i have a samsung boss mobile
i activated it with a new gsk & it was successfully activated
but after some days suddenly my phone closed my number &
on every call i hear "to resume service ..........."
i contacted service center, they charged 130 rupees & my phone again restarted
they said that this problem is from the board ,change it in Rs. 2100
i said: in same Rupees i can buy a new & better handset & returned to my home
but after some days the same problem again reflected
What i can do?
