Can you survive Japan with no voice /data roaming using free Wi-Fi Hotspots only?  Yes, you can!

On a recent trip to Japan, I had to face the inevitable hurdle all data roamers face to avoid astronomical roaming charges, especially when traveling outside the EU: Contact my mobile operator and find out the roaming packages they offer.  And while I’m on hold waiting to speak to the next available operator, I wonder if these packages will be price sensitive, what type of pricing model they will apply (per MB, per KB, or else), and will I need a calculator in my hand when using data?

Voice is a given, a commodity, a service that is always there and available.

It’s been a while since the major mobile network operators (MNOs) in Europe first started deploying LTE.

Over here in Italy, the MNOs advertising campaigns on their 4G/LTE networks have been endless. They started before the networks even launched and they have been promoting them long since they went live.

Even though 4G is not available in all areas, it is found in major cities and it is gradually expanding and getting new subscribers.
