Poor coonection during landline calls

[Danno]

I have been having issues with calling landlines. I can usually hear the person on the other end but they can't hear me. This issue is only a calls to landlines problem as calling mobiles is always fine. 

This was happening on my previous sim and phone and I expected an upgrade to resolve the issue with a new sim card and new number, unfortunately the problem still occurs. 

I've called Three and they're unsure of the issue.

I have exactly the same issue. The Wi-Fi calling is off and I have the issue for a long time now. My device is Samsung S10 Lite and I have a sim-only contract. It us totally useless with any landline from anywhere in UK

I'm having exactly the same trouble, I have for a year now and tried everything,  three are not interested so I'm paying for a phone that's useless as I am unable to make any calls to landlines as they just cannot hear me, they say the line is crackling.  Did you ever get it resolved?  And if so, how?  Thanks

Hi @Tracy444,

It doesn't look like we've heard anything further from the Original Poster in the meantime. Probably the best place to start in figuring out this issue, is trying to narrow down if it's linked to the phone, SIM/account, or the network.

A few questions that might help with this:

• Does the issue seem to be in particular locations, or everywhere?
• Is the issue affecting one, some, or all landlines, do you know if all the numbers you've tested are on one provider such as BT or Virgin?
• Are you able to test and confirm if the same issue happens with your SIM inserted in another phone?
• Likewise, can you try a friend or family member's SIM in your phone to check if the same issue happens?
• Do you know if anyone else on Three is affected in your local area?

I appreciate you might not be able to test or confirm all of these, but any info from the above should help us narrow down the next steps.

Thanks,
Jonathan

Hi Jonathan,  thank you for replying. 

Appears to be quite a few people having the same issue. 

It's all landlines, I can hear them but they cannot hear me it just breaks up, cannot be my signal as it is great for calling mobiles, it's just landlines. 

I've had the sim card changed, I've knocked WiFi calling off, and my friend with the same handset had the exact same problem, appears to be the handset on 2 different S23 ultra,  though not sure about everyone else.

I have the same issue as the others and don't have WiFi calling enabled, full signal 5g, and it only affects landlines. 

I'm only calling businesses for this and given they can only hear every other word I say for the topic I'm calling to discuss, I'm not about to ask them what provider they use for their business... 

Help please, as this has been going on for many months now and multiple phones, sims, etc.

Im struggling to get help from them, I've been to the shop and they have changed sim card etc, they just say must be poor signal,  paying all this money for contract and phone is unusable to make phone calls,  I'm pleased it's not just me though, so doesn't doing like it's just the hanset

[Tracy444]

Hi Jonathan, it's affecting all landlines that I ring, business and personal,  I've tried a few things with three through their help and nothing works, I cannot use my mobile for any calls to any businesses or personal they all say they cannot hear me and it's a very bad line

I have looked at coverage and network checker and there are no reported issues. Only thing I haven't done it turn off wifi calling. I have made calls when not connected to WiFi when I'm out and it was still the same.
