i cant use my data. i can go online only if connected to WIFI and my plan includes data, i can recieve email, but cant send it,, i was able to install and update apps, but no longer can, when i click install at the play store, it just sits at please wait , picture messaging is also part of my plan, but i cant send picture text's'.i get the error message "cant send, will send when connected to server", then the text with the attachment just sits at "sending" until i delete it. i have the zte 826 . i've gone through all the settings and just cannot figure this out. s0 i've been paying fr services i am unable to use. culd this be a something my phone provider has to set? i tend t think all these issues are connected....any ideas? thanks!!!
