Further, some technical issues that have surfaced during implementation of the initiative include non-delivery or late delivery of SMSes either due to problems at the bulk SMS gateway provider or because of service glitches at certain telecommunication providers. When a message is not received at the targeted time, the Mobile Learning team generally waits until the following day to see if it is a permanent failure. In such cases, the same message will be reset for the following day and the subsequent SMS is also rescheduled if it was scheduled for the day after the failed SMS.
