Sim Free Mobile Solutions Provide Freedom

I have carried a mobile phone for years and years.  I am a businessman that travels frequently so I really need one. I end up staying in different cities for several weeks at a time and I find it more convenient to talk to my wife and kids with a cell phone.  The convenience is nice, but the roamingcharges are not.  I was complaining about the cell phone bill to my wife when she suggested I use a Sim free mobile phone.  I can’t believe I had never thought of this before.  This solution is already saving me plenty of money.
