Thank you mcal3K and AAL08. I have checked the Verizon and ATT but they are both only available on contract terms and not for short period of time. I only need this mifi device for about 10 days whilst in Paris, hence they are not suitable for me.
Yes many hotels and cafes are providing free wifi but the connection normally not that good since many devices are sharing the same line plus we only get good connection at certain areas like lobby etc. I prefer a mifi so that i can get internet connection even when in park, garden, outside building etc.
I am now checking the French Connection and hope this one works for me. Feeling incomplete without the internet these days hoho
