Anyone knows how to subscribe others on Insta on an Android phone？

I tried to subscribe this really hot guy on Instagram on my Huawei. But I just can't. And this is what I got.
I try to install. The Google Play APP, but I just can't use it. Is it because I'm in China？ Anyone knows how to fix this? Thank you so much

I just had a look and I could if I wanted to subscribe I could so possibly is because you are in China but also as the payment is done thru Google play you may want to check your logged into ur Google play, if you are then yes it's down to your location
