"I had an absolutely stellar experience with Varuzh. From my initial phone call, all the way through his service I was treated with patience and respect. It is such a vulnerable position to put yourself in, to have computer repair work done by a stranger, and finding a truly trustworthy person to deal with can almost seem impossible. On top of that, the vast majority of IT people seem to relish in being condescending and seem to love to make you feel terrible about your equipment etc. Not Varuzh, from the time I called to explain the issue I was having and all the way through his service, he listened intently, offered great and reasonable solutions and put my mind to ease right away. He also worked very quickly and efficiently. And he even went as far as to offer help and suggestions for another family member who was experiencing similar issues. I will definitely be using his help again and I can't recommend him high enough!"

Landline phone services FAQs

Having a landline is often worth paying for, if only for the peace of mind it provides. While some homeowners opt for cell service and internet only for communication, cell towers and internet lines can get knocked out of service during storms or natural disasters. Landlines can continue to work even if the power goes out, and telephone lines are more likely to continue to work in emergency situations. Paying monthly for a landline might seem like an unnecessary expense until you need it, at which point it could be invaluable.

The average cost for a single landline in your home is around $24 per month, but some carriers offer lines for between $12 and $40 per month. If you also want access to cable TV and internet, it’s often more affordable to bundle services with a single carrier. The average cost for all three is around $80 per month, and prices for different bundles range from $50 to $150 or more, depending on what’s included.

You can check with neighbors to see which phone service—if any—they have and whether or not they’re satisfied with the service. It might be faster and yield better results, though, to use the tool above to search for the top-rated phone service providers in your area. To double-check the quality of service, you can read through online reviews for each provider.
