I recently took out a monthly £6 bag since I was going to France sailing and wished to be able to listen to radio in the evening whilst out of wifi range or with rubbish wifi when in port. After just 2 nights, I got a message saying that I had used 80% of my allowance. I thought that audio was cheap...but clearly I'm wrong. Can somebody tell me how many minutes of listening to radio equates to 500MB?
Does you phone have an FM radio(All my Android phones do).If you use that and disable your Mobile Data connection you won't use any Data but you do have to scan for the Radio stations of the country you are in and can only use those
Do you know of any apps that operate with a lower overhead? Rgds, Peter A
Your best bet for listening to Radio 4 in France is probably 198kHz Long Wave. If you have an RDF navigation receiver, you may find that it will cover 198kHz.
