I'm dissapointed that 48 still doesn't allow to use 4G roaming and you can connect to 3G network only while roaming. Also in the UK the only network allowed is O2-UK and 3G connection only. While it's quite good in the Republic of Ireland, it has a very limited use abroad. Many foreign mobile operators are limiting and converting 3G coverage already and focusing only on a 4G and 5G so this is quite frustrating
