Random dropping of calls
Unitysounduk So it's looking like a poor signal level where you are. You have looked at the phone and the sim and excluded problems with either of those - it just leaves the signal.
Has it been worse since 3G was turned off? More pressure on 4G and 5G signal?
It happens randomly it's been happening since the switch off of 3G since February 2024 when it happens I still have like 3 bars of reception
Unitysounduk What makes and models are the two phones you've tried? Are they definitely compatible with Smarty's 4G calling (which is not the same thing as them supporting 4G calling generally)?
Unitysounduk Well, there is no 'compatible' list, just an incompatible list, but I don't think it's comprehensive.
Ultimately, if these issues started when Three's 3G switch off started, and you seem to have decent signal strength where you are, and SIMs from other networks are not having an issue, it does point to incompatibility with Smarty's VoLTE probably being the issue.
Before the 3G switch-off, did your S23 used to drop down to 3G when you made or received calls?
