Even though mobile carriers promise 'unlimited' calling, often in their user agreements they hide (in fine print) restrictions on this 'unlimited' calling.  
Unfortunately this adversely effects some of our most dedicated callers: the elderly, the remote, and the blind. These are listeners who are more analogically inclined, physically cannot use a smart phone, or have limited mobile internet access in their communities.

In order for your listeners to all have access, it may become necessary to change your Call-To-Listen number.  Depending on the carrier we might have to change this number every week, for other carriers, we have had the same number for years.  
We do give you one number that never changes, but some of your listeners, when they call in, may be directed to another.  

Did this answer your question?
