Hey @Lily1967.
Welcome to the EE Community!
I've just split your comment into its own thread so we can make sure all the info you're getting is relevant for you.
Like @bristolian has mentioned, having one bar won't necessarily affect your ability to connect to data.
If you haven't already I'd recommend giving your phone a restart, as occasionally the connection can 'get stuck' and prevent you getting online.
It's also worth taking a look at our network status checker to see if anything is reported in the area, too.
