Messages
Messages can be sent between 2 player. They are sent using /phone message. It is used to communicate private messages.
Cost
Carriers can set how much their subscribers pay to send messages. The set amount is removed as soon as you send a message. If you're currently roaming, the price will be your carrier, plus the peer that you're connected to.
Tip
You can check the cost of sending messages on your, or
any carrier using /carrier info. It will list the chosen
carriers price, as well as the prices of its peers.
Delay
Messages have a delay to them, based on the type of tower you're connected to, and your signal strength, as well as the same for the person you're contacting. Having bad reception will impact the time it takes to send messages, so if you own a carrier, make sure you're coverage is good enough. The type of tower is also important.
Tip
/phone info will you the speed of which you can send messages,
but keep in mind that this does not account for the signal of the
person you're sending to.
Calculation
The delay is calculated using several values. Each tower has
a set delay in the config, which you can check using /tower
info [type]. Then, this value is multiplied by the difference of
1 minus your tower strength (a value between 0-1). These get
calculated for both players, and added together
