There is also "Local With More". Please see https://www.xfinity.com/support/articles/voice-callplan-overview for a feature comparison. The price is somewhere between between $20 and $45/mo. Contact customer service for the rate for the plan you are interested in, or get one of their price sheets. Service Centers should have them (check locations and hours at http://www.xfinity.com/support/service-center-locations/), or have customer service send one to you.
Use the price sheet as your starting point, and then check the web site, customer service, and this forum for special deals not listed on the price sheet. Shopping their products without the price sheet is like groping in the dark.
Pricing for most packages may have been included with one of your recent bills. Check https://customer.xfinity.com/.
I really appreciate your response.
I hit the "kudo" button .....no luck there.
I also tried to the "emoticon" feature. No luck there either.
But hey, the least the spell checker works.
