How can put them on hold...???
I do not want to be billed for those!!!!
You can suspend them without billing for 90 days, and can do two suspensions within one year. If you suspend without billing and the lines are still under contract, the contract end dates will be extended for the length of time you have the line suspended. There is a charge to suspend a line if you have it done by calling Customer Service; there is no charge if you do it yourself via your on-line My Verizon account.
I also believe the ETF doesn't get reduced during that time either.
