I can receive SMS OTP again.
I contacted
info@heya.sg on 13 Oct 2023. Received a reply on 14 Oct 2023 and escalated to the technical side when the issue was not resolved. Received email below on 17 Oct 2023. I did not change any settings. Happy with the response from Heya.
Hi,
Our technical side has already concluded their investigation on your issue and below are currently the findings:
- OTP was generated from the heya app unable to reach the device due to the error 'Unknown error attempting to reach phone'.
Possible reasons for the error as below:
The phone number is blocked by a carrier as spam. (This has been checked and not a possible reason).
The destination is blocked. (As mentioned in the previous email on the device setting)
The message body is not valid. (This has been checked and not a possible reason)
The phone number is on a Do Not Disturb (DND) list. (As mentioned in the previous email on the device setting)
Please follow the steps below if it will help with the issue:
- try to take out the sim card and clean the gold connectors on the sim card with a clean piece of cloth and reinsert the sim card again.
- Setting under APN “hicard”.
- Network mode is set under 4G.
(If you are using 2 sim cards in the phone ensure both sim card setting set under 4G).
- Ensure VPN setting is turned off.
- Ensure to disabled all P2P applications.
Otherwise, if the issue still persist, there is a possibility the SIM is not working properly and it is causing the issue.
