(Note: Don't get me started on SMS-2FA; I am using Authy for the "real" 2FA for the site; this is an optional "recovery" process, because belt-and-braces is sometime wise).

Trying to turn on a "recovery" code via SMS for an account, to a work phone that is on Voda.

SMS codes not being received.

It's an overseas website.

I doubt that Covid-19 transport delays are hitting SMS (yet!), so probably not that.

Is it worth trying to follow up with Voda? Can I even do that if it's a work-provided phone/sim on a large corporate plan?

@jamesrt If this is an incoming SMS issue from the 3rd party outside of VodafoneNZ network / control then Vodafone can do zero about it

Contact support on the overseas website and get them to follow-up with the SMS aggregator they use

Further to this VodafoneNZ can block and has done so some SMS aggregators if they have been known to route SMS spam and I can tell you now they are blocked for good

Only the A party (sender) side can look into this issue

Might help to mention the SMS sender in case others are having the same issue?

We had an issue with the SMSes we send from our internal systems (to staff, customers) and SMSes from our third party 2FA (Symantec) not coming through on Vodafone. After a bunch of investigation it turned out this only impacted numbers that had been ported from Spark to Vodafone.

This thread has reminded me I need to follow that up as I'm not sure it ever got resolved....

I had this issue when I was ported from Spark to Vodafone.. I've had work port me back to Spark (thankfully) as Vodafone's 4G coverage in Wellington isn't great. Anyway, I no longer have the issue since being moved back to Spark.

Work number; no idea of any previous porting status; it is an 021 number.

I've raised a ticket with the website; we'll see what [if anything] happens. Last time I did that to another site, the only response I got back was 'our logs show we sent it'.

Logged a support ticket; basically got the Level 1 brush-off; and TBH I lack the will to engage any further at that level.

However, they name-dropped Twilio, who must be their provider:

Verify if a different business that also utilises Twilio to send SMS is being blocked

How the hell is the average Joe Bloggs supposed to know how to do that?

Anyway, I will attempt [probably futility] to contact Twilio support; but I'm not going to hold my breath.

I would have major concerns if VF are blocking Twilio considering it's used by some of the largest companies in the world for messaging - I don't believe they are blocking them though as I can confirm Twilio messages are coming through to my VF number.

mrdrifter: I would have major concerns if VF are blocking Twilio considering it's used by some of the largest companies in the world for messaging

I didn't mean to imply they were being blocked; it was more the name drop and/or vagueness of "check if someone else using the same service is blocked" - how would you know?

mrdrifter: I don't believe they are blocking them though as I can confirm Twilio messages are coming through to my VF number.

Thanks; I'm probably any isolated case - maybe the number's been ported previously? who knows? (I know the number has been recently "in use" due to other texts received about low bank balances and food box deliveries - don't get me started on the privacy concerns for those either!)

VF were blocking us sending via Twilio in the past. Had to submit a ticket to whitelist us.

@jamesrt if you want us to send you a test via Twilio, PM me your details. But that might not help if we're already whitelisted. But I think we also have another non-whitelisted number, so can probably test with both.

Thanks, @Delphinus, will PM you.

When you say you submitted a ticket, was that to VF or Twilio? And via what mechanism?

Submitted ticket to Twilio as a vendor, after complaints from customers they weren't getting texts.

... and thanks very much to @Delphinus testing, we can confirm that indeed VF are blocking the texts if they are not specifically white-listed.

Back to the original website (LastPass) to report that; but I doubt their support helpdesk will care enough to actually do anything about it (based in previous attempts to engage them).

This thread might also help: https://www.geekzone.co.nz/forums.asp?forumid=86&topicid=268067

That's the process a few of us went through to get whitelisted at Vodafone.
