5 hdc S4 legends no service error
I bought 6 HDC Legends S4 at different times. 10 days ago 5 of them stopped receiving signal from my cellphone provider. I tried different sims from different service providers, but all same problem.
It can not be a coincidence that 5 stopped working at the exact date. Two was bought 3 months ago and 3 last week.
Any idea if there is a setting in a system file somewhere that I have to change.
The 6th phone is working fine, so it can not be a network problem.
Please anybody, I need to sort this out urgently.
