Say what you will about land-line telephones but I will say that its way more reliable than your mobile. I also think its worth the added expense. There are phone lines in areas where there is zero cell service. You can also make unlimited calls with the exception of long distance which in some places there is still a charge especially for overseas calls. We have our local power provider as our cable, phone and Internet provider along with T-Mobile as our cell provider. Our land-line phone is rock solid, time tested technology.
