Hi domfern,
A warm welcome to the eForum!
The SFR network has 3G and you should be able use your
Vodafone modem in France with no problems.
We can’t however guarantee that the network will be fault free and as we have no control over their network, can’t fix any network related problems that may occur at that end.
I’m sure however that if any forum members have any advice or feedback for you regarding this then they’ll let us know.
All the best,
Jenny
