The easiest answer to these problems is the following:
if you need a service that provides reliable delivery of messages
then contract for that kind of service. SkyTel's 2-way paging
service is one example of a service that will hold messages until
the pager is able to confirm receipt.
AT&T also has a similar Text messaging service with their digital
phones.
One-way pagers are not reliable. You cannot guarantee delivery of
messages to them. Therefore, if reliable delivery is required
then a one-way pager is not an acceptable solution.
