Apparently it can be the same for text messaging as well, 2g is more consistent than 4 or 5g (or at least4 and 5g suffer more often from not receiving text messages again according to some articles online)

The original LTE spec for 4G had data and they forgot voice!
The GSM 2G aund the 3G have native voice (not using data mode) and the SMS is piggybacked on the native management signaling.
The 4G was designed as IP only (Only a single data mode), so SMS is simulated over IP and all voice calls use VOIP.
The 5G is partly backoffice integration, partly higher band and big capacity for stadiums, racecourses and to replace WiFi points. It does almost nothing for most other aspects. Change over during a call to VOIP on WiFi is a supposed selling point of 5G, but was available on 3G, but operators never liked it and few implement as they lose revenue.
The 2G GSM only has 200 kHz channels, but the voice and SMS (and 14K to 245K data) is all more robust than 3G because it's CDMA, it sheds weaker connections as number of connections increase.
The regulators relaxed coverage & capacity rules in UK and most of EU (see regulatory capture) so most operators reduced numbers of masts to save money.
They'd rather increase capacity by more bands than more masts using the cellular principle.
It's a regulatory failure. If there was one wholesale "RAN" and all the operators were simply resellers (like Tesco is, or An Post in Ireland) the effective capacity would more than double.
The 3G was/is terrible, basically a 5MHz channel version of USA 1MHz CDMA, because US patent holders "broke" the spec. A backward step compared to European 2G GSM. A multi carrier version of GSM for 1800 & 2100 MHz whould have been superior. Qualcom had far too much input on 3G and 4G.
