Having trouble

Is it the $50 prepaid plan, also what phone do you have?

Yes and I have android 4g

Do I need to buy more data for my friend to use my Bluetooth bc it's not letting me click on hotspot tethering 

No wayyy the $50 ($65 without autopay) plan comes with 5GB of hotspot data, I would recommend calling or texting customer service because the hotspot feature may not have been added correctly. Now if you’re on the $40 plan ($50 without autopay) you have to pay $10 per 5GB for hotspot. Customer service would be able to help with both :D

Ah okay, a fix would be upgrading your plan, or by just asking for the $10 per 5GB hotspot feature to be added (be very careful though because 5GB runs out like nobodies business)
