Hi all, I have just swapped the wife out of her old Mi phone and into a new Samsung Galaxy S21FE supplied by Spark. I just removed the SIM from the old, installed in the new, changed no settings and off she went.

However the call stability is terrible. It constantly cuts in and out on calls, and generally drops out. On my phone it says "call failed". It is really bad.

Worst of all, yours truly is copping it!

Any ideas why this would be happening? We generally get 3-4 bars at home. It says it is on 4G/LTE. I did change a the preferred network from auto 2G/3G/4G/LTE to 2G/3G/4G/5G/LTE just to see if that made any difference but seems about the same.

Cheers for any advice.

No, nothing updated yet. So... recommend a full system software update?

If the above advice doesn't help, try disabling VoLTE for a spell and see if things improve. LoLTE is still a little flaky in N.Z.

Thanks for the replies - there was an update waiting so have installed it. We'll see how that goes then look at disabling VoLTE if problems persist.

VoLTE in NZ is fine. Some handsets can have a "flaky" VoLTE implementation though.

Take the phone back to where you purchased it and tell them it's not working properly. They should either help fix the problem or replace the phone. My wife has an S22 and hasn't reported any issues, I imagine it's much the same as the S21

my Note 20 has this exact issue with volte with sim 1 but not sim 2

however my S22 sometimes cannot receive calls on Sim 2 and sometimes cannot dial on Sim 2 - not volte issue (or is it lol)

Just super busy and no time to take it in to Spark at the moment. There doesn't seem to be any option under "mobile" to switch off either VoLTE or wifi calling for that matter. Maybe a custom Spark thing?

Just noticed the sim is in slot 2. Will swap. Clutching at straws.

I have mentioned on a couple of other threads here that we had this exact issue with Spark and S21FE (and a couple of other phones) for a year. Happy spark customers for many years. All was good until late 2021 for us.

It was looked at by a range of spark staff including members who also are active on Geekzone. But ultimately was never resolved and after nearly a year ported to Vodafone (it was affecting the ability to do my job), without anymore issues.

I had constant dropped calls and/or calls with broken audio or calls that would just fail to setup or incoming calls that would go directly to voicemail.

It was not everywhere which was odd. Spark took call traces and could see packet loss on the uplink and an issue with a tower(s?) In our area.

I had to disable VoLTE but that option was taken away with a software update. I found using the app "Samsung band selection" from the app store I could turn it off via a hidden menu. That was all well and good until I was in a RCG/LTE only area.
