//        if you are sending off ~600 phone numbers I would change things to send them all to the server at once in an array, in one request. then have the server insert them all in a .transaction {
//        you will get much better performance.
//
//        as it is right now you are sending off ~600 different requests in a burst and the server is doing separate transactions for each. that could be your bottleneck - you'd need to measure to make sure (but it's still a good change to make regardless!)
