Because corporations have a LOT of power in this country. We all gave them that power.
To me it is crazy that phone companies were EVER allowed to lock out someone else's technology in order for any of us to use it. They should have never had that power to begin with.
Tech/media developers and companies are always 2 steps forward, one back.

Ive been so overcharged for data when I go to CAnada on Verizon. I pay a high price to have a phone and text plan that INCLUDES canada.
T-mobile told me if I am on their 60 dollar plan - I can call and text to and from Canada and get unlimited data there for no additional costs.
So there would be no reason to get any local plan in THAT country with a different sim.
Sounds too good to be true and I get so much bad info I dont know what to believe.
T-Mobile offers a test drive. Get an iPhone 5s and test it to make sure you get good coverage in your area.
