I have a Keybo and I want to give it to a teenager who can have no access to the internet. Blocking it on the phone will not work if they are able to bypass the lock from their phone. Can/will Telus block it so that this phone can only call and text and have absolutely no way to get online? If not this phone is their any phone that they can do this from. Prefer prepaid but may consider a plan if that is the only way.
