Cant download apps on my new huawei

I just bought my new huawei model H30-U10 I have synchronized my gmail account and whenever I try to download any app, the download bar keeps loading forever and doesn't even throw any error I am not using SD card because its internal memory is 8gb already My time and date are ok I am not using sim card, could this be issue? The google playstore version is 4.6.17 and I am sure its not the latest one and I cant even update playstore through playstore> settings> build version> update
