Wifi is good if you are station, e.g at a restaurant, office or hotel. It will not work if you are on the go, e.g in a cab or walking or on the go. Most hotels or restaurants offers free wifi to attract customers, norwood world wifi helps you to locate these wifi hotspots. If you dont mind to walk a km to the nearest spot (could be starbucks) to download emails, then is a good solution.

If you need a 3G or 4G data where you can easily use your whatsapp, emails or FB, you will opt for Flexiroam or Telstra which gives you coverage and mobility.
