If you've paid a low price for a phone it is because the price is being subsidized by the cell phone company because they tie your purchase of the phone at a cheap rate to the service. I see nothing at all wrong with this.
If you want to pay FULL PRICE for a phone, sure, you should be able to use it on any service. But if you get your phone free or at a severe discount because it is tied to the service, you should be required to KEEP that service for the length of the contract.
I am trying to figure out what any of this has to do with Obama’s constitutional obligations.??
If you’re ever in Berlin, go to Sonnenallee. Find any Turkish or Arab electronics store (trust me - you can’t walk 20 feet without seeing one) and ask them to unlock your phone.
Ten minutes and ten euro later, you’re good to go.
I’ve never bought a locked phone in Continental Europe: I think it’s actually illegal per EU consumer law.
