If you wanna share your moments in Paris with the world in real time and don´t want to miss a thing from your tour, you can´t waste your time by getting into every Starbucks to use wifi! There are many options for prepaid plans!
I got it from Orange, one of the largest operators of mobile and internet services in Europe, and chose the “max” plan valid for a month that costs €30 and includes unlimited call + SMS in France and 2gb mobile internet. I found the service very good and recommend it. The only problem I had was in finding an Orange store that had not ran out of the SIM card. On a Monday afternoon I went to two stores (one on Champs-Elysées and another on Boulevard Vaugirard) and both told me that they would receive it in a couple of days… I couldn´t wait that long, so I had to search for other stores in town and finally managed to buy it at Orange – Place La Madeleine.
Great service! The attendant spoke good English and helped me to set up everything, so I left the store connected to the world again! A few weeks later I ran out of internet before my plan was over, so I easily purchased a recharge card in one of those tobacco shops.
Tip: even using the new chip, you do not have to change the previously number registered in Whatsapp. When you open the app, click to continue with the old number instead of inserting a new one, then you will have access to all pre-existing contacts and also add new ones.
