I have been travelling somewhat for the company I work for and I had an issue with the crazy usage prices that Bell charges. I have an unlocked Samsung Nexus phone in which I can swap sim cards. I came about this company located in Vancouver that offers an excellent cell phone plans when you travel to the USA. Though you get a new cell phone number where you land, you can use your phone with unlimited calling within the USA and Canada, unlimited texting and depending on which plan you get, a data plan. It worked flawlessly and I constantly had excellent reception and I was able to use my phone to search websites and upload pictures I took. Next time you are about to travel to the states, check them out, they will save you a ton of money when travelling.
