Using build 15228 on my 950xl. A day after installing it i noticed my sim contacts have gone.

u are a bit vague. have to tried to use the sim in some other phone?
maybe u have deleted them with some cooamnd and did not realize?
maybe u can recover them if u have made a backup. associating ur phone with ur hotmail account is very usefull to backaup ur data
