I haven’t received a message today – is there a problem?
The frequency of messages will vary as the plan progresses – it could be that there just isn’t a message scheduled for today. If your phone is switched off or in an area where you have no network signal, the messages will be delayed. The SMS network will make several attempts to send the message, but if your phone remains outside network coverage for a long time there is a risk that the network gives up and the message won’t be delivered. If your phone’s memory is filled by old messages, new messages cannot be delivered until you delete some of the old ones.
