What do SIM order statuses mean?
Placed - order was created in Twilio's system, but not shipped yet; orders are usually shipped between 2 and 4pm PT
Shipped - order was shipped and is still in transit; the tracking url in the Order Items page will provide the current status and expected arrival date
Completed - the delivery carrier reports the package as delivered.
In general, SIM activation/deactivation should take around 60 seconds; however, there are occassional activiation queues that can cause delays in SIM activation and deactivation.
A comprehensive glossary of SIM status values can be found in the SIM instance documentation.
