You need to call T-mobile to have them refresh your sim card on the network for the reception issue.

If the duplication keeps happening you need to perform a master reset on the device. If that continues your phone probably suffered the effects of a power surge while plugged in. There is no fix for that except maybe flashing the phone.

it is always recommended to use branded charger...

PUK code (0 left) - Need Code

Hi,it is your sim card which is blocked as you have entered the pin code wrongly 3 times,

It is easily solved by contacting the network provider of your sim and requesting the PUK code for which there should be no charge,

Some networks will have this service available online if your check on their website,you put in your mobile phone number and it will generate the PUK code,

If you are unable to find it on their site you can ring them and they wll be able to assist you with it,

Do not try guessing random codes as after failed attempts at inputting the wrong PUK your simcard will be permanently blocked and need replaced,

Just noticing you say in your question (0 left),is this referring to no attempts left? Have you already tried 10 times to guess the PUK?

If this is the case your simcard is now useless,but your phone is fine,it will work with another simcard,

If it is important that you have the same mobile number you will have to request a new simcard from your provider and they may charge for this

I just got the same problem, it's just because the battery is so dead it needs time to re-charge. Just leave the phone plugged in for a while, it will eventually show up as charging :)

Have your tried taking the battery off to reset the phone itself? You probably need to go to your t-mobile store and have the button/ phone replaced/repaired... sorry

T-Mobile Dash screen won't light


You can open it up and see if the lcd cable has come loose.

The following link provides directions on how to replace you screen. You only need to go to step 7.
After resetting the cable, and it doesn't work, then you probably need a new screen. I provided a link below where you can get those.

T Mobile Dash

If you are a current T_Mobile customer, you can call them for the unlock code directly. If you have been with T-Mobile for at least 90 days, and have owned the Dash smartphone for at least 15 days, then you need to contact T-Mobile Customer Support by calling 1-877-453-1304 toll free. If you are outside of the country, the number is +15059983793. The representative will ask for your phone's IMEI#, which you already have, then they will process your request and email your unlock code to you within 48 hours.

I own a Dash myself, and I just had my phone unlocked last week.

Good luck!
