voice also cuts in and out when I talk to somebody on Wind mobile when I'm on speaker phone. So far in conversations with people on Telus I haven't had this problem.

I checked your phone specs. Your phone does have 3 microphones.  One at the bottom of the front side, back of the phone near camera.

Not sure whether your phone uses different microphones for different type of calling.

    I want to thank everybody who offered me help to solve the problem of my voice cutting in and out when using speakerphone on my Sonim XP8. Dunkman got me on the right track when he mentioned that I had 3 microphones that may be used for different types of calling.

    I called a techie at Sonim and after about 20 minutes of conversation he told me the same front mic is used for speakerphone and non speakerphone. I asked why if it's the same mic being used do my words get dropped on speakerphone but not dropped when speakerphone is off. He said it must be improper communication. Below is what we did and so far it seems to have worked. My son (Bell carrier) and I talked for about 15 minutes and he said only a word or two was lost in that time compared with about 25% being dropped earlier.

    The Sonim techie had me tap on the Settings gear, then scroll down to tap on Systems then tap on Reset Options, tap on Reset Wi-Fi, mobile & Bluetooth then tap on RESET SETTINGS (This worked for me!)

    The Sonim instructions say to do it differently, I have them listed below as an alternative way.

NETWORK SETTINGS RESET
1. From Notifications or Apps menu, tap on Settings (gear).
2. Select Wireless & Networks > More > Network settings reset.
3. Select RESET SETTINGS.
It resets all the network settings including Wi-Fi, Cellular data, Bluetooth, and NFC.

@Stefanm Wow, that was a lot of work trying to track down the problem. 
Great job @Dunkman

 

I guess you can close this post and solution solved.

@Stefanm 

Wow thanks for this....the bf has had a similar problem where the caller can here staticy mumbo jumbo when callin but the bf has no issues. Every other type of calling is fine. I'm going to look up if it works similarily for his samsung S6.

    I'm replying to this post after the problem has been solved because it may help others understand what swapping SIM cards accomplishes.

    When my son (Bell) and I (PM/Telus) swapped SIM cards he still said I was cutting in and out on speakerphone only.Since he now had my PM card and I had his Bell card and there was no change in the problem what this indicated is:

(1) This is not a SIM card problem nor is it a carrier problem

(2) Towers were illuminated earlier because I had problems in downtown Ottawa, Waterloo and many other places.

(3) The problem is on my end, probably my phone

(4) Because the problem occurred with Bell and Wind/Shaw but not with Telus, this indicated that it was not hardware related but must be in communicationing between carriers and it must be a problem on my end, with my phone and software related.

Conclusion:  It was then determined by my phone manufacturer that my system, network, mobile data settings needed to be reset or changed which solved the problem.

    One of the Red Herrings that was thrown in was that the Telus techie first put the blame on Bell because Telus and PM conversations were good. He said he would call back after 10 days and I should record information all information regarding the problem to help him out. The Sonim techie was suggesting towers, carriers, and diagnostic utilities. I kept pressing the Sonim guy, what do I do if this or that doesn't work and so he gave me a flow chart of alternatives so to speak and one of them worked.

     Persistence paid off, the techies want to help but they will take the easy way out if we let them. I hope this helps somebody.

Yes, this helped me eliminate my hardware as being the problem. Thank you for those phone numbers.
