Just wondering why I sometimes get this message when calling 028xxxx number from my vodafone mobile .. it occurs at random it seems .. ie about once a week .. lasts for a day then comes right .. at various parts of the country .. not area specific. rest of time calls go through perfect.. Am I correct in assuming it is a Vodafone issue .. when I phone the number from a telecom mobile it is ok ... unusual as this is a regular and apparently random occurance. Any sggestions John R?
