Can't download new apps on Blu phone, why?

[AC Question]

can dowload new apps no Blu phone.

I bought a Blu Dash Jr android phone for my mother-in-law to have her first smart phone. We were hoping she could use it with WhatsApp and Skype to be able to contact us. But I cannot get any new apps to work on the phone.

The phone has a "download whatapp" app pre-loaded but it crashes whenever we try to download.

There is no Google Play Store app on the phone. When I try to download one I get the error message "this browser is not compatible. Please use the google play store app" - which I dont have!
