The hotspot on my BV9500 pro activates and my tablet connects fine but the phone doesnt transfer its internet connection. The Bluetooth tethering also barely works. It'll be ok for a few minutes then no more connection.

I already have factory reset my phone three times and had to setup my phone again three times... Do not tell me that will fix it.

Hi there! Unfortunately such issue is related to your carrier APN settings. It is a known issue also for Xiaomi phones. The only thing you can do about that is contacting your phone carrier to get APN settings compatible with Chinese phones.

If your service provider requires extra payment for tethering, it will not work, even though the WiFi Hotspot can connect. The data connection will not be shared.
