We have two unlocked phones: an iPhone 4 (unlocked by Apple) and a Blackberry.
We will be in London prior to coming to Paris and am planning on getting O2 SIM cards and "pay as you go" plans there. I want to get something similar in Paris, but haven't been able to find any English sites that made any sense.
I will be arriving at Gare Nord and will be staying in the Marais area.
Can somebody suggest a carrier and/or location where I can get SIMS and plans for both phones?
