I have a duel-sim phone. When connected using the O2 sim I can't access
certain websites (e.g. theguardian.co.uk and theverge.com)The error I
get in Chrome is: DNS_PROBE_FINISHED_NXDOMAINWhen I use my EE sim, I
don't have this problem.Any ideas?樂
So far I've found three sites that are inaccessible over
4G:theguardian.comreddit.comtheverge.comAny more? p.s. I've just been
told by O2 Support that there's a problem with the local mast.
