I wanna know how i unblock phone numb

I have a boost LG phone that will not allow me to text its block certain numbers

I want to switch to boost
I heard that their phones are locked
So if I want to leave them for any reason(like if the service is too bad)
what is going to happen to the phone?is it possible to unlock it?
I'm thinking of buying an iPhone from them since it's 100$ cheaper than others

Hi there!

Simply install call and SMS blockers that you can find in Google Play store. There's a lot of them. I suggest that you install a lot of them 'til you find what you need. :)

How do I block Incoming messages from certain numbers on my phone?
