Recipient unable to reply due to overseas roaming

For Singapore numbers recipient, the masked sender ID is a 5-digit short code. When the recipient is travelling, he can still receive the SMS except he is unable to reply to the 5-digit short code.


2 Possible Scenarios:

  • Recipient seems to be able to reply but RapidRecall will not receive it. This is because the carrier may have similar 5 digit codes in the host country.
  • The carrier in the host country will reject reply to the 5 digit code because they cannot recognise it.


Ways to overcome when planning activation:

  1. Educate the users to reply to the international incoming number we provide but the recipient will incur international roaming SMS charges.

  2. Use the Acknowledgement link to reply (if the activator has put in the link during activation).
