My wife and I are on a driving tour in the south England. Much of the parking requires coins or the RingGo Parking App. It seems that the app will not send a verification code to a US number. We have tried numerous iterations of the country code +1, 001 000,1 etc. No SMS code.
There is a phone number to call to pay by credit. We did that once when we didn't have enough coins. It took 3 tries before it took our information and it required us to call a second number.
Any ideas? Thanks!
