This was the answer to my texting problem at 73 with arthritis and big fingers, phone buttons were becoming a little difficult so only the briefest of text was used sometimes to the annoyance of my sons. SMS had the answers Cost effective, simple,no time scale on usage,no hard sell, very easy to use,convenient as I can do all all my texting with as much detail as I wished from my PC with bigger keys and easy editing and still receive replies to my phone. I Don't normally respond to survey's or reviews but I make an exception in this case,If in doubt give them a ring, they have packages to suite. Very satisfied customer
