Sky mobile and VOXI are not 'networks' you pillock.As usual the partial 'truth' from mottie...
NETWORKS themselves that are charging for roaming...
EE
Sky Mobile
Three
Vodaphone
VOXI
And they make up the majority of mobile users!
O2 is the only one out of the 'big four' to not charge.
Call them what you like, whatever 'network' you’re on, you can get a better deal on an MVNO using the same network infrastructure that DOES allow European roaming in your included package. They've tried to jump on the "we’ve got to charge you because of Brexit" bandwagon and have shot themselves in the foot. Not been noticed the last few years because of the lack of European travellers from the U.K. due to covid and transport problems but wait until travel gets back into full swing, they’ll all suddenly find that they can give free roaming.
Sorry for bringing disappointment to all you bitter remainers.
