It can be something wrong with the power button

There is four simple step to format . just follow it. remember if ur phone memory have important data so u should be aware that i will erase ur data.but there is no other methods so.. 1- Power down your device. Before you begin the reset procedure, you will need to completely power your device off. If it is frozen, you can pull the battery out to turn it off. 2- Press and hold the recovery buttons. The buttons vary from device to device, so you may need to look up the instructions for your particular phone. You will need to press and hold the buttons for a few seconds. Some of the more common button combinations include:

• Volume Up + Home + Power
• Volume Down + Power
• Home + Power
• If none of the above work, do a web search for your phone's model plus "recovery mode".

HAVE YOU BEEN INTO THE PHONES SETTINGS AND SEEN IF WI-FI IS TURNED ON,

call your cell phone provider for help using a good phone,

The sim card has to be registered along with adding service.

I remember reading somewhere about an issue with so called off brand phones(Non-Flagship)... as im in the same boat(Using Cubot Brand) and talking with my service provider today. they stated my phone isnt on the list or compatable with the at&t network anymore(atleast the calling part of it) you should still be able to use data & text. Lucky i already have a third party app for a 2nd phone and also use google voice, both of which let me make calls using my data. and if i need to contact someone i can either send a voice/text message as normal.I have read somewhere that i believe blu is trying to get onto the att network. So hopefully they do because ill just switch back sense they are a good phone company. Hope this info helps.:Edit: Even if it is 4g LTE, also spoke with a friend who has a 5g non-flagship whos carrier uses att and she isnt able to make calls from the phone but the speeds are still there. So hopefully something gets fixed because I believe this is some B.S. to lock us out because we dont want to pay for a iphone or samsung

Internet works because it uses wifi. Calls use your provider, they have cut you off. Also, if you use another company SIM and if they own the phone on a 2 year contract, they will lock you out with a PUK Lock. Phone them on another phone, or go and visit them. https://www.google.com/search?q=Blu+V90 ..

try swipe down from top and pushing setting button then accessibility menu. is it set up to unlock by voice or if on you, if not try to access google play from a different device to check settings or reset

Go into Setting - Accessibility and uncheck 'Visually Impaired' or 'Text to Speech'. Actually, Blue call it 'Talkback'. See the video. https://www.google.com/search?q=blu+phone+has+started+repeating+out+loud+everything ..

The blank screen while charging is characteristic of cell phones in general.

1. Touch the icon that says "Phone" on your main screen. 2. Click on the entry for the number you want to block under "logs." 3. Press the menu button on your BLU advance 5.0. 4. Select add to "reject list."

heHello, Two ways you can get back yourdeleted messages from the phone.

1)From the service provider. WHAT YOU NEDD TO DO TO GET BACK THE MESSAGE FROM THEM IS TO CALL ON THEM FROM THE CUSMER CARE CENTER. 2)From the other side that the message was send from. Thanks.

I think the battery is dead or software problem.To check try to keep charger connected and try to reboot if not then contact the local mobile repairing vendor...

I don't think so, you only lose the info on your cell if you make a factory reset. If you can make a back up with an app.
