CallingCards Boost

BO6 calling cards boosting is a service that gets a skilled CoD player or team to help customers improve their game character. We can handle the process in piloted mode (account sharing) or self-played (play with a professional team). The services are completed legitimately and professionally without using hacks, bots, or manipulating the game's code.

When it comes to prices, at KBoosting, we have fair prices, which reflect the work and time needed to invest to obtain the goal the client wants. We try to keep our calling card unlock prices as low as possible, and please keep in mind that every BO6 boosting service provided by KBoosting is handmade, without using illegal 3rd party software, cheats, hacks, etc.

Yes, at KBoosting, you can buy calling card unlock services, and we guarantee the completion of the desired service safely and efficiently.

Usually, the calling cards unlock service starts a few minutes after the order is placed and the payment is processed. There are some exceptions, though, such as when we might be overloaded, and the service request is very high. Even if we can’t start working on your order immediately, the manager will let you know when we can provide your BO6 boost.

Most calling card unlock services can be delivered in 48-72 hours, but exceptions exist. If delivery time is crucial for you, some services have the "express" and "super express" extra options, moving your order in front of the queue and speeding things up by about 30% or even 60%.
