What to do if the customer can’t receive an OTP (LiveLink)
If a customer enters their phone number on LiveLink but doesn’t receive the one-time passcode (OTP), use this checklist.
1) Confirm the phone number format + country
Make sure the correct country is selected in the dropdown.
Re-enter the number in a clean format (best practice):
+<country code><number> (Example: +447911123456)
If they copied/pasted the number, remove spaces/symbols and try again.
2) Confirm the number can receive SMS
OTP is sent by text message, so it won’t work if the number can’t receive SMS.
Ask the customer:
“Is this a mobile number (not a landline)?”
“Are you currently traveling or roaming?” (some carriers block SMS abroad)
“Do you have SMS short code / international SMS blocked by your carrier?”
3) Check whether the country supports OTP/SMS
Some countries or number types are not available for messaging.
If the number/country is not supported, the customer may be able to continue using an alternate method (example: email-based contact/updates), but OTP by SMS will not deliver.
4) Basic device checks (quick wins)
Have the customer try:
Turn airplane mode on/off
Restart phone
Confirm they can receive any other text messages right now
Check spam/blocked messages (some Android SMS apps filter unknown senders)
5) If it still fails
Collect the minimum info needed for Support escalation:
Phone number with country code
Country selected in LiveLink
Timestamp + customer timezone
Screenshot of the OTP screen + any error/warning shown
Whether the number is mobile vs landline/VoIP
Whether they’re roaming or using a dual-SIM number
