Mine registers, but no incoming texts and the dial back service won't work.. poss something to do with all the kerfuffle yesterday...
Are you on O2?. Was thinking along similar lines, in that maybe they had switched off roaming, but can't see the sense in that as my Madar works fine for calls to the UK.
Yeah have a dual sim phone running my o2 and almadar sims.. My family have been calling both of my numbers but neither are working. Local calls and texts are ok, but nothing international working.
