If you have a voice line with Verizon, there's a good chance your bill is set to increase by $1.35 starting next month.

As The Verge reports, Verizon has decided to increase the administrative fee associated with each voice line by $1.35, taking it up to $3.30 per month. Nobody likes a surprise increase, but it's made all the more frustrating because Verizon isn't explaining exactly why customers need to pay that extra $1.35.

In an email to The Verge, Verizon spokesperson Adria Tomaszewski said:

From time to time, we review and make adjustments to fees to defray some of Verizon’s administrative and telco expenses and costs of complying with regulatory requirements. To that end, Verizon Consumer will implement a change beginning in June.

That's clear as mud then.

Business customers should also brace for a price hike. Starting June 16, Verizon will introduce a new "Economic Adjustment Charge." It means there will be an extra $2.20 to pay per line for every smartphone and data device. Basic phone and tablets will pay an extra 98 cents. This new charge is due to the "current economic conditions," and Verizon's attempt to offset rising costs.

Verizon is sure to get more than a few angry phone calls regarding the $1.35 increase. It would help if the company actually explained why the increase is required, but I suspect that won't be forthcoming however angry someone shouts down their soon-to-be-more-expensive voice line.
