From the description “Plan period begins upon delivery of SIM – no activation required.”, these SIMs are already pre-activated, ready to use. RW is just tracking the delivery date, not the raw activation date of the SIM.
Thinking this through a bit more, and using the experience of what I already do at my company with sales and working with sites seller backend like Amazon, Ebay, NewEgg…etc,
They could be doing this via the Amazon business seller back-end as the tracking number is stored there and Amazon itself has built in tracking notification system, as also does NewEgg and Ebay. It is easy to export a database, or spreadsheat of fulfilled orders or invoice. They could be using the data from that to read from when setting thier usage timeline for each card. Or, make it automated thing, so when Amazon sends a notification of delivery, this is then read by RW’s systems in some fashion and updates their back-end to log and start that sim cards time line.
Down an dirty way of setting this up…seller platform’s(Amazon, ebay etc) automated email notification of item delivered to customer is read by seller’s own email client or exchange server, triggers a rule or script that reads in certain fields, stores that data, then outputs that data to internal database system/program.service that then reads and makes use of that data to do required task, in this case, start the use time line clock for that data only SIM.
(I have been experimenting with something like this for my company to both digitize our Invoice and Order history, as well as to update our inventory system …it is currently all done on paper manually by hand and data manually entered. Getting different softwares and online services to talk to one another and work they way you want certainly is a challenge. I have a bit of programing and scripting knowledge, so that helps a bit.)
If RW already has a way to track that each SIM card is now active(delivered), and futhermore track the “Plan”, to start it, then deactivate the sim when time is up, or to reset the GB each month for the 90 days, this requiring the sim card’s number. Then, it sounds like to me that they already have some system in place to track and control each data only sim card rest data allotment and kill switch. SO, in theory, the trigger to make the “Plan” start may be possible to set to when the SIM first comes to life in the system/network.
EDIT: I also would like to add the point that some users, like my self, who live in apartment complex, whose packages get delivered to a rental office that is only open certain hours each week. It is sometimes a few days, or even a week or more before we can get packages from there due to our own work hours conflict with the open office hours. Not to mention the office is closed early randomly for staff meetings, showings etc. Very frustrating. Not at all the fault of Repulic, but certainly a concern when an item time clock starts at delivery. When i ordered a phone from RW for my mother, it was delivered to office, it sat there for 9 days before I could take the time off work to get it during business hours.
