the 2nd link you suggested worked a treat so thankful for your help. i was getting to the stage where i thought I'd fixed it🫣🫣 just to go into contacts to find no names just numbers. i took my time to follow 2nd link and it worked a treat everything names and numbers all returned many many thanks for your help/suggestions had a stress free rest of the evening x many thanks
