Okay, i dont know to describe this but here goes:
i have a samsung phone, and it was working fine, i was txting and all was good, until it just turned off. so i turned it back on again, it was okay for 2 seconds, but then it turned its self off. its been doing this for about 30 minutes now
i dont know what to do!
also, when i got my new phone, i got a new sim card, and was meant to put that new sim card into my phone when my current sim card stopped working, however this never happened...so i then tried putting the new sim in but the same thing kept happening...

any ideas ?

thankyouuu x

sounds like a battery issue... does it work with a charger plugged in (best give it 5 mins charging before trying to turn it on again)
