For our MyPlan options you would need to select either Pay per use Calling at 50 cents per minute, or a monthly voice package for local daytime calling. If you had Pay Per Use, you would be charged for all calls made to other MTS Customers. Do you have a plan with us now that you are looking to make changes to? We would certainly be able to review your options in more details if you want to send your Wireless account details to firstname.lastname@example.org for us to follow up with you. Thanks!
