I like the kids plan and would like to keep it but would like to know if there is a way to increase the number of contacts to more than 20?
Just Kids is a plan that shouldn't exist. Cost isn't much different than Start Unlimited which doesn't have such nonsensical limit on something basic such as contacts. Switch the line to one of the regular plans, the restrictions to cost on those plans makes absolutely zero sense.
To Verizon's marketing team: Consider getting a job you're more qualified at like being a clown at a circus.
Akrug30, it is important to make sure you have the best plan that fits your needs. The Just Kids plan allows up to 20 contacts, however there is not a way to bypass and allow for more as it was designed this way to allow monitoring by parents. The next option available would be the Start Unlimited Plan which does not have a restriction on the number of contacts.
