That's the create Sina Mail account page that I'm seeing. I presume you can read Chinese, because Sina is Chinese only AFAIK.
She's had a SINA account for a long time. We're just trying to set it up on mobile device. Though she has it on her older device. I have input all the correct items that the mailbox asks for, and it won't connect in order to create the mobile phone account. I appreciate your help and time!

"手机号码" (mobile phone number), which I think must be a Chinese (+86) one. Not sure if Sina has an international page. I've never made a Sina account myself. Do you have WeChat, because you can sign up with that.
When did your wife sign up? Because in China now, I think to register for any online service, you must verify and confirm a real phone number or some other ID. The law is can't be anonymous online now with Chinese internet services.
