Got the Sim only deal from Vodafone Hounslow store giving me Unlimited calls, Unlimited text and 20GB data for £22.20. Also, as I normally travel europe a lot they have also given me free roaming (unl calls, text and 4gb data).
I have also been offered to choose one of their entertainment packs ranging from sky sports or Spotify or NOW TV free for 12 months.
The normal price is £37 but they have given 40% off which makes it £22.20. Great offer for new and existing vodafone customers.
